[Q] 3g everythere but at home????

I have a problem with my Tmobile g2 running 2.2, it is all stock no modifications whatsoever other than handcent and fancy widget.
The problem is I can not connect to 3g or hsdpa network when I am at home. By this I mean the cell tower that provides service when I am at home. I have txt and calling capabilites but I have no data whatsoever. I have to manually switch to 2g or edge to check email or use the browser. I have called tmobile and they keep telling me that the problem is with my phone, however when I am 2 or 3 miles from my house and it goes to any other tower on the planet everything works fine.
I have searched the g2 forum here but could find no answers. I apologize in advance if this has been indeed covered or discussed to death and I have just failed to find it.
I did find the *#*#4636#*#* option and when it is on 2g I can run a ping test and it finds the server just fine, but on 3g it always fails to connect. Again this only occurs of course when I am sitting at home!
Thanks to anyone who can shed some light on this or point me in the right direction because leaving it up to tmobile has proven to be fruitless.

It might also be worth mentioning that i replaced the sim card today as well, this too had no effect on this phenomenon.....

My mom's nexus s has the same problem. Only difference is that when i walk out the door i get 3g. Once i walk back in, I get edge...... I think its might be just tmobile frequencies poor ability to pentrate walls.

Sounds like a problem with the 3G network in your area, or just a weak signal there.

I know its not the signal strength, I always have full bars at home Its something to do with the network....

Full bars on 3G or 2G ? If you have full bars on 3G then it sounds like a network problem.

I have the exact same problem, but my building is probably over 100 years old with 300 coats of lead paint on it. It depends on your building. Signals can bounce off of mirrors for example and other materials. The more material the signal has to go through, the more attenuation happens.

I have a similar problem, my G2 can't maintain a consistent connection, I will go from 4 bars of HSPA+ to 4 bars of Edge to nothing (lost connection to network) and it will jump around wildly between these three states (every few minutes). My wife's MyTouch 4G doesn't do this, my G1 did not do this, our kids (dumb) phones have consistent connections.
I know it's some interaction between my phone and the TMO network, I'd say it was a defective phone except the only place it happens is inside my house.
I wish that TMO offered a microcell.

There is no reception problem, I have had the phone working here for awhile and it always has full bars, like I said I can hop in the car and drive a couple miles and it works just fine. Tmobile finally got back to me today and said they are having their Engineers troubleshoot the tower that provides service when I am home. I hope they get this fixed soon, they said 72 hours.......

It's that anti-cellphonereception chemical they put into paint!!

EC05 Modem & Airave problems?

Anyone with a airave and running the EC05 modem having problems? I use to have great signal in my home with the airave on EB13 modem. Now, on EC05, its hit or miss. I can be 5 feet from the airave and have zero, or one bar. then, sometimes the signal is fine. Data connection isn't the same as it was also(speed has never been high of coarse, but at least it was consistent). Away from the house, signal and data have no issues.
I have un, and replugged airave to no help.
thanks

I should be getting my airave soon... I'll let you know
If it causes me issues at least I'll know to downgrade to EB13 ^_^
Thanks for the heads up!

Did you try dialing *99 and hitting send? you should get a repeating voice that says you are now on airave.
I think sprint's network is just unstable ATM and it could effect airaves as well as PRL updates.
I doubt the last two modems (eb13 & ec05) are to blame.
Have you tested with other phones?
I don't have my airave hooked up, but I've run speed test with two epics and an LG optimus S over 3g (full bar area) and the results are the same. (low to sub 100's and occasionally normal 3g speeds)
Edit: Tested the airave. Full signal, low 100Kb's.
An EVO bud of mine said the network is acting up in his area as well.

Well I've had my airave for a week now but sprint won't activate it... They say that the original airave is incompatible with the Epic 4g and I need to upgrade it to a airave 2... Whatever... Talking to my rep to see what's gonna happen, but it might be a while...
Meanwhile according to sprint I'm in the "excellent" coverage for 4g, 3g, and voice... Doesn't stop my phone from getting -101db 3g and non-existent mythical 4g... Have to try 3-4 times to get a call out... Never get a call in, always goes straight to voice mail... And texts delayed 3-4 hours...

