Yes... but RSSI only shows so much. We have links with good RSSI that
have a high error rates. Even the CCQ in MT doesn't tell you
everything, because there is no real "magic" number... is all relative.

Don't you see real time active rissi etc when you look into the ap's
interface listing all the clients?

What I really want is a way to right-click on an entry in the
Registration table and have an option that says "Linktest". It would
test sending 100 packets each direction, 10 times. It would then report:
distance of the link (based on time calculations)
error rate going from AP to CPE (%)
error rate going from CPE to AP (%)
Calculated throughput based on those results
This simple tool has proven invaluable with our Trango system. Our 1st
level techs can login to the AP and do a "linktest" on a customer's
radio and know in 10 seconds if there is an RF problem or something
else. Having to look at CCQ numbers, packet frames vs. hardware frames,
etc. is way too complicated for a 1st level tech.
Yes, we monitor and graph signal levels, bytes, packets, errors, etc. on
every customer we have now... but that simple 10 second test makes life
much, much easier.

With Mikrotik, you have stats for the wireless link as well. You
can double-click an entry under WIRELESS->Registration-Table and you
have a stats tab that will show you tx and rx packets, bytes,
frames, frame bytes, hardware frame bytes and frames. The
difference between packets and frames is loss on the link. I agree
that it would be nice to have a calculated value displayed, but the
information is available. The packet data is available via snmp as
well, though the hardware frame data is not. You can get (from
snmp) the OID that includes errors (in and out) on the wireless link
as well as other interfaces. The OID is found with: "/interface
print oid". Is this what you are wanting?
