i have been having an issue pop up the last few weeks at work.
A laptop will try to connect to our wireless network (Cisco WAP4410N accesspoints) but will not recieve an IP address from DHCP(Server2008R2). If i plug an ethernet cable in and do a repair on the wireless connection it suddenly gets and IP(reserved and some not reserved).
I have changed DHCP servers with still no luck. Not sure if its the access points as it happens school wide, and this problem only started showing in the last few weeks.
Wireless points are spread over channels 1,6,11 all running the same SSID etc.
Any help or suggestions would be great.. Please let me know if you need more info
Thanks in Advance
