Suddenly unable to connect to router Linksys Wireless-G Broadband Router 2.4 GB

I am using a Linksys Wireless-G Broadband Router 2.4 GB. I used to connect to it using my laptop which has a Intel(R) Pro Wireless LAN 2100 3B Mini PCI Adapter, I use windows to configure my wireless network settings.

Suddenly I am no longer able to connect to my wireless network. I am able to connect to wireless networks everywhere else. I can see the network, but when I try to connect to it it just times out at one point.

I am not able to identify a specific cause...

could be the dhcp on the wireless, or a corrupted key.
what happens if you log into the wireless and change your encryption or your key

I would recommend hard resetting the router. This is explained in the manual and unusally is a combination of holding the reset button in for a number of seconds and cycling the power. This happened to a clients Linksys router. I hard reset it to defaults. Installed the latest firmware from the linksys website set it all back up and never had a problem since.

Let us know how you get on.

Thanks - Tom

i reset the router, changed the network name, and issued a new key.

now when I try to connect to the newly created network:

"Windows is unable to the selected network. It may no longer be in range. Please refresh the list of available networks, and try to connect again."

But the network shows up with all bars in "Choose a Wireless Network"

This is unusal, how old is the router? What model and version is it?

I have installed stacks of Linksys kit for various customers over the years and only ever had one fail in  100+ installations. I wouldnt think it would be the router however a similar thing happened to a Belkin a year or so ago. It ended up in the bin.

Strange stuff. I am having the identical problem with what I think is the identical router and it happened to me on just about the same date.... I have not been able to figure it out.

Router broken, nothing we can do to fix it. Replaced it completely.