I've had the most current Airave for over 4 months now. I had so many problems with DK28's modem, but it's been working like a champ under EB13 and EC05. There's 2 gripes I've had with the Airave, though:
1. The IP address that it's pulling for internet services is located 90 miles north of where I'm physically at. Sprint said that that's the area they're pulling bandwidth for me and doesn't affect 911 services. After calling about 5 times about this, they finally patched me to the highest level tech manager that explained all of this to me. He said I was one of two people out of thousands to ask about this. It's nothing Sprint nor I can do about it, so I just leave my house to use Google's location services and then it works correctly.
2. The three beeps before making a call is slightly annoying, but I know it's going through the Airave.
Other than that, it works like a champ, I get full bars, good 3G speeds, and I'm very happy with my Sprint service!

Be mindful that it IS going through your internet service provider. That might be the culprit. Check your cable modem/router/or whatever you have it plugged into or call your ISP to see if there's any outages or problems in your area.
There's no one switch solution to your problem I can think of off the top of my head.

Airave works great

Out of curiosity, who here has an airave? My mother got hers yesterday for free for being a loyal customer for 11 years and also because of her horrible coverage in her home. I actually called customer service to see if she was eligible and she was. She used to get 1 to 2 signal bars on her epic 4g touch and now she gets full bars. Her 3g speeds went up 1.5 mbps from .3mbps. She's pretty happy with her airave . I also find out that they are planning to build a sprint tower about 20 minutes away off the highway from where she lives. No reason to leave sprint anyone time soon . Hell if the Tmobile and AT&T merger happens and I hope it doesn't, I'm heading to Sprint.

I don't know about Sprints version but we've used an At&t microcell for over a year with little to no issues. Had to pay $150 for the damn thing but it's been great. They should work similarly.

Have had ours for some time now. Had a couple issues with it, but was always resolved within a timely manner. Without out ours here in the home, we'd see 1 bar if that. Got ours free from the problems that we've had signal wise.

Got an airave v2 from sprint for free since my basement drops calls, works great throughout the entire house, sometimes it doesn't switch properly to the sprint tower when I get out of range outside and drops though, but that's a rarity

I have a new version Airave in my home (got it for free from Sprint cuz of poor signal quality indoors), and it works very well.

That's great that some have it especially for free. One question, does anyone have the GPS blinking green. When I first set it up it stopped blinking green and noticed now that it's blinking. I don't have the airave near a window nor elevated because of how her computer is set up and located. Should I bother connecting the external GPS or just not worry about it. My mother won't use her GPS whatsoever. Thanks.

Gps has to get a signal before airave will recieve data. As well as in highest level of support every call was airave. They work for a while and stop. We had an airave dept, but the calls were in the 100's every hr. We had to take all the overflow airave calls. Hate those things!

I used mine without the extra gps ant. For a few months with mixed results. After a while I noticed the gps light flashed often, so I hooked up the external Gps reciever. Night and day diffrence. The airave never skips a beat, and signal is 100 fold better.

I can't get my airave to work. I have it after the router and the GPS and Mobile lights are still blinking.

love my airvana
if your having issues put it before the router

Airave here. I like it and it works. Was free via sprint rep

I want it after the router. I dont want to use the Airave's routing capabilities since I already have it set up on my linksys router.
I've read that you that you can just plug it in and it should work. I have tried changing the IP, etc. So far nothing.

It needs to be close to a window or attach the GPS antenna to a window. Also first time plug in could take hours to go solid lights.

I want to have it after the router as well, and thats where mine is; however, in a situation like yours where your trying to fix a problem its time to troubleshoot. If you put it before the router and it works then you've identified where the problem lies...

