Comment 39 for bug 417757

@ Nech / #38

As you have the same DNS server for both wired and wireless, most very likely _your problem_ is not a DNS issue* like what the others show here.

* = unless an upstream of your DNS server has the "drop unknown DNS records" problem and your resolver caches the negative answer correctly, which will cause any subsequent query, like the ones above, to be quick again.

To solve your problem, I guess you'll have to take a peek with Wireshark...
