I have been hosting games in the MatchMaker no problem. However, I can't ever seem to join anybody else's game. I get the old "connection failed" message. But even more puzzling is that it "breaks" my ethernet connection. That is, I can't even ping my router any more after trying to launch. I have link, but no IP connectivity.
I have a Linksys WRT54G with all the proper ports opened and the latest firmware. I have a static internet IP address on the router, as well as a static internal IP address on my PC, so there is no DHCP involved. The only way i can get the connection working again is to reset the router. Note, this is not a cable or link problem, as I have tested all these possibilities. My PC has an Intel PRO1000 PCI adapter with the latest drivers.
My only guess is that something is screwing up ARP. Has anyone else experienced this, and if so, can point me in the right direction? Thanks in advance, PG.
