I'm running Fedora 15 on a laptop with a Broadcom 4318 wireless card. The Network Settings shows I'm connected at 54 Mbps, but my actual download speeds tested with speedtest.net show only about 0.15 Mbps download and 0.24 Mbps upload. My service is 2 Mbps download and 0.5 Mbps upload. I'm using the B43 driver. Any ideas on how to correct this?
The first thing to do is to figure out exactly what that needs correcting.speedtest.net does not measure the speed between your laptop and your router, they measure the speed between you, and their servers. The same goes for any other web-based bandwidth measuring service. None of them have a magical ability to hack into your wireless router, and open a direct connection from your wireless router and your laptop, in other to measure how fast you can fling packets to your router, obviously. All they can do is measure how fast you can download something from them.
Unless you are sitting in speedtest.net's data center, and your wireless connection goes directly to their network, your speed will also be obviously impacted by your Internet provider's performance, and every Internet provider between your provider, and theirs.
So, in order to confirm that you have a wireless performance problem, you will need to perform exactly the same test, but this time with a wired connection to your router. If your bandwidth is now close to your expected 2mbps bandwidth, then only that would demonstrate an issue with your wireless setup. If you still end up getting subpar bandwidth, your wireless bandwith would obviously not be your issue.
