Wireless Router quite working

[BA.]

Normally, you wouldn't want to run two separate wireless systems in the same air-space. They would compete.
It might be that your router's wireless signal has been disabled in some way. Have you ever used a browser to get console to your router?
you may know that the 169.55.x.x IP address is a default range used by Microsoft Windows. That is where it is coming from.

Are you using Windows XP? Is the laptop wireless a PCMCIA or is it built in?

First, we need to determine whether the router is still sending out a wireless signal. At either your laptop or your home machine, can you determine whether or not they see the signal?
On either machine, do you get a wireless/signal strength icon in the lower right hand corner? (system tray)

You can double cllick on "My network places", then click on the left where it says "view network connections"
You should get a window pop up that shows an icon for your wireless and one for your cable modem/router/DSL (whatever you have).
It may also still say "local area connection".

Make sure the wireless icon says it is "enabled".

After that, we would want to check each machine to ensure that the "view wireless networks" window is not showing your wireless router as a "manual connection". You'd probably want it as "Automatic".
