Windows 10: 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.

5Ghz band not there

The 2230 is a 2.4Ghz only networking adapter

Multi-Stream, Single Band 802.11b/g/n 2x2 and 2.4 GHz

Delivers up to 300 Mbps speed in the 2.4 GHz band with multiple streams for enhanced speed while improving coverage and reliability.

802.11n supports 2.4 and 5Ghz. Typically for chips that support the 5Ghz band you will see 802.11abgn or 802.11ac listed as there is no marking specifically for 5Ghz N support.

Can't connect to 2.4ghz band, 5ghz keeps disconnecting

Thank you for the suggestion. That repair does seem to have fixed the problem I was having with the 5ghz network (although it's tough to tell if that's completely fixed until something goes wrong), but I still get the "Can't connect to this network" error
when trying to connect to the 2.4ghz band. I'm going to go back through a few of the troubleshooting steps and will update this thread once I do.
