LOS update -- new development

I am currently tethering over a 4g connection, and my internet is working fine, BUT I have a complete LOS for the cell signal. I think this could be a very important fact because we should be able to know some things by the fact that WiMax is working while the cell signal is altogether lost.
Hopefully, with this info, a solution is a little closer at hand.

Ok...when people say LOS do they mean Loss Of Service? Or Loss Of Signal?
Because if its the latter, that sht aint that bad. But if its the former...I'm glad I don't have it.

It is bad. People that get it have to reboot phone for it to come back and it kills battery life. Nit to mention missed calls and texts. It is a complete loss of service.

Its 2 separate radios..

I had pandora going over 4g earlier for hours...but lost signal with a crossed out circle after about an hour. Pandora kept going but u couldn't make a phone call, ths.falls in line with the other poster. Im running eg30plus over latest 2.1 midnight.

As WhiteWidows stated, it's 2 different radios. The LOS people have posted over and over about is the ability to make/receive calls (which is what the OP posted about). The Wimax radio (4G) doesn't transmit phone calls. That's why you can do data on 4G and still make a call at the same time.
.....

Hi guys, this is one of my first posts but I've been a long time reader coming from the Evo 4G forums. I'm rooter using Zedomax v3 and experienced multiple LOS as well.
Last night I tried limiting the clock speed to 1ghz and setting the min at 400mhz. Strangly I now get slightly better reception and never had a LOS yet. Will continue to test out this theory and see if it's clock speed related.
I came about testing this since I ran mine at 1.6 for a while and not only would I get more LOS occurances, I would also get phone freezes lol. I tether and stream music a lot so wanted to keep it slightly underclocked to keep the temps down. Hope this helps as a temporary band aid for the LOS bug

It definitely makes sense that the two radios are separate...the point of my post was just to offer some more information to help figure out a fix.
If one radio fails while the other stays working, do we know that the problem is phone-related? Many posters have speculated that the issue may be on Sprint's end, so I wasn't sure if this info did anything to challenge or support that theory. Maybe it does nothing, though -- just throwing it out there!

Someone posted a log cat of a LOS. There's still some coding in the radio files that thinks there is a sim card. Says sim disconnected and result radio off

Hopefully a solution is found soon, I've seen similar issues posted on various android forums. Androidforums, Sprint community and here. Wish I waited a bit to hear more user experiences....

Has anyone tried editing the build prop to manually change the preferred network from wcdma to CDMA auto? Maybe that'd fix that issue

I have been on my current SGS2 stock out of the box for over a week now and have not had any LOS issues, or missing texts, or data not working, or missing phone calls, etc.....
I have been using wi-fi, 4G, 3G, have an Airaive, went to an area where there is no Sprint service and phone roamed fine and then went back to Sprint service when available.
I have been unable to replicate the LOS issue on my current phone through all possible ways of using it.
My first SGS2 was also fine until I rooted it which then gave me an LOS within 12 hours of doing so.
If someone has a another sure way to get an LOS, I am willing to try it on my stock, never rooted phone but I don't think there are any other situations I can try that I haven't already......

Time.I have went 3 days without a los then 2 in same day.It is all random

Signal Strength on E4GT ICS Is Erratic

My signal strength is jumping around like crazy...from -106dBm then back up to -64dBm...and everything in between, in a matter of seconds. This has been happening since FD24.
I have been using Sfhub's stock rooted nodata roms. I tried the FD02 kernel repack with rougue recovery on FD26 rom & modem, and it seemed to jump around alot less.
Could the kernels be the issue? Or the modem? or the Rom itself?
Update for FF02:
FF02 seems to be better for now...will do some tests later. I had it jump around only once yesterday.

Try throwing your phone at the wall, fixed mine

If it is jumping fro -106 to -64 and back, it is probably scanning because it lost signal. When you first boot your phone, often it exhibits the same scanning behavior.

That's what I figured...and that fact is absolutely murdering my battery life.
You think a data reset will help?

I wouldn't say there is a great chance, but the possibility exists.
The "cleanest" install possible is the following:
1) install Full ODIN OneClick
2) remove external sdcard, if any
3) from android, format internal sdcard
4) from android, perform ##786# reset (providing your MSL, which can be retrieved via "getprop ril.MSL" from terminal or adb shell)
If you format your sdcard, make sure you move your backups to your PC or other external storage.

What does the ##786# reset do exactly?

