Need old 1.3.7.4 firmware file

    I just upgraded to 1.3.8.2 and Comcast High-speed internet stopped working through the router (it works fine if I connect my laptop directly to the modem).

    Looks like it is a firmware issue. There is no way I can roll it back, where do I find the old firmware file?

    My comcast modem is RCA DCM425C.

    Many thanks.

    Hello,
    before you roll back, what is your mtu setting. Mostly this incompatibilities have problems with mtu as a source.
    Just poke around and you will see several posts about bad performance or connection loss which are mostly related to mtu.

    I have the same problem with the MTU. I am using two ADSL lines. At default settings, the MTU is 1500 and I cannot suft with most of the websites. After changing the MTU to 1492, the problem is solved. By the way, you can set the MTU under Firewall Tab.
