Materials:
I have Shadow Kernel v0.5 patched to my clean install of CM9 (wiped data/cache/dalvik); overclocked to 1200Mhz using the built-in CM9 performance settings with InteractiveX governor.
Issue:
Every time I try to enable the built-in CM9 wifi hotspot, it seems to just automatically deactivate.
Procedure:
While having wifi on and successfully connected to the internet via my home router/work router, I tap the check-mark to activate the hot-spot, it displays that it is attempting to activate wifi (even though it is already on) and then displays the small icon indicating that wifi hotspot is active; after a few hundred milliseconds it proceeds to display that it is deactivating wifi and we are back at square one (but now the wifi is off).
Results:
This issue is repeatable. I can duplicate this problem consistently even after doing reboots. I have also tried to activate the hotspot with the wifi preemptively off or combined with 4G on/off and it seems to hang and occasionally crash to an automatic reboot when attempting to activate wifi when hotspot is toggled on.
Question:
Is anyone else having similar issues? Or is it simply my phone acting retarded?
Edit:
- I have tried down-clocking the CPU from 1200Mhz to 1100Mhz and it seems to be spotty with reliability regarding staying an active hot-spot.
- I have tried down-clocking the CPU from 1100Mhz to stock 1000Mhz and the hotspot is still unreliable.
- I have kept the clock-rate at stock 1000Mhz and switched the governor from InteractiveX to stock Conservative, the hotspot stays on, but it fails to assign IP addresses to anything. :'(
1. Don't flash a custom kernel. To me, OC is a joke. It may speed up the device, but it just drains battery and the phone is already fast enough. They bring up issues that can easily be avoided.
2. Wifi will never work as a hotspot. 4G will work eventually, however the whole idea of tethering is using your signal to create what is basically just wifi for other people, or your computer. Why would you or anyone else need a hotspot if wifi is already available? That's just redundant.
3. If you use 4G frequently, there is an app on the Android Market (or should I say Play Store? lol) that will allow you to create a wireless hotspot based on your 4G connection, however it is not yet built in to the system.
Hope this helps.
Hello Acer, thanks for the reply!

Noted. I will stay at stock clock-rate then, but that custom kernel offers some improvements that I feel are important.

I believe I have caused a misunderstanding, I wish to utilize my phone as a wifi hotspot to access my phones 3G/4G Wimax. I have done this successfully with stock Samsung roms. My goal is to cancel my Comcast cable internet because they are raping me without a condom right now.

CM9 allows you to do this without an app.

You were very helpful! :-D
I too had trouble initializing the hotspot built in to CM9. It would activate then deactivate. I left it on, rebooted, then went to try again, it activated, deactivated then reactivated and stayed on. Then it worked fine after that.

You are supposed to be connected to data, not wifi, since that's what you're trying to tether other devices to. When you press the Portable Wifi hotspot button, it says "turning on wifi...", think of that as saying "turning on wifi hotspot", not wifi as in your router.
Turn OFF wifi, turn ON 4g/3g, make sure it's connected to data, then turn on portable hotspot. However, you did mention that you've tried several combinations. I have the same setup as you and this never fails for me. I think I got a reboot once awhile ago but that's it.
the OC is not the problem, I'm also at 1200mhz on shadow.
I am having this exact same problem after flashing cm9 beta 0

I don't know if this has been posted already, but I was struggling trying to find solutions so I thought I would post what worked for me.
After updating to froyo rooted deodexed stock rom, my wifi tether became very unstable. It would say it was connected, but my computer would lose internet access and would only reconnect after I stopped and restarted wireless tether.
The day it started to behave again I did the following:
- Turned "Find My Location" off in Shopsavvy
(this did not make a noticeable difference, but I left it like that anyway, just in case)
- Upgraded wireless tether to 2.0.5-pre8
- Installed Wifinder to make sure I was using a clear channel in wireless tether
(The default channel I was on was clear from what I could tell, but I went ahead and changed it to 1 in the wireless tether settings anyway)
- On my computer, I right clicked on the wireless tether connection, selected properties, connection, and put a checkbox in "connect even if the network is not broadcasting its name (SSID)", then ok.
(I believe I read some people saying that the phone was stopping broadcasting the SSID when the internet was dropping, which is why I did this)
After those changes, I was able to stay connected for hours versus minutes, but after restarting the phone I have been able to stay connected until I disconnect.
The only time it has disconnected without me physically turning off wifi tether since then was a couple of times trying to test my upload speed, but not every time. I think there must be something they are doing to shut down the connection when large or aggressive uploads are detected or something.
I was actually having this same problem on the old Fresh .02 ROM I was using. Thanks for the info I will give what you said a try!
I was having the same problems as well...it seemed like every 10 minutes it would just stop but still said I was connected when clearly I wasn't. I will have to test this tonight when I get home...thanks so much!
Can anyone confirm this works? I'm having major issues with all data connection dropping after a few minutes of being online. What I've noticed is that the 3G indicator in the notification bar will actually disappear momentarily, then reappear, but once it reappears...I'm not able to connect further until I restart the tether app.

