Internet Disconnecting (Tried all Suggestions from Other Threads: WiFi and Ethernet Affected)

[johnsa14]

I have been having issues with my desktop frequently disconnecting from the internet (~ every 5 -15 minutes for a couple minutes). The desktop is a couple years old and has been treated well (i.e., no click bait websites or likely malware: scans show nothing either). I originally had it on ethernet, but thought this was causing the problem (the problem happens on WiFi or ethernet). After switching to WiFi, I have noticed the same patterns.

It is an HP 750-410 ENVY Desktop (Core i5-6400, 8GB RAM, 1TB Hard Drive, 256GB SSD)

Now that I'm using my new laptop, I realized the internet isn't cutting out, the desktop just loses signal. I have tried the usual suspects: disabled the auto-off power saving feature, factory reset of the router (before realizing it was the PC), turned off bluetooth (which did seem to decrease the frequency and duration of the problem a little), updated drivers, etc...

Anyone have any new suggestions for things to try? I'm not overly familiar with the OS, much less networking, but do know quite a bit with programming in other domains (e.g., Python, R, SAS), so I could probably handle some more complicated suggestions (also, I have tried the obvious power cycling and previously scanned support forums and followed those suggestions with no luck).

I am willing to get a new network card (honestly, no idea if this is what it is or what could be the culprit), but want to know what the likely cause is before investing time and money on that. If that seems like likely case, I'd happily accept suggestions on a new compatible one. My PC is just past warranty, so not likely to have any luck. 

Thank you all in advance!!!
