Hi,

 

Second light would be USB indicator. Doesnt it light up for both cases? To printer or computer? This could happen when an incorrect power adapter has been plugged into the printer adapter or the power adapter has gone faulty.

My printer is a dell 944 all in one. Now all the lights are on but the printer is not responding wirelessly. It only works attached to a usb cable from the computer to the printer directly.

Okay, at this point a little more info is needed as to the configuration of your network. Are you using a wireless router?(brand name and model) Is your computer wireless?(adapter or internal)

 

If you are using a router, is the 3300's MAC address listed in the router's Wireless Access table on the web utility page?

 

Hi there,

 

Thanks for all the help.   Yes I have a router Linksys wireless G 2.4. Also I have 2 computers. Both are wireless. one is internal (the laptop which is a Dell Inspiron 6000 and a desktop which has an adaptor(linksys wireless g  2.4)

 

Yes the mac address is listed in there.

Do all network components(computers, Dell 3300) have an assigned IP address in the router's embedded web utility? Should be a different address for each component...
