Windows 10: WiFi sometimes doesn't connect with 11 a/b/g/n/ac but connects with 11 b.

I can change my WiFi properties or wireless mode to 1 - 11 b or 12 - 11a/b/g/n/ac.

The default setting under wireless mode in my Laptop was 12 - 11a/b/g/n/ac and it works fine for the most part but sometimes when we have a power cut or when I restart my laptop it just won't connect to the WiFi while other devices work fine. Mind that this only rarely happen but even when I restart my router it's the same thing and then suddenly after sometime it starts working again.

I found a solution which is when I change it to 11 b on my laptop it works fine but it's also very slow.

What could be the problem? Also there was this weird thing that when I connect my iPhone to the WiFi and try again in my laptop then it works fine.

Laptop WLAN adapter b/g/n/ac (1x1) Unable to Connect to 40Mhz Channel Width WiFi Network

Many of clients (smartphones, computers) can connect to this office WiFi network, but not this laptop with Realtek RTL8xxx b/g/n/ac (1x1) adapter. I forget about the radio band of the WiFi router--maybe 2.4Ghz--but it is configured with 40Mhz channel width. I don't understand, why a client with newer wlan adapter that capable to connect in 20Mhz or 40Mhz mode channel width, unable to connect to the wifi router even if the router configured running in 2.4Ghz band and 40Mhz channel width. Please help me. Thanks

Network Adapter Wireless not showing B & N and not supporting 5GHZ

Hi Aneesh,

Thank you for posting your query on Microsoft Community.

To assist you better, I would like to know whether you are using any modem or router.

I would like to inform you that to connect to the 5 GHz band, the card must be rated as A/B/G/N, or AC. I suggest you to check if the router, modem and card are rated A/B/G/N, or AC. Since the card does not show n, this means that
the card does not support the n band.

Hope the information helps. Let us know if you need further assistance. We will be happy to help.

Thank you.