It resets NVRAM as well as your Android user data.
You dial ##786# in the dialer on a stock rom.
It will reset stuff like your phone #, your data login, and other values stored in nvram.
It will cause your phone to perform hands free activation at the next boot, which will populate that information again as well as update profile and prl.
Hands free activation only works on Sprint's native network so don't do it in a place where you can't reliably get signal.

Anybody else having this problem?

happened to me right after i flashed fe07 modem. i moved back to fd26 to see if its the towers or modem. all seems fine, but i will be keeping an eye over the next day.

FE07 had absolutely abysmal 3G data speeds. It took so long to download the Facebook app update that I immediately flashed an older modem to check against it - FC24 runs like a CHAMP.

I tested fe07 for a day or so. I didn't notice much other than it would drop to 1x often. I ran a speed test 3/4g between fd26 and fe07. Fd26 clearly performed better for me. I went back.

Still rockin EL29 here. All the new modems sofar for me have sukt dik. And YES I let them settle in B4 pulling any test. SOOOO I dont want to hear the BS here, like whatwent on with my other post in a similar topic. Yeah got me sum points taken away..lol..

Try ta tell that to some of the fools in here. Then bam a mod from a completely diff forum or wherever he is from hands me a infraction. Oh well. It is fun to flame. Fuk um.

Lol

I don't discuss modems because for every release 1/3 think it is better, 1/3 think it is worse, and 1/3 think it is the same.
No matter what you say, some people are in violent disagreement.
Just pick what works for you.

Fe07 is the best ever in history until the next best release!

I got the "you roamed too much call" yesterday. I don't force roam ever because I'm in FL and force roam doesn't work here with sammy phones.
I was running several of the recent modems last month and used 5GB of data roaming. Almost 100% of my data. Was the first and only month this has ever happened....in 8-9 years. I reverted back to older modem and roaming stopped. This was on top of the fact that I keep wifi on at all tines at home because my house is a dead spot. I also have an air rave (whatever its called).
I only listen to music, email and surf web. Quite surprised by the call.
I explained to rep that I only go to work and home. That for whatever reason home and work are dead zones. Of course he checks and tells me coverage is great in my city. Then he says sprint can boot me, or I can ask to switch for free. Told him I didn't want either. His solution was for me to put setting for roaming sprint only. I asked him how I would use my phone if I only roamed sprint? No answer.
Very frustrating since I wasn't force roaming, have 6 lines and can't afford other carrier and I actually like sprint.
Sent from home How do I turn my phone on?

My phone came with El29, and after seeing loss of signal often I started experimenting with modems. Tried fd19, fd24, fd26, and fe07, and I still get bouts of loss signal. It's not an issue of bad reception, because my OG epic has no signal problems.

Hows the signal on FE10?

How to Increase Signal in my Apartment?

I recently moved in to a new apartment for college and unfortunately my signal is very poor while inside the building.
This is really the only place on campus that I don't get great signal unless I get close to the window and pray that my phone decides to connect.
I've briefly looked into possible solutions but wanted to see if anyone had any suggestions/opinions on what I should/ could do.
I briefly looked into the Sprint AIRAVE, which I should be able to get. However, unless I can get it for free then I really don't see it as a viable solution, especially since my contract is up soon and I can just move to another carrier.
At this point I see my options being:
1. Get the AIRAVE.
2. Purchase a 3RD party signal booster (If cheaper than Sprint one).
3. Come up with some kind of DIY solution
4. Change some things on my phone in the hope that it improves.
5. Switch to another carrier.
What do you guys suggest doing/ think is the best option?
Are there ay other options I've missed?
Current Setup on my Epic 4g:
Rom: CM9 STABLE build from 8/10
Kernal: Shadow v0.6.3.3
PRL: FC09

I suggest option #1: Call Sprint and throw a fit, and have them provide you an airave

You may be better off with option 5.
The Airave is more of a cop-out solution for Sprint and their craptastic network. However, if it works for you then by all means go with it.
I've been with them for over 10 years now and haven't seen much network improvement in my city in the last 5 years. There are big patches of dead and weak signal spots all over. Hell, I can step outside my office building and find a dead spot in one 5 foot span, then move out of that span and be in a 3-signal strength spot.
I'm waiting a bit longer to see if their network will improve in my area. Otherwise, I will most likely jump carriers.

