4g problems - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

Tried posting on the aokp forum no one helped.. soo I have a data plan 300 mb I'm on the cm10 kernel and soon as I flashed the rom noticed the 4g is like 500 KB speed and i remember 4g lte isnt that slow it doesnt even use lte even though I chose the APN settings to the att lte
Should I flash a new radio or what?
-thanks

Did you reboot after you selected the APN? Can always try reflashing your kernel. What ROM did you come from and what one are you on now?

Came from stock did full. Wipe and everything

EDIT: ON AOKP I flashed aokp and flashed a cm10 kernel even before the kernel flash I had data problems

It shows 4g but isn't giving you 4g speed?
How fast was it when you were in stock.
On cm10, 4g is lte

Your not getting throttled are you? Your speeds were fine when you were on stock? Are you sure the APN is correct?

On stock I was like 3 or 4 mb sometimes 5

I mean did you go over your data limit in your billing period? I'm on unlimited data. But if I go over 5G I get throttled. Meaning the data speed I'd knocked wayyyy down until the new billing period. I'm not really sure if u get throttled on your plan. It may be just the unlimited plans so I may be wrong in your case

From what I've seen with my phone is that I get slower speeds when i have the battery saver on - At least since i started to flash roms. I was getting terrible speeds when i would test. I turned off the battery saver and things went break to normal.

FB27 modem

How does it perform? Can it used with GB?
Its a radio my friend. I do not believe like all the other leaks its dependent on a OS. Also like everything else the best thing to do is try it out yourself... Opinion will vary...
It works great for me. Radios can be flashed on any rom. They are not dependent on each other.

Yes modems do not matter on rom kernel theme odex deodexed and fb27 is great for me but you will have to try it out and see all phones react different
I haven't noticed any improvement with it over older modems but it seems to have improved data speeds for some others.

Im running a GB ROM and using the FB 27 modem, no issues, no complaints.
Running on blazer 4.0 with fb27 modem and I went from .03 mbps to 1mbps. So big improvement for me on 3g.

FB27 modem is definitely the best so far for me. 2.3mbps DL on 3G at my house.
This is the first modem I've tested that i got a significant increase on 3g. Went from less than 400 kbs to 1mbs. I'm in md using unnamed rom

Most of these modem test seem to have been taken late. If they stay high after say 9 am eastern these are great results.

Wow you're pretty lucky, I've never experienced half that speed on Sprint. Unless I'm traveling through a 4G area (not very often)
I went from 200kbps at work to almost 500 still kinda sucks but enough for pandora

[Q] Why is my AT&T LTE increadibly slow?

Status bar says I have 4G LTE but 5mbs? I've seen other people well beyond 30mbs.. 5mbs seems more like HSPA+..

Probably just the area. My HSpa+ speeds are so erratic lately.. sometimes I only get like 50kb per sec its horrible.. att needs to step it up and upgrade the network.
Sent from my SGH-I747 using xda premium
Some ROMs take away 4g.. I don't know about the ROM you're currently on, but mine has said I have 4G when I was really limited to 3G. I know this isn't much help, but I've had similar encounters and it was the ROM I was running.

It says LTE:14.
Just wondering for those with good speeds, which baseband are you running? I'm on I747UCLH9. And I hadn't had high download speeds since I flashed it.

Problems with 3g data

Anyone else have the sprint version of this phone and have problems with 3g data at times. For example it sometimes says I have full bars but Facebook will say that I don't have a connection at all. I'm wondering if its the phone or does sprint just have crappy 3g in LA? What do you guys think?

OK so switch to just CDMA helped a bit but its still happening. I think it may be a soft wear issue. I hope that's just it.

That upload speeds are faster because they're not as heavily impacted by users as download speeds are. In other words, your local site is over capacity and its resulting in slower speeds for everyone. Once sprint upgrades your site, it'll be epic.

See the same thing, pretty confused.
Speed tests show 3Mbps down and 1+-Mbps Up
but it usually sticks with h+ anytime i do something
Well I was in a major city yesterday and they have 4g but it was jumpin when I was sitting still in the middle of town
Sent from my SGH-I927 using xda app-developers app
With the newer ROMs the phone knows when there isn't a need for 4G or H+. It drops down to 3G to save data and battery. As soon as there is a need for higher data speeds the phone automatically adjusts to meet the demand. Trust me you are getting your 4G when you need it.

3G issues

I'm having a lot of issues with my 3g. Don't think it's Rom or kernel related though. My 3g just drops and takes forever to connect and I even did the soft reset with 611 today on tw and nothing.
Any body have any ideas? Lol

Join the crowd, I think it's Sprint, here in Louisiana, they say they've finished 3g upgrades, I can't tell a difference at all. Some spots seem to be better than others. Seems at night I get better speeds. Mine does the same as what your describing, AOSP or TW has nothing to do with it for me. Luckily I can connect to Verizon's 4g most of the time.

I'm roaming on their network, because where I live, still no Sprint 4g. I just turned LTE on one day, and voila, 4g.

Have you tried Reprovisioning your data ? You can call Sprint, or you can do it yourself. Dial ##72786# in the dialpad. The Device will reboot once, or twice while it is setting up. Just let it do it's thing.

Try a different Rom. Just to rule out the possibility. If that doesn't correct it, I would ODIN back to Stock. See if that resolves the issue.
