[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!!

[VZW] GN Weak radio bugging me

I don't know whether this is in my mind but since I have upgraded to JB, I seem to be getting weaker signal reception.
I live in a major LTE market and signal is usually pretty good outside on the street. Once I am a few feet from the street, say in a restaurant--even with big plate glass windows--or a house or a backyard, the signal drops to unusable.
This weakness was most graphic this past weekend when I found myself at a backyard BBQ. I couldn't get enough 3G signal to use the internet. Friends (running GB) with the Bionic or Thunderbolt, also on Verizon, standing right next to me were able to get a bar or two and reach the internet.
I'm not holding out hope that a radio release will miraculously fix our signal reception problems.

Wow! same problem here. When I flashed JB 4.1.1 I noticed a big difference in my reception. In rural areas The Galaxy Nexus has horrible reception anyways and We, I say we don't need to be getting weaker signals after flashing this really fast Jelly Bean rom...lol

The Verizon JB roms do not have any new radio's in them so I am not sure why you would be getting a worse signal then before. You should still get the same crappy signal you were getting on ICS.

I had the same issue with my nexus. What I did to correct it was flash other radios that seem to help a lot more.
Here just search for vzw galaxy nexus radio and you should get a search with androidcentral. You will have all ur radios there.

Which radios are you running? FA02?
There's a thread on rootzwiki that has all of the historic radios for Verizon. Reading through it, some people have run a hybrid FA02/FC05 radio setup and say that's pretty good for them.
All I know is that I've got to figure something out. I went to a movie over the weekend and had my GNex in my pocket. I went through 50% battery during the movie because it couldn't find signal... and I wasn't really in a rural area.

I had generally bad service across the board 2G,3G,4G since getting the phone from Verizon. After flashing jellybean and keeping the stock FC04/FC05 radios cell service is pretty similar as expected. I cant really compalin given the area I live in but my old LG Env touch had stronger cell service. The most frustrating part was last week when I was with my friend in the hills of New Jersey where I could not get a single bar of service to even make a phone call and he was getting enough 3G on his iPhone to get on the internet. Rage.

Complete repository of all the radios:
http://goo.im/stock/toro/radios
I flashed FA02 from the command line and everything seemed to go okay but I still see FC04.
Hmmm...
Edit:
I redownloaded FA02 from the link I provided and the flash worked fine. (I had FA02 sitting on my drive from a previous download.)
I'll report back my experiences with the hybrid.

Are you trying an FA02/FC05 hybrid? I was tempted to do a flash-a-thon tomorrow night (busy tonight) and try each radio back to EK01/EK02 to see which seems best.

Nope its worse. I went froma -61dbm signal at home to -75. To make things worse, I lose data in rural areas now and my wifi sucks.

3G vs LTE -- how many bars?

I purchased the Note 2 in hopes of having a little better reception at my desk here at work. If I walk to a window, I get full bars, but my desk is in the middle of the floor, so I get one bar or none. Sadly, the Note 2 didn't change that (I didn't think it would, just hoped it had a better antenna). I'm probably going to return it this afternoon, and switch to Verizon next month when it arrives there. My coworker's S3 on Verizon has full bars, and he sits 3 feet away from me, but he also has 4G on his (can't figure out how to turn it off to test his 3G only).
I like Sprint, and if I knew LTE would change these reception woes, I'd just tough it out until it hits Memphis. Has anyone had a problem getting 3G, but then saw their reception increase with LTE? The older 4G would not reach my desk with my 3D, so I'm skeptical, but never hurts to ask.

don't change carriers just because your desk is in a bad spot. I can guarantee you there are places in your building, or even other buildings where the roles will be reversed.you will be the one with signal and him with nothing

Unfortunately, this is where I spend 8 hours a day, and there's no chance of me moving to a different part of the floor. When I'm at home, I use Wifi, so it's not an issue, but here at work, my phone is basically useless because of Sprint's weak signal. I can move to Verizon with no penalties, and with my corporate discount the rate is the same (unlimited data goes away, but I've never gone over 2GB a month), it's just a bunch of trouble I'd rather not go through if Sprint's LTE is strong.

[Q] Why do I have terrible phone signal but constant 3G/4G?

