I recently flashed on cm7 on my aria. it is great but my data usage began shooting up. i realized it was due to the fact that everytime i lock my phone, it disables my wifi (i saw this because everytime i unlock im on 3g for a 1-2 seconds then i get on wifi so that means that the whole time my phone is locked it uses 3g data ) is there anyway i can prevent this from occurring??
Thanks,
Okachowwa
Menu -> settings -> wireless & networks -> wi-fi settings -> menu -> advanced -> wi-fi sleep policy -> never
I think that's it.

Have you checked the Wifi Settings to see which sleep option is selected? There is an 'Never' option which tells wifi to stay on even when the phone sleeps.
One thing I noticed its that if I leave my house I have to turn off wifi and turn it back on to find my router.

yup...that's why you just turn your wifi off with the notification widget (very simple and painless might I add) if you know you're leaving the house...what's the point of having wifi enabled if you're not in range of your network? all it's going to do is drain your battery. i left my wifi enabled one day when i sent to work and within half the day i had ~12% battery life...definitely not good practice to leave it enabled that's my 2 cents, do as you wish though. to each his own.

Yup, I have the same issue with CM7 nightlies. This worked flawlessly in CM6 and stock2.1. So far there isn't a viable solution.
from the CM6.1.1 thread...
Q. How do I keep my wifi from going to sleep every time the screen shuts off?
A. There is a hidden feature that disables wifi sleep.
menu > Settings > Wireless & networks > wifi settings > menu (again) > advanced > Wi-Fi Sleep policy > Never > menu > Save
However: although you can keep the wifi service from sleeping, the wifi driver will still sleep on it's own after detecting no bus activity for a period of time.

I've made sure to set Wifi Sleep Policy to "Never" but that did not fix my wifi problems. What I see when I open Wifi Settings is a cycle of:
Code:
Scanning --> Connecting --> Disconnected... Scanning, etc
When I look in logcat it shows it attemping (in vain) to authenticate against the last wifi network I was using -- even though it is no longer in range (and clear across town). In a nutshell it is refusing to recognize the actual nearby network UNTIL I toggle wifi settings.
I've had the same behavior on FR008 and the stock ATT 2.1 load as well. When Wifi is in that on but not really connected state some apps can wake it up...the default browser usually will, but Listen would not. I just gave up and only turn on wifi when I need it.

What is the point of having wifi set to ON when you are not in range of a network? Hence why, if you are using CM7 or CM6, you should utilize the notification widget and turn wifi off if you know you're leaving the area of your network. It's simple. Things aren't ALWAYS going to work how YOU want them to work. Thing will not always be automatic. I think I quote attn1 when I say this, just because it doesn't work how you want it to work, does not mean it is broken.

Well, just because people don't work exactly like you work, does not mean they are doing it wrong. If something is broken I'm going to call it out. I might be incorrect, but let's be clear: you aren't questioning that wifi in CM7 isn't working the way it did in CM6, you are questioning my behavior -- which is a weak argument.
I guess you don't understand the issue, so I'll spell it out:
Wifi worked flawlessly and automatically for me in stock 2.1 AND CM6. This automatic behavior does not work in CM7. Manually toggling something that simply "just worked" before is a regression, not a feature. Hence the reason I point it out -- the devs can't fix something unless they know it's broken, and I seriously doubt the devs are able to test all/every permutation. I have nothing but respect for the work they do, thus my very respectful tones in my earlier posts. I've had no indication that the devs are unwilling to get feedback about their work.
You asked a question though, and here is the answer:
I leave Wifi on all the time because I'm a consultant -- I work in many different locations throughout the week, travelling the country. I have dozens of wifi networks saved on my phone, and it is useful for me to have my phone automatically jump on the correct, nearest network. I'd rather use free wifi instead of paying AT&T for data charges. It is not always possible for me to remember I'm in a location with a known wifi network, or to remember to manually toggle wifi settings: it is useful for me to have this happen in the background. Sometimes I'm on a call, sometimes I'm heading into a meeting and I'd rather not mess with my phone. I want wifi to be on all time, scanning for the correct network, and jumping on it when it's in range.
Outrageous, right?! Not actually -- this is the existing behavior in CM6 and stock 2.1. From my standpoint, wifi just worked -- I didn't have to think about it, didn't have to manually toggle something to prevent AT&T data charges.
This is desired behavior for me, and I'm happy with rolling back to CM6 to get it. I understand that _you_ don't need this behavior, but that doesn't mean it's wrong. It just means the world is bigger than you realized.
And yes: wifi in CM7 (beta) is currently broken. Read the threads. Many people are having problems with it.

