Laptop not seeing my home WiFi network, but sees all the others

[SFJ16]

Hi,
My Lenovo Y570 stopped "seeing" my WiFi Network suddenly.
It does see all my neighbors' networks (of course can't connect to them as they're password protected). I also turned my cellphone into a WiFi hotspot and the laptop picked it up right away and could connect without issues.
For the modem - everything else in the house connects to it without problem (1 other laptop, 3 smartphones, 1 Samsung TV).
So what can be so specifically related to the individual Laptop-Modem set-up that doesn't work??

Thanks!!

I would go into the network control panel, manage wireless networks, and delete you home network from the list in the problem computer. Then restart, let it find your network, re-enter you security key and check the box to automatically connect.

Thanks but it doesn't help.
When I first got into manage wireless networks there was nothing there, so I added manually my wifi network - restarted, didn't see it; deleted it, restarted, still didn't pick it up. Meanwhile it sees other 14-15 networks around my house.
I simply don't get it what's wrong.

I would try assigning a static (or reserved dynamic) address to the laptop to see if it will connect. You will have to use the MAC address of the laptop adapter and enter it into the router.

Which OS, still the original 7, or 10?

It's still the original 7.
Sorry - but I looked in the Network adapter's properties - can't find its MAC address. Any advice?

Thanks

If you open a command prompt box and type ipconfig /all it will return all of the information about your connections and adapters, including the physical address (MAC address). Just look under the wireless adapter for its physical (MAC) address.

Thanks - I realized that - and entering the MAC address didn't help either.

However - what helped was completely factory reset the router - changed the SSID...and the laptop picked up the network. Not sure why that was - but I'm glad finally I got the WiFi on that laptop back!

Thanks anyways for the advice/help.

Cheers
