Slow Internet due to cache?

I have been battling slow internet for a while, here are some basics and what I have done to troubleshoot.
My internet is 100 MBs through Spectrum.
I have an NETGEAR C3000-100NAS N300 WiFi Cable Modem Router that was bought in 2014.
I installed a new HDD but my SSD has my OS and browsers on it. I am not sure if my issues started at this time. This is on a custom built computer that is 6+ years old.
I have 19 phones hooked up through my Wifi. (Long story but they just run apps.)

Before I figured it it might be a cache issue, I would shut the phones down and run the test with no luck.
I can get 110 MBs/second on my browsers but it is just temporary. I speed test through Spectrum.
One browser can show 50 MBs/second while another can show 110. Have done this with four browsers.
I clear my cache and the speeds pop right back up on the test but when I go to a site they plummet back down and stay there.

Any help would be greatly appreciated.

It should not make any difference since speedtest does not cache any data...that would be silly since it testing how long it take to transfer and reading it from a cache would affect the results.

What happens if you download files form say microsoft. Watch the resource monitor for the speeds. Be careful some of them are in B bytes and some are in "b" bits.

I am going to assume you have steam installed, see if that downloads consistently. It does not use the web browser code at all.

So I just ran a speed test through speedtest.net on my Opera browser (Everyday browser that I know is already slow.) and got 50 MBs. I then ran it on Edge and hit 110 MBs.

I failed to mention I just reinstalled Opera yesterday. I am going to assume, but not positive, that my cache, for right now, is being stored on my SSD.

It's NOT THE STORAGE subsystem that's slowing it down. Sweet Jesus! That's not how browsers work when performing a speed test. All that data gets downloaded to RAM first, then any files needing permanent caching will get written to disk after the fact. If for any reason a browser writes data off the network and to disk in real-time for a bloody simple online bandwidth test, then it's a shitty poorly coded browser and the entire development teams needs to be FIRED!

My point in mentioning it is that while some ISPs will temporarily throttle a connect up, some will in fact throttle down as all. So I can't say for sure, but it might not be your computer or LAN, but rather Spectrum.
