I have a 101/15 connection. My problem is that upon booting up into W7 my top Internet download speed is ~ 70Mbps. In order to get 101+ I have to go into Device Manager and change 'any' one of my LAN adapter's settings to something else and then save it. Doesn't matter which setting it is so I suspect a reset of sorts is what's making it work not the actual setting. Also I found an MS program (devcon.exe) that does the 'reset' so I can just run that. Much easier but for some reason having it start up automatically doesn't work, I have to run it manually but that's another issue for another day. My problem might be related to having a large pipe. Perhaps those with more down to earth connections wouldn't even see this if it was indeed a 'bug' in W7. I didn't when I had a 30/5 connection. My NIC is onboard (Intel 1Gb) but I tried two different PCI NICS all with the same result. Router and modem are all gigabit as well as all the NICS. Going through the router is not the issue. My BIOS doesn't have any settings other then to enable/disable the onboard LAN and ROM. Hooking up a laptop running XP to my router produces top speeds without doing any sort of reset. I've changed NIC settings and all the options as shown by netsh int tcp show global. Unless it's my machine for some reason any thoughts on this problem would be appreciated.

i have the same problem. have you found out a way to fix this?

I've found no fix per se. As I mentioned I can either change a LAN adapter setting or use devcon.exe which you can find if you google it. I run my devcon shortcut right after Seven comes up. As I also stated running it automatically doesn't seem to work. Here's how my shortcut looks: C:\Windows\devcon.exe updateni "C:\Windows\inf\nete1g32.inf" "PCI\VEN_8086&DEV_1019" The inf file is the one associated with your NIC, and the other parameter is the hardware ID of your NIC which can be found in the inf file. Perhaps you could give me your machine specs. Maybe we have some hardware in common. Include motherboard, CPU (type, speed), NIC, memory, anything you can.

After perusing the other posts I came across something that I thought might cure my problem. I did a DHCP Reservation in my router for my MAC and IP. In otherwords the router will always assign me the same IP address. After setting this up I've shutdown my machine a few times and every time my Internet download speeds were maxed out. I haven't a clue why this works but I will entertain any thoughts on this.
