Since I can't post in the dev thread, [ROM][Official]MyTouch4G Slide CyanogenMod 9 #1644084, I'm posting here.
I've been having the network issue intermittently, where sometimes my phone won't connect to data. Others in the CM9 thread have reported similar problems.
The problem:
Status bar indicator is just bars with no letter, but intermittently shows a ((2|3)?G|H){1} for a moment, and then goes back to just bars.
Phone info activity shows GPRS service as disconnected.
Issue first occurred for me 2012-06-19
Possible solution:
A few days ago I noticed that it only happens to me after I go to the basement or some other area where there is no cell signal. I haven't been able to reliably reproduce the problem, BUT: oddly enough, when experiencing the problem, briefly visiting one of these locations again actually solves the issue (each and every time, ~15 times so far). Sometimes it takes a few trips in to and out of the dead zone, but it always works for me.
I want to see if this works for others, and if anyone has ideas of why this might be?
I don't know what information might be helpful to gather, so tips would be great.
My hope is that this can help others with this issue, and maybe that it will lead to a permanent fix.
Unfortunately I haven't had a chance to join the IRC lately and explain this to korny/tbladen.

I saw that thread but wasn't sure if it was the same issue, since I've only had it with this CM9 Alpha (4|5) ROM and not others. Good point though, should suggest this. Thanks!
It looks like others are still seeing this issue: http://forum.xda-developers.com/showthread.php?p=28848868
Any chance someone could post something about this on there?

I am suffering from the suspend_backoff wakelock. Under the partial wakelocks section the highest counts are "WifiStateMachine" and "DHCP". I am S-off and running Viper 3.2.6 with the kernel it comes with. I have done a full wipe (wipe cache, dalvik cache, even flashed Calkulin's_FORMAT_ALL_for_One_XL.zip because I previously changed recoveries), and I have not installed any extra apps except for BetterBatteryStats.
Now, I believe I have read through every forum thread about this issue. No, I do not have Chrome installed. "Wifi Best Performace" is unchecked. I am not signed into any accounts, including Google or Facebook. Location services are disabled. It only occurs when Wifi is turned on. The closest thread I've come across would be:

The thing is, I am using my college campus's internet, so I cannot simply get rid of the "broadcast storm," if it even is the problem. If this were my problem, however, wouldn't many Android phone users on the college campus also be suffering from suspend_backoff? I guess the next step for investigating this problem would be to inspect my friends' Android phones and see if they have the same problem. I can't imagine this being a widespread problem though, as there would be many more complaints about this issue.
Does anyone have any suggestions/thoughts to help me out? I will appreciate any feedback
Also, I have monitored Wifi network activity on my phone using Wireshark, and I got a billion DHCP solicit requests. I do not know if this is pertinent information...

Get a separate router to grab the Internet and stay off campus lan? This way you can have your own lan while using campus Internet.
This is purely speculation of course. I've never had this issue or tried to resolve an issue like this. The real fix would be to ask your net administrator to incorporate the spanning tree protocol.

Thanks for responding. I don't have a router, and I don't want to spend money on one. Here is another thread for another phone that seems to have the same issue:
http://forum.xda-developers.com/showthread.php?t=1915859
The OP is getting another wakelock WLAN_RX_WAKE, but his symptons are the exact same. Plus, he is using a university network too. Doesn't seem to be related to phones, as the OP is using a Galaxy Nexus, while the last post in that thread indicates that S3s can have the same problem. Furthermore, the OP states that his phone used to be fine until he flashed CM10, after which the wakelock started appearing. Then even after full wipes, the issue persists!!!!! I have also flashed CM10 in the past. That thread has not been resolved at all. What is going on??
Edit: I found another thread with similar problems:

If the problem isn't with the device, how do you expect to fix it by doing something with your device?
I'm with exad, the issue sounds like it's with the wifi setup at your university. Maybe talk to the admins there??
Ok, I will try talking to the net admins here. Also, just to be sure it's a network problem, I'm trying to install BetterBatteryStats on my friends' phones to see if they are also experiencing the same thing on Wifi. So far, 3 out of the 3 people I have asked had less than 5% battery left when I asked them...I managed to charge one of them up a little bit, but then BetterBatteryStats kept crashing on the phone. I will keep trying.
If you're afraid cm10 caused it. S-off if you're not already and run an ruu. That will return everything to stock. If it continues its the network. If not it was your phone and cm10.

