Hello,
I have a L900 running on ST and live in a pretty rural area. At times 3G locks on instantly, while at other times it takes several min or much longer to lock in. Is there an earlier modem that would work better in rural areas?
Thanks in advance for any assistance.

I have my T989 on the Bell Mobile network in Canada. I've been having problems with the data network lagging when I investigate it seems like it is constantly switching from HSPA to HSDPA and HSPAP. When I first setup I was getting speeds of around 10-15mbps. Lately I'm ranging from 15kbps to 3mbps and this is all from the same areas I typically got higer speeds. While researching I found out I could set my preference to WCDMA only which is appropriate as Bell does not have a GSM network, just CDMA, HSPA and LTE (no LTE in my area).
Does anyone have any idea what maybe causing these slow speeds? I've tried several different modems all with the same results.
Update: When I go to stock Telus rom I get the fast speeds back but only for the first five minutes then it goes back to slow.
you can try puting a telus radioin after flashing a rom. You can find one here: http://forum.xda-developers.com/showthread.php?t=1895400&highlight=telus+radio
Thanks for the reply, the problem ended up being a tower in my area, Bell is apparently going to fix it but it's been like this for at least a week already so we will see. There is another one within range that would solve all my problems but I get put on this one every time as it's the closest....sometimes I wish it was possible to at least request a different tower and not have to rely on the network to tell the phone which one to use.
I live in Dallas tax and according to the coverage map lte is all over. When my preferred network settings are set to lte/ cdma it never connects to lte goes to 3g for a few minutes then disxonnexts. Switch my preferred network settings to cdma and 3g is always connected. Could this be a cyanogen issue or do most people deal with this? Any help would be appreciated.
Thanks
Sprint's marketing department figured it'd be better to show LTE coverage of completion. Unfortunately, your area is probably not covered yet, but will be once the city is completely upgraded.
So basically I need to leave it in CDMA preferred network mode to keep it connected?

LTE coverage would be a Sprint problem - the random disconnects are timeouts through eHRPD via Cyanogenmod RIL issues. It wont timeout on you on other ROMs, but if you place it onto CDMA only, you'll be fine.
Until Cyanogenmod fixes the problem, the random LoS (Loss of Service) issues will continue.
If you download and use Sensorly, it shows actual coverage, where actual users have picked up LTE coverage.
Anybody know of good ROMs that don't have this issue? My friend said aokp is good but he's on a different carrier, any thoughts?
Thanks
I was using AOKP and was having this same issue... assuming it's because they get a lot of their code from the CM repos.
I ended up trying out a few different TW ROMs and my signal strength was amazing with any of them. Currently I'm using FreeGS3 ( http://forum.xda-developers.com/showthread.php?t=1748818 ) and have no real issues.
The only thing that bugged me about the TW ROMs is some of the default apps like Email/Exchange, but I just replaced those with the APKs from AOKP and everything is fine.
If the signal issue gets fixed in CM/AOKP I would be more than willing to jump back, but the massive difference in signal strength is too much for me to not use a TW ROM.

All AOSP roms are based off CM10 github, so they're all going to have the issue. AOKP is a little dated now 11/10 build doesn't have LoS, but it doesn't connected to Ehrpd either. The issue is, once LTE connection is established, and you move outside an LTE area, you go LoS for a bit (some say 20 seconds, others say 5 minutes). But it wont lose signal until LTE is dropped.
EDIT: the cm10 timeouts were after the LJ7 blobs were implemented, which I believe were 11/11 and after.
This is also happening on stock jb.

thanks for the info, going to flash the tm rom when I get home.
Im in Dallas as well and its still being built out.
I get 3G at home, closer to down town. I get stable and steady 4G LTE at work, near Abrams and NorthWest HWY. In fact at my office on the 4th floor im on 4G LTE all day, ride the elevator down and by the time i get to my truck in the parking lot back to 3G. Drive a minute down the road and it might go back to 4GLTE again.
Luckily for me at my office on the 4th floor i get 4G LTE strong enough it holds the signal and isnt constantly switching.
The odd thing is a couple times a week my phone will switch to 4G LTE at my residence but when this happens i get no data on my device. I have to wait for it to go back to 3G to get data back. I think its a tower issue.
I'm having the same experience. LTE usuallys drops quickly. I get it in my apt and it is pretty fast. I live in Richardson. I experience LOS when I try to go from 4g to 3g. It drops the call everytime.
Well damn, hopefully they hurry and build out the network around dallas

I think thats the sentiments of everybody on Sprint with an LTE device.. No matter where they are..

