like you said it works until You do something.. so its you that should be hit .. LOL...
Back to your problem..
try to setup like a new device.. (Unplug all the network cable..) install the software, plug in ONE pc to the router, then power on the router, then access the configuration page and check your IP address, dhcp etc.
Just another thought:
Did you really press the reset button (its possible that you missed the button, while thinking that you got it)
Unplug it for a few hours and try the reset button again..
Do you get the power to the router? (you might missed watching the light on/off)
Can you return it to the store and ask for replacement..?
I have a Linksys Wireless-G Broadband router (WRT54G ver.4). The router was working fine with a desktop computer, wireless computer and wireless Tivo. That is, until I tried to modify the wireless security settings using the Internet Explorer interface. Before I could finish with all of the changes the router stopped responding.
I have tried many different ways to reset the unit. This includes the Linksys tech suggestion of unplugging the unit, holding the reset button in for 40s, plugging it back in while still holding the reset button for an additional 40s. I have tried countless other "hard reset" techniques. Linksys web support "NetSet" download cannot find the router. The unit cannot be "pinged" from the cmd prompt.
The unit is still not reseting. How do I know? The wireless computer and the Tivo still see it as a security enabled/available network after refreshing the lists. I cannot connect because I didn't yet have the network key. The wired LAN connection comes up "Limited or no connectivity".
The router was working up until I was changing the settings. It just needs to be reset to the out-of-the-box settings. Is there another way to attempt to reset the router? Should I connect the cables differently? Open the case to reset something? Should I hit it a few times with a baseball bat (final option)? Suggestions please!