Attached are my dmseg.txt and logcat.txt. I hope I did the logcat.txt correctly. I think the WifiStateMachine stuff in the logcat.txt should be more closely examined. I don't know what it means. Does it reveal anything?
Running an RUU seems like a significant time investment for me. Wouldn't I have to re-root my device, reflash a recovery, unlock bootloader and stuff? Plus, I don't know which RUU to use, so I would have to put time to do research. It even seems a little risky. I am S-off though.
I'm waiting on my friend's responses for their BetterBatteryStats logs. I really want to know what shows up, but they're taking their sweet time...If they are having the same problem, I can conclude for sure it's the network. Right now I think it's the network but have no concrete evidence.

run the ruu. the ruu takes 10 minutes and wipes everything.
the ruu doesn't relock the bootloader so you can just flash recovery after and flash a rom.
here's the list of ruus with links. pick the carrier your phone came from:

You can post whatever logcats and dmesgs you want. this is how you test to narrow down the cause.if i can invest the time to help you figure out the cause of your problem you can invest the time to complete the steps to figure out the cause. if its indeed cm10 there will most likely be no fix other than to not flash it.

I'm sorry if I implied that I would not run the RUU because it would take too much time. I just did not have the time at that moment to do enough research about it. I do not like to do things blind, so I spent an hour or two reading up on other people's situations. I decided that it is safe to go ahead and run the 3.18 RUU. In fact, it is running right now, and I really hope it's not going to brick.
Thanks exad for the help. The RUU worked fine. I can now say with 100% certainty it's the network that's causing the suspend_backoff wakelocks. I am completely stock and am not even signed into my gmail account. I turn off the Wifi, and the phone sleeps normally. With Wifi on, the suspend_backoff wakelock keeps the phone awake ~80% of the time. Now for the next step...getting my university to change its network protocol?? That seems like a daunting task for a single student at a university.

Either that or create your own network that only pulls only internet from the existing network. (Pure speculation, be prepaired to be able to return the router should it not work)
Sorry I couldn't offer a more feasible solution! Good luck friend!
I've been thinking about this problem, and I'm wondering:
Could this problem actually be Android's/the kernel's fault? In other words, could this problem be seen as a bug of Android/the kernel? Should the phone really wake up when it is connected to a certain network with lots of broadcast traffic? Couldn't the phone be programmed to ignore such traffic? From what I can see, this traffic should not even be waking the phone, as it is all DHCPv6 solict requests. What is also interesting to note is that it is DHCPv6 and not DHCP. I do not have any background in networking, but surfing the internet is still dominated by IPv4, correct? IPv6 is mainly for local networks?
I don't know what I'm getting at, but those are my thoughts...
The tittle says it all. I have stock 442 rom and have tried faux and franko kernel.
I have the wifi drop issue that is driving me crazy.
Has anyone tried a rom or a kernel that has fixed there wifi drop issue.
thanks

i dont have wifi drops using trinity and rastakat rom. but i dont use wifi very often. maybe it isnt an issue with your kernel, but an issue with your router?

Did you have any wifi drop before you tried those roms?
I tried everything I could find everywhere and my conclusion (along with a lot of others) is that there is something somewhere with the kernel or rom.
Also I know it is not my router cause I have a total of about 6 devices connected to it.(not all at the same time)

no.
but as i said, i dont use wifi very often, actually its pretty rare. but when i did, didnt have any drops.
I use WiFi as much as possible, just because I work in an old cotton mill so the signal strength in big, Victorian stone buildings is not good. I'm probably on WiFi for 21 out of 24 hours of the day. I've never experienced any drops on Any ROM / Kernel combination that were not attributed to a problem with the local network, so I'm not really sure how advice can be given.
Just because only 1 device has problems connecting to a particular router, doesn't mean the problem isn't the router. People are often surprised on facebook when they say "one iphone cant connect to my wireless router" and my advice of rebooting the router worked. Sure, it may not be the solution to the problem here but it is not uncommon that a router issue only affects 1 out of many devices so don't rule it out.
I get what you're saying but like I said I tried everything and nothing worked. Since the n5 has WiFi ac I was thinking of changing my router and then we will see. In the mean time I'm trying some ROMs using multirom.

