Hi, a customer of mine (he uses atheros AR5413 on RB 411, routerOS 3.14) is experiencing a large amount of ofdm errors notwithstanding other wireless stats are very good, as you can see below:
signal-strength: -53dBm
tx-signal-strength: -61dBm
noise-floor: -101dBm
signal-to-noise: 48dB
tx-ccq: 96%
rx-ccq: 95%
p-throughput: 30502
overall-tx-ccq: 96%
authenticated-clients: 1
current-ack-timeout: 28
wds-link: no
nstreme: no
framing-mode: none
routeros-version: “3.11”
802.1x-port-enabled: yes
authentication-type: wpa2-psk

group-encryption: tkip

current-tx-powers: 6Mbps:10(10),9Mbps:10(10),12Mbps:10(10),18Mbps:10(10),24Mbps:10(10),36Mbps:10(10),
48Mbps:10(10),54Mbps:10(10)
current-ofdm-errors: 18
Other customers not far from his location, mounting same devices and configuration and authenticated by the same AP, don’t show this errors:
signal-strength: -46dBm
tx-signal-strength: -53dBm
noise-floor: -98dBm
signal-to-noise: 52dB
tx-ccq: 96%
rx-ccq: 95%

48Mbps:10(10),54Mbps:10(10)
current-ofdm-errors: 1
Can someone explain to me what “current-ofdm-errors” means properly/strictly (i knox what ofdm is and how works) and suggest a possible solutions? I haven’t found notes on Mikrotik manual.
Thanks in advance.
