Router is invisible just for my PC

Off the wall thought, are you using channel, 12, 13 or 14 on the router and using a WiFi card/driver that can only work up to channel 11 ?

I don't know, I'll check it and I'll tell you what I'll find.

I have found that Channel 3 and 8 have worked out a lot better than the standard channels for the 2.4ghz radio on my Wireless-AC AP. It was a matter of research to find that out for Dual Band A/P's.

Yeah finally I found the problem, its as you said the channel, I changed it to 11 and the problem is solved.
Thank you.

That's great news and thanks for the rep :)

You will find that some devices will not see your Wifi on Channel 11. Especially if they use Wireless-b/g on 2.4ghz. I would use inSSIDer or another tool to find a less congested channel and maybe try Channel 3, which is working very well for me.

the configuration in my router was " auto scan", but why was not I have the problem before ? and why in " auto scan" doesn't work well with my pc ?

Some routers scan for the least congested band to use... perhaps that is what happened and it decided something above Ch11 was the clearest.
