Just switched from AOL to plusnet for higher speed and not getting it

Remember that there is a relationship between RWIN and MTU, which is:
RWIN = n * (MTU - 40)
where n is a whole number.
n can be 2, 4, 6, 8 or 16

That's explained in the link that was given earlier - by you?
I was just giving examples obviously for comparison. I've seen PC's with relatively low RWIN giving problems.
Also, I've seen several different guidelines on what "n" should be and not just the even numbers given above. The one I followed (can't recall the origin offhand) was that n is around 10*syncspeed in Mb. So a line syncing at 8Mb should use n=80.
(In practice I'm not sure how critical it is to get that multiplier exact though, and your example had n=120 I think)

@HPsauce
My apologies -  I was't getting at you, honest (I read back my post and I could have worded it somewhat better)
It was more for the OP's benefit so that he didn't get the impression that you could use any old number for RWIN.

I didn't take it that way anyway. 
(Always helps to clarify)
