I am currently running Fedora 14 and have noticed that in comparison to windows 7, I have a slow internet connection. I have BTInfinity and the download speed I get on my windows 7 machine is ~37MB/s. Conversely, the download speed I get on my Fedora 14 machine is ~4-5MB/s. I have tried both speedtest.net and broadbandspeedchecker.co.uk. The results are consistent.
Up until 2 days ago, I had Fedora 16 installed and the speed was still slower on that setup i.e. ~4-5MB/s. I downgraded to Fedora 14 due to some incompatibility issues with some apps while on F16.
I have done a search and have not been able to find a definitive answer for the slower speed on my Fedora setup. Here is the output of my resolv.conf:
# cat /etc/resolv.conf
# Generated by NetworkManager
domain home
search home
nameserver 192.168.1.254

As suggested in another thread, I also tried a ping by name and then IP address but noticed no difference:
# ping -Uc4 bbc.com

This is a wired connection. I tried your suggestions, but still slow speed. I changed nameserver to 8.8.8.8. I restarted NetworkManager after making these changes.

I disabled ipv6 and even disbaled selinux but still slow speeds via speedtest.net. Current download/upload speed on Windows 7 is 33.88Mbs/1.58Mbs. Fedora 14 - 4.36Mbs/1.68Mbs
