Windows 10: Wifi Adapter Antenna Questions

Hello All

Switching to Ethernet possibly on Saturday for my Main Desktop, Some reason my Wifi 6 adapter can't hold 1.2gbps with Comcast XB7 Gateway anymore, so wondering something should i disconnect antennas, and just keep the card in for Bluetooth 5.0 function til i maybe replace it with a 2.5gig Ethernet card in the future?


Be first time using Ethernet on this newer PC

Is it safe to plug in the ethernet cord while the Desktop is on, or should i shutdown for 3 month dust clean out, do that, then connect the wire after running it? been about 3 years since i used Ethernet based connection

:)

 

Do USB WiFi adapters supplement or replace existing WiFi antenna?

The USB WiFi adapter will use it's own antenna, the built-in WiFi in the laptop will use the laptop's antenna, and the two will never intermix.

 

Do USB WiFi adapters supplement or replace existing WiFi antenna?

When using a laptop the internal antenna can only receive the WiFi signal that exists in that air space where it is located so it seems to me that plugging in a USB WiFi adapter into the laptop cannot increase the WiFi performance and yet that is the reason they are sold. Is it the case that the USB adapter adds another antenna and the two work together to increase the strength and quality of signal received? Is that how it works?

 

Best homemade WiFi antenna ?

I have been researching homemade wifi antennas for use with my laptop. It has a built in card but I also have a USB wifi adapter I could use for the project.

What antenna have you guys made that works best for you?

Of course I want to boost my reception to the max.
