Network Upgrade For 5GHz Band

Windows 10 Pro / 64Bit

I have a router with 2.4 and 5.0 GHz capabilities. I have a 2007 HP laptop which is pre-5GHz capabilities (I think), can I upgrade it for a 5GHz? Any adapter or up-gradable card for both wired and wireless?
I also have a Dell desktop from 2015. What 'good' network adapter can I replace the existing one with to be up to par with the 5GHz from my router?
Searching Amazon, I found mini USBs, USB with antenna, cards and others. I am not up to par with morden technology with network. What should I do, please?
Thanks.

Yes....if your not on 5ghz get an USB wifi adapter to make the change from 2.4 to 5. I recently picked this up for my sons tower.I picked mine up locally from BestBuy

Yep I know the difference between Wired and WiFi systems. Is a wired female receptor in the laptop or desktop, if 'old', will surely work well but NOT quite compatible with the 5GHz specifications; would it. Case in point would be doing Wired and Wireless speed tests with a fifteen-year old laptop. My two-year old phone got the speed right.

Will head on to BestBuy to see what they have, if not, will order from Amazon (Alaska prices are usually high).
Thanks for the reply. Stay safe.

Is there any point 5g is faster but the range isn't as good so if your distance is a long way away the speed will drop. What is your internet speed 2g n type can reach 300meg so unless you get more you won't gain anything

I had 5GHz disabled in my router. I turned it back on and tested again, in the house.

Laptop Wired Download: 2.4GHz gave me 95mbs.
Laptop WiFi Download: 2.4GHz gave me 19mbs.

iPhone WiFi Download: 5GHz gave me 275mbs.

Surely there is great advantage of the 5GHz since outside the house, I use my phone's data.

Cheers

More network adapter education needed.

What type of adapter did you get. Went to BestBuy and there were a handful of them, though I did not bother to ask since the COVID, associates have bee scarce. Back to the question.
1. In an adapter, any feature(s) I should be looking for?
2. I guess wired would have to now be a USB.
3. Did you get the USB mini adapter or the USB with an antenna?
4. Did you disable the computer's existing settings or remove it from Device Manager?
5. For the desktop, would I need to get a new network card? The PC is 2015, no wireless, just wired.
6. Bye the way, the desktop is connected to a switch, then to the router. Switches don't have anything in it to affect the integrity of a "good" router. Right?

Thanks

For kiks, just clicked the "Robot Check". Thought it is your personal link for business or so.
How has the adapter (make and model) worked for you so far?
