I had Quantam Gatway for 2 years and never had any issues. I just added the WIFI WCB6200Q Exteder few days ago. I used WPS to sync the WFI extender with MAIN Router and after adding the WIFI extender, I am having the following issue:
I can not ping certain IP addresses on my home network
I can not see certain IP addreses in WIFI extender's Status page
Radio is turned off on Main router so all WIFI devices are using WIFI Extender to get IP address (DHCP) and to connect.
I CAN TEST Connectivity to all devices from the MAIN router's interface and they all seem to be connected.
I am thinking that the WIFI Extender is having problem finding certain IP devices (routing).
Any suggestions?
