I have a problem occurring on my wireless at home where after being connected for a while my subnet mask gets corrupted. It goes from 255.255.255.0 to 255.255.0.0. When this happens, my VPN drops and the network no longer functions on my laptop. The only way I have found to correct this is to power cycle my wireless router. Trying to renew or repair the IP from my laptop does not work. This does not happen to my desktop that is tethered to the same router....Any ideas on what to look at to fix this?
I almost always use the my laptop to do work from home via a VPN. The router is a US Robotics 8054 and I use DSL.
Any ideas would be really appreciated, Thanks!
