My wireless USB adapter seems to only work when it wants to

My OS is Ubuntu 5.04, my USB adapter is a MN-510, and I'm using the linux-wlan drivers. After installing the drivers, all I had to do to get my connection to work was:

sudo wlanctl-ng wlan0 lnxreq_ifstate ifstate=enable
sudo wlanctl-ng wlan0 lnxreq_autojoin ssid="" authtype=opensystem
sudo dhclient wlan0

My first time doing that the connection worked and I could use the Internet. When that worked, I restarted the coputer, and on boot up I got the error message:

starting hotplug subsystem:
modprobe: FATAL: module wlan0 not found

Now when I try type in the same commands, the "sudo wlanctl-ng wlan0 lnxreq_autojoin ssid="" authtype=opensystem" will pause for a few seconds, and after it gives the successful message, the adapter doesn't have a connection. Sometimes when I reboot, the same thing will happen, but if I unplug and replug the adapter a few times, "sudo wlanctl-ng wlan0 lnxreq_autojoin ssid="" authtype=opensystem" will return a result instantly and the connection will work. This rarely works, though. Usually when I unplug and replug the adapter, the wireless light will continuously blink and wlanctl-ng won't detect it. If I keep unplugging it to try to get it to work right, both lights will turn off and the adapter is completely useless until I restart the computer.

I followed the directions in the linux-wlan README, but nothing seems to work. Is it a problem with hotplug? What I don't understand is why it sometimes works, but usually doesn't, and why it worked before I restarted the computer, but not after.

Thanks for any help

I have had the exact same problem . Someone on the ubuntu forum suggested putting the prism2_usb driver into "/etc/hotplug/blacklist" to keep it from loading, then running "modprobe prism2_usb doreset=1" and then the linux-wlan-ng commands that you have. I have not got it working on boot yet, but when I do it manually it DOES seem to work, with no more dropped connections.

I would say for JakeMH that he needs to modprobe the driver so it won't get lost when you reboot. Otherwise, you have to reload it. But for mstrimel, you've obviously tried the modprobe command so linux will save your driver. You probably just need to find a way to add it to your startup. Ex. for ndiswrapper, you have to add the line "ndiswrapper" to your /etc/models.preload file to get ndiswrapper to come up on boot and load your module for the wlan0. It's probably something like this that you need.
