    On my laptop 5796 with the new Centrino 2 Wireless card, when i am connected to the internet via internet my dl rates are so slower than when i plug the ethernet cable into my macbook and i am wondering why this is. When i am downloading a file from mega upload my dl speed is like 200kbps, while when i dl the same file with the same ethernet cable plugged into my macbook i get 500kbps.

    Unless your on 11n (at higher speeds >130mbps), the 11g 54mbps (~30mbps -over head) is pretty much std. So this explains your speed difference.

    Unless you have a ftp server where you can test internally it will be harder to test. FTP servers will give you the highest speed due to lower overhead, SMP will give you a min of 20% hit. 1st I have Never seen wireless outperform wired. Wireless over head and packet corruptions always win. Take a GigE network the avg speed on only 30MB/sec unless the end users does some tweeking to get it higher, max should be around 90MB/sec. Then in most cases the speed is capped by the HD and cpu usage. 11n draft which I assume you are on is no different. If you have a pack sniffer like nstat (don't think there is a vista version) to see exactly what is going on during the transfer, it's going to be hard to correct. It could be a simple stack setting, set to low. MFG are constantly upgrading firmware. Newer firmware does not always mean faster speed. It may be only bug fixes that slow it down. Then again the cpu on the router may not beable to handle the encryption and net traffic at full speed. This was a MAJOR problem when 11g was getting near finalization. The old Hardware could run the code but not without slowing down. Now 11n was design to run with WPA2 security, the others slow it down. So before you start saying it's not you will need to provide a lot more info than saying it's slower on wireless than wired.

    Were hear to help you. Provide us with more detail info of your setup will go a long way in locating a solution.