I would change your version of wireless tether first. Which one are you using? I am using 7 now, but I believe 8 was best for me.

Using "Wireless Tether for Root Users 2.0.5-pre11" now...haven't tried it with this version however I was using pre9 and that version was causing the 3G problems that I described in my last post.
I had this same issue. When I went into the wireless tether application and changed it to use channel one everything started working perfectly.

I'll try that and report my results...really annoying problem, ya know?
I think the "aggressive download" portion is accurate. I can stay connected for hours with a little web browsing going on; however, start up a torrent or connect to my PS3 and it disconnects in 5-10 minutes. I'll try the SSID broadcast later tonight though and test it under heavy load.

My issue isn't "aggressive downloads" - a PS3 connection doesn't require a lot of bandwidth, just a low latency connection - which is probably the reason you are disconnected. I use my wireless tether for playing online games from my computer. When it is actually working and playing well, its running 8-12 kbit/sec, which is very low bandwidth. It's only when the 3G indicator disappears that my whole connection is lost and I have to restart my game and restart Wireless Tether as well. FWIW my latency while playing is roughly 400-500ms - high, but the game tolerates it.
Ok, I have seen this on 2.3.5 builds of CM7, Deck's ROM and OMFGB. What is going on with wifi on 2.3.5? It's causing some kind of wakelock apparently. Look at the right hand side of the battery graph and compare the "awake" to "wifi" time. I had my wifi to sleep when the screen turns off, so it went away when wifi was turned off. But then if I connect to wifi again with the screen off, it causes wakelock. Is this a known issue? I have tried googling and can't find anything about this. Surely I can't be the only one.
On Sense roms I can leave my wifi sleep policy as "never" and it doesn't cause any issues.
I'm using the CM7 nightly build 180 (2.3.5). I'm using Tiamat Kernel SBC. My WIFI sleep policy is set to never. It's been unplugged for about 8 hrs 45 minutes and connected to my WIFI. It's been on standby for the most part and it's at 99%.
WiFi totally unrealiable on the AT&T Atrix 2 (MB865)

I too am seeing all sorts of issues with WiFi on my Atrix2 (MB865) which is also running Android 2.3.5. As a matter of fact, I have TWO of these, because my wife got one also, and it has the same problems. To be specific, both phones will drop 128Kbps streams and fall back to 24Kbps, if the alternate slower speed is offered. This constant dropping of audio stream is the most annoying problem, but the phone also will spontaneously disable WiFi. After manually re-enabling, it can take up to a minute to reconnect to the AP (the happens at home and at work).
When connected, a speed test might show something like ~100Kbps down. But disabling and reconnecting a few times will help get it back to a good ~20Mbps down again. Sometimes when connected ad showing a FULL STRENGTH WiFi status icon, I am still not able to get any data whatsoever, just as if the WiFi is not even enabled. Examining this with WiFi Analyzer shows that it detects no AP's whatsoever, even while the status icon shows a FULL STRENGTH connection. Again, disabling/enabling can correct this issue.
Just to prove it's not my home AP, I have an old HTC Hero running a CM7 nightly build from 9/1/11 kernel 2.6.29-6 (which is also Android 2.3.5).
My old HTC Hero connects quickly/flawlessly and holds a constants steady 128Kbps stream all day without fail.
Why can't these carriers (AT&T in this case) put out a reliable Android build. I can't help it, but my paranoid mind makes me think it could be purposefully done to force customers to use precious bytes form their costly data plans. They certainly would have no incentives to make WiFi work efficiently.
Anybody got an ETA on CM7 for this phone?

KenB
It's on LG8, it doesn't happen to my home wifi, but ANY other WiFi, I have to do this process.
Slide down Notification bar, Toggle WiFi, hit settings, select WiFi to connect (always an open one that needs to be authenticated via website.), says connected, but instantly disconnects and I lose data for ~3-5 seconds and it disconnects the WiFi. Then I have to go back into WiFi and reconnect. The WiFi is just disconnected from always says "saved".
It happens on any LG8 rom I am on, including the 15 toggle mod roms. Not sure if it's my device or what.

I have the problem too. Stock or Blazer or Team Sonic. Happened on 2 phones so it doesn't seem HW related.
*#0011# then menu and wifi and turn off power save. Have to do this every time phone reboots but solves the problem.

What frequency is your WiFi access point or router using? There is a known bug introduced by the LG8 that borked your ability to select which frequency band to use or a hybrid setting, so the phone is stuck in whichever was selected before the LG8 update. So if your phone had been set for the 5 GHz band, then you applied the update, you could no longer connect to 2.4 GHz access points.
Interesting...have not tested but will look at this.
What a silly oversight on sumsungs part.

My router at home that doesn't have this issue is 2.4ghz. I'd assume the same at these WiFi hotspot points since some laptops still only support G freqs.

Hmm. I don't know what to make of that. I actually have never experienced this problem myself, and never changed my frequency setting under the old firmware. Can't even find a link right now to whatever forum post reported this problem in the first place.
I'm on LG8 stock and don't have wifi issues...weird

I have a dual band router and I know that mine will connect to either 2.4G or 5G, although it's usually on 2.4.