I work in downtown Houston and, while I am always connected to either 3G or 4G, I consistently have terrible phone signal. It'll only ever range from zero to 3 bars and I don't even think I've seen a full signal since I've owned this phone. Now, this isn't too much of a deal as I can always text and make calls (although it takes a while to connect sometimes.), but I'm left wondering if this is a cell tower issue or if something may have updated incorrectly. I'm rooted and unlocked and have only ever flashed the last 6 or so Lifeless ROM updates, so I don't really think I could have messed it up myself, but I find it hard to believe that downtown Houston would have such bad phone signal. Any insight?

I work in Downtown Denver and have a very similar problem downtown, but not out in the suburbs. My Sprint store has given me a couple of explanations.
1) The buildings block the signal. There are areas of downtown, particularly by the tallest buildings, where occasionally I will drop my cell signal completely
2) In a higher concentration area signal is reduced due to more people using that signal (I don't understand how this one affects signal strength, but that's what I was told)
How is your signal outside of the downtown area? Did you update Profile and PRL after flashing? Ever dropped the phone?

Well, I live about 14 miles west of downtown, and even there, I don't get full strength signal. As I said, I don't ever remember seeing more than 3 bars of signal. I update the PRL and Profile after every flash, and just today I dialled ##72786# to see if the hands free activation would do anything but no luck. I've also encountered moments where I'll be at home (again, I normally have data coverage and a few signal bars) and suddenly, I'll get an alert notifying me that I'm roaming.

That happened to me the other day. I was at work and I got roaming pop up. Really weird since that never happened before and because my 4G is so strong. 36168kbps Down and 6304kbps up.

This has been an issue on every LG Sprint phone with Android I have used. I am not sure what causes it but the bars on the screen never show full strength. That doesn't mean it isn't working though. I have heard it is just how LG worked the rom to show signal.

Let me first start off by saying this is the furthest from the truth. If it shows a weak signal its because this phone has a weak signal.
This is my 3rd day with this phone and as much as I raved about it on a couple of threads, weak signal is definitely one of the negatives.

How can it have weak signal if when I get this I am getting 36168kbps Down and 6304kbps up?

Dude the LTE radio has nothing to do with the phone signal. Two separate radios.

This phone just has weak radios. Now the question is, is it a software or hardware issue? my bet is software but then again I'm not an engineer
Edit
Funny thing is open signal maps gives me an 85dbm reading yet in settings it shows 94 dbm

I just discovered if you switch the network setting from LTE/CDMA to CDMA my signal bar gets full.

I don't have an issue with 3g I get great 3g signal my issue is with lte. Lte has bed in my area since late August early September and I've had the s3 evo lte and the iPhone none of them have had an issue picking up or holding lte the lgog does.and I think it all boils down to the phone not recognizing the correct signal and thinking its weaker than it truly is. In my house and through my town I would never drop lte On the others this phone barely holds it. I've been 100 yards from a cell tower and the phone won't go below 84dbm when I know the signal strength is stronger

I installed the Network Signal Info app on several phones in my store and the LGOG registered about 9db worse consistently compared to the SGS3 or Evo LTE

About the same thing I've seen with this phone I'm hoping its a quick fix for lg with the next update. I was really hoping that zv9 would come with a new radio

Getting Verizon to address signal issues?

Has anyone had luck getting signal issues addressed with Verizon?
My signal has gone to crap - I thought it was my new One M7, but my wife's S4 is exhibiting the same behavior...can't help but think something is wrong, as I used to get a solid 4G signal at home a few months ago on my ReZound.
I live just off a major state highway, I am in town, and right in the middle of the 4G coverage for Verizon (there's 6 towers within 4 miles of my house, and 17 antennas - according to antennasearch.com). The local Verizon tech pulled their map and said I should be getting full signal at my house.
Despite all this, when I get within a mile from my house coming in fr the East on the state hwy, I drop to 1 bar of 3G and lose all data. At home, I switch between these signals:
(rare) 4G RSRP -120 to -123 dBm
3G (eHRPD) -110 to -118 dBm
1 1xRTT -97 dBm
If I go another half mile west in town (which is flat land), I am back to sub -100 signal on 4G. Any way to get someone to actually investigate and do something about it?
Thanks...

Call tech support and demand that they send a tech to investigate. I have to do it constantly. They tell me every time I call everything is fine on their end and a few days later it gets better all of a sudden. It's like they don't want you to know they have an issue.

