How to use only USB Wi-Fi card and make a hotspot from the built-in Wi-Fi?

br flag

I am trying to use my laptop as a hotspot. I do not have a LAN cable however, but only a USB Wi-Fi card (Netgear A6150).

I am trying to Turn-off the built-in Wi-Fi, get internet from the USB card only, and then share the connection via Hotspot from the built-in card.

I followed the discussion in How to disable built-in Wi-Fi and use only USB Wi-Fi card?. I can disable my built-in card via editing /etc/network/interfaces and then doing sudo service network-manager restart. But then, problem is, my built-in Wi-Fi becomes completely unusable. Or at least I do not know if/how to do anything with it.

So, again question is, how can I use my built-in Wi-Fi card as a hotspot, while getting connection from the USB. As a small note, previously I was using LAN cable and I was able to turn on hotspot from my laptop, so turning it on, should be possible.

If you want to share from the internal card, why would you turn it off? This seems illogical …

If both are enabled, I cannot turn on the wifi-hotspot, so I tried by turning the connection off.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
