You might try a different channel. I don't know if you're aware that the 3930 is a single band device. As such, all those other devices you mention may be on 5GHz. The 2.4GHz Wi-Fi is pretty crowded. One of my neighbors has one of their Wi-Fi networks set up to take 2/3 of the 2.4Gz band, and that's just one of their 2.4GHz networks. You might also check to see if your router has all modes b/g/n running. It seems that certain Rokus and certain routers don't play well together if the Router is g/n-only.
The Express is really a minimalist device. I used to have one and got 5-11Mbs. When I put the (still quite cheap) Roku Express 4K in it's place, network speeds went up by around a factor of 10.
Thank you. I ordered a Roku Express from Amazon and received it today. Model number 3960R to replace the 3930* model with the slow connection. It can connect to 2.4ghz and 5ghz networks. My connection speed is now 88GBPS. So, I guess I will be purchasing two more to replace the other older models that I have.
I would still like to understand why my Spectrum wifi 2.4GHZ didn't have any issues but the FIOS does.
If you don't mind spending $7 more per device, the Roku Express 4k+ (3941) is still on sale for $25. Comes with better hardware, memory, and a Voice Remote. https://www.roku.com/products/players (can usually find in stores for same sale price when promotions are running).

As for your Fios, you may want to try going into the 2.4ghz band and just enabling 'n' and see if your 3930 devices can connect. If not, try g/n. Eliminating some of the slower protocols like b and g may help speed up the 2.4ghz band. (need to find the sweet spot of connection and speed).
As Strega2 indicated though, the newer Roku devices have improved hardware and should perform better on your network.
