Wireless network conflicts-no channel overlap

Hello,

I am having a problem with wireless networking. Two laptops have
802.11g network cards (one is a Broadcom built-in adapter), the other
has a Linksys-G 802.11g network card.
The linksys doesn't have any option to select the channel in the
properties, or at least any option that I see. There is no access point
used. They are set to work in more or less an "ad-hoc" network. And it
works quite well.

The problem that comes into play is when the two laptops are used at a
specific location (a physician's office). There are two other networks
present, one is on channel 1 the other on channel 6. Our network favors
channel 11. The connectivity is sketchy at best when it is used at
this location. We cannot ask the physicans/employees to turn off or
alter their network.

Is there anything we can do to make the wireless connection more
stable? Since the networks are on different SSIDs and channels, they
shouldn't interfere right? But they are.
Is there another channel that tends not to cause interference with
channels 1 and 6?

Thanks in advance for any help.

First, the channel is set by the wireless access point or router. The
channel should not be set in the receiving wireless card; to do so
defeats the ability to connect to a desired network as you are finding.
Use Wireless Zero Configuration, disable any proprietary connection
utility for the wireless cards.

He said:-

I'm wondering if there's another network on channel 11 with broadcast
SSID disabled. A prime example of this pointless attempt at believing
it increases security but in reality just screws people up.

Of course it could be something completely different