That's a good tip, I feel kind of dumb for not thinking about it lol and I also agree that it is good practice to do so. I just wanted to point it out in case a dev was going through this thread which is relevant to the topic.

fyi CM6 & 2.1 != CM7. Your argument is null & void.
Also, being a "consultant" and the very important man you are, flashing a rom that's not even in beta stages yet probably isn't the best idea you've ever had.

Why do you remind us that the rom is in a beta stage? "Beta" implies it is not fully functional, but your argument all along has been that it works perfectly....
Look, it's clear you haven't actually understood any of my posts. I'm highlighting error messages or erratic behavior I see in logcat running CM7. I've posted what I've seen so the devs can take action, or not, as they choose. Since you aren't in that audience I don't understand what your beef is.

That being said. Beta does NOT necessarily imply that thing are not fully functioning, it simply implies that it hasn't been put into RC or stable. You can have a fully functioning beta program. HOWEVER, it may not be working properly. But creating a thread about an issue that's been brought up 20+ times now is pointless. I'm PRETTY sure the devs know about the issue, should it actually be an issue. Now that I just wasted another 15 seconds of my life, i'm going to casually /part from this thread and I'll end my post with this quote again, in case you didn't catch it the first time.

If you are not having such luck, then you need to look at your access point if you have already wiped data.
Really, the constant carping about wifi is absolutely pointless.

1) Because Google Maps uses known wifi hotspots to help establish your location.
2) So that you don't have to keep toggling wifi on and off when moving between hotspots (or home and work, for example).
3) To use the network notification feature (aka "notify me when an open network is available").
HTH
Edit: seems to be fixed in RC3!

i have try everything and still same issues with wifi. and i change the radio ( baseband ). still i am thinking of uninstalling it bc i dont have wifi
Sorry to tell you but that was with the old wifi stuff (every nightly up to build 25), which I had no problem with. The RC/nightlies have new wifi data made by jznomoney, which I have on and off problems with. Its working for most people but there are a handful who are having problems. I flashed ladios' kernel and my wifi is doing a lot better with the new RC/nightlies.
Signatures are fancy.

I've noticed something similar with CM7 on my Aria. When I leave the house and come back it doesn't always connect automatically and it will enter into this cycle of scanning, connecting, disconnected.
I had to reboot the phone to get it to stop the cycle and stay connected. I don't use a lot of data anyway but I still prefer to use wifi when available. Interestingly just now it wouldn't even see any of my neighbor's wifi networks at all which is odd.
EDIT: This issue appears to have been solved. the newest ril2 and a recent radio for your CDMA handset should do the trick. Thanks muzling, arrrggh and hyc.
The bug seems to vary for people. My signal pretends to be lost after each call, and sometimes after texts. It will still receive calls, but I have to toggle airplane mode if I want to call out or text out.
I don't make many calls so the bug hasn't bothered me much, but I had to make a bunch of calls today while on the road, so toggling airplane mode after each one actually got on my nerves a little. I was going to ask if there were any tasker users here to try out some things, but apparently tasker offers a 7 day trial straight from their site, so I decided to try it out. It crashed on its first run, but seems to be running fine now on FRX07.
It took a few tries, but it seems to be working with this combo.
Profile 1: context -> application -> phone; task-> variable-> Set Variable -> %CALL to 1
Profile 2: context -> application -> phone (NOT); task-> variable -> Set Variable -> %CALL to 0
Profile 3: context -> state -> variable -> %CELLSRV matches "noservice"; task -> Phone -> Radio -> Toggle (if %CALL matches 0); task 2 -> Phone -> Radio -> Toggle (if %CALL matches 0)
My first try had the phone hanging up on me during a call. I figured maybe the phone was reporting no signal before the hangup, so I added profiles 1 and 2 and the user var %CALL to limit the radio toggle to when the phone app wasn't in the forefront. For now at least, it seems to reconnect within a couple of seconds of hanging up. Color me happy.
Links of interest:
Quick tour of avail contexts and actions || User Guide
My next task is figuring out a way to toggle the speaker when I first dial out. It always spits some fuzz when I begin outgoing calls unless I toggle the speakerphone on and off. I haven't found an appropriate context yet (application -> phone would toggle unnecessarily for incoming calls as well, not sure if %SPHONE would detect the speakerphone as being on during the bug), but hope springs eternal.
Interesting solution...
I would much rather figure out the root cause (with a fix in theory to follow), but in the meantime anything to help with sanity is always welcome. Kudos.
Thanks. Root causes are definitely the way to go, I'm just not smart enough to aid and assist on that level. Noticed enough complaints about signal loss, I thought some others might benefit from the profiles.
Tasker is no mortscript, but it seems the closest android analog. I used to kind of enjoy scripting away at winmo's faults, and hope I might be able to smooth some rough edges in my android experience too.
Thanks... I just installed Tasker and added the profiles as you said and will report back if it helps me with the signal loss.
Would you mind telling me why you put the same task twice in the last profile? Thanks

