Hi all! Especially Hi to Tom! Thanks for your help. I tried using the --limit-rate switch on wget and it still wasnt using the while speed. Then I found my old USB Stick (Netgear WG111), put some effort in getting the right firmware and all and now I'm happily downloading the Fedora 10 32 Bit

urs - so I believe that this may boil down to the current drivers in the Fedora kernel? The ipw2200 one is actually the slowest - and 4965 whizzes along very nicely and a lot faster - and all are basically the same setup! Would be nice if others may be able to confirm this? -- View this message

ing WPA and rsync - so with a native speed of 54mbps that translates to just under 7MB/s and therefore I am expecting about 3.5MB/s which is not too far away from what I am getting from that machine - all the others are slower. -- View this message in context: http://www.nabble.com/Poor-WiFi-Perfo

ces other than driver differences... but maybe you know more about this than I do? I use rsync regularly to run backups and to copy update rpms so I see these numbers coming up with a lot of consistency. -- View this message in context: http://www.nabble.com/Poor-WiFi-Performance-tp21655322p2177
