AP1200 12.01T1 sustained heavy loads force need for restart.

On this unit, if any single user (worse if more users do the same) performs sustained "heavy" loads (1.5Mbps or higher) the ping times start climbing higher and higher, eventually staying around 700-2000 ms. If either a warm or cold restart is performed, then it is ok under load for about 1/2 to 1-2 hours, then it starts climbing again.

Any suggestions on how to deal with this? Any setttings that can be changed to handle this? So far only 12 users at a time (max) on this AP.

Thanks.

You may want to try to reset the device to factory defaults and re-configure the AP to see if that fixes the issue.

Tried that a few times on two different AP's and still no improvement.

We moved all of our APs back to 11.23T. What code level did you upgrade from? The 12.01T code can't read the config file properly from 11.21 and caused us problems. Did you back up your configs prior to upgrade?

Re: AP1200 12.01T1 sustained heavy loads force need for restart.

We managed to resolve this by doing a few things.

A: Adjusted the sector antenna downtilt from around 5-10 degrees to only 3 degrees.

B: Changed the preambles from long to short on both the AP's and the clients (compatability to performance)

C: Replaced all Cisco equipment with other better performing, better supported, less expensive products.

We now have over 60 installation sites in a 10 mile by 20 mile valley, and they run great!

The number one problem was using Cisco prodocts for Wisp use, there are far better Wisp concerned products. Cisco is fine for normal office/enterprise use in very short ranges, but almost useless for rural long-range WISP. The other product vendors give far better, decent support at no extra charge (unlike Cisco), have better throughput, better security, better range. We are using a mix of several products (Cabletron, Microtik, 3com, Netgear, Linksys, Lanready, Airbridge (and other series), and others). They all interoperate well with each other, unlike the Cisco products. And have been far more reliable and less headache, and less expensive, and made our customers and our bottom line much happier too.

We are just trying to sell off all our Cisco equipment now, but very few seem to want it for some strange reason. I guess ebay is next.