Since there is no "major bug" with WiFi drop outs, it's unlikely that any ROM or kernel will resolve the issues you're having. They seem to be localised. Maybe you'll find something and I wish you good luck, but I doubt it.
I would change the channel on the router before I did anything else. You can use WiFi analyzer to check what channel is best or if another router that's close on the same channel is screwing yours up

You are probably most likely correct in your assessment of the problem. But the more I think about it, it sure does seem like there have been a lot of wifi complaints recently. More precisely, complaints about wifi not staying connected. I don't know, maybe there is an issue that only a very small percentage of people experience.
Rebooting the router is always the first thing that one should try, as you suggested. Also, firmware updates could potentially solve issues with certain routers. But, I will acknowledge that it is possible there is a hardware/software issue with the N5. Remember that battery drain issue that I and a few other people were complaining about? I think I fixed it. Switching to SlimKat and using the stock SlimKat kernel, I had 9 days of uptime before rebooting for a nandroid. I could never even get 25% of that using the stock ROM without seeing 5-8% per hour idle drain (not wakelocks, but perhaps kernel deep sleep issues). There is a bug in that stock ROM/kernel, somewhere, that is causing that issue for a handful of devices that have certain chip revisions. They are all made in batches, right? Just like no two CPUs will overclock or undervolt the same, why can't two wifi chips be different?
I'm constantly reminded of the N7 2013 touch screen fiasco. If you are not aware, some a sizable percentage of the N7 units have multi-touch problems. The touch screen quite literally goes ballistic if you touch it with more than one finger at a time. Some other models register touches where the screen wasn't touched (ghost touches). My first one had the ghost touch issue, RMAd, new one has been fine. Then there's the units with grounding issues, where the screen only works properly on some surfaces and not others.
They are still selling affected units. They know the problem exists. They said they fixed it. And they did, for some. Google is trying to fix a hardware issue with software. They know the hardware is faulty, but sell the devices anyhow, and will deal with RMAs as they pop up, and ignore legitimate complaints. The rep I talked to on the phone (very nice, btw), wasn't going to give me an RMA. I had to press the issue to get a replacement.
I was one who subscribed to the theory that you shouldn't buy a brand new model device, because invariably, there will be bugs that will need to be worked out in the manufacturing process. This theory has zero merit. At least not with LG and Asus.
If after doing all the router stuff the problem isn't fixed, @nitramus, try using SlimKat with the SK kernel.
Thank you so much for that response and some acknowledgment. I started testing ROMs and already a good change. Compared to atom rom,/kernel I can now use a y otg cable and simultaneously charge the phone and use mass storage.

I'm back in love with my Transformer since installing KatKiss Rom. However, my download speed is about 1/10th of what it should be. When running the speedtest.net app I'm getting about 3.7Mbps download and upload was the normal (for me) 10Mbps. My dl speed should be closer to at least 40-45 Mbps. I've search for similar issues however have only been able to see problems people have with the inability to actually connect. I can connect to the network/Internet with not problem there. It's just my dl speed is significantly slower than it should be.
Any ideas or suggestions on resolving this issue would be greatly appreciated.
TIA
Sorry, forgot to add, I'm running KatKiss 4.4.4_32b

Thanks for the reply but I had already checked that. Besides, if that was set incorrectly, wouldn't that prevent any connections at all? My problem isn't a connection issue. It is a speed issue.
Try KK #33, maybe it has been fixed since 32b

I was thinking of doing that however I was hoping there was another option. I thought it was funny that my Transformer hasn't already informed me that there was an update available. Oh well. I'll try and get to it sometime this weekend. Unfortunately, homework takes priority. Only 10 more weeks until I graduate with my BSIT!!
Generally only stock ROMs get OTA updates, Custom ROMs need updating manually, iirc back in the days, one of the custom ROM devs did manage to get OTA updates running with his custom ROMs, but never seen that again for years
Need to keep checking the dev thread for new custom ROMs, everything is manual apart from app updates
Good luck with your BSIT

Well, tried to upgrade to v33 but still no go. Wifi speed is still about a 10th of what it should be. I'm definitely connected but not very fast. Also, I forgot to mention it in my previous posts but the auto-rotate function doesn't work either. It will open apps in the orientation that the app needs but will not switch between land and port when rotated on the home screen.
I'm going to try an earlier version (4.4.2 v26) because I've read that this might fix the auto-rotate issue at least.
Still lovin the Rom...just a couple hiccups that need to be ironed out.

