Red light on my modem


You should see a lot more than just one red light, I'd think. Sounds like the modem took a surge. I'd look to see if there is a tiny reset hole or button somewhere. If not, leave it unplugged for 15 minutes and try again. May have failed.

My linksys router WRT120N is having power light stable but no other lights are neither blinking nor stable!!! need your help


At power up the device runs a self test, it take a minute or so. What is it connected to, what is sending the signal, a cable modem, DSL, etc.? If you have cables runing from the Cable modem or whatever, to the linksys, try another cable, OR, reboot the cable modem, unplug, remove battery, if applicable, remove power from the WRT120N, Insert battery into the modem, plug in, wait for the self test, plug in the Linksys, wait for self test. Connect a ethernet cable from the linksys to the computer. Does it connect? Try to connect wirelessly, Does it connect? Is the Linksys secured with a passcode? If you push the reset button , and hold for a minute, in the rear of the device, it will reset the Linksys to default settings. Try to connect. Did the Linksys work at one time? Did you set it up? Is it on a surge protector? Have you had any Electrical storms? Surges? It may be bad, hard to say until you verify all the steps. Who is your internet provider? Have you verified that they are sending a signal? Comcast will verify ,by phone, that the signal is good and run check on the cable modem.
