The WNCE2001 issues addresses out of 192.168.1.0/24 with 192.168.1.251 as both default gateway and DNS server. This is SUPPOSED TO BE ONLY DURING CONFIGURATION OF THE WNCE2001.
However, once in production, the WNCE2001 starts randomly acting as a DHCP server, giving client PCs addresses in 192.168.1.0/24 with 192.168.1.251 as the default gateway and primary DNS.
THERE IS NO DOUBT. The WNCE2001 is issuing these addresses over wi-fi to devices in the office.
Moments ago I received a response to my support ticket, and the CLUELESS SUPPORT REP SAID THE WNCE2001 HAS **NO BUILT-IN DHCP SERVER OF ANY KIND**. That is CLEARLY WRONG because the WNCE2001 NEEDS to issue an IP address as part of the initial configuration process.
The difference is, IT SHOULD **NEVER** ISSUE DHCP ADDRESSES TO CLIENTS ON THE OTHER SIDE OF ITS WI-FI CONNECTION.
