Internet access spontaniously halted.

    I don't know WTF happened. I was at work when my router stopped allowing internet access to all computers on my network. (the network is still fine though). I tried going back to linksys firmware and nothing still. Then back to dd-wrt newest firmware -- still nothing. When I set it to static ip I get all 0's.
    My service provider is rogers cable. Could it have anything to do with them?

    Here's something new: when i'm running under osx (usually run xp on my imac) and I plug the modem into one of the lan ports, the internet works again. This didn't work in xp though.

    Does anyone have a clue why this is?

    Not enough info at this point, so the lan works but the wan side does not? Does your router show that it recieved an ip from the isp? What does the routing table look like (specifically looking for a 0.0.0.0 route)? Reason i ask the last one is just yesterday a device of mine lost its default route for some strange reason, nothing a reboot didnt fix but it was strange. If you leave you router set to dhcp on the wan side what does it show is happening. Also could reboot your cable modem then your router then your machine in that order and see what happens?

    The router shows no ip. A little more experimenting with xp and I discovered that with the modem plugged into the fourth port I can use everything but the web browser. I used Bitlord (for downloading torrents) and it worked. Online gaming works. mIRC works. Chat worked.
    I'll try the reboot order and see what happens, though i'm not optimistic.

    Yeah im with you on the last part, if you are getting internet then its not an ip issue, If the rest is working and your browser is not it sounds like dns, however the fact that your wan side IP is not showing anything is tad disheartening because it sounds at that point like something is wrong with your router.

    It has to be the router. I tried it at someone else's place and it didn't work there either. I would just like to know what exactly it thinks it's doing.

    The only way to know for sure is to get a hub and connect it to your isp device to your machine and to the router, and then run a packet sniffer program to see what is taking place between the router and the isp.

    I'm not sure what this means, but when I check the network connections in control panel while connected to the router it shows a gateway labelled "internet connection" and shows that it is disabled. When I enable it it only disables again a few seconds later.

    If you move your cursor over the "internet connection" what adapter does it show that it is bound too?

    Man, I just went out and got a new router. The wrt54gx4. It was 100 bucks off at futureshop. It's up and running perfectly (so far). I'm not sure there was anything I could have done for my WRT54GL. It stopped spontaniously and that is never a good sign. This one worked fine right out of the box, so I can't see it being a problem with windows.
