Cannot see own wireless network but can see others around me

Hi all,

Seemingly after last Windows update (though I'm not sure) I cannot see my own wireless network on my home laptop. I can see all the networks of my neighbors, but not my own.

I can see it and connect to my wireless network with my Work laptop. My partner can see it and connect to it with her two laptops and her smartphone.

I checked the wireless network adapter (Realtek RTL8723AE Wireless LAN 802.11n PCI-E NIC) and when I click Properties and then Configure, the General tab says "This device is working properly." However, when I look at the icon in the Control Panel under Network Connections there is a big red X next to the Wi-Fi icon and it says "Not Connected".

When I click the Diagnose button the result is "You have not chosen to connect to any of the available networks" (and I can't since I don't know the security keys for those networks). Then skipping to the next step, the next window says "None of the networks you have previously connected to are in range"

Any advice?

    Hi,

    your wi-fi adapter does not support Dual-Band but only the 2.4 GHz band, so you have to manually set the wi-fi channel only on this band. Act on the channel drop-down menu of the 2.4 GHz band and try channels 1, 6 or 11 as described in my other thread. Ignore the 5 GHz band.

    Let me know if you need any further assistance.

    Hi Franco,

    Are you saying I should toggle the 5Ghz to off? Or just leave it and change the channel on 2.4Ghz ?

    Thanks,

    Peter

    Hi,

    no, I did not say to disable the 5 GHz band, you can also keep it, but to change the wi-fi channel of the 2.4 GHz band only.

    Hi Franco,

    I tried changing the channel on the 2.4 Ghz band only. First to 1, then 6, then 11. Each time I changed it I turned off the router for a minute, then turned it back on. I still cannot see my wireless network. Each time I checked the adapter and it continues to show a red X next to it and says it is not connected. I checked my work laptop and it has an Intel (r) Centrino (r) Wireless-N 2230 adapter which is also not dual band, but it can see my wireless connection and can connect to it. Any other ideas?

    Thanks,

    Peter

    Hi PeterY61 ,

    yes, there are other tests you can try:

    -1) Log in to the router via another device, go to the Wi-Fi settings page and try to change the SSID (Wi-Fi Name). Try again.

    -2) Go to Device Manager> network adapters, uninstall the Bluetooth, checking the checkbox: "Delete driver software for this device". Restart and then try again.

    In the Wi-Fi settings>Wi-Fi mode page, expand the drop-down menu, post a screenshot.
