[Q] Network issues on CM9/CM10 - AT&T Samsung Galaxy S II Skyrocket SGH-I727

I haven't had any luck searching for answers in the forums, so here goes.
Current Setup:
- Unlocked SGH-I727
- Kernel, 3.0.49-KingKangersOne.12-g590eeda-dirty
- ROM, CM 10.0.0
- CMR v6.0.1.4
A couple of months ago I flashed CM9 and everything worked pretty well. Stable CM10 came out so I flashed it. I noticed the network was significantly more sluggish than on CM9.
Using Speed Test on CM9 before this mess I was getting < 30ms ping, 5+M Down, 2+M Up. On CM10 it's now >250ms ping, 8k down (not a typo), and about 250k up.
I played around with the network settings, making sure they were correct for my carrier. Nothing I did seemed to fix the problem. So, I wiped data/factory, cache and davlik, and then restored my CM9 backup. It came back up like everything was fine, except the network issues now were happening on this version, too.
Flash forward. I've tried reinstalling CM10 again, this time from scratch after wiping everything and formatting /system. Twice with a reboot in between. I even flashed an updated kernel for JB (listed above. It used to be 3.0.49 cyanogenmod kernel blinky-ghost when I was running CM9). I still get the network issues. I'm on a 4g/LTE network (ATT via Straight Talk) and am using all the right settings on the ST support site.
One thing I've noticed on both of CM9 and CM10 now is that I can't change the Network Mode setting. It's set to GSM/WCDMA. If I try to set it to LTE/GSM/WCDMA it just switches back to GSM/WCDMA.
Oh, I also deleted other APNs that I wasn't using. The only one I have is the one configured for Straight Talk.
So there it is. Anyone have any suggestions? Are there bad config files somewhere I can delete?

Aokp data not working?

Does the aokp rom contain a bug where the data wont be able to work or something?

next time ask in the ROM's Thread.
but as far as i know it does not. im using build 31 and its working fine.
try pulling out the battery for a few seconds then putting it back in and booting up.
Same here...data working fine in aokp.
Forgot to mention that there is an issue with data dropping in ALL 4.04 ROMs, including other phones.

The issue behind this here is that for whatever reason, the APN settings always seem to get lost. Sometimes the actually load properly and boom data. Then perhaps you leave wifi on and then most (at least all of the ICS roms I've used) drop the APN.The APN is what handles the data verification.
EDIT: As of recently, I have discovered that data is working fairly well on AOKP. I just reset the APN under its menu, then rebooted. Make sure you're running the correct RIL; it does help. Besides that, I've found that fix permission sometimes screws with APN recovery. So fix permissions, reset APN, and enjoy data coming back.

sky ice network issues anyone else?

ok I tried download new UL2 modem I follwed dirrections first off NO ltw (maybe not in my area) but 4g icon only 2nd my download speed like .15mb
then I reflashed the UL4 modem one comes with now I get decent speeds but seems cut off a lot.. this isn't huge issue as I use wifi at home but when im out and about (which havn't tested yet) im not sure.
now I did follow UL2 let modem direction wondering if changed setting RAT setting shouldn't have... if u reflash modem to rat settings go back? when flashing modems back forth I read you delete Dcache and cache which I did but am I missing something? something else do after or something... thanks
when downloading with just network it cuts out stops in middle of download ... i dunno what deal is anyone else got info on this? if I reflash a modem back do i need fix permsions?
well i flashed orginal modem working alright guess thought icerom have better donwload speeds but wow its slick and clean looking I really like it :O) yaaaa
I had no issues with the ucld2 radio while I briefly tried it. I'm going to be honest a say u don't seem experienced enough to be messing with the RAT settings of the radio, and should leave the default settings alone. On first boot after install dial *#2263# and set to auto, then menu > end, and reboot.
Make sure your apn is set correctly, especially if you are with rogers. Using the ltemobile.apn with the skyrocket even in an area without late results in data drop outs, as the phone searches for late signal. Same goes for AT&T. Make sure you are using 3g apn values, which will work fine for 4g.
I'm having the same problem. I tried Sky ICS 4.2a, then 4.2a-8, then 4.2d, and now 4.2a-9.
I've been using UCLD2 on these and had no problems, until today when I installed 4.2a-9 and all of a sudden I can't stay on LTE more than a couple minutes. It drops down to HSPA and drops the data entirely. I've NEVER had this problem, and I've tried every radio there is. I flashed back to UCLC4 and I'm still having the problem.
I'm searching the forums for a fix right now. I might just wipe again and start over with the base/modem.
EDIT: I've tried changing the RAT on both new radios by pulling the SIM, setting LTE/ALL, then Automatic. No change.