My family has used them for about 10 years total, with a brief break when we lived in england. I've never really had any problems with getting signal where I needed it before now. But yeah, at this point they better make a good offer if they want me to stay with them.

So I called sprint, they wanted me to go through some troubleshooting stuff and ended up asking me if I was rooted.
I had a bunch of back and forth with him and he claimed that being rooted/not on stock caused my phone to show no "vital signs" and that even if I am using the proper PRL it doesn't matter. Everything he said sounded like a bunch of policy stuff and he never gave a clear explanation of why it mattered if I am rooted. Anyways he said I could restore to stock/factory settings and then he would call me back latter and we would troubleshoot stuff.
I am going to be doing the flowing:
1. Backup everything
2. Odin back to stock (non-rooted + update)
3. Go through the troubleshooting, even though I know it won't make a difference.
4. Hopefully get the AIRAVE for free.
5. Go back to my current setup.
I've also noticed that turning 4G on may actually make a difference in signal (Since there is 4G in atlanta).
Does anyone have in thoughts about this?
Am I wrong in saying that being rooted has NO effect on connectivity?

If you do anything with Sprint that involves troubleshooting, you should be on 100% stock. Also, never admit to rooting, even though there is that PDF from internal Sprint mail around these forums saying it's basically okay for customers to be rooted. It's way easier to just get back on stock and step through troubleshooting, than dealing with a script following CSR on the matter.
It takes an experienced flasher all of 3 minutes to get from stock back to previous setup or a new custom setup. So not a big deal.
Turning on 4G is an entirely different radio; hence you would have differing signal strengths from 4G to 3G.

Maybe try the nexus modem and see if that improves signal. Some people say it has and got rid of dropped calls. Samsung is notorious for making awful modems, but Google made the Nexus one, so it is better for me and most people who have tried it.

I know really shouldn't have admitted to being rooted but I think I kind of wanted to argue with him about it, just to see what kind of reasoning they give.
And yeah, flashing back to my previous setup shouldn't be too hard. I already know for a fact that going to stock won't solve the problem,
I'm still testing the 4G thing since I can't really confirm if it is actually boosting the signal or not.
___________________________________________________________________________________________________________
@xboxfanj: I thought about trying that the other day. I have to be on a CM7 rom to use it, correct?

Now there is a patch for CM10 as well. Nothing yet on stock or CM9.

Yeah I noticed that. I tried switching to PA1.99 and using the nexus modem but it didn't have any kind of effect in my apartment.
So I odined back to stock fc09.
The Sprint rep called me back, I told him it didn't have an effect (because it didn't).
He agreed to send me the AIRAVE at no charge so I should hopefully have it in a week or so.
After I get it all setup I'll update this thread with details as to whether or not it actually solves the problem.
Now time to root my phone again...

Received the AIRAVE today. Took a little bit of fiddling to get it setup right.
I now get pretty consistent signal, generally 5 full bars, throughout my apartment.
My only real complaint is that it decreases my internet download speed from over 100Mb/s to around 40Mb/s.
The decrease is unavoidable since I have to use the AIRAVE router functionality in order to have it and my computer hooked up.
However it did seem to increase my upload speed by about 5Mb/s once I increased the limit it had set by default.
It also seems to causes me to receive texts twice but that may have just been a one off thing.
Overall it has solved the issue and since it was free I can't really complain.

The double text is an occasional thing and probably will never happen again. I hooked my airave to my router instead of the modem as suggested and it works just fine and does not interfere with my throughputs.

This is how I have mine set up and it works perfect.

Mine is setup so that the AIRAVE connects to the wall and then to my laptop (it's probably hooked to a router/modem somewhere but it's dorm internet so I have no control over that).
It would probably be faster if I hooked it through a separate router but I don't really want to spend the money on one, and would need a pretty decent one since my school has one of the top 10 fastest internet connections in the country (if I had to guess number 3, behind the pentagon and google fiber).

Defective Radio?

