After several weeks of blissful problem-free connection (thanks again, Doobeius), my connection seems to be playing up again. At least, I'm assuming it's an issue with my connection. For the record, still connected to AOL and still using a NetGear DG834Gv3 router.
Completely at random this morning, Firefox and Internet Explorer, on all three computers connected to the network, began to timeout while loading certain seemingly random webpages, such as YouTube and - interestingly - some ProBoards forums, but not others (say, I can open forums on .proboards104 or .proboards21, but cannot connect to any forum on .proboards74). Pinging any of the problematic websites in a DOS window result in similar timeouts, while pinging websites like Google return perfectly. The problematic websites will sometimes load in the AOL 9.0 browser, but will sometimes timeout there as well and consequently cause the browser to crash.
I did try changing my MTU settings, which seemed to work last time I had issues accessing certain websites, but that's reaped no result thus far (and I've currently left it at 1400).
As last time, any help would be greatly appreciated.
