My desktop (WinXP Home SP2) is losing internet connection sporadically. I have been trying to figure out if it is the router or the computer that is dropping the IP. This was going on before with my MN-500 router so i figured i would go ahead and get a new router since the MN-500 is 11Mbps wireless speed and i thought that since it was so old it was starting dropping connections.
I installed the WRT54G, no problems for about a week. then the same thing started happening again with my desktop. so i made a little batch file that released my ip and then renewed it. This seemed to work for a while and now it only works part of the time. Nothing on the desktop has changed for quite a while as far as new programs etc. I am very regular with my AV scans (avast) and spyware scans (spybot S&D etc) in addition to defrag and disk cleanup.
i made a quick diagram on gliffy.com to show my setup for those curious about my setup. Again it is my desktop losing connection, everything else seems to keep its connection.
