[Q] WiFi Problem

[Paulx777]

Out of the blue, my WiFi stopped working. I know occasionally this happens and is usually fixed by simply turning WiFi off then on again our by unplugging the router for about ten seconds, but neither of these methods is working this time. This is different, I'm stumped. (By the way I have the SM-P600)

So, the error message I'm getting is, "failed to obtain IP address", then if I click, "RETRY" I get an error message that says, "Network disabled because internet connection is too slow." Which doesn't make sense because all my other devices on my WiFi network have no problems connecting and have no speed issues.

Really, really frustrating. Any help would really be appreciated! Thanks!

The same problems occurs frequently with my tab P-601.
But I have to restart the tab and it works fine. I have to use mobile data for internet connection instead of wifi.
I appreciate any help.

Anybody else have this happen?

I haven't had this problem on my P600, but have had something like it happen on other devices. I think the issue is that Android will remember and avoid WiFi APs with a poor signal. When I am on the fringe of my home WiFi the signal is weak and my network gets blacklisted. To clear the blacklisting I have to force the device to forget the network, the connect again as a new network.

Couldn't detect WIFI

I updated the Android 4.4.2 and since then my tablet couldn't find my WIFI.

My phone and my computer found the network normally but my tablet just showed some of my neihbors' networks. I tried to restart the tablet and reset the router but didn't help.
Now I tried changing he router's settings through my computer and set the frequency to a higher value and now my tablet finds and connects to the WIFI normally!
