[Q] WiFi connectivity issue - Galaxy Note II Q&A, Help & Troubleshooting

I have been using Note 2 N7100 running 4.1.1 for a week now but only a couple of days ago started experiencing WiFi connectivity issue at home. The problem I have is it would lose Internet connection and then disconnects from my wifi router. When I opened the wifi menu it says my router is not in range. Turned off wifi and then on again and it connected just fine. However, after a while I lose Internet connection again and then router connection as well. In addition, my PC and other mobile devices started having connection issues. So, I restart my router and everything seems to work normal again until I turn on wifi on my Note 2. The problem reoccured again until I decided to turn off wifi on my Note 2 and so far my wifi connection is stable. I did try to use static IP and for a moment it seemed to work fine yesterday but today it messed up again right after I got home and turned on wifi on my Note 2. I also reset my router to factory setting yesterday and I don't want to reset every day.
I remembered that I did a software update at work on my Note 2 two days ago but it's an update from Samsung. I forgot what the update was for. Is there any chance to undo this update just in case it caused the wifi problem but without having to root the phone?

try to add the ip and mac address of your note 2 into the router.

Internet Connection???

My Tilt 2 has been connecting to my Linksys router with no issues until yesterday. This was even after I flashed a new ROM. It has been painless until I lost my internet connection with AT&T and had to reboot my modem and my router. Since then I have been unable to connect at all. I have other wireless PC's that are connecting to my router with no problems. I have spent a lot of time going over and over the internet wi-fi settings. The phone is picking up the router, but never connects. I do not have any security running so this should not be it.
Any ideas?

[Q] HTC EVO 4G WiFi locks up since FreshEvo 4.1.1.0

I have an HTC EVO 4G running FreshEvo 4.1.1.0
The WiFi was working fine without a hitch until recently. It seems that since I upgraded to FreshEvo 4.1.1.0 and updated the radios with the patch, that this is when the problem started.
Now, the WiFi connection "locks up" intermittently and I have to reboot my TrendNet TEW-633GR router so that the phone will connect to it again at least for awhile.
The symptoms are: The WiFi connection with my home router will be fine for awhile. Then, it will not work.
I still get an IP address from the router and the WiFi settings says it's connected. But the connection doesn't work until I reboot the router. But the router isn't really the problem because other phones and my laptop can connect to the router even if the HTC cannot.
To the best as I can tell, the WiFi connection on the HTC locks up when:
A) I run the Roku Remote Control app and something unexpected happens like the app does a force close. The Roku Remote app uses Telnet, I believe.
B) I'm connected by WiFi at home, then leave and the phone switches to 3G. When I come back home, the WiFi between my phone and my router is locked up. However, if I connect to WiFi at another location, it works fine at the other location. Also, I can still connect to my home router with WiFi from my laptop or another phone.
Does anyone have this problem too, or a solution?
Thanks

I would have a go at flashing an alternative radio ROM onto the EVO first. This should be pretty simple if you've already changed ROMs and have a custom recovery.

[NEO] Strange wifi problem. Connects but no internet.

Hello. I have xperia neo for 1 week. It is great phone and great upgrade from my X8 but i see a strange wifi problem. My firmware is latest version - 4.0.A.2.368.
At my home phone connects fine to my wireless network and everything is stable. I do not see any disconnects, reboots or other problems. My router is linksys wrt320N and i connect at wireless N speed - 72Mbps.
When i try to connect to the wireless N network at my office the phone connects fine but i do not have internet access. I have IP assigned by the router, network is shown as connected but i do not have connectivity. I tried with 3 different browsers and with the market and nothing connects. At the same time i can connect with my laptop to the same network and i have internet. My colleagues with other phones also connect and have internet.
I tried setting static IP address on the phone but this did not help. I read that if i set static IP in router's settings assigned to the mac address of the phone this will help. Unfortunately i can not test this because i do not have access to router's settings. Also at my home i did not make such settings and everything is working fine.
Previously i have seen this problem with my X8 and the same work wifi network but it was not always present. It was present with some custom firmwares and not with others.
If you have any ideas or have seen this problem please help.
Having the same device from Globul I never had such problems for the 2 weeks I'm using it. I had some disconnects but i put the blame on my router.
if you can try changing the wifi channels
I think I've found the issue (by facing by myself)
The version neo is shippe (2.3.2) has a serious bug on AES encription.
Actually only the upgrade to 2.3.3 (no clue about upcoming 2.3.4) can fix the WPA/AES issue.
So the actual solutions are:
or change your wifi securty to WEP, updathe the phone via OTA
or use the Windows Software and update to 2.3.3.
Please note that if you use the Control Power widget it has been removed in 2.3.3
This was my problem when I had just bought my Arc.My phone couldn't surf the internet with my personal wifi network although I tried to use many browsers and also Android market. Then I reset and reinstalled my router, everything works well ^^
Ask your office IT staff to do a simple power cycle on the router and try connecting again. That may solve the problem.

