Linksys MR8300 when stable FW?

I've loaded the 19.07.5 . I had to reset a few times because something wasn't working either in the dns or in the routing. Tomorrow I will do other tests and I try to understand better what happens. The problem of the power of the radio module Ch100 persists and perhaps I have discovered why. With the Country in "IT" if I leave the channel management on "Auto" it collapses to 13db.

Below is the verification of the output power with manual CH setting.

Generic 802.11nac
Ch36 23dBm (200mW)
Ch40 goes on 36 with 23dBm
Ch44 23dBm
Ch48 23dBm
Ch52 goes on 48 with 23dBm
Ch56 20dBm (100mW)
Ch60 20dBm (100mW)

Qualcomm Atheros QCA9886 802.11nac
Ch100 26dBm (400mW)
Ch104 26dBm
Ch108 26dBm
Ch112 26dBm
Ch116 26dBm
Ch120 26dBm
Ch124 26dBm
Ch128 26dBm
If set, the 132 goes to 100 with 26dBm
If you set the 136 it goes on 116 or 100 with 26dBm
If I set the 140 I get "Device is not active"
If I set the 149,153,157 and 161 it works but with 13dBm (19mW)
If I set the 165 I get "Device is not active"

Hence the reason why in "auto" it remains at 13dBm, that is, depending on the channel used, the output power is modulated. For example at the moment with the selection of the channels in "Auto" it went on 149 and in fact the power is at 13dBm that is 19mW.

What I would like to understand is whether it is normal that on certain channels of the same radio module I get more power than others. From the performance point of view of the connectivity I would say no for the reason that when the router connects me with the channels with reduced power, under the same conditions and / or distance I will have a performance degradation.


Have you try alternative driver for the radio module qca4019 ?
