Ohh it's very reliable. I only had one problem with it, my plant grew in front of it and I just needed to move the plant and it was fine. But if something obstructs the view to the tower it can mess with it. Comcast was always variable, but 5G Verizon I am almost always having 300 + Mbps with the higher package (400 + Mbps) and that's also with a somewhat bad connection to the tower (just in range and sight). Comcast barely got this with a 1Gb package. I'd try it out, Verizon had some good promos, they will even let you test it for a month

I had a similar thing happen. If you can, try to cancel they will ask if you want a promo or something to stay. You can try Verizon 5G, they lock in the price and it works well for me (although it's a pain to try and find a connection, but keep trying took me a few goes to get it in line with the tower). I've been very very happy with my Verizon 5G since
