Hi, I have this WR841N router that I use in Wifi Extender Mode, which purpose is to connect to another router (AP) and extends the wifi coverage.

We previously had good experience using it that way until recently the AP router was changed to operate on 2.4GHz Channel 13.

The WR841N thus lost its ability to connect to the AP. A further investigation into the router admin page where Search for nearby Wifi could show all my neighbours Wifi ranging between channel 1 to 11. But not the channel 13.

Before we go with the solution of changing the AP to another channel or using physical Ethernet cable, can it be possible to make WR841N see Channel 13?

Thanks.
