new connections stop working after 31 hours of computer uptime.

I have been using a pppoe connection since I installed archlinux in 2006. This works very well. a network cable is connected to my computer and I use it to dial a pppoe connection. I never had any problems with it.

But a while ago, I thought I would share this connection with my phone so I got a router out of the closet. the ISP's cable is connected to the router now. then my computer is connected to the router with a cable and gets a connection through the router's DHCP server. the phone establishes a wireless connection to the phone.
the lease time is 9 hours.
Now after exactly 31 hours, current connections on computer continue to work (existing downloads) but the computer stops doing new connections. so I cannot browse the internet.

/etc/rc.d/network restart doesn't help
restarting the router doesn't help.

only a computer restart does. how can I troubleshoot the problem?

if I connect the cable directly to my network card at this stage, I can dial the pppoe connection and use internet. it's only connections router through 192.168.1.1 that stop working.

PS. I don't have a windows installation so I have no idea where the problem lies.

The next time the issue occurs, try the steps indicated in the Network Debugging wiki page to at least get a basic idea of what is and isn't working exactly (and post relevant output where needed).

http://stackoverflow.com/questions/6799 … tain-sites some guy on archlinux has a similar problem.

here's a wireshark log from two occasions. http://hussam.eu.org/capture.zip http://hussam.eu.org/capture2.zip

some notes:
1. rmmoding the network card driver and modprobing it again doesn't help
2. I hibernated for 10 minutes and I was able to extend it by 10 minutes. I actually did try this once before too. I hibernated for an hour and I was able to extend it to 32 hours (31 awake time + one hour hibernation).
3. http://192.168.1.1 will still open.
4. I have to do traceroute -I or -T. router seems to block traceroute without arguments or traceroute -U.
