IP over wireless....sporadic timeouts.

[JeremyUTSI]

Hello all, This might fall under the wireless only catagory, it might not, but it wont hurt to ask. I have a network with approx 12 802.11b AP's, each one hosts wireless connections to 10-15 PC's. Works great except for one thing. Occasionally I have sporadic timeout periods, like 15 minutes usually. RF connection is great, but anything that uses TCPIP (Everything) dies. The weird thing is if I start making changes to my AP's or if I make a change then save the change....then IP will work again. I have this problem in machines that have more then one NIC usually....for instance my laptop has built in 802.11 and ethernet. I still have the problem even if I disable the Ethernet interface in my BIOS. I do not have the problem on a machine that has just a wireless PCI card in it. Anyone have any ideas? Ever heard of anything like this before?

I once looked at an intermittant problem like this, you specifically mention a 15 minute interval. Turned out that the MS clients were performing browser elections every 15 min, and the resultant broadcast traffic sometimes (but only sometimes) caused client connections to fail. May be worth looking at broadcast traffic on your network?
