I have 2 x 2,4Ghz Metals in a 9kM link on 25dBi mesh antenna. With default power setting signals into -30's on the other end!
Set radios now to -23dBm to get signals in -50 to - 60dBm range.
Station-bridge on one end, bridge mode on the other. (So a bridged link running over them.)
Both running v6.2 and updated firmware.
While in default power on 20/40Mhz NV2 channel 14 (Japan) units produce a stable 150Mbps conn.rate with an over 100Mb aggregated tcp traffic, units collapse each time after some 20 - 50 seconds.
Its usually the client that needs a reboot to get it back working again.
I have been playin now for over a week to get the link stable but without success...
Tried to swap AP-station, same results but now the other units needs the reboots...
Tried to use nstreme but don't seem to get any reasonable traffic over the link.
Tried with fixed conn. rate and with default; same results.
Tried to lower power step by step. Problem persist with result that powers lower than 21dBm units wont talk to eachother no more while the are still connected with -65dBm and 150dBm conn. rate!
Tried units by day, but also by night and in the rain. Same results so temp. can't be an issue.
When idle the links stays running for days. But everybit more traffic than say 5Mb above, station drops and need a reboot. (just disabling->enabling wireless is not good enough, soft reboot is needed.) Sometimes also the AP wireless crashes... (radio stops because I can't even do a scan anymore to 'see' what can be seen. Scan stays empty.)
After reading all these post here and hearing some other similar stories from a friend of mind I am thinking MT should actually stop selling these units or solve the problem.
The problem itself is imho the radio's. The are not stable and under significant load just collapse.
I think these units have to go RMA....
OH, by the way. The link runs over a town with therefore several hundreds of wifi signals to be picked up. Some with strengths upto -50! Hence I use channel 14. I am the only one there.....
But since the channel 40Mhz wide I am basically covering the whole 2,4Ghz band.
So yes, interference can be the issue. But if the metal is not able to handle this it is not even worth putting it on the market! For empty 2,4Ghz spectrum you have to fly to the moon!
(And probably still picking up signals from us....)