please help me to understand what is going on

Basically this is a WiFi issue with all CM10/AOKP fresh installed after Sep the 11th.
I said Sep the 11th because that is the best refference I can find.
If I flash any CM10?AOKP based ROM released after that date I lose wifi on 1st reboot after initial setup. To get the wifi working I have to toggle on the wifi manually, or toggle off and then on or reboot. I could not find a pattern. At the end the problem is that the wifi does not start on boot by itself. Let me be very clear here. Fresh flash.
Now here is the strange thing. I have several nands for Paranoid, CM10, SlimBean (unfortunately none for AOKP), taken pervious to that date and if I dirty flash to the last release everything works fine. No problems with the wifi.
The stock ROMs all of them work fine, fresh or dirty flashed.
I googled the internet and checked xda and other forums. I found just couple of similar situations but with no working solution .
One of them says that you have to odin back to stock, connect to wifi and then flash CM10. I did that and no go.
I tried different routers in different wireless configurations, same problem. Static ip and stuff.
Sometimes I get the wifi network "not in range" or the toggle for wifi in setting semi off or on.
If this is a wifi driver problem then:
1. can I get an old CM10/AOKP driver injected to the new releases?
2. why when I dirty flash the old driver (present in nand) does not get overwritten?
3. did you see anywhere a similar problem or it's only me.
Thanks in advance for your help.
same issues here on any build of aokp. wifi works until after a restart. i get the out of range error or wps failed. i have to shut off wifi and turn it on to connect. really annoying. funny thing is on ics i have no issues with wifi auto connecting.
ideas? Kinda weird only a small handful of people have this going on.
I've noticed WiFi issues also while on cm10. Lately I've noticed WiFi becoming better in more recent nightlies. However I've been doing clean flashes, and not restoring any system settings from backups. Even unclicking the boxes from the initial startup that allows Google to backup and restore settings on the phone. I'm assuming that possibly some setting/config is being restored causing the issue... just a thought

Nope i dont restore anything and always do a fresh clean install. If i had to guess its a buggy wifi driver that causes issues with certain routers. That would explain why very few have our issues. I guess for now ill stick to beans rom and wait for the jb ota.
Its worse than i thought as i have this issue on all the aosp varients. I just tried cm10, all aokp, liquid and slimbean. Same wifi error. I nandroid back to beans ics rom and everything is fine. Its got to be a wifi driver issue. There has to be more than myself and the op having this issue.

