This is a problem that i've narrowed down to the router itself, as i have a virgin router (in modem mode) - and the sites which dont connect work fine on there.

I get the error: ERR_CONNECTION_TIMED_OUT when trying to visit a few websites, one of them being for a piece of software i use daily. They also work fine if i hotspot my 4G from my phone to my laptop.

I reset both the virgin hub and the AX20 back to factory settings, left unplugged overnight. And it worked, once. Then back to the same errors.

I changed the DNS' to 8.8.8.8 and 8.8.4.4 but this made no difference, checked all the settings, parental controls etc.

The only thing I can think of, was the firmware update which was applied the night before these issues started happening, however i rolled back to the 2 previous versions available on the TP link website and tried them both - but nothing changed. I've used this router for 3-4 months now with absolutely no issues at all, any ideas or thoughts are appreciated!
