I am still experiencing this bug in karmic.
Today I tried maverick (running from a USB stick), unfortunately the problem is
still present. First the connection is fine (1.0 MB/s in my case), later the
speed drops to 64 kB/s - 100 kB/s. (I'm testing the speed with 'scp'.) Then I
tried:
# iwconfi
@ sles:
Whenever I notice my rt2500pci's (linksys wmp54g) connection is slow, I
right-click the NetworkManager applet on the Ubuntu desktop, deselect
"Enable Wireless", wait 2 seconds, then enable it again. This usually
works for a couple of hours. Sometimes it's only a few minutes,
sometimes more
I can confirm this on Ubuntu 9.10.
