Data connection wifi connection stops - Galaxy Tab General

My tab was working fine for first few days but now data/wifi stops for no apparent reason. Ive flashed JJ4 rom but problem still occurs. Anyone else experience this and is there a solution?

You may have the same WiFi connection problem as I do (Tab continuously trying to get an IP address).
Go for a Static IP address.
If not Hard Reset until next occurrence....

I dont think it is that because my network data doesnt connect either when i trun off wifi. Must be faulty, to be returned.

Frequent Disconnecting from WiFi?

Is anyone else having trouble with their WiFi dropping out all the time? My phone keeps dropping WiFi, dropping back to 3G. I have to keep going to settings and telling it to reconnect.
I have a Linksys WRT54GL running Tomato firmware. Most things can connect to it just fine, but my Dell Laptop from work gives me a BSOD when I try to connect it wirelessly.
Thoughts?
I think I figured it out. I upgraded my Tomato firmware on the router, and WiFi seems to be working much better.

Please post back if it acts up again. My wifi has stopped working a few times and I had to manually reset it. My problem was compounded because 3g seemed to be active but webpages would timeout and sync would fail. Really annoying.
no problems with my wifi but I turn off network data. Maybe that helps?

I have the same issue. My wi-fi goes down and keeps looping through "obtaining an IP address". Killed my battery last night trying to connect to wi-fi. I can't get it coinnected again until I reset my router. weird?
I don't know if I would classify it as constant, but the University wireless network disconnects after some period of inactivity. I'm not certain if it is due to the phone or the network.

It seems like it is still doing it, but I'm wondering if what it is actually doing now is disconnecting after a period of disuse, then reconnecting.
It seems like if I don't see the WiFi symbol, and I select Mail or the Browser, it will re-appear.
I have similar issues with WIFI. It seems having a hard time connecting or even seeing the signal at times, but other times it's fine. I have WIFI at home and at work, and many places I am so I use it all the time, and all of them I have set up (I'm a sys admin).
I have WiFi analizer loaded and at times it won't even see my netowrks when my laptop is already connected. If I reboot the phone it seems to fix it after a min or so. Sometimes turning WiFi off and on helps but not always.
It's really inconsistant... I'll go a few days with no problems, then it will have problems for a day or so. Open or encrypted don't seem to make a differance.

Tomato firmware, that sounds cute.

Issue 1040: wifi does not timeout on idle
Issue that was in an earlier version of Android, and is back in 2.1.
When the phone sleeps, it turns off WiFi. Then, it won't turn it back on properly until you go to settings or sometimes WiFi settings. Then it just pops on automatically.
Yup, I got this problem too and its very annoying.
It usually happens when the phone has been sleeping for an extended period of time. Sometimes wifi disconnects and will not reconnect even when I'm in the middle of browsing the web.
i had this issue as well.... i went to settings/wireless and networks/wifi settings....then hit menu/advanced/wifi sleep policy.... i selected nver and haven't had a problem since
Problem is, "never" is already selected and issue still persists.
I had set it to 15 minutes to see if it fixed the problem, because I was having it when it was set to never. I'm setting it to never now to see if
the GUI just wasn't displaying the value that was set.

Delay in connecting to Wifi after GB upgrade

This issue really bothers me a lot after I upgrade my Atrix to Gingerbread: when I turn on the wifi, it takes up to 2 minutes for the phone to connect to a wifi hotspot. During that connecting time, in the phone's wifi connection settings, it's either showing 'scanning' or 'obtaining ip address' but with an empty wifi network list. It seems like the wifi chip is still initializing itself or something. This problem doesn't happen all the time. About 1 in 10 times, it can connect to the same wifi hotspot instantaneously. And I am pretty sure it's not the problem of the wifi hotspots because I used them before with the same phone + froyo and there was zero problem at then.
Has anyone seen similar problem like this?
Forgot to mention that I have done the factory reset several times and the problem never goes away.

[Q] Wi-Fi not working from one day to the next..

Hi Community!
I have a short question for you.
How is it possible i can't connect to my wifi network at home from one day to the next? With my Nokia 5800 i can connect without any problems.
And at work i can connect to wifi with my HD2, too. Only at home i cant connect anymore. I tried resetting my router, changing the securtiy settings, channel, ssid. nothing helped. I tried setting up a static ip instead of using dhcp, but no chance. No mac filter or anything else is active. Tried to reinstall the rom several times, but as suspected it didnt work.
Like i said my nokia works at home connecting to wifi. So the error shouldnt be by my router. And since the HD2 to connects at work to wifi it also shouldnt be a problem of my hd2 :F
Always telling me "Optaining IP-Adress", so it wants to connect, password is typed in correctly, but something prevents it connecting. Usually it connects immediatly after searching for an ip adress.
So, from one day to the next wifi isnt working only at home..
Do any of you have a clue what's going wrong here?
another restart of my router solved the problem... dont ask me why.

Galaxy S5 DNS Issue

In the past week my Galaxy S5 (SM-G900V - Android version 5, Kernal 3.4.0) has lost the ability to connect to the internet a few times when wifi is on (under wifi, it appears that it is connected successfully to the wifi but when using the internet I get an error message about DNS not working).
This first time it happened was at at home and I thought that maybe my router just needed to be reset (which didn't fix the issue) but it happened at work today.
Both at home and at work, the only thing that I could do to fix the issue was restarting the phone (resolved the issue at both locations).
I tried all of the following suggestions with no luck:
Turning wifi off and then back on
Making sure that 'Always allow scanning' and 'Smart network switch' were both turned off on my phone
Choosing the wifi network on the phone and 'forgetting' it and then connecting to it fresh
Setting the DNS servers on the wifi network of the phone to use a static IP address and static Google DNS servers
Trying a different browser on the phone
The only thing that has resolved the issue once it starts is to restart the phone.
Any other suggestions?

Wifi on Lolipop 5.0 G870A will not connect

For the last week or two I have been unable to connect my phone to wifi networks.
At first the problem would be that I was getting disconnected from any wifi network I joined, now I can't connect at all.
The wifi networks page sometimes (not always) does not detect a strong network even if I am standing a few feet away and the phone has previously connected and other APs are connected and working like my pc
If I try to connect then I get the "Connecting" status followed by "Saved,secured"
I have searched the internet looking for a fix to this and tried wiping the cache partition, forgetting the network, airplane mode toggling on and off, apps that wipe the known network list and some others including lastly a factory reset on the phone but nothing seems to remedy the issue.
From the wifi router I have tried using an unencrypted (open) connection
Now I think I may also be having problems with the bluetooth connecting in the car but I haven't had a chance to really investigate that one yet and it may or may not be related to the last factory reset.
My phone is not rooted.
Build no. LRX21T.G870AUCU2B0F3
kernel3.4.0-4443965

Can anyone offer any assistance to my current issue ?

I have just confirmed that the Bluetooth in my car is not detecting my phone when it scans (the phone bt is switch on and the visible box being checked) so that's both radios with similar issues.

Im having same issue with wifi... sm-g900r4
I just stumbled on a clue, while using an app called 'wifi cleaner' there is a feature allowing you connect to wifi networks within the app. I type in the password, authenticating is shown on the screen followed by "incorrect password".
I know the password to be correct..
Mmm

I was wondering if you ever got this issue fixed?
I thought I had but the problem comes back in a different way.
Sometimes wifi connects but only connects at 5 mbps.
Now wifi will not turn on at all. ( radio button is greyed in settings)
I did find a thread on xda where some Motorola users were having the wifi off issue and it was due to a missing system file which could be replaced on a rooted device. However I don't have root on my s5 g870a and it's not likely I can get it.
