MR60 Drops wifi but wired works

Hi

 

I have a MR60 with 2 satellites connected to CAX30 I am using CAX30 as modem, hence there is no ISP modem. ISP is Xfinity

 

On a regular basis ( at least once a day) I notice that my MR60 drops wifi. All devices hard wired to MR60 continue to work. MR60 drops both 5G and 2.4G wifi connections. Generally in about 15 minutes or so it would restore the connection by itself. 

I do not see any errors reported in Log. I do see log lines with [DoS attack: Fraggle Attack] or [DoS attack: RST Scan] on a regular basis. Not sure if this is the cause

I have also seen log line with [WLAN access rejected: incorrect security] from MAC. However the very next line I see a DHCP Ip assigned message for the same MAC.

 

MR60 is running V1.1.7.134_2.0.65. 

5GHz Channel is set to 161 and 2.4GHz Channel is set to auto ( i see it on channel 2).

I had done a full hardware reset couple of months back.

I had seen the issue before I upgraded to the latest version

    Fully converted to bridge mode?

    Netgear's firmware is great at creating those spurious log reports. The issue comes up here regularly. They are generally harmless.

    The logical response to problems like this is not to wait for months but to perform a reset, especially if issues persist after a firmware update.

      I believe CAX 30 only has router or modem mode. Mine is setup as modem mode

        More likely modem/router or modem.

    What is the size of your home? Sq Ft?
    What is the distance between the router and 📡 satellite(s)? 30 feet or more is recommended in between MR and MS🛰️ to begin with depending upon building materials when wirelessly connected.

    Try setting manual channel 1 on 2.4Ghz and 40  channel on 5Ghz.
    Any Wifi Neighbors near by? If so, how many?

      Home is about 2540 sq.ft. The MR and MS are about 30 feet apart. 

      All neighbors around have wifi.  I do not see anyone using the channels I have setup. However I can try switching the channels.

       

      If one channel has congestion, I would expect the other to continue working. Why would both the 2.4Ghz and 5 Ghz go down at the same time?

        Which channel has congestion on it? Try 6 or 11. 1, 6 or 11 are primary channels to use on 2.4Ghz, others are sub channels used by the system. 5Ghz can use any. 

         

        Also lets try using just 1 MS. Not two...That size of home, maybe only one MS is needed...something to try as a quick test.
