If more than one connect, network crashes

[chris33]

Hey guys, thanks for taking the time to read this.

We have a Network running on a WRT-110, fairly new router and, at times, 4 laptops all Vista. Any 1 laptop can connect no problem to the network. As soon as any of the other laptops attempt to join the network, the entire network crashes.

Thanks in advance.

Well I'm pretty good but not that good. At least until I graduate Physic school!

More info/details?

What have you done to attempt a fix?

Do you have any wired computers, like a server?

How do you confirm entire network crashed condition?

Are you positive it is not just one computer?

And what do you mean by connect? Just the act of finding available networks, or that works and it happens when trying to connect to a Shared folder, or all works until someone tries to connect to the Internet!

Did you give each Vista Laptop it's own computer name?
Did you setup SSID for the Wireless Router
Did you setup WPA2/AES for encryption
Did you setup passcode (password) for your wireless networking
Did you setup all the laptops to connect to your wireless router.

Take your time and do one at a time. Download this software which is 100% freeware and use it to see how well your network is doing on each laptop. That's right on each wireless laptop.

The lower the -00dBm the better the range

-33dBm is very good -55dBm is good

There is a link test run that and report back how it doing on your network.

Additional thoughts/questions.

What happens if you connect just one Laptop have a connection then disconnect that one and then just try to reconnect the same computer, does it connect back?

If so then disconnect yet again and connect a different Laptop, does it alone crash the network.

Are you using the lights on the router to determine crashed condition? And is powering off the Router the fix back to normal?

Are you using the built in HW Firewall and if so have you tested with it (temporarily) off?

Finally are the Laptops using cloned images from the same image. If so then duplicate SID's may be the problem!

your router needs to be configured to perform the DHCP service;

this will ensure that every computer that connects will get a unique IP address.
allowing a duplicate can cause many and varied symptoms, including crashing systems and/or routers
