I have archer c50 ac 1200 wireless router and bought a wa850re range extender for it. However, I am not able to get internet from the range extender even though it is connecting to the 2.4ghz band of the wireless router. I have faced the same issue with netgear range extender as well. I checked the range extender with mobile hotspot and the range extender worked. So, there is some issue with the wifi router. I changed the channel from auto to 6 ,11 from auto and channel width to 40MHZ from auto in the router and tried but did not work. The firmware of the wireless router is up to date.

Please help me resolve this issue.

Thanks
