my wi fi orange light is blinking on my lexmark x4650 printer


The blinking WiFi light on your printer indicates either your printer is trying to communicate with your wireless network or your printer is not connected at all. For a quick fix, try to disconnect your printer from the power outlet. Power cycle your router and reboot your computer. Then, power on your router first, then your printer and lastly your computer. Check the WiFi light on your printer. If it goes to a solid green, that means you are connected back in your network. If not, you may reset your printer's wireless network adapter to its default settings. From the printer operator panel, press the Setup button > Network Setup > Reset Network Adapter to Default. The WiFi light on your printer will momentarily turn off then back on solid orange. Then try to run the Lexmark Wireless Setup Utility on your computer to reconfigure your printer to connect to your wireless network.
I hope this helps.

What does it mean when there is a solid red Power light on the ATT 2wire DSL wireless router?


it means 2 things. 1st it could be the adapter because theres still power to it and 2nd is the 2wire router is already defective. if its possible for you to bring the 2wire with the adapter to any computer store or to att store and have them plug a new adapter on it . or if you have available 5volts adapter you can try to check if power will be solid green using diff adapter definitely its the adapter but if you have tried it but power will flash green or red the modem is dead. powerlight of any router should stay solid green no matter what happen.
have it checked carefully so you dont need to spend $82 for the 2wire, adapter is $10 only..

Goodluck!
