You might want to ask your question there. They should have more insight into a Linksys router issue than anyone.
I own one of those routers, mine has been pretty much trouble free, which helps you not one bit.
Are you doing an actual reset, or are you cycling the power? Have you gone into the router menu and checked your access, security, and restriction settings? 192.168.1.1 is the address, your user ID and password are admin/admin if you have not changed them from the factory default.
