I heard about netlimiter but I'm a bit wary of that getting detected as a cheat or whatever in online games (people abuse it because lagging out on command can be advantageous).
I'm wondering if the router might have something to do with it. I never used to have this issue before but I only use iPlayer extensively enough to notice every now and then, and we changed router a while back when Sky bought out Be. Hoping to avoid having to buy something though, since it's just an occasional problem and the Sky router otherwise serves well enough.
Using 24/1.5mb ADSL from Be*.
