    Is there a way to configure a subnet mask?

    You should be able to configure whatever mask you want, but my curiosity has gotten the best of me. Why do you need such a mask?

    my company uses a local private network that has been set to use a private network address range from "10.x.x.x".

    I know, its overkill, but is has been installed that way before i got employed.
    for eg printers, routers and stuff are on 10.0.4.x , pc and mac are on 10.0.0.x.
    All works well, since its one network.

    Now i bought a wrt54gl and set it to a specific network address, but i cant set the
    subnetmask for the ethernet interface to because the Pulldownmenue only offers "class c" and subnetted "class c".
    I looked for something reliable and got this device recommended.
    (i want to cover some "lounges" for laptop use)

    So, how to set a "class a" (/8) network?

    Far enough and great explanation. I know you can with the lan side but have never had a need to on the wan. Is there a dhcp server on you 10/8 work network? If so just let it accept an ip that way. But regardless i will check when i get home. You may have to update the firmware to something other than factory to get that functionality, that is what i can check when i get home unless someone answers sooner.

    changed to dd-wrt firmware which allows to set class a subnet mask.
    i am happy it worked, since i shot my very first flash job and ever since i am very nervous erverytime i have to flash something.

    Flashs sometimes just go bad, its the nature of how flash memory works. But the percentage is so small its really not a worry. Most of the trouble comes from folks not being patient. Glad to hear all is well.
