DNS Error then "Your not connected to the internet"
Hey,
A while ago I bought a TP-Link RE450 AC1750 WiFi range extender (v3 model) and it worked perfectly. I used it to connect about 8 devices and it had no issues. However, recently I switched broadband provider to Sky (from TalkTalk) and I now only connect my pc to the Range extender (via an Ethernet cable) but not long after this switch I have been experiencing issues as when I try to load a webpage I get a DNS error then shortly after it tells me that im not connected to the internet (this happenes randomly as sometimes it can happen after 30 minutes whereas sometimes it can take 2 hours). My internet is still working perfectly as other people in my household don't experience any issues. It's just the devices connected to the range extender which lose connection.
Factory resetting the Range Extender did not solve my issue and I have a strong 5ghz connection to my Router.
I have looked around on the internet and while I have seen people with issues I have not found a solution.
Here are some screenshots which might help:
Any help would be greatly appreciated
