Network Connection problem 2 of 3 working

Hi.

I recently moved my computer into my new home office.

I transfered my modem, linksys router, and Hiport (t-mobile) adapter.

I have 3 computer on my home network. The main computer works, with internet as well as one of the wireless connections for a laptop. The third laptop is having problems.

When I loose my connection, I unplug and reset my system. First the modem, then the router, and finally the adapter.

I have also done a command prompt, relasing and renewing my ip address.
When IE has connection problem, it comes up with "Cannot communicate with Primary DNS server (192.168.29.1), it repairs and than comes to a security issues concerning "windows firewall/query user."

I can get 2 of the 3 working, but it seems like I have to reset my Modem/router/adapter at least once a day. Please help :4-dontkno

The Adapter is connected to the router, and my phoneline has not been working since the transerfer. Any help with that would be awesome as well.
