I am having difficulty acquiring an IP address when running off my Ubuntu partition and attempting to connect to the Cisco Linksys E4200 wireless router via wireless which is using DHCP reservation for assigning "static" IP addresses based on the adapter's MAC address . DHCP reservation is a feature on the E4200 and E3200 routers that sets certain IP addresses in the pool of DHCP IP address range based on the MAC address of the adapter. The IP address assigned is in essence "fixed" even within the DHCP range.
I am not having problems with this when I boot from the Windows partition.
Also, when I disable DHCP reservation and get an IP address, the conventional way on the Ubuntu partition, I don't have any problems. With DHCP reservation set on the router and when running Ubuntu, I can never get an IP address connecting via wireless. I can however get an IP address when I connect via LAN.
I just wonder if I am the only one who has tried this or anyone else faced the same problem because I believe everything is set up properly. perhaps this is an oversight and has not been tested.
