  • Scientific Atlanta Cable Modem/Gateway problems

    Hello, i'm not sure if this is the right forum but i thought i'd give it a chance..

    Before starting, i'm gonna say that i tried to contact my ISP, but they said my connections are OK from their side. So no help from them.

    I'm using EPR2325R3 model of this Modem.

    The problem is that when i've been online, let's say, more than 2h, then suddenly i can't browse anymore as all the websites get "Timeout" error. Yes, i tried it with different browsers - same. Though other protocols (like P2P, Skype, MSN, etc) work just fine.

    It happens with all the 3 computers. One WinXP machine is connected to the Modem via cable, other 2 Vista laptops are via WiFi. In my modem settings i've put my WiFi under password protection with WPA-PSK TKIP encryption (It's the best it offers).

    The only way i can resolve this problem is by disconnecting and/or restarting Modem. Then it's just fine the next 2-3h when suddenly, again, it gives me Time-out errors constantly. For all the sites.
    At first i though it was some kinda port problem, like port 80 (HTTP), but HTTPS (443) sites do not work as well. Other protocols work though - why's that?

    My modem show Receive/Send lights working just as should, Cable light works flawlessly (so i take that the Cable coming from wall is ok?), Wireless is OK.

    What can be the cause? Why does Modem suddenly get "flooded" with something. If it's the case, of course.

    I checked Firewall - Event Logging and it reports following:

    What does it mean exactly?

    Also, is there maybe some new Firmware update for this modem? I have 11/06 build.



    Thank you very much for helping me,
