Contact TP-LINK support team here and report the problem. Maybe they know the problem but cannot reproduce it. If more and more users report it, they may pay more attention to it. How do you think?...

I know that 141008 is newer than 140613 and I didn't suggest to upgrade the latest firmware. Maybe the word "upgrade" caused misunderstanding. Since MrNice wants to change the region but cannot, you...

Maybe it is a DNS issue. On web interface of W8968, go to Network---LAN Settings and change primary DNS to 8.8.8.8, Save it. When you open any webpage, what's the error message?

Faulty unit.

Try to upgrade the firmware 140613. http://uk.tp-link.com/support/download/?model=TD-W8970&version=V1#tbl_j After upgrade, you should be able to select correct region.

How about signal strength when connection drops? Change mode to 11bg for 2.4GHz and 11an for 5GHz to test.
