Can Wireless Adapters Conflict?

Here's my equipment:

NetGear MR814 Router
1 PC with EDIMAX Wireless USB Ethernet Adapter
1 PC with GigaFast Wireless USB Ethernet Adapter
1 PC with NetGear Wireless Ethernet Adapter

All are 802.11(b). I am using 128-bit WEP.

I have noticed that with only one wireless USB adapter active, the
wireless connection is a stable as a cable.

I start a second wireless connection, eventually one or both
connections will drop and not re-connect. Usually, I have to pull the
power cable on the router for either one of the two wireless adapater
to connect again.

I have never gotten a third wireless connection to connect.

Has anyone else experienced this behavior with wireless networking?

With USB, wireless adapters do not do the connection thing. It's done
by the driver software in the computah. It's possible to have
duplicated the MAC address or IP address of an adapter in the
configuration. If you've setup static IP addresses for the wireless
devices, then it's highly likely. The MAC addresses used are the ones
in the registry, not on the USB device, and can accidentally be
duplicated, usually by cloning a hard drive.

Dive into the various utilities and the MR814 status page and see if
there's any duplication by trying each adapter, one at a time. Run:
ipconfig /all | more
to also check for duplicated MAC's and IP's.

The easiest thing might be to look at your routers connection log and see if
there are any errors being reported when trying to connect clients. This can
be a great troubleshooting tool.

What channels are networks #1, #2, and #3 on? If they're on the same
channel (i.a. all on channel 6), try changing one of them, then change a
second.

Seems like most of the wifi equipment I've installed for people is on
channel 1, 6, or 11.