The first toggle turns off the cell radio, the second turns it back on.
After several days of trials, I ran into an instance (when my phone was a little laggy anyway) where it was endlessly turning on and off, apparently because it was detecting noservice multiple times before the toggle was complete. I haven't done this yet, but adding a several second delay into the mix should prevent loops.
Hope it helps!
signal loss?
signal icon show no signal or signal strength zero level?
Which radio version you use?
I dunno, no signal or no service (incoming stuff still works though), I think it's a little x where the signal bars would be. It's a common enough issue, see the FRX07 thread. I'm using whatever radio is bundled with FRX07.

I think he means radio firmware - it's flashed in bootloader mode, and usually comes with stock ROM's... Basically it's completely independent of our Android port.
I'm curious, did you try hyc's updated RIL? There was a slight bug that seems to be helping all sorts of issues, it was related to incoming calls...

I encouted the same problem with you when use an special radio, try to use newest radio ( http://forum.ppcgeeks.com/cdma-tp2-...10-rhodium_w-radio-roms-mirrors-included.html )
You can upload your ril's logs,use command "adb logcat -b radio",when signal icon show x, there must be an error like "system need return success, but ril return fail"
It's late, goodnight.
Thanks guys, newest vzw radio and newest ril fixed it.

Try to switch the encryption and see if that fixes it. If it does then this will be a confirmed issue.
I am here to learn.Thanks for sharing.
Ok it's been about 10 mins without a single drop...seems to have corrected the issue. I was using WPA-PSK [TKIP+AES] and I switched to just TKIP. I'll check back in a bit and let you know after about an hour or so. I'll try it using just AES then switch back to TKIP+AES and I will also try on 5gHz bandwidth.

Glad to see that it worked. Let me know and I'll post it up as a workaround for the time being.
Ok so it seems that the only WiFi issue I'm experiencing stems from using duel encryptions. It works fine using WAP2-PSK [AES] alone. WPA-PSK [TKIP] works fine alone as well. I played around with the settings for a bit but I couldn't seem to get it to work properly on duel encryption.

WIFI Disconnect/Reconnect Issue
Here's the issue I've been having. I'm in a very active wifi neighborhood. Even though I had the advanced wifi set to 'Always on' it kept disconnecting (and instantly reconnecting) to my network. The phone is scanning the neighborhood almost every 15 seconds. It's simply WPA-2 with just AES (and I'm not changing to TKIP)
This is a problem for me as I use "WiFI Unlock" to keep from having to enter my PIN when I'm at work/home and "Home Sweet Home" which uploads any photos I have taken to my server when it detects the home wifi network (and deletes them from my phone after 3 months).
Anyway, I was just on the chat with Samsung and in the end we did this,
1. disable the ATT WIFI auto login function (seems there's something similar on the Sprint phones that's a issue).
2. soft reboot the phone (turn off, pull battery, count to 30, boot up)
However this suggested solution doesn't work.
The wifi isn't staying connected though the breaks are very very temporary, but long enough for those apps to kick in.
Update additional things tried:
3. Turned off WiFi power save in the *#0011# service menu
4. Turned off Open WiFi notifications
5. Selected a single wifi band (5Ghz) where there is ONLY one network, mine
FWIW, I like that it connects to my 5Ghz wifi at 150 mbps, the speed is great.