I have 2 of them Since i have a large family on my account that live in 2 different cities they gave me a second one free.I love them while in house i get great download speed and calls are not a issue.
I got it more for the download speed then anything else plus helps with tether

Wait... Your tethering from your phone which gets its signal from the airave which gets its signal from your home Internet connection?
I see two middle men that can be cut out of this equation

I too have crappy signal at home. For those who have gotten unit from Sprint free do you still have to pay the monthly airwave fee? Seems to be unfair since you are using your own internet service provider to hook the airwave to.

By the way to all of you who want it after a Router, I have mine setup after a Router. The steps are easy just gotta port-forward. Google it =)

I did google. I also have the ports forwarded. The mobile and GPS leds are still blinking. It might come down to my charter service is not that great for VOIP (I even have OOMA too). I suspect it's that.
Shoulon, what steps did you do for after router setup?
Thank you.

[Q] Losing all data when toggling 4g? [LTE

Hey everyone!
I was wondering if anyone else is having the problem where if you toggled your 4g to turn it off, you would lose all data entirely? I currently running winner's kang-cm9 and when I try to turn off 4g through the toggle or through the settings, I only get gray signal bars. I'm assuming I should still have 3g after turning off 4g. Is this someone that everyone is experience or is it my phone?

I'm having a similar issue (stock ROM). I notice it every morning when I leave for work. I leave my place and wifi disconnects (lack of signal). Since I don't have LTE outside, it seems like it try's over and over to obtain LTE signal. LTE is spotty in my area, so it will go in and out. However, 3G sometimes fails to connect and I sit there without any signal. It's incredibly frustrating...
Last night I just flashed to Apex ROM/Kernel. This morning I waited for my car to warm up a little bit and by the time i plugged in my phone, it had a 3g connection. I will be continuing to look out for this, but I have been able to replicate the issue in my first paragraph over and over again... something is definitely wrong with the radio on our phone (CDMA).

Oh that happens to me a lot too because I get bad 4g in my area so a lot of times when its switching back and forth I lose data for a while.
The problem I'm having is that I would try to disable LTE/4g to save battery but would end up losing all data (Only calls and text work). On my friends thunderbolt he was able to disable 4g and retain his 3g data. As for me, I lose all data and I have to restart to regain data again when I try to disable 4g data

That's an interesting point. I was wondering how the other LTE VZ phones handled this situation... I think VZ/Google needs to address this in a fix ASAP.

I work in a largish company in Seattle area. We have ~5000 engineers working in the area and I posted the same question since my Verizon GNexus would completely lose all mobile data for hours at a time every 3-4 days. From what the results I got, they said that in our area they are all seeing those problems and they had different devices. I got responses from OG Droid, Droid Charge, GNexus, DroidX2, Thunderbolt.
I've been seriously considering returning my phone since this is clearly a verizon data network issue which is not limited to LTE as their press releases would have you believe.

Well see, i can get data if i toggle airplane mode or cdma to cdma/LTE. it takes me forcing the phone to start looking for 3g instead of LTE.

Very serious issue. Slow reconnects on a toggle that should be unobtrusive between 4g-3g. I suffer from the same issue.
What's worse. The reception in general is terrible. And dropping from 4g to 3g ..the phone either never reestablishes 4g or take.....a. VERY long time. Like, 10-15 minutes. Unbelievable
I'm trying desperately to get google to be aware of this and I'm PRAYYYIINNGG this is a software issue.
P.s this is my third nexus... so I believe this is everyone

Yep... I have two other friends with this issue as well. I just got off the phone with Verizon, and they acknowledged the data connectivity issues... they said an update is in the works and is tentatively sometime Jan/February.... for the record, i'm on 4.0.3 (axi0m rom); not that it should matter ...

