Laptop will not stay connected through USR router

[nds9]

Would someone please help me out here. I have a US Robotics MAXg router that I have had for a year or so, and lately I have had to unplug it every morning because after I turn the computer on, there is no internet. That is one problem. I reset the router, but I do not think that is going to solve that problem.

Problem two is that since I reset it, I need to allow our laptop to connect again. The laptop will connect when I "allow current clients," and it appears to let me add that laptop, but then it disconnects whenever I try to save the settings or add that laptop as a client, where I "add only these wireless clients."

Any solution to either of these issues? Thanks a lot. Tom
