My internet connection has been really flakey lately, so I thought perhaps I should try upgrading my old wireless router, a Linksys WRT54G v4, to see if that was the problem. Before plopping down the dough for a new 802.11n router, I decided to give the Tomato firmware replacement a shot. It worked like magic! Without spending a dime, I now have a far superior internet connection with bandwidth monitoring and local DNS hostnames that actually work. In bandwidth testing, my connection speed doubled (from 3Mbps to 7Mbps for download speeds on one test server), and the annoying browser latency I had been experiencing seemed to vanish. Anyhow, I highly recommend trying Tomato out if you're not afraid of upgrading your router's firmware: http://www.polarcloud.com/tomato

If you need to test a website in a different version of Internet Explorer from the one you have installed, Microsoft provides VirtualPC images for Internet Explorer 6.0 and later, which can be downloaded here. For older versions of Internet Explorer (3.0, 4.01, 5.01, and 5.5), there's a nifty installer at this site, which will install them all for you. I'd recommend installing that on top of the virtual machine for 6.0 (rather than your regular environment) given the likelihood of unpatched security holes in old versions of Internet Explorer.
