DHCP doesn't provide DNS servers
« on: March 13, 2010, 01:54:01 PM »

I've set the DNS servers in the router to OpenDNS. When I connect to the router soon after it connects to the Internet (currently a problem since it seems to like to flap up and down) it doesn't provide the DNS servers. Originally, before I switched to OpenDNS, I thought maybe this was because it wasn't getting the servers from my ISP's DHCP server. However since the DNS servers are static on the router it should have them even before it gets any response from the ISP.
Here's what it's supposed to look like:
Code: [Select]

Mar 13 13:40:06 zelbinion dhclient: Sending on   LPF/wlan0/--:--:--:--:--:--

Here's what it does quite often:

What's going on here? Why isn't it providing the DNS servers?

Been four days, giving this a bump. Will wait longer for my other thread as this is, by far, the most annoying problem (after the securespot crud).
