That one is an Ethernet card which is a 2.5 Gigabit. That’s not what you want. I don’t think you need WiFi 6 which is the 802.11 AX standard because you also have to have a wireless router that i can support that. In other words you need a router that has the WiFi 6 AX standard to be able to use the capability. All cards are backwards compatible so they would just use what you have. So if you have a router that is the N standard then it would connect using that. I don’t know what you have but 1.5 Mib is not very fast. That is like 12.6 Mbps (MegaBit)
It may be faster than the connection you currently are using but i don’t know what you have or what you are currently using to connect to it.
Here is a link with some wifi adapters. They only seem to have a few. They do have one Pci-e card but it has to be installed in the computer. A usb just plugs in.
This one is the Pci-e card and is WiFi 6 which you don’t really need. Here is 99.00 Cdn plus taxes.
This one is an AC with USB
Or this one also is AC USB
Edit: These may be too expensive for you? I don’t know what other stores you have available but i can tell you the price they should be in Cdn dollars. Here i can get all different kinds and pretty cheap too. Anywhere from as cheap as $10.00 to over $100.00 Cdn but average is somewhere between depending on what you buy.
Edit: Hope this helps.
