Delete any existing wireless profile on your laptop.

If you connect to your phone's hotspot with the build-in Wi-Fi does the connection show it is 2.4GHz?

You can also try to remove the wireless password.

Hello Tony.

I did reset my network profile. And yes, the connection type is 2.4Ghz (Screenshot is from Inbuilt WiFI adapter).

I removed the password, renamed my wifi with no spaces and tried.

Still nothing works.

@Tony 

I am totally struck at this point. I am using Lenovo K8 Note that runs Stock Android (Android 8 Oreo). There are no settings that help me set the channel number to 11. All it lets me do is to choose a username,password and Band (2.4 or 5 Ghz).

Also, I had ordered a replacement on Amazon.in . I'll have to wait till i get the replacement and by the mean time have to figure out how to change the network channel in between 1 and 11.

I found a blog and it appears the adapter does not recognize Network channels 12 and 13.

Please provide a driver update for this issue if possible as it is impossible for stock android devices to change Hotspot Channels.

@Tony 

You are right Tony, the adapter is of the US region.

I contacted Amazon and they told me they do not sell EU version in India. I had to request for refund for the product.

I request you to help me select any other TP-link product on Amazon.in that does the same job at a cheaper price.

I would recommend reaching out to your local TP-Link Support here who are familiar with EU products/pricing: link

Edit : I was dumb I was searching in pc , for everyone else go to ur phone , change the number of allowed device to be able to connect at once to 1
