[Q] Frustratingly Slow Data Issue - Galaxy S III Q&A, Help & Troubleshooting

Hello, I was hoping if I could get some help on slow data speed issue. I'm currently in Baltimore, Maryland area on AT&T unlimited LTE plan using "pta" APN setting. I see people reporting averaging around 5~8mbps on hspa+ but I'm not able to go above 2mbps. Most of the time it's 1~1.5mbps and it's so frustrating.
I'm pretty sure I have the right settings, but I'm not sure why I get such a crappy data speed? Any ideas? Any advice will be greatly appreciated, thank you!

Have you tried switching modems?

I haven't tried that yet and there were so many of them I wasn't sure which to choose :/ switching modem is the only option I have to increase data speed?

You CAN try switching modems.. but the most reliable thing you should do is to contact your service op for this

It depends, have you rooted?
I would do as above suggested by contacting you service provider.
However modem switch is quite easy. Not sure exactly what modem would work best in your area. But it cannot hurt to try and if it does not work out switch back...

Haven't rooted yet but I guess I'll give it a go.
I remember there was a thread with all the S3 modem listed... Now I can't seem to find it, anyone know?

ty, it works
Just wondering, is there another setting other than that? It does work but I'm getting ~2-4mbps, but before I flashed from KG3 to KG5, I was getting up to 7mpbs. I'm in the same area as I was before, and also tested during the same time of day.
Try flashing an older modem ... the one with which you were getting high speeds.

I have pre-rooted and deodexed rom found here (http://forum.xda-developers.com/showthread.php?t=1935570) installed on my UK (bought from t-mobile) S3 LTE and tethering works a treat.
Ive got quite abit of different mods on mine practically like a new rom and tether also works great obviosly if we have that option then it should work and if it doesnt its either a software bug , network, or faulty phon. Or even the other device thats connecting to it.

Contact your service provider | by calling 150, and perhaps option 4 for technical support, as EE may have this option disabled for you by default, I have yet to check if mine works because i just ordered this as an upgrade (Everythings Unlimited!) for only £41 a month LOL
i am tethering right now and i am shocked as it is very fast even tho i am near the ocean and bushland./Lake but i am on 3G , as there is no 4g coverage out here yet. You would spin out if you knew where i was . Its 12am I am in front of a MASSIVE lake in a tent near the bush and just to see if i could, i hooked up my mini netbook up to my i9305 and all i can say is AWESOME i have now been on a stable connection for 1 hr. who needs a hardwire connection when you have a S3
Hehe i better get off now and get back to the nature haha. cya

[Q] AT&T Modem for N4 Converted

Does anyone know if there is an AT&T modem flashable zip for the N4 converted LGOG? I'm using .33 modem now, but I'd like to have the AT&T modem for better LTE speeds.
Also, is there development out there for an AT&T modem with working GPS? I don't mind having .33 and AT&T modems both on my SD card and flash whichever one I need based on GPS/LTE, but it would be nice to have only the AT&T modem so I don't have to switch back and forth.
Check you're pm

This is interesting - I'm running the .33 modem and find that me GPS works the best with this modem and with LTE I've hit download speeds of 53MB.
I'd be interested to have the AT&T modem as well just to see if there is performance difference between the two - could I get it as well?

hmmm...man, you may just want to start from scratch and download the ROM of your choice and wipe/format /system and all the usual stuff.
THat would be the first place I would start with an issue like this.
Just noticed with the ATT modem I can choose the network mode (gsm,etc) but the other ones don't give the option and also when searching for network ATT modem shows two possible ATT connections, others show one.

thanks for the reply. thats the same one that im using at the moment but the back of my phone keeps heating up when im using mobile data. im wondering is there a different modem that would work on mobilicity?
Heat is normal for me under data usage. Every phone does that.
For the modems, just keep trying different ones until you find the one that works best for you. There is no 100% guaranteed to work modem for everyone. Good luck

Im with wind and use the telus modem which gets wicked speed. When using a cm based rom yhere is no need to tweak but if using a TW based rom do this trick, go into dial pad and input *#2263# then chose wcdma then pick 850 band, exit out and then go back in again via *#2263# and pick auto, wait a few secs and run a speed test. Mine hits around 2500 to 3000 which kill my hd2 at 1600 to 2000

Note 2 WIFI Issues on ALL roms

Trying to figure out why my wife's note 2 running JB v16 has one bar of WIFI sitting right next to my vzw S3 with full bars of WIFI signal.
This has been an issue on every note 2 rom I have flashed.
Does anyone have any possible Idea of what the heck is going on?
Thanks in advance.

Check your broadband. This will tell you what your radio's are set to. If you have updated roms, but never updated radios, that may be your problem.
