HELP....Need advance Comp People's help

[Revolution]

I'll break it down quick:

Already talked to ISP and Gateway Tech no good.........Only one person knew what a PROXY was....omfg....

I got 2 sites I cannot connect to most of the time now, but can through a Proxy all the time.

site 1- PSU (I'd post a shocked smile but cannot PROXY blocking)

site 2- www.vivi.com (thats a cool online multiplayer boxing management simulator....Like to know how my boys are doing)

Now what I THINK is possible is the acess number or whatever .......When my dial-up acts ......ELITE.....I can connect to both.....And its all fast.
Now I have tried to delete all cookies and temp files but...It 'feels' like its something to do in the dialup connection whatever its called....

Any input or idea's would help I hate proxies they always make it slower and I am impatient........
