I assume that you are talking about a wireless connection for the laptop? Maybe there is a lease timer set for the wireless DHCP? Something that says "grant this laptop a 30-minute lease of connectivity"? Log onto the router (just http://<router IP address> in your browser) and check through the various pages of settings. If you find and change one, remember to SAVE new settings. Hope this helps, --Steve At 8:24 PM -0700 5/31/06, David Minger NPG Cable wrote: >Would anyone have any thoughts on why a home wireless network using Linksys would just log a laptop off about every 30 minutes. After logging back on the same deal repeats about a half hour later.
