    I have a client with Tomato 1.26 (standard) running on a WRT54GL.
    I have not heard a peep from them in almost a year.....

    The site contact emailed me yesterday stating that everything was running fine until the cable company converted/upgraded their TV signal to all digital.
    After this, the site noticed that their Internet slowed down considerably.

    I am trying to determine if they (cable company) replaced their modem with a modem/router combo and they are double natting. I looked at the logs and I am seeing a 10.X.X.X address being blocked constantly
    (There network is a 192.X.X.X)

    This leads me to believe Charter/Suddenlink may have changed out their "dumb modem" to a router/modem combo, thus causing the slow down becasue of the
    existing wrt54gl and Tomato. I am awaiting his reply as to if they swapped out the original modem.

    Has anyone experienced anything like this (after a Digital Cable upgrade?)

    So it sounds like they had their own modem before? If they replaced it with a new modem supplied by charter, i'd suggest going back to where they were....i.e. buy your own modem and use the GL. I'm surprised they just swapped the old modem unless it was one of those older linksys 1.0 modems.

    Comcast in my area went through a big upgrade this summer and it didn't affect my internet in a bad way. We got DOCSIS 3.0 so I bought the SB6120 modem since comcast raised their modem price to $8 a month. We also received the TV devices to convert digital to analog for the old TV's in the house.
