SOLVED:

  • Home WIFI is set to Channel 4 and has over 90% signal.
  • Neighbour WIFI is set to Channel 4 and has over 90% signal.
  • I set Home WIFI to Channel 1 - it was set to Auto
  • Home Laptop detects Home WIFI 5 times after I switch Router off and on - it used to not detect after 1-2 switches.
  • Home Laptop connects to Home WIFI in less than 2 seconds - it used to take more than 10 seconds.

Problem:

  • Home Laptop doesn't detect Home WIFI except sometimes

Exception:

  • Sometimes Home Laptop detects and connects to Home WIFI successfully + internet works great like when I posted this question. Generally it happens after turning Home Router off and on.

Mission:

  • To make Home Laptop detect Home WIFI

WIFI detection:

  • Everything detects Home WIFI except Home Laptop
  • Home Laptop detects Every WIFI except Home WIFI
  • Home Laptop detects Home WIFI on Neighbour Cable Line
  • Home Laptop doesn't detect Neighbour WIFI on Home Cable Line

Info:

  • OS: Windows 10 Home 64bit
  • Router: Nokia G-140w-G
  • WIFI Adapter: Qualcomm Atheros QCA61x4A Wireless Network Adapter

Tried:

  • Windows Update - up to date: 24.11.2019
  • Windows Reset including deleting files
  • Network Reset + Windows Restart
  • Router Reset
  • Router Unplug everything for more than a minute
  • WIFI Adapter Driver Update - "Windows has determined that the best driver for this device is already installed"
  • WIFI Adapter Drivers Replacement - 3 replaced
  • WIFI Adapter enable/disable
  • Mobile Hot Spot - doesn't detect

  • Is your WiFi network 2.4 GHz or 5 GHz? – Mr Ethernet Nov 24 '19 at 14:01
  • @MrEthernet 2.4Ghz – Ziya Ceferov Nov 24 '19 at 17:59
  • Can you clarify what this means? "*Laptop detects Home WIFI on Neighbour Cable Line. Laptop doesn't detect Neighbour WIFI on Home Cable Line*." So did you temporarily swap your router with your neighbor for testing purposes? This description is somewhat ambiguous and hard to follow. – Mr Ethernet Nov 24 '19 at 18:17
  • @MrEthernet Yes, I swap 2 routers to 2 different cable lines in 10 minutes total. I lost by 0:2 score. – Ziya Ceferov Nov 24 '19 at 22:07
  • @MrEthernet, I added possible reason, check out. – Ziya Ceferov Nov 27 '19 at 16:33
  • If you changed the password for Home WiFi since you originally connected Home Laptop to it, perhaps you just need to choose "Forget" on the laptop and then connect to Home WiFi again using the new password. – Mr Ethernet Nov 27 '19 at 17:49
  • @MrEthernet I am sorry, but I was wrong. A new morning and it doesn't detect again. I plan to try Mobile Hotspot again or buy a USB WIFI Adapter. – Ziya Ceferov Nov 28 '19 at 10:27

The reason why Home Laptop doesn't detect Home WIFI in a stable way is Home WIFI Channel overlaps with Neighbour WIFI Channel.

To solve the problem, set Home WIFI Channel to different value.

Why channel 1, 6 and 11 are best for Wifi communication 802.11n?

Why use wifi channels other than 1, 6 or 11?

Should WiFi routers be set to a channel or choose automatically?

Looking at your list of environment tests (first paragraph), do the following two steps:

  1. Update the Router firmware and then do a hard reset of the router.

  2. Try a different router (borrow one if you can).
