I have a very simple goal with my cpe 510 - to get wifi from my friend's house.

I have my friend's consent for this purpose.

What I did is use my cpe to connect to his home wifi > connect my cpe to my wifi router to broadcast my own wifi.

I set the cpe as a client and it's been working for almost 2 years now.

But now my setup suddenly fails just about 4 days ago.

Now I can't access the internet.

I've tried anything from rebooting to reset my cpe and set it up from scratch using client and ap client but still did not work.

My cpe can connect with his wifi and I can access his gateway router login screen and I can ping it but I can't ping websites like google.com thus I can't connect to internet.

What gives?
