Have you tried running a repair command on the LAN connection? If not, an easier way to get pretty much the same net result is to open up a command prompt (Start-->Run-->cmd) and type in ipconfig /release and hit enter. Then follow it up with an ipconfig /renew. This will renew your DHCP lease, and very likely "kick start" your connection again without having to reboot.
I have a high speed internet connection with an external modem that is connected to my computer. Recently I have noticed that once the computer is left idle for a long time period I am unable to access any websites. Every time this happens I have to restart my computer to reach any website.
The weird thing is, yahoo/MSN messenger remain logged in as well as a downloading torrent that continued to receive data. It's like the connection has some kind of activity timer where it shuts off if it is inactive for a long period.
