[Q] Wifi Blinking and phone restarting - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

N7000 When I click on pull-down menu , my wifi is blinking in and out , and my phone reboots it self at random . I was on 2.3.6 never had that problem I went to ics and it started doing that and it had poor battery performance so I went back , full wipe open europe but that error stayed with new GB . Any suggestions are welcome .

Try using an app like Wifi Static to configure your phone to use static IP on your wifi networks (as many of them as you possibly can) and see if that reduces your number of restarts.
The experience of a number of users indicates that random restarts on the SGN can be laid to rest by using Static IP based network configurations over DHCP.
It has to be worth a try for you.

[Q] Major wifi problem

I have a major problem with wifi on GingerDX & stock kernel, it drops the connection everytime it is idle, and it many times doesn't come back by itself or the statusbar shows it is connected, but there is no connection, and in these cases i have to switch it off and on. There is no encryption on the router. I set the wifi sleep policy to never. This doesn't happen on stock ROM. Any solution to this?

Set the WiFi sleep policy to "Never" to avoid WiFi going "ZZzzzzzz" when the phone is idle (lockscreen kicks in)
I mentioned that i already did that.
And it does it too when it is awake... i already downloaded many apps to keep the wifi awake but no success.
In this case it would rather seem you have a compatibility problem between the ROM and your Access Point / Router.
Try switching channels or secure your network to rule out your problem comes from tons of strangers using your wifi.
I think i switched channels before, and no success. The router doesn't accept connections from unregistered devices so even without password, nobody can connect from outside.

LOOOL ... MAC addresses are sniffed in a matter of split-seconds.
Anyway, since you are certain you already did everything in the book, and outside the book ... maybe try changing your WLAN cable past a new one.
There is no WLAN cable on the router, the antenna is connected directly to it. By the way 2 computers are connected through wifi and their connection is constant. But if it works on stock rom then there is something in the rom itself.
I suggest edit twilan.ini to make N standard work. This solved my wifi problems on SDE .
Search XDA for n standard on x8
Sent from my E15i using XDA
I'm gonna test it for some time, I will report back if it worked or not.
I have similar problem myself as well. I even upgrade it to latest rom and it still does that. I already set wifi sleep policy to NEVER yet the damn thing could randomly decide to cut off. As soon as I wake the phone up it will re-establish connection. Ever single time. Why does it not try to re-establish connection while the screen is off? The funny thing is that I have no idea when it drops connection. The logging has no time stamp that I could track down events.
I believe sincerely that there's still some bugs to be rid of
Try enabling N standard, since i enabled it the wifi stays connected, for now.
i had the same problem.. U just have to use nAa or Alfs for cm7 kernel and rom which works with these kernels and no problems anymore

LG Optimus 2X P990 - Service Problem

Hello,
Since a couple of weeks I've been having some issues with my beloved phone: the LG Optimus 2X Speed (P990) running the latest and greatest Cyanogenmod 7. And I was hoping that you could help me with that.
The Problem
My phone, and my previous phones have always had great service reception. I would never find my phone with two bars or less, unless it was brain-dead out of juice. I've always had the same provider (T-Mobile NL) and I've never experienced any problems with them.
However, in the last couple of weeks my phone can't find my network more often and often. I'd check my phone to see why I haven't gotten text-ed in the last minute or so, and it would be offline. Zero bars and status "No Service". At the beginning, I could put Airplane mode on, and then off again and it would reconnect. But since a couple of days that won't work either. I can put the telephone into airplane modus, but it gets stuck in it.
The button remains gray saying "Disabling Connections". If you go back, and into the Connection settings again the button can be pressed but indefinitely keeps the phone in airplane mode. The only way to enable connections again is to completely restart the phone. And as of lately I find myself having to reboot the device about 1-4 times a day.
Could you help me with this?

Obviously CM7 went a little crazy! I don`t think it`s hardvare problem and the most safe and secure thing u can do is to go back to stock rom and root and reflash CM7 again!!! Android is weird system and many weird things happen to many people. If u have few hours to spare u should begin there and see what happens. If that doesn`t solve your problem than u can start thinking about hardware failure (maybe SIM card, maybe phone antena). But i`m allmost positive it`s software isue. :good:
Disable the automatic date and time (network-provided one). See if that helps.
That was preventing my P990 from getting network at all after a cold boot.
Hi,
I have exactly the same problem. Disabling network-provided time helped (i.e. the phone connects to the network and data connection is up), but I was wondering if this is a bug and if there's a thread or a resource discussing this issue? Btw, the phone has been having some minor connectivity issues in CM 7.1 as well, but otherwise CM7 is useable.
Phone: LG-P990 (Optimus 2X), "Made in Korea" under the battery, does that mean for sure it's the SU660 flavour?
Carrier: Fido (Rogers Wireless), Canada
ROM: CM 10.1-20130722-UNOFFICIAL-p990 (tonyp build version 5) (Wiped and flashed on 2013.08.27)
Kernel: 2.6.39.4-kowalski-exp
Basebands tried: (none get me data connectivity)
LGP990hNAT-00-V25h-FID-CA-FEB-22-2012+0 (Original)
725 V10d (shows as Unknown in About Phone)
450 V20m SU660 (EDGE only)
OK, Correction...
Only the Wi-Fi connection was up. The cellular connection indicator was blue, which has led me to believe that cellular data connection was up as well. When Wi-Fi is disabled, the cellular connection indicator goes white and there's no data connectivity.
Furthermore, even though basic cellular connectivity was available for approx. 8 hours during the night, as soon as I left home and started moving it started dropping out. For example, I was only connected ~30% of the time for the past hour (and the reception along my usual route is normally great).
Toggling network-provided time doesn't seem to have an effect now, but the old tricks (toggling cellular connection, going into Airplane Mode, rebooting phone) seem to restore cellular connection for a brief period.
I also noticed that often when I would launch a data-using application (Internet browser, gmail app) cellular connectivity would be lost in a minute or so (saying No Service).
I've tried looking into "logcat -b radio" for ideas, but I don't quite understand what's happening here (willing to learn though).
Help...
I have installed CM7.2 (official CM) and CM10.1 (tonyp 5, oldbl) with dual boot and can now switch between the two ROMs. I have good cellular and data connectivity in CM7.2, but no data connectivity even after a fresh install of CM10.1.
I assume the baseband has nothing to do with this since both ROMs are using the same.
So, armed with a dual boot device, the n00b is ready to do troubleshooting! It only needs guidance now... Help?

