My roommate and I bought a Network Everywhere NR041 4-port Cable/DSL router (the Linksys economy line, I know, shame on me). It's been working fine for what we need it for, but there is one glaring problem that the router has. We have cable and we don't have a static IP address. I figure the DHCP lease expires once a week, maybe a little longer than that. When our modem receives a new IP address, the router crashes. This has happened twice so far. The router doesn't respond and I have to power cycle it. The firmware version on the router is 1.2.06 (newer, in fact, than the firmware that Linksys posts on their website, which is known to have a security flaw in it). The modem is a Webstar DPX2100.
Any thoughts? Thanks in advance.