You on the latest radios? I noticed when I updated to the latest radios my signal improved. Still would call tech support and have them check what's going on. Don't take we have no issues as you live in the area and they don't. So they should take your word for it. If you know others in your area have them call to so they have to take it seriously.

Man, I have tried newest radios, older radios, combinations of different setups with different ROMs (Sense and AOSP based), flashed RUU and did factory resets, back to stock rooted with new and old radios, and even a new SIM card...now back to 100% stock and fully updated - getting ready to see if they will trade out my hardware in case mine is bad.
One odd thing - when I first got the phone, the Best Buy tech couldn't get the SIM to activate, and had to call Verizon. When I swapped my SIM out two weeks ago at the local Verizon corporate store, they couldn't get the new SIM to activate and had to go to the back and do it from the computer...which is what makes me wonder if my hardware is bad.
Have had Verizon here (same house) for 8 years...very rarely had a dropped call in that time up until about 2 months ago (when I got my One M7). I drop about 1 out of every 3 calls now, and the other two get garbled sometime during the call - I hear "you're breaking up" at least once per call.

Your wife has a totally different phone and she is having issues as well so she has hardware issues too?

Her Samsungs always had worse reception than my ReZound (why she likes them, I have no idea) - but I chalked it up to bad reception on the device line.
I never looked into her signal strength until I was comparing my One to hers, which is when I noticed her signal is also bad (mine is worse at times). That's what made me wonder if it was something Verizon should look into in the area.
The hardware thought on my end is due to the fact that I can't find a combination of radio/ROM/RUU that will improve my signal at home and the fact that both SIMs had an issue activating in the phone. Grasping at straws on the hardware thing really.
May reactivate my ReZound tomorrow to see if the signal has just gone to crap here or if it's my phone.

I had signal issues at one point and the problem was because the SIM couldn't seat all the way because of a tiny piece of plastic still attached to the back side of the SIM. It made just a tiny little bump that made it so the tray wouldn't slide all the way in. Since then though the problem in my area has been Verizon. Every time I've called to tell them the coverage here has been crap they tell me the same old it isn't their fault junk. Keep hounding them and they will send a tech even if they tell you otherwise. Like I mentioned before. They almost never admit to an issue with a tower. The only time I have heard of them admitting it was when it was bad enough that they received several reports.

Update:
I reactivated my ReZound yesterday morning to see if my recollection of signal was off or if things are worse on the network near my house.
I monitored it heavily yesterday, last night, and again this morning, and at home the ReZound keeps a 4G signal ranging from -110 to -120.
I did a side-by-side comparison with the wife's Samsung, and while the One mirrors the Samsung (when one drops to 3G or 1X, the other is doing the same), the ReZound held the 4G signal. I watched the Samsung go from poor 3G to 1X - ReZound held 4G.
Also, the dreaded 1 mile dead zone around my house - on my One, Slacker quits playing about a mile from home, says it has lost connection to the server, even though I am on a decent 3G signal. Twice yesterday (coming and going), the ReZound held 4G through the zone and Slacker never skipped a beat.
Conclusion - either something is wrong with the One (and possibly the Samsung?), or the One simply can't contend with a weak signal as well as the ReZound.

If a rep said you should have full bars they might not have the antenna aligned right. I remember years ago someone on one of the sites talked about the same problem he was suppose to have full signal but want and Verizon sent someone out to check alignment and found the person who installed it didn't have it aligned right. After he rest the antenna the guy had full bars. I'd bet this happens quite often and maybe have the two that told you to have someone sent out to see if the antennas are setup right

With newer phones, they may be dropping the 4G and 3G signal because it is below the preset threshold in the firmware. -110 to -120 is horrible. You should be getting higher than that, like -90 and up.
Edit: if Verizon is saying you should be getting full bars, your signal should be above -78dBm. (Signal is measured in negatives, so "above" -78 is 77, 76, etc). If you read any documentation on signal strengths, you will see anything below -105 is so horrible of a signal, most data, sms, and calls are frequently dropped. With you claiming with the Rezound having not experiencing this, it is highly likely what the above poster is saying is true: antenna alignment is messed up. Even a fraction of a degree will mess with signal quality.
