So far github is the only website that fails to load.
I can open the website no problem when using a vpn (PIA)
I can ping the github from my computer and my router.
The DNS seems to resolve no problem.
Traceroute starts timing out on the 14th hop. The last ip before it fails is 104.44.20.54 which whois says is microsoft routing peering and dns
My config is pretty much the default one that came with the router.
The router is connected to the isp's ONU on ether 1 via pppoe.
The actual MTU for the connection shows as 1492.
I have tried altering the size of the mtu, 90 is the largest size I can ping github with. Anything larger results in a timeout.
I didn't have any problems on my previous router.
I don't have any networking experience and am totally at a loss on how to troubleshoot this.
Any help would be greatly appreciated
