Hi guys.
I don't know if its my phone or if this is the way the phone is meant to be, I have an extremely weak wifi signal. I am literally right next door to my router and I only get 3/4 bars for signal strength. As soon as I go up to the second floor, I get nothing at all unless I'm directly above my router. This is extremely frustrating at the moment. I decided to lurk around the forum to see if installing a custom rom would help and I ended up installing Jedi Invasion 2; it did not help at all.
It's just so frustrating that I have to use my mobile internet when I'm in bed instead of using my home internet. I don't understand this at all. Why is it so weak? Does anyone else have this problem?
Thank you.
Im with you on this......im staying tuned..

Have you tried updating your modem to the latest version that was just released?
My modem is perfectly fine. I just dont understand how my old crappy blackberry had a better and stronger connection than my s3.

I found the Wi-Fi performance increased a fair bit when I upgraded to 4.1.1. I can go a fair ways in my house before dropping bars. Wish I had run WiFi Analyzer before the upgrade so that I could actually compare RSSI.
Depends on the router freq. 2.4ghz and 5ghz. 5ghz can cause crappy WiFi strength issues. Change the settings around to 2.4 only and see what happens.

My router does not support dual band. Like I said earlier, my blackberry has a stable connection while my s3 struggles.

I had the same problem in 4.0.4 ICS but now on 4.1 JB it is working perfect. Before on ICS I had like 3-4 bars when I was 2ft away from the router. Now on JB I have full 5 stable bars no less with higher distance.

The modem he is talking about is a radio for the phone. Not the modem that connects you to the internet through your ISP.
Oh. Im still relatively new to this device so I never knew. How do I update the modem?

Well first thing your going to have to do is root the phone before you can update your modem.

Att is rolling out jelly bean now through kies. Id just do that before you hit the modding route. Jelly Bean will update you too there latest and greatest modem and boot loader updates. Then root it and never look back

So I went ahead and installed the latest modem. It made my signal even worst somehow. How do I restore back to the one I had?

Dumb question but have you checked your network settings. If you backed up your stock rom restore it and see if you get 4g again

Just make sure you follow all THREE steps. People have a habit of completing one step of injecting the IMEI and thinking that's all you need to do.

Trust me bro, you can. Just follow through slowly and you'll fine. To make life easier, go back to Touch Wiz and just take it line by line.
You were capable of rooting and flashing, you can pull this off.

Also lost 4G
After rooting and flashing Dev-3.22.1540.1-Stock-Rooted-DE-ODEX.zip ROM I lost 4G. The best I could manage is 3G. Now I flashed latest Viper ROM, but still no 4G.
Any idea why?
(I checked APN, it's something else).

I'm having the same issue. When I go back to my orginial rooted backed up CWM KK 4.4.2 3G works perfect. Flashed a new ROM APN, IME and even checked *#*#info#*#* all are good. I just can't get 3G.
Any ideas?
This is rom issues/kernel most likely try to Odin please check your provider as well
Some roms/kernels break the service you may use unfortunately
For the past few days my data has been real slow well when downloading it starts off at good speeds but after a few minutes it slows down big time and for it to go back to normal i have to switch off my data then on and repeat that process any ideas what it could be or how to fix it cled tmobile support they were no help thx
Give a little more info
Are you rooted?
If so, are you running stock?
Custom rom name if any
Baseband version?
Yes im rooted running wicked v10 tmobile baseband version t999uvlh2

Well, how much data have you used? You could be getting throttled especially if you've used lots of data in short amount of time.

T999UVLH2 is your baseband version. Then i would try flashing the T999UVDLJC baseband and test it out.
There is a new mdm5 baseband out. Im sure you cant search and find it here.
I flashed wicked v10 on my friends tmo s3, were getting slow speeds as well. Gonna try a different radio

I have the same problem in a certain part of Seattle where my hspa+ speed is around 4 - 10 kilobytes per second download..
Guess to many people using it
I don't think it's the rom itself. Try a different modem and report the findings. I'm on Wicked v10 in souther cali with latest modem and I'm getting great speeds. Can it be on tmobile end updating/refarming towers?