What I'm seeing is similar but sounds like it might be slightly different. I have a thread on it here:
http://forum.xda-developers.com/showthread.php?p=21352288
I'm not sure if what I'm describing there is "normal" and the thing they are working on an update to address or if I have a bad radio/phone. Any thoughts?
In my case, it will go: 4G->no_data->4G in the span of about 30 seconds or so. The 4G indicator will still show for a few seconds but I'll get "no connection" kind of messages. Then I get just a solid gray triangle. About 30 seconds later, I see the bars, then the 4G indicator, then the bars turn blue.
Anyone else seeing this? This happened to the phone before this which I swapped due to this problem. What are the chances I got 2 bad ones in a row? Or is it just a similar issue to what you all are describing?

Samsung Galaxy S3 i747 Wi-Fi+Connection ISSUE!!!!

I used my Galaxy S3 a few weeks ago
It is the Rogers i747m Galaxy S3 LTE
The major issues I am having are:
Weak Wi-Fi: the Wi-Fi is weaker than my iPad 3... It disconnects and connects... Even in my living room, next door from my router, my signal is either 1 bar or 0 bar for Wi-Fi, and sometimes it disconnects... My iPad in the same living room gets around 2/3 or 3/3 bars
Weak Cellular Reception: the weak cell signal is also an issue... It is not as weak as dropping my calls, but it is weak and slows down my data speeds...I am using in the wide open in Scarborough in Toronto, there are no high rise buildings.. On 2G, I get full bars... On 3G, I get a bar less than full. On 3.5G (HSPA+), I get 2 bars to half bars. And on 4G LTE, I get 2 bars or even worse no bars and it switches back to 3G or 3.5G HSPA+...
Never had these Wi-Fi and cellular signal issues with my Samsung Captivate and Samsung Wave S8500.....
Anyone can tell my if my phone is defective?
Or is this the phone hardware issue and it widespread with the North American LTE variant of the Galaxy S3?
Thanks.

Good Question, one of which I like to know myself. I'm in the west end (Brampton (for now lol) ), it seems like the signal strength varies even in the same city with only a 3 min drive apart and no tall building in sight lol. I'm talking 1248 kbps to 31743 kbps download.

Not sure about the cellular signal but the WiFi connecting and disconnecting is a known issue(by us, not sure if Samsung) and is being worked on. http://forum.xda-developers.com/showthread.php?t=1790187
Following the instructions in the OP fixes it for me but when I reboot the device, problem is back.

I haven't had any WiFi issues. I don't use it a lot. But I was testing it out tonight and it hasn't disconnected on me at all. I'll keep testing it out
and let you know if I lose WiFi connection. I do recall when I had the S2 i9100, I was losing WiFi connection quite a bit. I wonder if this is a random Samsung device issue? Or could it be an issue with the type of router you have?

If you have this issue, you'll notice right away as it'll connect and disconnect you every 5 seconds or so. I've only noticed it with one WAP and that's one at work, at home and elsewhere it works fine.

I am getting weak Wi-Fi signals around 0-2 bars.. And it disconnects sometimes at random but not as often as 5 seconds though...
Also, the question with the Wi-Fi issue being mass spread might be the International Tegra 3 version
The North American GS3 used the Qualcomm 89xx with has integrated Wi-Fi.. Possibly the North American model use a different antenna design...

I barely talk on my phone but the bars are about the same levels as my iphone 3gs before it was. My wifi I use it in 5ghz, and across my apartment, through 2 walls, im getting near wired speeds.

No issues with wifi here. I at least that I've noticed seems about the same compared to my iPhone and transformer tablet..

for me I am using it on wireless N on the 2.4 ghz band
I have yet to try on a 5 ghz band wireless N

My WiFi feels like it can go 1mb/second..
I do sometimes get roaming messages when I'm at home which confuses the heel out of me

I just accessed the *#0011# and turned the Wi-Fi Power Save to OFF and my S3 Power Save is also OFF
Wi-Fi signal is still VERY WEAK 1-2 bars and sometimes no bars... Did a Speedtest and got around 3Mbits/sec downlink and around 0.2Mbits/sec uplink...
On my laptop, I am getting 19Mbits/sec down and around 8Mbits/sec up.....
I checked the service menu's Wi-fi Information page on my S3 via dialing *#0011# -> MENU softkey -> WiFi
In the Wi-Fi Information, it shows my phone is connected to my router using 802.11b ONLY
What the heck??? ICS Software glitch???

