There's honestly some other stuff wrong aswell but I'm just gonna focus on this issue in this post.

My pc usually gets 500mps speed over Ethernet to my telus network acess hub, it's connected via a 100 foot cat 7 cable.

Now suddenly my speeds seem to be hardware capped at 100 up and 100 down

My pc can connect to the router but can't access the Internet, It just says secured no internet.

All my other devices can connect to the routers wifi and work perfectly with over 300mbps down speed

A damaged cable would explain my capped lan speed but it doesn't explain why my pc can't acess the Internet through my routers wifi.

Does anyone have any theories?