Yeah this is the same issue. I tried turning off sprint auto connection feature and also dialing *#0011# menu> WiFi> and disabling WiFi power save mode. But either of those had no effect after I had rebooted the phone. Maybe you should give it a try, it seems we have the same problem but with different encryptions.

Are you restoring a backup from an HTC device or perhaps a backup from a Froyo device?

Nope; OG Epic - was running GB 2.3.6 Thunderhawk 5.1
(I ran CM9 as well on it and always restored my logs and sms/mms)

I had hope for a few minutes that this would work ( *#0011# ) but it's the constant rescanning for networks.... since so many wifi in my 'hood have the channels set to auto, they're constantly changing as they compete for space. This is why I wanted a phone with 5Gh- I even set it to only use the 5Ghz* but that doesn't do it either even though I can only see ONE network with 5Ghz, mine. this phone is constantly scanning and every few scans reconnecting.
turning off the AutoNotify of open wifi doesn't help either.
It's a plot to make you use more data on the carrier's network!
*which is bad for me, since I rely on wifi which is mostly 2.4Ghz when I'm out of the house (may need some NFC tags for the car or house doors.

Brett so you are still getting wifi issues and the dual encryption off just made it disconnect less?

WIFI Disconnect/Reconnect Issue - Level 3 report
FWIW. I just got off a 45 minute call with Samsung Help Support, went to level 3 support in Texas. This is newly documented, I've referenced this forum for additional reports of the dual encryption and the wifi connnect/reconnect issue I'm having. My ticket # 2113584507 (just for disconnect/reconnect) which you can mention at level 1 as having the same disconnect/connect issue. I specifically asked if I could post the ticket # so anyone could reference it at Level 1, but they will still take your own experience down.
Level 3 said they expect that they will be getting calls today since it's the first full day after the release. So if you want it fixed, CALL SAMSUNG, they're collecting bug reports.

No none what so ever...after I changed the encryption yesterday I haven't had one drop in the last 14 hours.

I use a lot of internet sharing (wireless). I noticed that when I start charging battery my phone is dropping signal network after a while. When I switch the screen back on, signal comes back. it's very annoying and it doesn't happen when phone is not charging. At first I thought its rom/kernel/modem related but problem remains with different combinationsb of above.
Any suggestions on how to fix this issue?
Do your RIL and Baseband match?

I guess so. Usually I use modem provided with rom. It looks like phone was going to deep deep sleep that it even loses network service and it wakes up when screen turns on. But as I said it happenes only when charging and, I think, only when I use internet sharing.
edit:
just checked with getril app and it says unknown ril so cant really tell if they match. I've put a NEAT rom 3.5 just today and didn't have chance to check wheather it still there or not but i guess it will still be there.
Your RIL and modem can change. The modem is up to the rom maker, they decide which one to use wheras your RIL stays the same from what you had on stock rom, unless you changed it of course

First of all, sorry for asking the same question twice (http://forum.xda-developers.com/showthread.php?t=1489237), but this thread seems to describe my problem even better.
I am using the latest Cyanogenmod 10 nightly on my Galaxy i9100, and it appears as if I have a similar problem. When I start charging my battery, the signal usually drops after a while. This is quite annoying, because I use my phone as WLAN hotspot. Rebooting the phone (charger connected) does not solve the problem. Instead, I usually have to unplug the cable and after that the phone quickly picks up a signal again.. I also tried to switch the airplane mode on/off. But then I cannot switch the airplane mode off again, so something really seems to be hanging. In these situations, the baseband version shows 'unknown'.
I have just used the app GetRil to confirm that the Ril and baseband version are matching.
Has anybody solved this problem? Is this a hardware or software issue? Are there any things I could test or should I provide more information?
Thanks a lot in advance!