Have you seen faster speeds than that with the TF101 before?
You'll likely only connect at around 65Mbps with the TF
With a Wireless G 54Mbps you get about 20-30Mbps because of overheads (Encryption etc)
That results in around 2-3MB/s real world download speeds
So with 65Mbps, you won't see a great deal more than that
Plus those speedtest apps are pretty crappy if Im honest, best to download something you get good speeds on your PC from, and test it on the TF

Status update:
I've tried two different Recoveries (CWM & TWRP) and two different ROMs (KatKiss and OmniROM). All have installed with no problems however I still haven't resolved the slow download speed issue. I'm still baffled as to why my upload speed is normal. Side by side comparison with my wife's non-rooted stock TF101 in the same room had normal download speeds which were 10 times as fast as my TF101.
Any other ideas I can explore?
Using 4.4.4_034 in the US I had to choose "EMEA & rest of world" to get 36Mb/s.

Bit of a strange one indeed, you could try changing router settings just in case, change the wireless channel to a clearer one, as above use WiFi Analyser to check the best channel to use
Other options would be to clear the DHCP pool on the router, forcing all devices to reconnect on a new IP
On the tablet side, you could try setting a static IP instead of using DHCP
Try a different DNS server, not that it should affect the download speed, but 8.8.8.8 and 8.8.4.4 are Googles public DNS servers
(Gateway is the IP of your router)
Solved - Still not sure why though.
I've somehow solved my download speed issue. I took my tablet to work and discovered that my WiFi speeds were what they should be so I knew it wasn't a device issue. Brought it back home and connected to my home wireless and found my speed issue was miraculously fixed. I'm still not sure why but I'm guessing something was reset or timed out in the router to where the tablet was now a new device. I don't know why removing the device from the network for a few hours would have a different effect than a manual reboot of the router. I guess I'll keep this in my bag of network troubleshooting tricks for the future.
Pleased you got it sorted
Hello! Thanks for taking time to help me out!
Here is what is happening; I just recently updated my phone to Marshmallow and am running XtraSmooth with EXKernel. I live in China and had to follow the tutorial to change one of my bands to get LTE here. Of course everything was working fine before I updated to M6.
I can go into the 'Testing' Menu (*#*#4636#*#*) and switch to LTE only and LTE works great, however I then can not receive or send calls or text messages. When I do switch to LTE Only the LTE connection is usually much stronger than when not on LTE. For now I leave it on LTE/GSM (auto).
When I wake up my phone it is usually connected to 3g or edge, after a while it connects to H but then jumps back to 3g, and never seems to connect to LTE.
Is there a new feature I am not aware of that is causing this issue that I could turn off?

Hello! Thanks for taking time to help me out!
Here is what is happening; I just recently updated my phone to Marshmallow and am running XtraSmooth with EXKernel. I live in China and had to follow the tutorial to change one of my bands to get LTE here. Of course everything was working fine before I updated to M6.
I can go into the 'Testing' Menu (*#*#4636#*#*) and switch to LTE only and LTE works great, however I then can not receive or send calls or text messages. When I do switch to LTE Only the LTE connection is usually much stronger than when not on LTE. For now I leave it on LTE/GSM (auto).
When I wake up my phone it is usually connected to 3g or edge, after a while it connects to H but then jumps back to 3g, and never seems to connect to LTE.
Is there a new feature I am not aware of that is causing this issue that I could turn off?
Thanks Again,
Chris

sounds like you need to downgrade. the mod probably doesn't work with your carrier on the newest update. I don't know for sure but your can ask in the thread where your got the LTE Band mods from.

