I have always enabled the default storm threshold on all our units. Early testing indicated better performance when overlapping coverage from multiple access units.

One thing I have just done is enabled the storm threshold (using their default value) and this seems to have solved the problem, mind you I'm still waiting for all the test results. But when the transfer rate was fluctuating down to 1mbs, we saw non-unicast packets also shooting up, and a constant ping that we had running started dropping packets. Enabling the storm threshold in the AP-2 seemed to prevent this from happening. Has anyone else had success using this storm threshold? Or should I have had that turned on from the beginning (quite likely).

I took a laptop up with a wireless client and did some testing. It seems that the transfer rate between laptop and Access Point is pretty much always fluctuating from 1 to 2, to 5 to 11 Mbits/sec. I don't seem to have a lot of noise based on what the client software tells me. Has anyone seen this? My guesses are at the following: > > > > - A flaky card in the Access Point itself. > > - The positioning of the Access Point. The access point is mounted on the side of the wall, with the lights facing downward towards the floor and therefore the cards facing upwards. I'm wondering if this may case some of the problem. > > - We do have 2 cards in the Access Points. The channels are separated as best as possible, but it's possible some leakage from upper floors may be causing interference. Should I play with the "Distance Between AP's" setting if I have two cards in the one AP? > > > > Any advice/comments you could offer would be much appreciated. > > > > Cheers > > > > Matt Ashfield > > [EMAIL PROTECTED] > > > > ********** > Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/memdir/cg/. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/memdir/cg/. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/memdir/cg/.
