It's normal, I think it reverts to 3G to save battery.
Those speeds look normal to me for HSPA+

[Q] ATT Infuse on Rogers, need 4g modem/rom

Hi All,
I have an ATT infuse 4G, just arrived last night.
Which modem do I need to get the 3g/4g working on Roger's?
Hopefully something that I can flash with CWM.
I just finished rooting, unlocking and installing CWM recovery.
I now have a "I997RUXKG3" for a baseband, but it is still not getting any data.
Need also a good rom that will work with this setup.
Thanks
Heeter
Bump.
Could really use some advice.
Thanks all.

Try as many out as you can and see what works best!
As long as rogers supports the exact same 3g radio bands as ATT then it should pick it up automatically. If they use different ones then no matter what you do it won't connect to anything other then edge
I'm on rogers and have no problems with any of at&t modems. Just try them all and see which works best for you. I'm currently using UVKJ6. http://forum.xda-developers.com/showthread.php?t=1353209

Hey thanks guys,
I don't have any data (3G, E, H, nothing) So I am gonna try Spider posted.
Will report back in a bit.
Hmmm, you mentioned that all modems should work, maybe there is a setting that I am missing somewhere, 'cause I got no data whatsoever.
BTW, Spidey, Which ROM are you using? And do you have a download link for it?
Thanks

Hey I'm using Darky Rom http://forum.xda-developers.com/showthread.php?t=1354321
After flashing make sure everything is running and then flash InfusionGB-CoreA2 from here http://forum.xda-developers.com/showthread.php?t=1212485
Then flash this tweak Universal Adrenaline Shot v13.zip from here http://forum.xda-developers.com/showthread.php?t=1236779
Before doing any of this try downloading tweakker https://market.android.com/details?id=com.tweakker&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS50d2Vha2tlciJd from market it fixs apn for specific carrier.
Try inputting the Rogers APN look for a search on the forums to find it, it should activate your data.
Thanks for the heads up Spider, Sarius.
Will post back when I check that out.

Hi Guys,
Update:
I flashed that modem that spider provided, and as well I used tweakker.
Now I have a "H+" sign on top,
Is that good?

Glad to hear that all is good. enjoy

I don't know if H+ is good for my area. Don't know if 4G has even made it to my area (Edmonton). I know rogers has been talking about something called LTE in my area.
My Nexus S always says 3G, but it is 3G only, not a 4G device.

Thanks for that explanation, Entropy
Heeter
h+ is the 4g in infuse 4g but its more like fauxG, really its just marketing, the infuse and many other 4g phones work on the 3g network, lte is the true 4th Gen network and the infuse doesn't support it.
the att kernel seems to get faster data because of tcp buffer changes ( if I got that mixed up with something else someone correct me) but the recent custom kernels have the changes and are all built on Rogers sources. the rom shouldn't matter but you need to use the Rogers apn settings. the modems should all work including modems from the sgs4g
weather you see h+ or 4g depends on the rom. it can be changed in the theme. they indicate exactly the same thing.

[Q] ICS Radios.. Which is working best for you?

Hey, I've been reading around the forums and it seems there are 3 main radio's to choose from. I plan on testing them all in depth. It seems results vary from phone to phone especially with the UCLC5 Modem (from the Note). I was wondering if other users would post their results I'm curious to how your phones are handling these modems and what your opinion on them are.
UCLA4 (from the original leak)- I started with this one. I felt like my speeds and signal didn't reflect what my bars indicated. It felt like it said I had more than what I had. I don't recall my speeds but I intend to test this radio more in depth tomorrow.
UCLC5 (modem from the Note)-The note radio is what I have been using since it was posted here. While my radio seems to show less bars I tend to get better signal. 2-4 megs down and 1-2 megs up on HSPA+. I have yet to have noticed anything strange with it.
UCLD2 (from the 2nd leak)-I haven't gotten to test this radio yet since I've had connectivity issues all day.
I think these are all the ICS modems. feel free to post any I missed.
essential I'm trying to get a general idea on the modem with the best speed.
Personally I think the new UCLD2 radio is much improved.
Sent from my SAMSUNG-SGH-I727 using XDA
Newest leak is working the best for me so far. Signal looks weaker in the notification bar but my connection is much more solid than it used to be.
Sent from my SAMSUNG-SGH-I727 using Tapatalk 2
I agree with shepherd the latest leak works the best.
Sent from my SAMSUNG-SGH-I727 using Tapatalk 2
the best thing for everyone to do is to try them all yourself. I think everyone's phone reacts the the modems differently. A modem that kicks ass for me may suck ballz for you. Also once I flash a radio I always use it for a day or two before making any judgements as to whether its an improvement or not.
Edit: forgot to mention that my decive picks up wifi signal better as well. Not sure if that's even a modem thing or something else Sammy changed in the latest ics leak but I sure do like it

Using the UCLD 2 radio released with Sean's Sky ICS 4.2 rom. SO far so good. Not LTE coverage in my area but 4g speeds seem okay.

