Can i get better internetz?

[A+]

I recently "cut the cord" and no longer have cable tv. I picked up 2 roku boxes and they work great. I dont know much about internet speeds n'such but im paying ATT for 24mbps. I guess its good enough for my application but is there anything i can do to improve performance, without upgrading to a bigger ATT plan. I have what i assume is standard Uverse equipment for a modem router. Should i switch that out? Ive been thinking about getting a wifi booster since i modem is upstairs, idk. Suggestions?

My only suggestion is if you live in an area with Time Warner for your cable provider, they'll be increasing the speeds sometime this summer to get up to 300mbps.

You have plenty of speed from your ISP. I'd imagine any kind of problems you are having are probably related to the wifi part. Can you run ethernet? Wifi works great for many things but streaming TV isn't one of them.

Do the Roku boxes have any kind of memory buffer settings?
