I have a laptop with built-in wireless which works fine. However,
whenever this laptop is used, all the other computers disconnect from
the wireless router. I have to power cycle the router before all the
computers can communicate with it again.

If I turn off the built-in wireless in the laptop and use a cardbus
wireless adapter, everything works fine.

Any idea what I should try to get the whole wireless family get along
(without having to use a cardbus adapter on the problematic laptop)?

Thank you very much for your insights and time.

Sorry, forgot to mention that all the computers use Windows XP.

My guess(tm) is that your built in wireless device is duplicating the
MAC address or the IP address of the router.

Have you been playing with spoofing MAC addresses? If yes, remove the
spoofing program and/or its changes to the network configuration.
Similarly, check the IP address configuration for the built in
wireless device, and make sure you have NOT setup a static IP address
that's the same as the router. Set it to DHCP.

If you need further help, please supply the maker and model number of
the laptop and wireless router.

Are all the wireless computers using the same radio format, like 11b, G, or
N, or is the problem machine using something different than the rest? Also
check out the method it's using, Adhock or another method with regards to
the rest of the machines.

IMHO you should inform the vendor of the laptop.
They know how to contact maker of the built-in wireless.

Hi
Which Wireless manger is used in each case? I.e., the vendor's Wireless
software software or Windows Native Wireless Utility (WZC).

In my experience as to 'Wireless' that is quite tricky, unless you know it
well, ...

All of the computers in my household needs to 'G' form of Adapters that are
slower than 'N' form of Adapter. This seems to me primarily due to my ISP.
If I'd use 'N' form of wireless Adapter, I can not connect at all or
simply other PCs can not get Internet.

In my suggestion, try to ask your ISP whether your Laptop built-in wireless
is compatible to ISP that you're subscribing.
Also, I think that Router and Adapter needs to be same form. In my case,
the Router is 'G,' then I can not use 'N' form of Adapters.

Because of my inexperience on Wireless and etc., I wasted quite money
purchasing wrong adapters in the past.

My bias is to assume that, if some equipment needs to be power cycled
in order to start working again, this means that there is a bug in that
equipment.

So ... I would upgrade the code in the unspecified wireless router to
the latest.

If that doesn't work, I would upgrade the code in the unspecified
built-in adapter to the latest.

If that doesn't work, then you could commence troubleshooting.

Hth,

Aaron