Thanks for your reply! I really appreciate your help!
This is the thread I got the hack/mod from for the LTE bands. I did re-perform the hack to verify it is still functioning. A few users in that thread reported it working with Marshmallow.
I was just out and about and I did notice LTE being used occasionally, sometime working sometimes not -- Oddly enough H seemed to not work at all giving DNS errors in chrome.
I am about to just restore my phone back to Lollipop with the twrp image I have... But I really do like to stay update to date with the latest OS. I also wanted to try a Chinese ROM like MIUI but they are still stuck on kitkat for the N5 and I don't want to go that far back... If the phone is still performing poorly and no one knows what is going on in a day or two I may revert back just to save myself the headache! I may also try a different ROM like Chroma to see if it helps.
If anyone else has ideas please let me know! Thank you!

Last thought it make sure you wiped everything in TWRP before flashing the ROM and make sure the modem you're using is marshmallow compatible. if you performed the steps on modem that isn't compatible, that could have caused your issues. I hope this is helpful to you. and feel free to hit the like :silly::good:

I don't know a lot about phones... When you say modem when referring to phones do you mean radio? I flashed the stock M6 factory Google Image by running the flash-all.bat. After that I flashed the ROM. Should doing this have taken care of that
Should I attempt to flash some other things? If so can you point me in the right direction.
Also it seems to be working a little better, steadily connected to LTE, however I get many many DNS errors; again I live in China. I am going to try to set custom DNS that I know works well here, when I get home from school. Is there a good app for this?

first, when you see modem and radio, those are the same file. and yes you flashed it correctly using the "flash-all.bat." :good: so you have the latest modem for the nexus 5. The DNS errors could mean many things. DNS depends on carrier, proxys they may be using, phone settings, etc. also for next time before you flash any files, read the stickies and rules. If not people may get mad at you & call you names if you ask question that already have answers inside of the rules and stickies

focus on fixing the LTE problem first completely than deal with the DNS so you don't confuse the problems.

I think the LTE issue has mostly resolved itself. My house must be in a very poorly covered area and so I gets disconnected.
The big thing now is dns issues... Is there a good way to change it or do tests for issues?
Thanks

why is the DNS an issue, what exactly is the problem?

I'm sorry, this must seem crazy. So when I am connected to WiFi I can surf the internet just fine (as well as we can here) when on 3G or H data connection it works. But when I'm on LTE I cannot browse. Chrome gives a DNS_PROBE_FINISHED_NXDOMAIN error (for websites like bing.com and baidu.com [like chinese google]).

hmmm interesting. have you tried google searching the issue? someone else who has your phone and carrier may have had the issue, nexus 5 is pretty common.
also what carrier do you have?

I have a little, and I really cant find anything. It seems I may not be getting an IP at all. I d/l a DNS Switcher app and it has a button to show current network settings and ip displays as 0.0.0.0 dns as 0.0.0.0
I may have to modify my searches.

Honestly if those settings are coming up using the cell network, idk. Be certain your APN settings are correct since that could effect it. Lastly if that didn't happen with out the custom radio than you may be having some issues with the mod. go back to the thread and make sure you did everything like they said. also try using a different browser, I heard something about google and China not being good with each other

I really appreciate you sticking around and helping me out! I am at school or work all day so I only have short evenings to trouble shoot. So here is what I experienced today;
I can now steadily connect to LTE (even in areas I was having trouble with before). Sometimes, when I connect to wifi then disconnect and therefore reconnect to LTE it doesn't handle the switch-over very well and gives issues with the connection (the NXDOMAIN errors or, more rarely, no internet connection at all). I downloaded LTE Discovery which showed me I am connected on band 3 which means the 'hack' successfully applied. I also asked over on their post and they said It will stay across a factory update. To fix the connection errors I can usually restart my phone or play with the APNs (switch back and forth), merely turning data off then back on does not fix the issue.
My next idea is to switch ROMs then downgrade. but oddly enough, right now, no matter what I do it works... This is nuts, haha.

No problem, and try different modems first, that could clear up the issue. than try some different ROMs and going back to stock like you said.. Also you never mentioned what you doing when you get those DNS related errors. don't forget to hit thanks man, def appreciated.
also, be sure no one else in your area, with your service provider is having the same issue.