I have been having a lot of problems with my new honey, namely in the signal department! I went through a whole thing with it right after activation...it worked, then didn't, then did...etc. A chat session, phone call, & 2 trip to the actual store (all in 1 day!) resulted in them doing a factory reset and sending me on my looney way. It seemed to have helped, for about a day and a half. Now it is dropping signal again! It seems to do so, sometimes, when I have the wifi on. But then sometimes not (I'm not sure if wifi is culprit or coincidence.)
The ATT store employees said I may have changed a setting (I'm sure I didn't as I don't know of any setting that would even cause that!) and also "explained" my signal will naturally fluctuate...(They think I am an idiot, obviously and of course the phone was working fine when I was there...duh!) They also gave me a new sim card.
I *really* want to love this phone! But I'm finding it frustratingly undependable. Texts won't send when I need them to. I'm not getting them either, always. Voice is hit or miss when it drops (sometimes it works, sometimes not.) I have ALSO noticed the signal is not as strong as my old beloved Cappy. That thing was a horse (and I'm thinking of going back to it if this new one doesn't wise up!) Seriously, $300 bucks for a brand new phone & it can't keep a proper signal?
Is it the radio? Is it the software (still 100% stock, unrooted)? Should I make them give me a new one? What if it doesn't work, either? Flashing it to fix the issue is fine for me, but I've been holding out for multi-view before I get flash-crazy. lol Not to mention I may have to return it so better to not mess with it [yet]. I'm very frustrated & tired of getting looked upon like I'm the typical woman idiot who is not as smart as her new smartphone!!! I am NOT imagining it!!!

Sounds like your antennae is shorting out or something like it wasn't soldered properly or the cable isn't secure. Would explain why WiFi affects it. I'd go there and demand a replacement and if they don't wanna budge your within 30 day no questions return. Then go to a diff store and get a new one. I really don't see it being a software issue.

Is it possible that whatever the problem was, it miraculously resolved itself? I had it drop signal two more times since this post, then nothing since. It's been working perfectly. I hate to keep it if it might arise again but I hate to return it if it was some weird fluke thing.
This may or may not be related to the above problem: has anyone noticed their reception is not as good as on a previous device? I had a Cappy and it always got great signal. I noticed this one is not as strong in the same places I previously visited with my old phone. Although admittedly, it seems to be improving. Does that even make sense or is even possible? Just like me, my phone has to be the goofball of the bunch!

You spent enough money on the device, you should be absolutely happy with it, not apprehensive. If you wait past the return date, it's going to sit in the pit of your stomach for 20 months and ruin your enjoyment of it until you can upgrade again. Not worth it. Smile your brightest smile, walk into the store, very nicely tell them that you've had multiple issues and the AT&T phone reps said to go in and ask for an exchange. That's it. They're going to count on you being intimidated and going away. Smile, be nice, and don't be intimidated.
If they say you have to reproduce the problem, invite them to spend the day with you. The Note 2 is amazing and you shouldn't settle if you believe your hardware is having problems.

Smile your brightest smile, walk into the store, very nicely tell them that you've had multiple issues and the AT&T phone reps said to go in and ask for an exchange. That's it. They're going to count on you being intimidated and going away. Smile, be nice, and don't be intimidated.
If they say you have to reproduce the problem, invite them to spend the day with you. The Note 2 is amazing and you shouldn't settle if you believe your hardware is having problems.

Yes. I have decided to take it in later today, as my 14 days is up on Friday. I hope they have stock of them. Anyhow...I have another question. If a phone is sitting still with no movement (and the weather is good, lol) will there be variations in signal strength? I get 3 bars with 4G showing, then it drops to one tiny bar. Sometimes the 4G disappears then reappears. The it will go back up to 4 bars. All in the course 5 minutes! I do realize signal will vary with movement but will it if your phone is just sitting there?
I am trying to experiment a little. I just realized/remembered that I had (uneventfully) dropped my phone (not hard, in-case) about the same time as my dropped signal problem pretty much resolved itself. So then I was like, hmm, maybe there IS something loose inside. I've tried gently shaking/jarring it here on my desk, coincidentally with the bars dropping back to just 1 as a result. But then again it may be coincidental as they are seeming to waiver A LOT. I just wondered if it is normal.
I never really stared at my old phone (Galaxy1) here at my desk but I'm almost positive it always had more than 1 bar at this same location and I never noticed it waiver like this one. But like I said I never had to make myself stare at it to check, either! lol Just wondering if someone knows a little more about cellphone signal 101 than me.

I have the issue of no 4G HSPA+ but I can get a strong LTE signal when in an LTE reception area. I'm wondering if you are in an LTE area and can get LTE? Where are you located?

I have noticed problems with my GN2 as well. Mine shows I have signal but my data stalls or doesn't seem to work as it should. I'm in an area where there shouldn't be any problems. Only seems to happen in non LTE areas. Whenever I have LTE signal this thing is blazing fast.

