    Hello and thanks in advance for any suggestions...

    I have two computers, Win 7 on one, Win XP on the other, brand new home built machines all updated and latest drivers. Each has a Linksys wireless adapter and each hook up well with a Mac Airport wireless network and connect to the internet well. Neither wireless card has an assigned IP address but get one assigned by the Airport. The computers see each other and can file share over the wireless network without problem.

    I also have a Crossover ethernet cable between the two machines plugged into the jack on the motherboards for a 1 Gb LAN. For the LAN each computer has a static IP assigned with the other computer specified as the gateway IP. File sharing works over the LAN at seemingly very high speeds without problem. The static IP addresses are in a different range that what the Airport assigns.

    The problem is this: when all the adapters are turned on, neither machine will find the internet. The LAN operates fine, the Airport connections seem to be intact, but the browsers cannot access the internet. Turning off the LAN corrects the problem, and even after turning the LAN back on internet access remains for a short time before going away.

    Even though no internet is possible, file transfer works on both the wireless and the LAN; when copying a file over the computers seemingly choose the wireless network first but if one of the wireless adapters is disabled the file transfer can be restarted and will go over the remaining LAN.

    Looking ahead I could probably get rid of one Linksys adapter and use internet sharing over the LAN, but the initial problem is to get everything working and stable.

    Any comments or suggestions appreciated !

    This is an easy one, just configure those direct connections with no Default Gateway or DNS Server addresses, and it'll stop causing you the issue. :)
