I have a belkin N wireless router f5d8236-4 v3. it has worked fine for almost a year. 2 weeks ago, the wireless icon started flashing amber but i was still able to connect. now i cannot connect at all. i've tried rebooting and resetting it. everything else is blue. i just hit the tool icon button to reset it and everything came back on except the wireless icon which isn't even blinking now. i haven't changed anything to cause it to stop working.

FixYa's Maanita was no help whatsoever, and worse, a complete waste of time.  I called Belkin who's tech guided me to the problem in ten minutes, whereas I wasted an hour and a half with FixYa. 

SOURCE: no internet connection

I received this solution from Belkin. It worked for me & I hope it does for you. Good luck!

Belkin solution:

The connectivity issue with your Belkin router could be due to a couple of different items. Your ISP might even be able to shed a little light on the subject.

I would also go to Belkin's website, and go to the support area by clicking on Support Center in the left pane of the sight. You can then search for your product number. With the results that you receive, you will be able to see what version of firmware they have, which is like doing a software upgrade on your computer. There should also be a step by step process on the website for you to install the firmware. I would do it from a desktop that is connected physically to the router.

Please let me know if you would like further assistance with this matter. Thank you.

that means there is usually a problem with your modem. you know how to hook up a router, right? usually you unplug power from both devices, plug in your modem and let it load, then plug in your router. (with some isp's id will work the other way around.