Weak network on stock non rooted firmware. What could be the reason. Please help.

Hi guys.
In the past I have switched many custom fw from CM to slim beam and tried almost every custom TW firmware out on this forum.
Have even used stock fw with philz and speedmod kernel from time to time.
I am currently on non rooted stock 4.1.2 India. My phone is almost 15 months old.
Now I face weak network coverage (network keeps on fluctuating from 4 to 2 or 1 bar, generally only 2). And I face frequent wifi disconnection though wifi device link being stable, my phone stops transferring data for few seconds (say 20-25 sec) and then rework. This happens say every 15-20 min.
Regarding weak network I even replaced my sim but still same issue.
Any help that I can expect.
Regards
Mani
modem, experiment with those, if you dont mind warrantee, otherwise go service centre
Whats the modem on the phone? Make sure its close to the region DDLS6 is the latest for India.. you can also use ZCLSD chinese.
for Wifi, its mainly kernel related but the kernels you tried as working perfect.. so try to change the Router wifi settings to b/g and in phones advance wifi settings give a static IP.. see what happens

[Problem] WiFi periodically hangs and signal strength drops

Hi, all, I'm having an issue with Wifi connectivity that presents itself mostly in Play Store and sometimes during browsing with stock browser.
Quite often when trying to install something from the Store, the moment i hit Install button, screen pauses for a few seconds, wifi strength indicator drops one bar and there's a notification that the connection was lost. Stock browser also loses conection and requires reloading, latest Opera does not (at least, I didn't experience it). This happens very frequently and multiple times in a row, especially installing from PS where I have to wait for the notification to show up, then hit back button and try to install again, sometimes several times before it succeeds. Also, I've downloaded Firefox, same problems as with stock browser.
I'm on official V20a 4.1.2, Play Store is v4.1.10, fewer than 15 apps installed and not all require data connection. Option to keep wifi connection active when screen goes off is enabled. I have an 802.11g router about 1 meter (3 ft) from the phone and the signal registers as strong (full 56 mbps). Abolutely nothing and no-one else is utilizing the connection at times. My other desktop PC via ethernet cable and my other wifi phone have none of these problems and the line was tested several times.
Even though I did spend few days with official V10 ICS 4.0.3, I don't recall having any of these problems.
Also, wifi indicator in the notification area dissappears after a period of innactivity, but power toggles show the wifi is turned on. Is this normal (this is my first long-term android phone, I'm not that familiar with the OS)?
Is there a solution that doesn't require downgrading to ICS or custom ROMs?
A side-quiestion: how to update play store part from downloadig .apk from some webpage? Is there an autoupdate option somewhere?
After some tinkering with router options, I no longer seem to experience the described problems. I believe that lowering the DTIM value resolved the issues.

Note 5 Wifi Turning On/Off Intermittently

Hi,
My Note 5 (SM--N920W) recently started to switch Wifi, on/off intermittently. Sometimes, the Wifi stays on for 15/20 minutes (like when watching youtube) and some time it turns on/off continuously (mostly, when downloading a large file with a continuous stream of data). I can see that in the phone settings, the Wifi button goes grey (to off position automatically) and turns blue automatically & tries to connect to the router, sometimes it stays connected for some minutes and sometimes it's just instantaneous that it goes grey again (Wifi off). This keeps on repeating.
The phone is updated to Android 7 (official ROM) and has been reset and also tried all different settings like turning off location completely, disabling wifi scanning etc but that didn't help. Any idea what could be wrong? Also, the phone is locked to a carrier for which I don't have the sim anymore. I am not sure if running it without sim is causing this wifi issue.
Thanks! Any help is highly appreciated!
If you can try using a different wireless router or network, and see if the issue persists. I had a similar problem awhile back, except it only happened when Bluetooth was on. I ended up buying a new router instead of the one I was using from Comcast, and it resolved the problem! Also I've similar issues with other devices, and editing the build prop and changing ro.securestorage.support=true to false in /system/build.prop might help.

Thanks a lot for the reply. I'll look into secure storage flag, though it looks like this is for the rooted devices, mine does not seem to be rooted (I bought it online, not sure if that was rooted earlier or not).
Another behavior I have noted, that initially the wifi for first few minutes works ok, no drops or switching on/off. But then it starts to go nuts turning on/off continuously. I am not sure if its a hardware issue, that somehow the wifi module gets hot after a few minutes of usage and starts to malfunction. But I have read somewhere on this forum, that the BT & WIFI are on the same module on the motherboard if the BT runs fine (which it does on my Note5), WIFI as far as hardware is concerned should be OK.
I haven't tried any custom ROM (though tried downgrading to Android 6.1 - ROM from sam mobile) but that didn't work. Any idea, which custom ROM is most stable and easy to apply?
Thanks!
If your on a stock unrooted rom, I'd definitely try another router, even if your just connecting to a friend's. If it doesn't occur then, its the router. As far as custom roms, I'm running the Note fan edition port by RadeonMaya, and it works great.