I'm visiting the family in SE Kansas for the holidays and have yet to get ANY signal on my Epic 4G Touching running Re-Calked FI27. 3G signal is decent back home in Austin but I get the "no signal" icon here pretty much all the time.
I checked Sprint's coverage map for the area and we're definitely off-network. FWIW, my wife has a Sprint iPhone 4S that gets decent signal around these parts, though it usually says she's on the "Extended" network.
What gives? Is this a modem issue? (I've flashed through a few that have done well back in Austin) Is it a limitation of the device not being able to connect to the wireless band supported by the towers around here? I can't even get signal to do a PRL update, but I'm not sure it would matter. Would the Roam Control app be worth buying?
I'm stuck. Thanks for reading.
I think I might've "fixed" it by toggling the roaming options off and then back on. I now have the bar icon w/ the triangle above it, although the signal is pretty low. I'd still like to discuss this problem further, though.

I don't use Roam Control. I uploaded a Verizon PRL to the phone. Check this thread for what you need.

I have the 00002 PRL on my phone. You can do a PRL update to return back to Sprint whenever you get back home.
That's all I know. Hope it helps...
How's the 00002 prl working for you?
I've had my Note 2 for a little over a month now.. this phone is amazing. Period. I came from Galaxy Fascinate, its like I switched my Cavalier for Jaguar CX-6!!
I'm with Telus in Newfoundland.. St. John's to be exact. Off course, like most of you here, I didn't have the phone an hour and I was flashing roms, kernels, and modems. I've tried them all, and like the CleanROM 4.5 w/ Perseus Kernel and MA3 modem. This is an awsome combo, wicked battery life (3+ days, easy), and everything runs fast an smooth.
The only minor issue I'm having is the LTE service. Telus say that LTE is available here, and should work everywhere. It does work, but only when I'm outside.
When I'm in my house, I get H+, never LTE. I can take my phone and hold it out the window and it will get LTE. This has been the case with all Roms/kernels/modems; stock included.
So, is this a bottleneck with LTE, is the single that weak it can't go through a house?. Not a brick house, your plane jane wood. Is it a limitation of the hardware?
When I do a speedtest when inside, I avg. 4-7mbps down, 2-5mbps up. If I go outside, test again from the same server I get 17+mbps up/down.
Anyone have any suggestions?? if in the same area as I, what has your experience been?, maybe their is something I might be missing.. a settings I can try etc...
Thx,

Posted in the wrong section really.......
But, to answer your question, LTE and the other 4g signals tend to be fall off faster, so you may be in a low zone or at the outer reaches of the 4G signal where the signal is just weaker, I have had the same issue and bought a signal booster for the house and that solved the not getting 4G in the house.......
Good luck,

This is an update to this thread. I am on t-mobile's service on an i747 in a refarmed 1900MHz city. (Boston)
When I touch my phone indoors, and especially in my house, the signal drops down to EDGE or GPRS. As soon as I let go it slowly rises back to 3-4 bars of either 3G UMTS:3 or 4G HSPAP:15. So it's not really that weak of a signal.
I have already replaced the sim card with a new one. I tried an AT&T sim card in my phone and everything worked as expected including LTE. My sim card in an unlocked but otherwise stock SGS3 behaves just as wonky as in my phone.
When i'm on CM 10.1 the switch is in between G/GRPS and 3G/UMTS:3. When i'm on the stock samsung ROM it's between E/EDGE and 4G/HSPAP:15 or HSPA:11.
This. Makes. No. Sense.
Any help would be awesome. Any direction (different forum section, forum, IRC channel, tutorial, guide) would be awesome as well.
Thanks for even reading!
