WRT54GL NAT problem?

    Well I do not know what exactly is the problem in my WRT54GL (firmware v4.30.9) that sometimes when I turn the router on in the morning, I cannot use net (I generally switch off at night before going to bed).

    My ISP has given me a static IP and router is configured for the same. When router is stuck,

    1) I am able to ping between home pcs (desktop, laptop)
    2) I am able to ping router ( and my static IP (which is given by my ISP)
    3) I am able to ping other people's ip which are in the same subnet (probably my neighbor's).

    4) I am unable to go beyond this point. Cannot ping any websites or ISP gateway.
    5) BUT those websites or ISP gateways are pingable from router's web interface Administrative->Diagnostics->Ping window.

    I tried toggling every options on and off. Rebooted the router. Nothing works until I hard reset (from the web interface) and enter my static IP details. This has happened to me 3 times in 1 month and everytime in the morning when I just switched on the router. (I turn off router during day time too when I go to work but this has never happened in the evening. Scary :eek: )

    Anyways, I have found a quick way to reset my router. These days I backup configuration, reset to factory default and restore config; done in 30 seconds.

    Should I better flash my router to other firmwares? If I do so, which firmware is good and will I be able to revert back to previous firmware by flashing it again?

    You should not have to go through all of that effort, and you should not have to shut your router off. The whole point of having the router is to leave it up, but if thats your thing then so be it.

    If you go to "advanced routing" and look at the routing table, does it should you a default route? Something that looks like xxx.xxx.xxx.xxx (this would be your isp). As far as changing firmware, there are lots of options for your router, tomato, thibor and dd-wrt to name a few i have had experience with but there are several more out there. And yes you can change back to stock firmware at anytime if you choose to do so.
