It has become common to notice the fluctuating pingtimes on APs, mostly but not limited to when client units associate. Ping times on the RB532, for all connected clients, may rise up to 600ms at the moment of association. This is true even for RB client units on a Celeron 1.7GHz MT AP - 40ms latency that is.
Now in a senario with high number of neighbouring CPEs, even those which don’t belong to our network:
-
CPE units are just associating and then being dropped by Deauth. Access List does not help, as if we disable Default Authenticate, then the client unit still connects, tries to associate, and gets rejected(Deauth).
-
By allowing Default Authenticate and clearing the Access List, foreign CPEs still associate, but those with weaker signals keep associating then dropping, thus the same latency occurs.
Does MT have a solution or suggestion to this, as even when there is no traffic at all, ping times still fluctuate. I know interference can also cause latency, but then the latency would last a bit longer. This type of lag lasts for only 2-5 pings out of arround 20. It is becoming like a cycle. Watching the logs, the latency is definitely ocurring during association, deauth or dropping. Funny though, the lag is only between the AP and the Client, and not Tower to Tower Pings.
It is really a major problem as lots of clients are complaining of their stock exchange programs disconnecting regularly. The same goes for gamers…
