Okay. I've been dealing with this for a few days. Anytime I am home I am trying to fix it. I would really appreciate any kind of help...going to try to sum this up.
I keep getting "DNS" errors when I try to get online. However! It happens only at a CERTAIN time of day. 6:30PM. I've already Done these things:
flushed my DNS,renewed it. Released my IP, renewed. Tried using Google's DNS servers.
Disconnected router - connected modem directly into PC.
BOUGHT NEW router.
Installed an upgraded motherboard.
Called my ISP (Comcast)
+Installed fresh copy of Windows 7 - same thing
I am going insane here! I know I'm not the only one with this problems. Been searching online anytime I do have access also - people have said they have this problems but there is no "Go to" fix.
I am running Windows 7 64bit. 8Gigs. What I notice: My modem (http://192.168.100.1/) says this

THIS is what it says when I have the DNS error:

Here is the ipconfig /all info which i've seen posted a few times that tends to help in some way.
WORKING (And Not working. Will double check when I get the DNS again to make sure I didn't copy+paste incorrectly):

I thought I would "out cheat" the system. I set my time to 3PM and after a few resets on my router. It works. I am online. Every X minutes it dies and I am getting the DNS error - and I am told I am constantly re-logging on instant messaging services. However during the day the internet works FLAWLESSLY. Only around 6PM do I usually experience problems. I am stumped. I like to do things myself however this time..I just give in. Ready to just move to another house at this point!