Update: Took the phone in. Basically, they had never heard of the issue with this phone. But...I walked away with a replacement. So far so good though I've had it only a few hours. The girl was very nice & explained even though I was borderline limit she would take care of me. I told her I received it Fri the 9th but she said they were basing the 14 days on the 7th! I said I didn't physically have it till the 9th! Jeeze. Moot point since she was going to take care of it anyhow but it just concerned me how (corporate) att could chop 2 days of my in-store return time!
So no, I'm not in LTE land, unfortunately. 3g H+ & E only though I can't complain about the coverage or speed. Good enough for me 4 sure.
The signal bars waivered quite a bit even while in the store. They said while some fluctuation is normal it shouldn't be as much as it was doing especially with the close proximity of the tower & good weather and especially while just sitting on the counter.
I downloaded the free app "No Signal Alert" from the Play Store. In just a few hours it recorded lost signal 4 times! (In a very good coverage area) [my first phone b4 the exchange] Consider using it if you want to see if you are losing signal like I was. Handy app!
Hopefully this is a good one. I know it sounds goofy but this phone seems to even move faster than the other. Weird. It will be interesting to hear if anyone else is having this problem. Maybe there was a bad batch of them or something? Like the Nexus I read about & their signal problems.

Haha im glad that they helped ya! No its not goofy or silly to think that one phones faster then another because no two phones are alike. The silicone chips are very different and performance can very greatly. I had an s3 that wouldnt take custom kernels to save its life but I got it replaced after a two year old and a toilet incident haha and that one took even the most abusive settings in stride!

I have a similar situation with mine. LTE will be working fine but then I notice that once I connect to my home wifi and then either leave my wifi range or turn off wifi the LTE icon will show in the status bar and it will show that it's sending and receiving data but Web pages will stall and never load, Play Store will timeout, and SpeedTest.net will start up but the needle will freeze about 1/8 of the way up indefinitely. I've toggled data at this point but it never fixes it, I have to restart the phone at which point LTE works perfectly but once I get back on my wifi the cycle will repeat, this has happened reliably for about the past week.
Do you all think I have a defective radio or am I missing something? I'm still within my return Window and will probably swap it Friday.

Sounds very similar to how mine is acting. I'm wondering if it is the ATT smart WiFi app causing the problem. Shows data incoming and outgoing but stalls.

That's exactly how it's acting for me. I just now disabled the AT&T Smart WiFi app and after a quick restart and toggle test there was no problems, but I'm not sure if the problem will only pop up after I've been on wifi for a while. I'm going to see if it keeps doing it tomorrow.

Disabling Smart WiFi appeared to fix the problem.
Sent from my SAMSUNG-SGH-I317 using Tapatalk 2

What I noticed today is that when this same issue happens, with 4G icon and wifi icon both active, it occurs after I manually check for a firmware update within the system settings. The 4G icon doesn't go away until I reset the phone.
Also I manually deleted the all the AT&T boat ware apps before this was happening so the smart wifi app is not causing this for me.
Sent from my SAMSUNG-SGH-I317 using Tapatalk 2

Weird, if you get the issue and don't have the Smart WiFi app then it must be something else and it was coincidence that it worked normal for me today. I've only checked for firmware once (when I first got my phone) so it must be something else causing it. I'm hoping the multi view firmware will also have a fix for it.

[Q]4G data speed very slow during call

Hi, I have a galaxy S3 with T-mobile. I'm in a place where I have excellent 4G speeds (about 5-6 Mbps :speedtest), I noticed that when I'm on a call the 4G data speed drops to useless speeds. I can barely open a website or download an app. Speedtest shows like 500+ ping and about 500kbps download which is NOT constant (goes up, stops, goes down, etc). Real speed is way less than that. Websites don't open or take forever.. Is this normal? I am using stock rom (but also happened with other roms). I went back to stock thinking that this was a problem with other roms only, but the same thing happen with stock rom. Any ideas/clues/solutions? thanks in advance

Long ping times is normal due to how it operates. But only 5-6mbps? That's pretty slow. Most get averages of 13-18mbps and some get averages around 25.
Try the different modems to see which will be better for your location.

So, its kind of normal to get slower speed while on a call?

It would seem a logical conclusion. But I've never tested it. But I've never had anything not load or go slow enough for me to notice. If I think about it on my next call ill try to test it out.

