why won't my internet work properly?

[Android Central Question]

I have got a Samsung tab 3 and for about the last 4 weeks the internet doesn't work correct. The internet works on my desktop but on my tablet sometimes it doesn't connect and other times it connects and comes up saying its connected but then when I try and use the internet it doesn't work, then sometimes it works ok. I have made sure wifi is on and even tried restarting my router e.t.c but this is a on and off problem, any ideas please? Thank you.

Welcome to Android Central! Does this only happen on your home wi-fi network, or on all networks (like public ones)?

Well I did take it with me the other day to wetherspoons and it didn't connect there either. So looks like all networks.

Does the problem still happen in Safe Mode? https://support.t-mobile.com/docs/DOC-27367

It works in safe mode.

Use it for a while in Safe Mode to make sure the same problem doesn't crop up after a while. If it doesn't, that means something you installed is causing the interference. Unfortunately, if you don't have any idea which app it might be, you'll have to go by trial and error, uninstalling apps one by one until the problem goes away.

Ok thank you for that, I will give it a go.

So in safe mode today, it says I am connected to the internet but I can not get onto youtube, facebook, or any other site I have tried. Seems to be different everyday?

Is this only happening at home? If so, try disabling IPv6 temporarily in your router settings. You could also try changing the DNS server: http://www.howtogeek.com/167533/the-ultimate-guide-to-changing-your-dns-server/

disabling IPv6 didn't work, I had no internet on my desktop or on my tablet then and the other thing you mentioned also didn't work

The only other thing I can suggest is to reinstall the firmware, in case it's become corrupt. You can try using Kies (http://forums.androidcentral.com/am...amsung-emergency-recovering-samsung-kies.html) or Odin (http://forums.androidcentral.com/am...w-flash-stock-rom-via-odin-new-interface.html). If that still doesn't work, then it might be a hardware issue, perhaps with the wi-fi radio.
