Galaxy S6 Edge Wifi issues w/Marshmallow

[Brian V Blake]

Updated to Marshmallow. Over Wifi, cant connect to the internet or anything app related that uses the Internet. Wifi basically unusable and constantly need to turn it off to do almost anything. Have tried all fixes and searched forums. Had no issues prior to the update. Anyone have any ideas?
Signed: the data hogger now that im constantly on data...pissed!

Same here except I can access all apps that are not part of Google. Google Play, Maps, Earth, etc. cannot be accessed via wi-fi. They can be accessed via data though. It started yesterday after my Marshmallow update on Verizon.

If you are willing to try something fairly quick, simple, and easily reversible, disable IPv6 on your LAN's DHCP server.

Restart your phone, connect to your Wi-Fi, confirm that you've only been allocated an IPv4 address, and see if the problem persists.

If it doesn't change the issue, you're out about 90 seconds of effort to put things back the way they were.

I found the answer for mine. If you have a Belkin router go into the settings and and disable the Intellistream option. As soon as I did that and restarted the router it worked like a charm. I had restarted the router previously several times with no luck until I disabled the Intellistream.
