Comment (by anonymous):
decided to give a try padavan firmware. the interface is impressive.
however 5GHz wireless signal strength seems to be the same as with openwrt
or xiaomi firmware.
while having router right next to me i was able to observe about -40dBm
signal strength in airodump console, at the same time 2.4GHz was going
down to approx. -23dBm
now to quote some of my prevoius post with test result from this ticket
comment https://dev.openwrt.org/ticket/20369?replyto=28#comment:28
>in rare ocasions when connecting to 5GHz network i get 82% of signal
strength at the moment the card connects and only a second later it drops
to 70% or 68%, probably it gives full strength for a short time until the
radio is wrongly recalibrated due to the bug somewhere in mt76 code or
missing PA trigger.
i was able to confirm this: signal strength even if it was stable at
-40dBm would jump to aprrox. -26dBm for a short while almost each time i
reconnected to the network. the reason i stopped seeing this in graphical
interface is most likely wireless backports update from 3.18 to 4
according to these tests 2.4GHz wifi would have slightly stronger signal
than 5GHz (2-3db) and this perfectly coresponds to the situation that was
in the beginning with xiaomi firmware. i can't understand why xiaomi fw
doesn't give this full strength anymore.
another thing noticed in airodump on each router start is some kind of
self connection with these mac addresses
