This was my response to RCN email tech support after unplugging modem, using reset button, etc.
Unfortunately this did not solve the problem. I have tried your method many times, including this time. I have been using »pa.speedtest.rcn.net/
to run my tests to stay consistent with you all. In the past two weeks I have not ever gotten anything close to what you are saying your tests show. Currently I use the Linksys EA6500 router. "HOWEVER" I have also run my tests via the link provided, with the cable modem connected directly to my computer via a CAT 5e cable and my NIC card is cable of 1GB speeds.
I have called tech support via phone at least 2-3 times since starting the 50Mbps service, without ever resolving this issue. It's leading me to believe I should go back down the 25Mbps service to get the same speeds I am getting now and pay less. However this isn't what I really want. I really just want the faster 50Mbps speed or at least close to it. I don't think I am being unreasonable. Nor am I one to cause trouble for the sake of causing trouble. I'm hoping we can resolve this. I work from home and I am head of IT for my workplace in VA.
Specs for my computer are as follows, so I do not think the computer is hardly the issue:
ASUS P8P67 LE Motherboard
Intel i7-2600k cpu (water-cooled)
ATI R7970 3GB graphics card
Windows 7 Professional 64bit
