DNS Failing on WiFi

[t3h l337 n3wb]

Hey all,

I've got a peculiar situation. Connected to the WiFi at my girlfriend's place right now but there are intermittent problems with resolving hostnames. She can get on the Internet just fine, but I get a DNS lookup failed. This happens on and off. I can still login to Skype and some other IM clients though.

I've tried Google DNS and OpenDNS, but both yield the same result. I can ping both of these DNS servers, but nslookup times out:

nslookup google.com
DNS request timed out.
timeout was 2 seconds.
Server: UnKnown
Address: 208.67.222.222

DNS request timed out.
timeout was 2 seconds.
DNS request timed out.
timeout was 2 seconds.
DNS request timed out.
timeout was 2 seconds.
DNS request timed out.
timeout was 2 seconds.

nslookup 8.8.8.8
Server: resolver1.opendns.com
Address: 208.67.222.222

DNS request timed out.
timeout was 2 seconds.

These are the other things I've tried so far:

- ipconfig /flushdns
- ipconfig /registerdns
- netsh winsock reset
- startting/stopping the DNS service

I also have a Verizon LTE aircard, which is working just fine. Any ideas?

try to run an nmap -vv against both 8.8.8.8 and 4.2.2.2 and see if they've got port 53 open . . .
you could also simply 'telnet 8.8.8.8 53' i think is the syntax
maybe your provider is blocking DNS requests to servers other than their own? comcast? comcasts is 75.75.75.75 (and .76)
