We were using UC4800 universal clients connected to P.C.'s and printer via straight thru ethernet cables to attach to the network(AP4800E). Because Cisco no longer manufacures the UC4800E we purchased the Air-WGB350. It appears that we now have to use a crossover cable when attaching these to P.C.'s and printers. Is there a switch, software or hardware, that allows me to use a straight thru ethernet cable?
