Yahoo instant mess and wireless connect

By rap1833 ·
I have 2 wireless laptops and 2 desktops using ethernet cableing. I use TimeWarner cable with Roadrunner. Cable modem is connected to Microsoft MN-700 AP and Access Point is connected to 3COM SuperStack II 12 port switch. Laptop 1 has MN-720 card WinME. Laptop 2 has integrated wireless WinXP Pro. Desktop1 is located in a back bedroom and wired through to the 3COM switch. When ever
my Granddaughter gets on Desktop1 and uses Yahoo instant messenger the laptops are knocked off the network. any ethernet connected PC's stay connected fine. Wireless is fine as long as she does not start YIM. I am puzzled. Does it have to do with Bandwidth? Or is it a Switch/ port problem? Thanks

When you say the laptops are knocked off the network, do you mean from the internet, or from the workgroup or both? Or do you lose the wireless connection to the AP? I assume these are all members of the same workgroup for file/printer sharing? Do you get errors/page not found, etc.?
Is the connection restored as soon as YIM is stopped?

Well...never used Roadrunner. Are you using DHCP for IP addressing, or static on the computers?
I can see how you would be getting DHCP from the AP for the laptops, but what about the desktops, since you are using a switch instead of router?

yes the laptops loose internet connectivity Browser says page can't be found, and taskbar message says no longer connected to network.

I am using static IP's on all machines. The cable modem naturally gets it's IP from the ISP. At first I thought my granddaughters pc was set to Internet Connection Sharing and she was cutting off the wireless that way but the Pc' that are "hardwired" do not loose any connectivity. I might throw in a 10 base -T hub and put her on it to limit her bandwidth and see if that removes the problem.
