black screen buffering alternating with frozen picture buffering
Maybe someone in your village is watching an old-fashioned TV..?!
Seriously though, the issue you're highlighting doesn't sound like a problem of iFollow or GFC's making. It could be due to factors inside OR outside your home. There are stacks of variables (too many to list) that can play a part in how good/bad your overall speeds are.
Assuming one of your laptops doesn't solely rely on wi-fi networking, my suggestion would be to buy a network cable (RJ-45 patch cable) & plug your laptop directly into your router to see if that helps. That'd be the first step to negating any dodgy in-home wi-fi signal issues.
If you get the same problem, it's likely an out-of-home problem between your house & the local exchange.
Doh! I see LockdownLife has already stated most of the above!
So, some other thoughts on potential in-house resolutions:
It could be that your Windows machine is downloading Windows Updates in the background... Stop that.
Try & minimise/close all your open web browser tabs (eg: close facebook/youtube etc)
Make sure that you don't have pointless programs open in Windows itself - click the little ^ next to the clock (bottom right corner) & close anything that seems unrelated to watching Gills win!
If you have an old laptop with crappy processing power, you might also want to consider disabling your anti-virus software as that can sometimes scan incoming data streams. This is a last resort though & isn't really recommended! Similarly, if you don't have anti-virus software, you should get some!
HTH you stop posting non-GFC guff as promised
