Nokia Lumia 520 does not see Wi-Fi

Nokia Lumia 520
OS and firmware: Windows Phone 8 Amber

Description of the problem:
Hello.

I bought a Nokia Lumia 520 to see if there was a problem - I can’t see my Wi-Fi access point.

Wi-Fi is distributed using the TP-Link TL-WR841ND router. In the Wi-Fi settings I tried to change the channel number (from auto to 1), but it did not help. He also changed the type of encryption - he still doesn’t find it.

Help with solving the problem please: thank_you:

Router settings:

The problem is still relevant, Lumia 520, the asus router, rebooted both of them, but all to no avail.
The second device is Samsung Omnia, it has never happened before.
Ps. It all started after Windows updates on the phone

I have two TP-Links, 841 and 741, on both the 9th channel. I put it, and no problems.

I confirm. Router ziksel kinetic 2, manually set channel 12 lumiya 520 network did not see. After replacing the channel with 9, the problem was solved.

Gentlemen, I solved the problem by googling the following info:
Empirically, it was possible to find out that the phone does not see access points that work on channels 9 through 13. I changed it to 7 or lower and everything was found right away.
