Why are you still with AOL For? They are nothing but problems and a waste of space. I was an AOL user sometime ago and I was sick to death with them, if I had an issue I was speaking to "idiots" in India who you can't understand.
So In the end I rang up for my Mac Code and I had it a few days latter in my mailbox.
I joined Entanet (Falconnet) they where really good but they went "bust" so some other company took over.
So at that time I had my Mac and joined ADSL24 who are an Entanet reseller. And as far as I'm concerned I have had no problems whatsoever. Excellent service the guy who runs ADSL24 is called James hes ace and really really helpful.
With ADSL24 you get No Traffic Shaping or Throttling. UK Based Support who know what they are on about. 8meg Max Speed you get different usage allowances I'm on 30/300gigs a month for £19.99 its excellent value
