Re: 2 Laptops, only 1 can be on WAP at a time

First of all the 2 Cable Modems thing. There are approx 12 computers
in our Living Room, and we all like to game and download, so if we all
shared one modem, it would get clogged up, and that would reduce our
online performance. That is why we have 2 Modems.

I see what you are saying about the routers. There are actually 3
routers so to speak.
There is the Cisco Router (7200 Series I think) that has an internal IP
of 192.168.1.128, and an external connection to Cable Modem 1.

There is the Solaris Box (I called it Linux earlier, but I forgot the
Linux box died) that has an internal IP or 192.168.1.1 and an external
connection to Cable Modem 2.

Determining which Cable modem a PC uses is determined by what IP they
use as their gateway. Otherwise all systems within the internal
network have 192.168.1.x IP addresses, assigned either statically or
through DHCP. The DHCP server has a 50 IP pool at the top of the range
that is not in use by any of the statically assigned PCs.

Both of the above router devices are connected into a Cisco Managed
Switch. VLANs are not actually being used on the device at this time,
though the ability is there, so that could have something to do with
the problem.

>>From the Cisco Switch, all other PCs are plugged directly into it with
IPs in the 192.168.1.x range. In addition to all PCs, there are the 2
Wireless devices:

The Linksys WRT54G (essid = BobbieBrown) that is running on channel 1
with WPA PSA TKIP enabled in mixed b/g mode.

The DLink DI-514 (essid=MikeTyson) that is running on channel 6 with
WPA PSA TKIP enabled in mixed b/g mode. This device is a router
(unfortunately), The WAN interface of the device is set to a
192.168.1.x IP address, and the LAN interface of the device is set to
192.168.2.1 and is a DHCP server giving out 192.168.2.x IP address.

Just to reiterate, the chief problem is the Laptops disconnecting from
the WAPs. All 3 Laptops are running Windows XP (2 Home, 1 Pro) and all
3 have the Intel 2915 ABG wireless card. Disconnects occur whenever a
second Laptop connects to an already in use WAP device. It occurs with
both the DLink and the Linksys. I think the issue is somewhere in the
settings on the laptops. Though it could be somewhere else.

I would tend to rule out the Cisco Switch as the DLink Router should be
reporting 1 IP address back to the Switch regardless of how many
devices are connected to it. Also, the disconnect is actually from the
WAP, and not from the switch. When one device associates with the WAP,
the other device physically disconnects from the WAP. So the problem
seems to be somewhere between the WAPs and the Laptops, and not in the
rest of our Network design/setup.

The reason I am using two WAPs is completely because of this problem.
If I could get 2 or 3 of the Laptops connected to a WAP simultaneously
I would remove the DLink device from the network completely. This
problem was occurring when it was just the Linksys, and the DLink was
just a fix (sort of) for that.

Thanks in advance.
