WiFi router is naughty - not displayed to everyone

Question

Iron

Router DLink DIR-320/NRU. There was a power surge.

After that, it ceased to be visible in Linux (i.e., I see, say, my phone in hot-seat mode, Wi-Fi neighbors, but I don’t see the router on the network)
But on the same computer under Windows 7, Wi-Fi is perfectly visible.
And in niks, if you connect through a cord, then you can go into the router.

An uncle with a laptop on Win 7 has a similar problem - he stopped seeing Wi-Fi.
But such devices as a tablet and an Android phone see wi-fi.

Those. this router is selectively not shown to two OSes, and the rest detect it.

Answer 1

If you do not take into account power surges. Set the channel for example 6 and check what country is. Try connecting to it as Hidden.

Answer 2

You won’t believe it - throw it in the trash (this NRU is not even completed to be disassembled into bolts) and buy a normal router (yes, at least the same 320, but NOT NRU).

Answer 3

Maybe the matter is in the protocols - which one was under Linux and which one does the uncle's laptop support? Suddenly the device switched only to work in 802.11n.

Answer 4

go to the admin panel and try to remove / put "hidden" and it will be saved, after this operation my laptop starts to see it, there was such a "buggy" period and pah-pah passed.

Answer 5

A few days ago it was the same with the DIR-300. Try changing the Wi-Fi channel on your router.