The way I understood the alleged bug, the problem only occurs if the user had changed the setting under the old firmware that included the Settings screen to do that. Then the Settings screen went away with the new firmware build.
Hi,
I am having problems with wifi drops under custom roms (I've tried several CM10 builds and AOKP's JB Milestone 1).
Under a rooted stock rom (UCLH9) and ATT installed kernel (3.0.8-985684) I get a very stable wifi connection.
However, if I install a different rom via ClockworkMod, I'll get wifi connections for ~ 30 seconds (or until data stops transmitting), and then it will drop out. I have to cycle the wifi on and off to re-establish a connection. Again, I'll stay connected for 30 seconds or less and wifi will drop again. The rest of the phone works fine.
Despite the dropped connection, the wifi icon (under settings) will say connected but show no signal bars. In addition, the phone nearly comes to a halt and hangs, as if all processes are being devoted to reconnecting.
This happens on at least two routers (one at home, one at work), so I don't think it is a router issue.
I've seen some people talk about the *#0011# dial code to turn off wifi sleep mode. If I dial this under the rooted stock rom, I'll get the menu as expected. But if I dial this code under either custom ROM first I see "USSD code running" and then I get an error "Connection problem or invalid MMI code."
If, after all this, I restore to the rooted stock ROM, wifi works and everything is fine.
Any suggestions for getting a wifi functional custom ROM installed would be appreciated.
Thanks
Avram
Sometimes getting a kernel for those type of problems fix it because they are basically replacing your phones access to your drivers (Wifi and so on)
This one puzzled me for a while. The rom comes preset to disable wifi after a certain amount of idle time. Go into Settings>Wireless & Networks>WiFi then press your settings button>Advanced> Keep Wifi On During Sleep> Set to Always. Maybe this is the fix to your problem.
This is happening to me right now with my LG G2, WIFI is stable on the stock rom but drops constantly with any custom rom. Did anyone find a fix for this?
I have tried several fixes including WIFI on during sleep to always, WIFI optimization off, different freq bands, I can't figure this one out...
I have a question. I have "keep WIFI on during sleep" option set to "Never".
When I wake up my phone from sleep after 30 minutes or more of not using it, the wifi does not reactivate itself (it's off, no icon in statusbar), but when I go to settings, it says that Wifi is enabled. Just like in the picture below...
I want to know if this is normal or what? Happens to me on both stock and custom rom.
EDIT :
I fixed this by putting my Wi-Fi frequency band from 2.4 GHz to "Automatic" in advanced wifi settings. Htc and google really need to fix their ****!
I also disabled ipv6 in my router settings, not sure if that helped
Sadly for you, it works as expected for me. I let my phone sit for about 40 mins hoping I wouldn't get a text. Picked it up and the Wi-Fi turned on and connected right away.
Stock Rom (1.91.617.1)

This is just plain weird for me. Not a real problem, but strange, maybe has something to do with my wifi connection (router).
Thanks for the reply!
Just confirmed that one other guy that just got the phone has the same issue.

I have had the WiFi Frequency Band set to Automatic since I got the HTC 10. I came looking for this topic because of what mine does. When I wake up the screen, there is often a message on the screen "wifi has disconnected", and it will show connected to mobile data in the notification bar. It usually will reconnect to WiFi within a few seconds. But it is annoying, so I am looking for a fix, if there is one. I turned on the setting to keep it on WiFi during sleep a couple days ago, but it didn't change this behavior.
From what I am reading here, this sounds like it is common to the HTC 10 regardless of that setting. I am therefore thinking perhaps the "wifi has disconnected" message is actually left over and still on the display from when I turned the display off? But what I don't understand is that I get notifications such as incoming email and hangouts messages while the display is still sleeping. Unless those are coming via the mobile data connection. Perhaps I should try turning off mobile data and leaving wifi on to test if it still does that, but obviously leaving the mobile radio connection off is not desireable, even if that did help. Does the HTC 10 silently always switch to a mobile connection and turn off wifi whenever the screen is off, meaning that keep wifi on setting is flawed?

No. You probably have "Auto-switch to mobile network" enabled in advanced wifi settings.

Thank you for replying. The only 3 boxes I have checked in WiFi > Advanced are as follows:
WiFi Notification
Show Wi-Fi pop-up
Hotspot sign-in
All the other check boxes are blank.
So I have similar problem. When I leave the house it switches to mobile network just fine. When I come back home it doesn't auto connect until I turn on the screen. My advanced wifi settings are below with basically nothing checked.
I agree this is a serious problem and for me I have no mobile network at home and depend on wifi and hangouts for voice calls.
Just curious what firmware is everyone on? Mine is 1.91.617.1.
This thread discusses it quite a bit, mentioning different settings changes to try.
http://forum.xda-developers.com/htc-10/help/wifi-issues-htc-10-weak-signal-fail-t3368165
I tried some of these changes, and things seemed better today for awhile, until I found out my phone actually wasn't getting the internet over the solid WiFi connection to my network. :/ I had to undo all the changes so I could get back online with it.