You are getting 1MB/sec down ??!?
Damn how do you do it??
It seems like the North American GS3 with the Qualcomm LTE chip suffers the same Wi-Fi as the International version

But you must have a good Wi-Fi unit.. I will go to the store and exchange my White S3 i737m tomorrow and see if the Wi-Fi problem still persists..

Before you exchange your phone, could it be your router? Did you test your phone out with a different router or in someone else's house? I have no issues with mine. Like I said in my previous post, I had issues with WiFi on my S2. So I'm thinking it's a random Samsung issue with certain routers.

I have 3 different routers at home
1. Standard D-Link Dual-band N router which I bought last year
2. D-Link Xtreme N
3. Linksys Wireless N
| have tried on my Xtreme N and my Linksys on both 2.4ghz and 5.0ghz and the phone just has really low Wi-Fi signal either 0-2 bars of signal and it disconnects and reconnects at random...
The only way for me to get a good signal it basically using my phone 10cm from the router...
I tried the phone at a friend's house, in which case he has a Belkin Wireless N router. Also I tried it on University of Toronto St. George campus' WiFi... Both scenarios results in the same, low WiFi connection signal it seems to fluctuate randomly, Low down/uplink speeds and disconnection and reconnects at random...)
From the phone's service menu for WiFi, it show the phone is only connected to 802.11b (It will NEVER connect to g or n no matter what router I tried to connect to)
Non of these WiFi issues happen to my Samsung Captivate... When I use my Captivate, even when I am in the basement (my router is in the 2nd floor), my Captivate is getting around 50-75% WiFi signal strength on 802.11n
It seems like I did not have time today to exchange my phone due to some University essay due... Will probably exchange it on the weekend.
Will definitely report back on my exchanged model on XDA...

Coming from Rogers Galaxy S II LTE, the LTE connection is weaker on the GSIII. Even when comparing it to the iPad3 at the same location at the same time, iPad connects fine on LTE and the GSIII at times is on 4G.

I did my exchange yesterday..
My WiFi disconnection seemed to have stopped. But the weak signal issue is still present..
I could not pick up public WiFi spots in my University... This is a ludicrous issue... Even in my house, I could barely pick up my own WiFi (if I am literally in the same room or a room next to the router).. My GS3 cannot even pickup any of my neighbors' WiFi. On my iPhone, Docomo Sharp SH-06D and my Samsung Captivate, I could pick up WiFi from neighbors across the street......
Well at least my new unit do not randomly disconnect and reconnect the WiFi now... But the weak signal link is still a MAJOR issue...
Hopefully Samsung will acknowledge the WiFi issue soon....

I have the exact same wifi issues as you. I've called Samsung and their support tech concurred with me that my phone is defective. I verified it with AT&T also when I took the phone to an AT&T corporate store and sat down with a salesperson there with an SGS 3. Connecting to the in store wifi the salesperson had full bars. I had barely one, and it kept reconnecting. I have to wait another couple of weeks before I can do a warranty exchange with At&t because I didn't buy my phone from a corporate store, I got it off of craigs list, and AT&T warranty services won't step in and help until the phone has been on sale for 31 days. So I'm having to wait until then. Meanwhile My data plan started on the 16th of July and I got a warning that I've used 65% of my 4g data up already. I'm sure I'm going to go over and they issued me a 10 dollar credit to take care of that.
It's inconvenient yeah, but at least I'll be taken care of.

AT&T actually gave you credits for data even your phone was from Craigslist?!!
If it was Rogers, they wouldn't even cared.. lmao...
Samsung should make the WiFi issue public... This is NOT AN ISOLATED ISSUE.... It is much more widespread, not just on the ATT/Rogers/Bell/Telus Galaxy S3 i747(m) variants...
The WiFi problem persists on the International i9300 version as well....
