wifi ok but not ethernet

[#1]

Did you use the old power supply with the new router by any chance ?

No used the new power cable. I did use my original ethernet cables though, so maybe I should use the cable that came in the box...

That's definitely worth trying.

I just can't see how two routers could be faulty on ALL their LAN ports.

Really sorry - how embarrassing. Using the cable from the box appears to work. I did not imagine that 2 cables would be faulty.

Thank you very much

Neither would I to be honest.

Glad we got to the bottom of the problem though.

At least you've now got  a spare router😀
