I have run SAS, MBAM, AVG, and HJT if anybody wants any logs. Everything came up clean, except for the expected tracking cookies SAS found.
This internet problem happens in IE, FireFox, and Safari, and affects my games and pings as well. Speaking of pings, my tracert to anywhere (dell.com in this case) shows step 1 being my router and step 3 being ge-5-2-ur01.saltlakecity.ut.utah.comcast.net, with a "Request timed out" for step two. Does the tracert indicate a problem with comcast?
I think my mom's laptop has the same problem, but I'm not sure because it's a kinda slow computer anyways.
[EDIT] I can confirm that my mom's laptop and the desktop all time out on step 2 of a tracert, and mom says "yeah, I guess" when I asked her if the internet is slow. [/EDIT]
I don't know what do do anymore, I am struggling and need my internet!

Here's the important hardware specs:
Dell Inspiron 1520
Windows XP
Dell 1390 Wireless card (Broadcom based)
Linksys WRT54G v5 and Linksys WRT54G v8.2
v8.2 acting as WAP
Both have DD-WRT micro firmware.
