I have purchased a new NETGEAR WGR614v9 wireless router. For security I configured it to use WPA2 Personal using AES-128 for encryption. I have purchased a broadband plan that gives me 2 Mbps connection speed. But I have noticed that when I connect from Windows, I get a maximum download speed of around 55 KBps where as when I use Linux I get a speed of around 150-160 KBps from the same site. (microsoft.com). While updating packages from the Ubuntu repositories, this goes upto 260 KBps.
Are there any known ways of tweaking the Windows stack for getting more performance or is it really broken?
