I just set up a little wireless network that starts at a Sprint DSL Modem acting as a bridge to a Linksys 802.11b wireless router. In one room which is only about 15 feet away there is an iMac G5 with an Airport Extreme card. The iMac see's the linksys network and allows the Linksys router to assign an IP address using DHCP - but only if the router is reset. The PC with wireless works fine. If the Mac has been rebooted it connects to the linksys network fine, but assigns itself an invalid IP address. As mentioned the only remedy is to reboot the router... Is there something I can do on either the Mac or the Linksys to get the Mac to grab the right IP address on reboot? I don't want to have to run Cat 5... Thanks in advance.