WiFi stuck on Obtaining IP/Avoided Poor Connection

For some reason, my Wifi connectivity on my GNexus has gotten really bad lately. I'm trying to connect to my home router (Netgear WNDR3400), and it gets stuck on a loop at obtaining IP address then avoided poor connection and it keeps reseting back and forth. It only manages to connect maybe 20 mins in the day and it looses the connection again.
Reseting the router only fixes the problem momentarily then the next day it can't connect again. The router is working perfectly fine in my house w/ the computer and laptops. iPhone and HTC Thunderbolt are also perfectly fine.
What can I do to fix this?

Have you tried assigning a static ip address to the phone?
Also what type of network? My phone does it on a 802.1 wireless b network with identity security (individual uname and password to connect) Which is what my university uses... annoying it was, but i found out that foxfi was causeing the issue. But im assuming your home network isnt like that.
How do I assign a static IP to the phone?
My router is 802.11n. And it has network security, secured by WPA/WPA2 to be exact.
App called WiFi static will let you set a static IP within a dhcp network. You probably can do it through your router as well. I would read up on static vs dhcp if you have never set up a static IP before. Also you'll want to see what all of the clients ips are so you don't create a duplicate.

Is there another solution other than that?

Try to flash another Rom.I had the same issue with cm 10.1 based roms, but after flashing aokp based roms problem was solved.

Anyone having this issue on the Verizon stock ROM 4.2.2? I cannot connect to any wifi with DHCP. The only way I can connect is if I enter at static IP. I have tried about a half dozen access points with no luck. I have even done a complete phone wipe of data and tried reconnecting without logging into my google account to sync down my wifi settings. This pretty much prevents me from connecting to any public wifi hotspots unless I can guess their IP range. I have never had anything other than the stock ROM and OTA updates. Is there something somewhere I can clear or reset to fix this? It worked at one time long ago prior to jellybean I think.

wifi issues

Since I've purchased the note 10 +, I've had some wifi connection issues. The phone never stays connected, or will drop wifi frequently. Normally once a day. Now though, it is much more common, and it is for longer periods of time. I'll be casting something to my tv, and then the video will drop due to the phone trying to "reconnect" to the wifi. Has anyone else seen similar issues?
No issues here with WiFi. Do you have any other devices that exhibit this issue? What have you tried so far in terms of troubleshooting?
I've tried resetting the router, and doing a factory reset on the device. Also, I've tried it on another wifi network and it does it there as well. No other devices that I have on my wifi exhibit the same behaviour. I was hoping with a software update it would get better but it is getting worse.
Do you have a case on your phone?
Any settings made in advanced wifi settings?
Tried app like wifi analizer? Both to check the received wifi strength and also possible wifi congestion...
Are the problems only while casting to TV or also when streaming of Internet?
Did you try change in wifi settings in router, like extended lease time or assigning fixed ip-adresses to both TV and phone, change of wifi channel, switch between 2.4GHz and 5GHz?

The wifi network is fine. Both in signal and congestion. The phone is set to be on the 5 ghz. And I've never had any issues with it on any other device. I lose signal frequently. I only used the casting example to help people understand what's happening.
Now there is a problem with many routers. Even expensive models may not solve the problem with an Internet connection. I also had problems connecting to wi-fi. The phone was disconnected from the router once every few days. I called the guys who connected the Internet to me, but they said that everything was fine on their part. They sent me a master, he looked, but could not do anything except how to change my router. A few days later, I realized that the problem was not solved and started Googling the problem on the Internet. I came across a forum where they advised me to enter this ip 192.168.1.1 and after a couple of manipulations, I was able to fix my problem.

Are you just talking about the programming page of Netgear's routers? Netgear also has apps for that...

How did entering your router's default IP address fix your issue? What changes did you make to your router's configuration?
Just saying that you entered that IP address and making a couple of manipulations doesn't help the OP.
