Hi, My name is Eric Moyers. I am a Network Support Engineer in the Cisco Small Business Support Center. When resetting the WAP2000 back to factory these are the steps that I follow.
1) With unit detached from the network but still powered on, hold the reset button in for about 35 to 45 seconds.
2) Attach the WAP directly to a PC and give that PC a static IP of 192.168.1.100 with Gateway of 192.168.1.1
3) Now open internet browser and try going to 192.168.1.245 this should be the default IP of the WAP and the Username and password should be defaulted back to admin - admin
The key is to have the WAP directly connected to you PC so that it does not get a DHCP address by accident. (It normally shouldn't but stranger things have happened)
If this does not reset the WAP2000 back to factory and allow you to get in, please call our Support Center ,open a case and work with one of our engineers. 1-866-606-1866
