Two cable modems, one router, connectivity problems

Hello,I have two Ambit cable modems in my house. They are literally on topof each other. There is only one cable connection coming into theroom. The cable company installed a splitter right behind my desk andhooked up the two modems (one is residential use, the other acommercial account). The modem belonging to the commercial account isdirectly plugged into a separate business PC. My 'residential' modemis plugged into a Linksys WRT54G wireless router and than to mypersonal PC.With this configuration, my personal PC will intermittently lose theconnection to the cable modem. Only by reseating (unplugging/replugging) either power to modem, power to router or CAT5 cable willit reconnect. I have tried two different routers of the same make,resulting in the same problem. The commercial account never losesconnectivity. When I plug my personal PC directly into the cablemodem, I don't have any problems. At the same time, when the secondmodem is unplugged (power) I can use the residential modem connectedto the router without any connectivity problems.I have also tried switching the two modems to no avail. The modemwithout the router stays connected while the router on the secondmodem fails to communicate.I have called Linksys and they changed some settings withoutimprovement. The cable provider has been out twice but there isnothing wrong with the cable modems. I'm at a loss... Please help!Thank youImLost

I guess we'll have to agree to disagree then.

You can't fight logic. :)
