speed jump up and down

RouterOS Wireless Networking

hi guys
I have this weird problem, I tried to change the cards, cables, antennas but it is still the same.
I’m having the wireless link on about 5KM link with nstreme-dual , here is the configuration:

[admin@MikroTik] interface wireless nstreme-dual> pr
Flags: X - disabled, R - running 
 0  R name="nstreme1" mtu=1500 mac-address=00:09:5B:E7:20:9B arp=enabled 
      disable-running-check=no tx-radio=WLan24 rx-radio=WLan58 
      remote-mac=00:20:ED:0F:F7:00 tx-band=2.4ghz-g tx-frequency=2412 
      rx-band=2.4ghz-g-turbo rx-frequency=2437 
      rates-b=1Mbps,2Mbps,5.5Mbps,11Mbps 
      rates-a/g=6Mbps,9Mbps,12Mbps,18Mbps,24Mbps,36Mbps,48Mbps,54Mbps 
      framer-policy=best-fit framer-limit=3000 
[admin@MikroTik] interface wireless nstreme-dual>

and here is the speed result transfer some files with ftp.




any idea is highly appreciated

Perhaps try killing the turbo on the receive interface? Turbo mode uses a much wider frequency range than standard mode so you are probably generating interference on your transmit interface. I’d try to keep both the transmit and receive cards configured as similar as possible.

Im a newbie to this but is the amount of packets a little bit high??