Yeah i dnt know wat is wrong with it its been a few days now and same thing when i run a speedtest i get geood speeds but as far as downloading anything it starts good then goes down to like 650b and downloads always fail thx for the help tho

Wow I was just trying to find out if others are having the same problem and Bam I see this. My download speeds start high then go slow. Hopefully it's the modem
I noticed it didn't start until I used the new T999UVDMD5
Edit: nope tried other modems and problem is still there

Do you get different results during different times of day? Could be network traffic. Or if they're doing work on any towers it could also cause problems like that.

Indeed tmobile is upgrading their hardware and adding towers now that their LTE is spreading to more cities. Also since the merger didn't go through with At&t they are upgrading to compete in general.

Call support to see if they are working on the network in your area.
If not, try the other modems in my baseband thread.

Ive been running Infamous Rom for a while & a few days ago, my 4g startef acting up. I tried a different rom but no real change. I went back to Sonic FreeGS3 which had previou as ly ran fine but my 4g still sucks. Most apps are ok but Play Store & my web browsers refuse to load 9/10 times.

Still got my imei, flashed a different modem late last night & so far so good. I had the same problem with my wifes phone after I rom'ed hers but I restored it & it was fine after. I guess T Mobile changed something and I was on the wrong frequency to get a signal.

Same thing has been happening to me. I'm in the upper Manhattan area and getting really poor 4g in my apt, like 1 or 2 bars, and dropping to 2g. I started noticing it yesterday. I'm calling T-Mobile tomorrow to see what's up.

Sounds to me like they may be doing maintenance or upgrades.
Call T-Mobile though and they should be able to tell you for sure.

Ive noticed since I moved offices, that in my office building I get absolutely no service whatsoever. And there is no wifi password available to use wifi via my phone. So today as I was leaving work and finally got service again, I had 12 missed calls, 5 texts, and 3 voicemails. Is there a better modem to flash that can help? Thanks!
Not exactly. Different locations have different best modems. You just have to try them and see.

Do you think you could message me about what modem/radio might work better once that forum is sorted out? It really sucks not being able to use my phone at work for 8 hours. Thanks
I may not be able to unfortunately. I messed around a little before and got nowhere. May have to start a new map.
Have you checked T-Mobiles coverage map yet? There just may not be a signal there in the first place.

I never had a problem with my Blaze there. Even at home with the S3 I get maybe 2 bars. Which leads me to believe its the modem. On my Blaze I had an updated modem that made data very fast.
Can I use UVLI6 which is a 4.1.1 modem on a 4.1.2 rom I am currently using? Would that be compatible? i cant remember which way compatibility goes :/
Any modem, any rom, any build. Only make sure you use the right models modems, which it sounds like you are

You can use any modem version as long as it's specifically for your phone.

This is just strange... in roughly a year of doing this I think you're the first to report that happening. 4.0.4 and 4.1.1 modems have always worked on 4.1.2, and any other combo has worked as well. There are people who still use the LH2 (ics) modem because it still performs better than any other for them.
I think you may have been seeing it function normally though. When idle, its supposed to drop to UMTS to save power and bandwidth. If you check while a transfer is occurring you will see it change to HSPAP.

Has anyone else found another modem that they now use that gives them better signal/data speeds for their Tmobile T999? My work building is a complete dead zone for Tmobile, so I am hoping flashing another modem works. Otherwise, im not sure what else I can do.
I have to refer you to my initial response here. A modem that gives better speed and signal for me, might be one of the worst for you.
Just something to consider, you probably could test 2-3 different ones each day at work. Maybe more. If your main issue is signal, then flash, check service, if none then flash another right away. I could probably flash 5 different ones on a 15 min break if I was only looking for improved signal. Might be a better way than waiting for someone to tell you what worked for them, then testing only that the next day. Its your phone and your time though, so its your call. Just tryin to help
