Why my 100 mbits broadband slows down?

[Statos]

Hi!

Im very new in this forum, so let we get started. I have windows 7 7068 version, 32 bits. my coumpter is fujitsu siemens scaleo p, with 3 gb ram and double core, not quad core up til 5000+ amd turion. my videocard is an nvidia 8600gs (pretty lame card but it works). I had before windows vista when I get it couple years ago but it sucked, so I turn to xp. It worked, but it had so alot of problems. then I saw windows 7. I try it and I love it! Some error, but not so much.

Now comes a real problem: I have an modem who look like an router, but my isp said it is not a router, is only bridge modem with router fuctions. Then I have an Netgear WGR614v9 what is pretty low tech router. My problem is that everytime I put it on and I tcp tested on it, it slows down from orginal speed 100-92 mbits to 40 mitbs. I thought it was the wireless setting but it wasn't. then I thought it was with the nat firewall, but not. So Im lost with ideas. If u have any idea what this causing this problem and if u had the same problem, let me know then.

I run xp vista and win7. as of late win7 internet using any number of browser is slow. I switch to vista and speed is fine so I conclude win7 has an issue with internet connection.

I too, am having a similar issue. My internet works fine when I am running Ubuntu (on the same computer as Win7) but right when I switch to Win7 my internet slows significantly. Sometimes it doesn't even load pages. I'm not sure what to try, I've tried optimizing my connection but that does nothing. I'm with garyP on this one, it may just be an issue with drivers or Win7 itself as of now.

My speeds have actually improved about 10% since I played around with the TCP parameters

Open up a command box. Type in
'netsh int tcp show global' to see how yours are set.

My setting are:

TCP Global Parameters
