I recently bought a mag 322w1 and pretty much nothing plays smoothly on it. My nets usually pretty good even with speeds of 40-50 its just not watchable. And box pretty much freezes at some point every day.
The question I'm wondering is whether it's just a shit box and would the nvidia shield for example be any better.
I have a mag box, I also know quite a few people with mags, it works well 95% of the time. Thats piracy. You could have a 5hit server connection.
I have one and it's not glitchy at all. I use ipguys. Maybe it's your ISP throttling stuff, or the service you have is glitchy. Even on 15 Mbps, it works fine.
I have it wired though as the w1 only has 2.4 GHz WiFi which is not the best for streaming and affected even by a microwave running :)
If you're new to Iptv then you'll quicky realize Iptv is far from plug and play. Takes trial and error and tinkering on your end. Try a new service see if you have issues.
