wireless laptop knocking ethernet-bound desktop off network?
I've finally set up my laptop's integrated wireless ethernet thingy so that it's working properly. Now it seems that whenever the laptop boots up and attempts to establish the initial wireless connection, it knocks two desktop machines offline.
Here's my setup:
"Darklord" (the router) is a linksys ethernet/wireless router
"Alex" is my desktop pc, running Windows XP and connected to Darklord via regular cable-bound ethernet (10/100) using dhcp
"Binky" is my wife's desktop pc, running Windows XP and connected to Darklord via regular cable-bound ethernet (10/100) using dhcp
"Mark" is my laptop, running Kubuntu Linux and connected to Darklord via wireless (can't remember the specifications of the wireless... b/g, I think) using dhcp
So here's what happens: when Mark first boots up and tries to establish a network connection, Alex and Binky immediately go offline. When I look at the network connection in XP, it flashes a message that the connection is "broken or severely reduced". Attempts to renew the dhcp connection fail, fail, fail, and fail again.
HOWEVER, Mark boots and gets a network connection just fine.
THEN, if I *unplug* Darklord and plug it back in again, suddenly all three machines work just dandy.
What could be doing this? It definately seems connected to the laptop booting and establishing the wireless connection... I just don't know why or how to make it stop.

Check for a firmware upgrade to router
Sounds to me like something going on at the router, I'd check to see if Linksys/Cisco have a firmware upgrade for the router and see if that doesn't solve the problem.

Re: Check for a firmware upgrade to router
Oh hey, I haven't done that in a while. I'll get to that this evening.

After upgrading the firmware...
The router promptly stopped talking to the DSL modem entirely.
It still maintained the internal network without any difficulties... but boy, oh boy, I screwed something up something fierce...

There is always the ability to reset to PPPOE config.
If you haven't checked that, that'd be my first place to go.

What's the range you have set up for DHCP?
Does wireless run on a different network than cabled? Does it have different dhcp settings? (mine does) If so, what are they?

Re: What's the range you have set up for DHCP?
They're all running on the same network. The router is set to 192.168.1.1 and it goes from there. Is that what you meant?
How do you tell if it has different dhcp settings? I just clicked the "use dhcp" checkbox and left it at that.

Different for different routers, I would expect.
My USR ap gives provides DHCP separately for wireless and cabled, for example. The two networks can be entirely separate. I don't know if your router has this ability or not...
What I was working toward: Is it possible that your wireless machine has gotten the same IP as the router?

Is anything *not* using DHCP?
If your router has a fixed IP, and it's the first IP in the range the DHCP server thinks it owns, then the first system asking for an IP will get the same IP as the router. I did this when connecting the router to the modem, and the modem and the router both wanted to be dhcp servers.
My solution was to allow the modem to provide DHCP in one subnet, which the router requests, and the router provides DHCP in a different subnet, which the computers request on.
