said by BF69:Even this site has tweak test and I can attest that using such a test and adjusting RWIN when it's off can increase speeds. How is that the ISPs fault? If you have cable internet and the cable running through your house is old or you have it sliced off many times how is less than advertised speeds the ISPs fault? if you have mulitple connections running or an unsecured wi-fi connection the whole neighborhood uses for internet how is that the ISPs fault? I've had people complain about slow internet and a slow computer then it turn out their computer is full of spyware and/or viruses. Or complain about slow internet and I see their computer is 7-8 years old running a PIII CPU and only has 256 MB of RAM and wants to blame the ISP because they can't watch streaming video. yeah ok.
I would suspect 50%-80% of the people getting less than advertised speeds are to blame for their own problem. But hey it's easier to blame the ISP than to learn about how to properly enable your connection.
Just part of the dumbing down of America. They don't read anything longer than a text msg and they expect everyone else to solve all their problems for them.
