On a daily basis, at around the same time each day (early morning and early afternoon), my computer stops being able to access google or any sites that use google code (including sites that use google adsense, google api, blogspot, youtube, google itself). This persists until I reboot my computer. I have a laptop on the same network, using the same router, which is able to access these sites just fine, but it's an old laptop and can only access the web in elinks so I want to use the internet from this computer instead.
Based on the output of mtr, I'm experiencing 50% packet loss, 16 hops in the direction of google. My best guess is that rebooting the computer causes it to take a different path to google, bypassing the node that's causing me trouble. Is there anyway to get it to do that without having to reboot?

I had to reboot to ask this question because stackexchange uses google api too, but I'm sure I'll have the problem again later today, as I do every day. I looked at mtr again, and I'm getting no packet loss (as expected after reboot), and it doesn't take a path through 216.239.47.* which is the node that was giving me trouble.
