asterisk users - Nov 2006 - wip5000 crash AP

Good day all

I have about 26 Hitachi WIP 5000

They all connect to the 4 Senao Long range AP's 11mb

They all have the same ssi but 2 runs on channel 11 and 2 on channel 1

This way the roaming works well!

We added a UPS and got POE injectors for each AP

BUT..for some reason each now and the the AP's will crash, you can find a
signal when you scan, and you can ping it, the only way to get it back up is
to pull the power in and out

I really don't know what else it can be and has giving up!

Please help

This seems to me as not directly Asterisk related...

I do not know the Senao devices, but I had several network devices
(switches, access points, media converters, routers,...) chicken out
from time to time, and it basically fell back on a single problem -
heat. (Or the device operating system having broken down - D-Link
wireless devices are good at that - firmware updates helped)

Check wether the device operates in a place without air flow - and
change that situation if possible. Something notably above 40?C/100?F
will cause trouble in the long run.

If you want a proper scientific analysis, try hammering the APs with
half a dozen laptops sending files to and fro, and no phones in use at
the same time. I guess it will cause the same problem: Once the CPU in
that device is stressed, it runs at full wattage, and eventually all
those Watts will be dissipated as heat.
