i have a problem with a Mikrotik Bridge 2,4 GHz using R52 and 19dBi Antenna on booth sides.
I tried to turn the max power on 25dB (with winbox), i also turn power on, without a antenna on the MikroTik,
just the pigtail cable.
After 2 hr i turned the power of the card to default values… it works fine
2 weeks later, we tried the Turbo G mode (-82dBm, Troughput 12 M)
and after 5 hr working the MikroTik lost the connection.
After this we changed back to 2,4 B/G mode, but now the troughput is 30 -200 k and -90dBm
I am no think that card is broken RX/TX signal level is very close.What is 2,4GHz link distance? You need get -60 -70 signal level for good connection. Check Line-of-sight and equipiment ( pigtails, cables, antenna polarization ).
