I'm on a windows 8.1 laptop, and when I ping 8.8.8.8 the request times out, but 8.8.4.4 works fine. I tried restarting, resetting the network adapter, reconnecting, but it still doesn't work.
tracert 8.8.8.8 gives this result, it keeps slowly getting longer:
Tracing route to google-public-dns-a.google.com [8.8.8.8]
over a maximum of 30 hops:
1 <1 ms <1 ms <1 ms 192.168.1.1
2 * * * Request timed out.
3 * * * Request timed out.
4 * * * Request timed out.
5 * * * Request timed out.
Another windows 7 laptop on the same wifi can ping 8.8.8.8 with no problems.
When I switch my 8.1 laptop to my phone's tethering wifi, it can ping 8.8.8.8 fine, but connecting back to the regular wifi it stops working again.
I looked through the router settings and don't see anything that looks like it would block a single IP for a single user.