Guys' though I've never experienced this issue with wi-fi hotspot, I do know why the wifi turns off when your phone is charging.
So to settings > wifi> press menu button> choose advanced
you'll see an option what says "keep wifi on during sleep" or something of sorts. The default is set to "never". You guys need to change it to "always".
Cheers

Sorry for the confusion, but I think you got me wrong. It is not the WLAN connection that drops. It is the mobile network connection that drops, so I cannot make/receive calls or use the 3G connection anymore.
Update:
Didn't find solution, flashed back sammy stock rom with custom kernel and all problems vanished. Using stock rom since than and never had this problem again.

Just for the records: I could also solve this issue by flashing a stock rom again. This must be a problem of Cyanogenmod.

I had this problem too and all I had to do was turn off fast charging in the settings
I think it turns off or lowers the strength of the network so it could charge faster and that's why it does this
I don't know much about tech so it might only help with my phone ( which is the Samsung a12 ) but I also hope it helps you too
Good luck
Firstly an introduction to my problem - I've been having problems with high cpu usage whenever I enable my wifi. I've gone to stock [I9100DXLSD_I9100OLBLSD_XME.zip], tried different kernels [Apolo, siyah, speedmod, dorimanx], tried different roms [slimkat, neatmod, jellysnap], done factory resets for each, flashed quite a few modems [dx's,xx's, currently trying radio-cm-9-SGS2-LP6-signed.zip, there's a whole bunch that I'm still going through as well - can't post urls yet]. I had no luck with all of these methods so far.
Since that approach didn't work I have also been looking at wakelock detector,gsam and betterbatterystats to find out what was chewing up cpu and causing battery drain. I initially thought it was something caused by google play services (SystemUpdateService), wlan_rx_wake, or a pc/router on network with a configuration conflict or something like ipv6 causing bizarre behaviour but so far I have been able to get rid of wlan_rx_wake problems but those were minor on the battery drain problems I was having. Using a static ip also did not improve anything. Wakelock detector/gsam/betterbatterystats were now all showing either android os or android kernel as the culprit but would not show exactly what process was causing it. Once I enabled 'show cpu usage' in developer options I was able to see that dhd_dpc process was causing all this havoc. There does not seem to be much information on the net about this process and problem. When I switch wifi on, I'll be able to use the net fine for a few seconds to a minute before dhd_dpc decides to kick in and using a high amount of cpu causing insane drains and I have to quickly switch wifi off before it locks up requiring a reboot.
What I have found out through all of this by accident is that if I enable wifi and then quickly copy a file from my phone to a pc on the network, I am able to use internet on my phone without any lockups and the speed (cpu) is fine and fluid as usual but only while the file is still copying over the network. During this time dhd_dpc seems to consume cpu like it normally should as I've seen on the other devices I have. Why is this? This has to be a software issue since it works flawless when I do this? Not sure why it would require some sort of lan traffic in order to get wan traffic working without sending the cpu usage to orbit. The battery of course drains but not as bad since it's busy copying files over. Maybe possible that it doesn't like the routers on my network that might be sending arps and copying files over the network makes it ignore that traffic (just shooting in the dark here)?
I hope someone can shed light on this and perhaps give me some other things I can try. Btw, cell radio/mobile data are all fine, except for one or two of the modems that I tried. So is this kernel, rom or modem related? Please help! This is the only thing not working properly on this phone. Thanks for all those that took the time to read and answer.
Currently on my phone:
Rom: I9100XWMS3_NeatROM_v6.4
Kernel: Apolo-4.15b_Regular
Modem: LP6 (this is just what I am currently testing out of the dozens of modems I have)
PS- yes I use kernel wipe and rom wipe scripts. Maybe the problem is somewhere in dhd.ko?
Anyone mind uploading their dhd.ko that doesn't have this dreaded dhd_dpc cpu pegging purge business just so I can rule it out?
