I have an ASG box that was working fine for better than a year on AT&T DSL, but when I moved I had to switch to Comcast cable. The same box immediately had trouble with its DHCP client on the WAN port. It would obtain a lease at boot, but then if for any reason the link bounces (happens especially in the rain), ASG is unable to renew the lease without a reboot, and sometimes not even then.
I've tried it both with ARP cache enabled and disabled...sometimes it works one way and sometimes the other, but either way the WAN port seems stuck on the same IP it already had, and the "Renew" button does not refresh the DHCP.
In these situations, invariably if I plug my Windows PC directly into the cable modem it obtains a lease immediately and tests out with a fast, stable connection, so the problem is clearly in the ASG box and not in the modem or the account. I've already tried swapping out the NIC and that has not changed the situation. I also upgraded to 8.0 (now 8.03) and this has not changed the problem at all.
I can't find anything in the logs, but I may not know where to look. I've also found no way to renew the lease manually from the command line; everything I google turns out to be a command that's not available in the ASG bash shell. Any suggestions?