Signal issues

I've flashed different radios and the oxygen firmware, still my signal fluctuates all without me moving the phone on my desk. Ideas?
Signal also drops out for no reason.
I'm having the same issue with mine as well, bumping your thread to get it noticed. I haven't flashed a different radio, but I'm running the stock COS12.1 ROM, never rooted, and always updated via OTA updates. I think this occured with COS12 as well, but I'm noticing it more with 12.1. I've also noticed that it takes the phone quite a while to switch over from WiFI to LTE when I leave the house...not sure if it's related.
I'm looking to avoid doing any modding to my phone at the moment because I really need to have it active at all times to receive calls, but the fact that it randomly loses signal is frustrating.
I logged the network activity last night over the course of several hours at 10 second intervals. [Edit: Phone was stationary on my nightstand the whole time with the occasional picking it up to look at the time.] There are quite a few points where signal is lost. Usually it's only for a few seconds, but it seems like it's enough to miss calls (what prompted me to log the signal is when I received a voicemail but did not have any missed calls).
Does anyone know if there's a fix for this? The app I used for logging is "Network Monitor" from the Play Store.
Still not convinced after flashing 44s didn't help then flashing the updated Oxygen firmware still nothing. My signal will go from to bars to emergency calls only. Deleted all the Unneeded apns.
Rom: Resurrection Remix.
Service Provider: Net10 using AT&T towers.
When did this start happening: As soon as I updated my firmware to the latest Cm 12.1 per RR thread.
I've tried everything i can think of, even using the hidden phone menu to select LTE/GSM. Still no luck. Every once in a while when i am at a place where i get good signal this isn't an issue. Seems to happen when i get 3 bars or less.

Just confirming this as an issue on Ting, I was on the 12.1 Nightly's, I also tried Exodus. I can be at close to full service and for some reason signal will drop out constantly, yesterday I had a 22% time without signal according to battery stats.
Clicking on network operators and selecting the correct one only temperately fixes the problem.
Solved the same exact issue on my phone
Had the same issue on mine after updating to 12.1 OTA. Selecting my APN didn't work, my connection kept going in and out to my carrier. It was as though the radio would shut off and then turn back on every 15 seconds or so. I reset default APN's, and all is back to normal T-Mobile, for what it's worth.

I've tried that no luck.
I fixed this on my phone, I reset to default apns, selected the correct one and then deleted all APNs that weren't mine. According to GSam i'm at 57% in 15h 34m
No luck, tried that.
Should I try to fastboot flash the 44s modem?
I've been using Phil's cwm and I don't think it's flashing right. Because I went back to a May 2015 nightly of cm 12.1 then flashed 44s and nuclearslim 1.3 ,bam everything works perfectly.

You can't use a KitKat modem with a Lollipop ROM or you'll have prox sensor issues.
I have the proximity fix file, should I fastboot flash though.
I think Ill just fastboot flash the 44s, and why isn't Phil's saving my backups. It wiped them when I wiped the user info. Left my other files.

Not sure, I never had that issue. switched to the
XNPH05Q modem after my phone for what ever reason was stuck in a bootloop. I had this problem solved before it bootlooped. Here I am back with the same problem, I even followed the steps that i used to fix it last time. Nope not working this time, Some how Using XenonHd, my signal stength is all over whille sitting in the same place. Starting to think that my sim card may be going downhill. Any ideas?

Lost LTE and internet access on some Wi-Fi networks after flashing Cyanogenmod

This is the first help post for anything tech-related that I've ever posted- I'm usually good enough with Google to fix my own problems, but this one has me flustered.
Until yesterday I was running DigitalHigh's GPE ROM but decided to give Cyanogenmod another try after some persistent lag issues. Everything went fine during the install until I noticed that I was stuck on 3G no matter what I did- airplane mode, reboot, clear the cache, try to update APN settings, etc., nothing helped. Additionally, while the phone will connect to my home wireless network, it has a ! next to the connection symbol despite my being able to use the network with my laptop. The funny thing is, this only happens with some networks. Neither my home network nor the network at work will give me internet access, but if I plug an ethernet cable into my laptop and create an access point that way, I'm fine.
Here's what I've tried so far after scouring these and other forums:
-Reverted back to the previous ROM
-Flashed new firmware
-Flashed two new kernels
-Tried every different APN setting I can think of
-Popped out my sim card, waited a bit, and popped it back in
-Rebooted countless times
-Cleared every cache I can think of
-updated TWRP
There's probably more that I can't think of off the top of my head as well. Does anybody have any idea what on earth has happened to my phone?