Ok thanks, The problem here is that I find it way to slow.. lets say I'm downloading a file with no phone call going and I get 600KB/s, during I call I get like 16 to 40KB/s at most... It's like having dial up again... way to slow.. I think something is not right but can't figure out what, since I reverted back to stock wiped everything and also formatted the system after installing stock..

Have you checked your imei or ever lost it?
If not you should really try the different modems.
If this is a recent development you should also call support to see if they have any tower issues in your area.

IMEI still intact, and have never lost it. I will try with different modems thank you! I'm not sure if this is a new issue since I didn't use my internet as I am using it now while on a call before, also I moved from Puerto Rico to the states for a few months, so there are many variables at the same time. But will try with the modems.
Another question, when I odin Stock (not rooted) ROM does everything (incl. modem, kernel, etc) goes back to stock?

Yes, Odin flashing the official firmware will set everything back on stock.

Hello, spent the whole day testing out every single JB modem from your post and none of them solved my problem... did find better speeds with some on them while not on a call. But as soon as I'm on a call the speed drops to about 47kbps, looks like a cap or something because I get constant speed of 47-49 kbps. Sometimes it goes over the cap and works normally but for a few seconds then the speed drops and its not constant anymore until it reaches around 47kbps... This is so frustrating... is there anything else that I can try out??

Flash the LJC firmware package. Third firmware link in my signature. This is for SGH-T999 (d2tmo) only. Unsure about the download cap while talking on the phone. Aren't the two separate? Cell and data, right? Shouldn't be a cap then, but I've never been talking on the phone while downloading a file. I will try it if I think about it tomorrow.
5-6Mbps is not bad. It just depends so much on where you are. My fastest test ever was the other day @ 14.4Mbps. It's not a big city, but it's sizable. It's usually under 10Mbps in that location. And normally less than that everywhere else in the area. There are some areas that put me on Edge. Might as well just turn on airplane mode. Because T-Mobile's Edge... is actually worse than no data connection at all.

Thank you, will try that tomorrow. 5-6mbps is fine for me but that is without call. While on call is like 0.37mbps constant or really bad ups and downs.. is like edge (worst than not having connection at all).. anyways will try and report back. Thanks again

Sorry I couldn't remember this before, but I have a theory that could explain what's going on there.
Voice calls and 2g (GPRS) both share the same frequency spectrum. I remember doing some 3g research in the past and one of the benefits to the introduction of 3g was more overall bandwidth for all, even those left on 2g. At the time, 2g data service was greatly impacted by how much voice traffic was going across the network at any given time.
During peak voice call times, there was less bandwidth for mobile data users because the tech was designed to give priority to the calls. This meant even slower than usual 2g data speeds.
But as people moved to 3g, there were less using 2g for data lessening the impact caused by voice and sms communications.
So what I'm getting at is when you are on a call, that call is going across 2g frequencies, meaning you are connected to 2g. (Though 4g data should still be available to you regardless. But it may have something to do with what you're experiencing.)
Keep in mind that this was 3 or 4 years ago. I'd think that it'd work differently now. But it is possible that they never changed the fact that voice shares its spectrum with 2g. I could be seriously off with all of this, but I still thought I'd mention it since it would make a little sense with the speeds you're seeing.
The thing is, the S3.is capable of using DC-HSPA (dual carrier) which means it can use 2 different signals at once (one from T-Mobile, one from a partner carrier) for greater speeds (HSPA+42). So I don't understand why it won't use this same tech to give you better data speeds while on a call.
I know I've used mobile data while on the phone before, and never felt like the qos was lacking. But I never speed tested it either.
The more I think about it though, the more I'm thinking it's either firmware (see aerowinders post above), hardware, or you're connecting to a tower that either has problems or hasn't been upgraded in a long time. I don't believe that what you're seeing is normal operation.
Of course every bit of this is speculation at this point. Hope no one thinks I wasted their time with it. I thought it may spark some ideas though!

I was looking up some information and ran across this. Figured Id link you to it since it is directly related to your problem.
You can pretty much ignore my above post! LOL

Hello, I still have not called customer service, but I'm going to be back where I din't have any problems next week. I'm going to test it out there. If I don't have problems there, then it's this area the one with problems. Anyways I will let you all know my findings.. Thank you all for the support!
Edit: I just confirmed that it works perfectly fine where it used to worked fine. It must be the new area where I moved recently that has issues. Thank you all for your time and help.