Ha, and I'm looking at now. I'm assuming many have moved on from Skyrocket (I unfortunately destroyed my HOX), but any update on radios for this device?

Nexus S i9020A Radio question (Speed)

What are the typical speeds that most of you get on ATT with your Nexus S? I ask because Im using a Galaxy Nexus and I know it has a better radio than the S. I get speeds of anywhere from 1.5-3mb down. My niece in the same area is getting around 500k. I heard that I could flash the radio on the Nexus S to the KB3 and it would dramatically increase her speeds. (Apparently there is a cap on the current stock radio??)
I plan on manually updating her device to JB and i figured that while im at it, just flash that radio instead of the stock one. Would this make sense to do or does the stock radio on JB fix the issues that most have with data speeds on att and this device?
Is there a better option I should try for her? A different radio that is better? I would like to keep her as stock as possible as far as ROM goes but I dont have a problem trying radios if it would help the problem. Any advice would be greatly appreciated. thanks!

It's funny, I installed KB3 radio and it's not showing up as HSDPA like it did with 2.3.7. I haven't checked the speeds, Usually the kb3 radio is much faster.

as far as i know , it seems all these radios depends on the area and your operator.
not always newer radios is better than older ones. you better test them all by yourself unless you find someone who lives in the same area and with same phone and even who has tested them all...

TMO radio data sucks.

Hello I've been trying to find a answer to my problem for a while, but can't seem to find any help. So to start off I unlocked my s2 I've flashed 3 different roms and a few different T-Mobile radios, but my data is very poor sometimes it works sometimes not it constantly drops if anyone can offer some advice I'd really appreciate it.
As of now my sgh-i727 is unlocked running on cm10 superlite and the telus radio.
Sry if this has been answered b4 I'm new to the dirrent radios

It probably also depends on your location, too. In the Bay Area and LA, SlimBean w/ a Blaze (LB7) radio has worked just fine for me.
Thanks. I've read over that post a few times. I was using blaze lb7 for a bit but then I started to test others once the data drops and very poor speeds occurred. Also I live in MS I generally have great reception.

I'm lucky to get a 1meg down and up when it actually holds the data signal. I'm actually on straight talk but with the ST tmo sim as my back up phone is the LG g2x. Maybe I didn't flash correctly, but I have tried flashing multiple times and no which radio or rom combo its the result slow speeds and constant drops. Another note my g2x fantastic in my area in ST

baseband help

is there a way to reset the baseband? i wanted to try the "Jedi Mind trick SGSIII Style V2 rom" and flashed the baseband modem update that was in that thread. tried the rom a bit, then restored my previous rom that i was using prior before the jedi mind trick rom. and went to about phone in settings and saw that my "baseband version" was unknown. and i been receiving texts late. is there a way to fix this?

You can find the blaze baseband here, I'm using the newest T989 and signal seems better.
If you lose signal after flashing the radio you want a reboot usually helps or you may have to get the correct APN.

hows that 989d telus modem running for you? I am guessing that the reason the other modem software is working is cause the hardware is similar or same between some of these phones right? is there a way to find out what chip sets are on these phones to get an Idea of what other firmware works on some of these phones? the T989UVMC6 seems to help my charge time a little and dose seem a little faster on download speeds but still nervous about causing any long term problems but there is no signs of overheating or running flaky so I guess it should be fine.
thanks
I have done some preliminary testing with the UVMB1 and UVMC6 radios and have some very definitive results. There's a speedtest.net server where I live so there shouldn't be too much variance here. I have done some other testing with the other radio (the t989d) with mixed results. The t989d radio is very inconsistent where I live.
The UVMB1 is the first three results, and the UVMC6 is the next three. Pretty conclusive to me. I will be on the UVMC6 from here on
I'm also using the UVMC6 and it does seem to give me a stronger signal. I should probably run a test and get some "official" results.
Sent from my SAMSUNG-SGH-T769 using xda premium
been running all day with UVMC6 almost 14 hours and still 64% battery and I used my phone a lot today listening to Pandora radio for almost an hour and 4 or 5 phone calls and played on the web a little. I think I am safe to say it improved battery but I rarely loose much signal in KCMO so I cant say that signal is better but I may have seen more H+ than I normally see. my home has steel siding so I dont see as much H+ when inside but it seems to have been H+ most of the time I checked today.
and again thanks for sharing with the rest of us on this information, it has improved the quality of my phone so many thanks
Welcome, I found it when had my skyrocket and figured I'd try it out. It does seem to make signal stronger and battery. The 989D was ok just didn't hold signal to long
