Router disconnects after broadband upgrade

    Hello all. :) I have a new problem with my router and it started after upgrading the broadband to a 30M plan and a new modem. The specs are: WRT54GS v4, Tomato 1.21, PPPoE, VDSL.

    The problem is that the connection will randomly die at any level of bandwidth usage. The only common element is that the connection is actively being used. The green WAN light on the modem remains solid. The router disconnects and maintains the uptime. The only way to restore connectivity is to power off both the modem and router. Otherwise, the modem can never re-establish the connection, manually or automatically.

    An ISP technician has come to check the modem and said there were no problems. I was using Tomato 1.19-ND when it started to happen, tried 1.21-ND and 1.21 to no avail. My theory is that this router cannot handle the WAN throughput of 30M but it seems pretty unlikely that it would kill the connection.

    Suggestions? Would appreciate any input, thanks.

    You might get some more information when you enable Logging to a remote host.

    This can be found under administration -> Logging.

    If you're using Windows KIWI syslogd can help you to collect the logging.

    Regards,

    Thanks rkloost. The next time it happens, I'll dump the log here.

    Grumble: why can't I have a router that's stable for more than a year. :frown:

    If 1.19 was working good for you, why move? Problems you are having VS benefits of upgrade.... you decide which one outweighs the other...

    The problem started with 1.19. :) Otherwise I would have happily stayed with it.

    So it just disconnected twice in a row. Here's a log, probably unhelpful:

    Any hints? But I think at this point, it has to be the modem. The next time it dies, I'll check the broadband TV decoder box, as it's connected to the modem as well...

    Just wanted to followup that it turned out to be the modem after all. But it took three visits by technicians, and the last one was still a little reluctant to replace it and still suspected the router. I guess ISP's don't normally expect the modem to be the problem, even when I kept telling them the WAN light was solid when the connections dropped. In any case, glad this is over!
