Mystery of two C6300 cable modem router with dual band wifi.

 

  


I have identical c6300 installed at 2 homes (not next door) with exactly the same setup and configuration. Both c6300 have same type and firmware level Dlink cameras connected using wifi. Wifi setting is 2.4Ghz, broadcast, auto channel selection, speed up to 450Mbps, wpa and wpa2 security selected.

One c6300 connects with no problem what so ever. The other devices  triy to connect to 2.4Ghz but will drop. I checked and confirmed as well as change passphrase. Devices that cannot connect include ipad 3&4, kindle hdx, win10 laptop with dual band n. Only device that can connect at both site ont the 2.4Ghz is a LG LGMS323 android phone. Comcast at both site. Let me know if I can provide you with additional details. Thanks

    Don't leave your 2.4hgz channel at auto. PIck a least congested non-overlapping channel (1,6,or 11).

       Thanks for a great suggestion.

      I have been moving to unoccupied channels with empty adjacent channels.

      To bad for me the stated problem persist.

      I may pursuit  an exchange at BestBuy.

       

      Thanks again

        I am eating the lost of 2.4Ghz. wifi ap.

        5ghz wifi is working.

        Guest wifi ap, 2.4Ghz and 5ghz are working.

        I reconfigured guest 2.4Ghz as a replacement for the lost 2.4Ghz wifi. Not sure what the security implication is with using a Guest wifi ap using all the same setting as the 2.4Ghz plus allowing access to other computer on network.

         

        Thanks
