No power at all, network ethernet lights up but nothing else

Having the same problem. Adapter and MoCA functioned perfectly for one year for Tivo on Xfinity, then one day stopped. Modem/router work fine when I remove the adapter and set them up alone. Bought a replacement adapter, and when it's all plugged in nothing happens except the power light blinks.

orange blinking on ethernet means that your connection is 10 Mbps and green blinking means 100 Mbps
there's nothing wrong with it

Switches arnt not detectable by the computer, a switch allows you to link multiple pcs togethers that sit on the same domain/workgroup , and also network subnet, the other lights will come one when you connect a RJ45 cable between the unit and a PC to show a port is in use.

Do you have any activity lights on the Linksys? If not your switch has no power a hardware problem. Try to power off for 5 seconds and restore power on the Linksys unit. Try to shut down (do not restart) all computers. Are all the activity lights off? If not again power off the Linksys for five seconds and restore power. Power on the computers and verify the activity lights are now green for each computer. If the computers are not networked and the activity lights are green, check your network settings on your computers, which could have incorrect TCP/IP settings or workgroup. If one activity light is not green for that Ethernet connection, check your cable connection or replace the Ethernet cable. The workgroup should all be the same name. The TCP/IP address should be the same with the exception of the last set of host digits which should be unique to each computer address.

Could it be that green is high speed and amber is low speed? Or vice-versa?

hi,
u can try unplug your network card and re-plug it back.

hope this will help.

if the pwr light is on, its not a pwr issue.
if the ethernet light is on you should be recieving a signal.
sometimes you may need to reset your modem and refresh everything in the case of pwr outages or unplugging etc.
i suggest calling your internet service provider and having them walk you through a manual reset of your modem

try holding down the reset button which should be behind or under the router for 30 seconds, still holding down the reset button turn the power off for 30 seconds, still hoding the reset button wait more 30 seconds. After that your router should be in the way it came.

I think you have answered your own problem, your wireless has possibly been zapped.
To test your ethernet adapter on your laptop connect it to a network hub, check the hub and see if you have a link light on the hub and or laptop..
To test your wireless router, connect it to a known working computer with a network card and check the router configuration, using the browser, if you cannot access it then its zapped.

Sound very much like ypur disk is fried. Slim to zero chance of recovery.
