Cannot Reliably Connect Devices Home Internet

I was on the phone all morning to tech support, nothing helped really.  They reset my account/line and that made it work well for a half hour or so but it went back to its old ways soon after.

Most things work fine, you can not usually upload any video to facebook from the PC's but you can from an iPad.  You can upload to most video sites from the pcs.  Using wired ethernet compared to wifi makes no difference.  Most streaming boxes/devices cannot get to the internet from these routers.  There is a major issue of compatibilty and web access with these new routers, but even with a 4G connection I am getting about 150mbps downloads and up to 50 mbps uploads.  Its amazingly fast and stable on sites that work well.  It's 4G because I logged into the device menu via the 192.. address and it shows its 4G, but its really fast regardless.  I am in a 5G area so when they synch these to 5G its going to be fantastic.

For now I have to keep Verizon, and I will probably keep this as well in the hopes it gets better.  I will just switch between them as needed.

Playing games on Steam does not work well either, you often cant login or when you can you lose internet while playing, and that makes you lose progress as well.
