Intersil ISL3887 cannot connect to wireless network with latest Ubuntu

[thewk]

Binary package hint: linux-firmware-nonfree

Sagem XG703A USB WLAN-adapter cannot connect to wireless networks with WEP encryption when using latest Ubuntu. I was able to connect when using another machine and Ubuntu 10.04 image but with 10.04.1 I am unable to connect even if the machine is only couple meters away from wireless router.

Motherboard is MSI K7T Turbo with VIA KT133 or VIA KT133A chipset. The WLAN adapter can see the network and password is asked but it cannot connect. In order to get the card to be detected I had to install linux-firmware-nonfree. Ndiswrapper does not work either, same thing happens.

Howdy, and thank you for helping to improve Ubuntu by opening this ticket. Is there any way to try either with 10.04 on the current machine, or on the old machine with 10.04.1 to help determine if this is truly a regression?

This is likely an issue with the driver for the card. The driver is part of the Linux Ubuntu package.

Hi, sorry that it took so long for me to reply. I now have "new" machine, sold the previous one, I still have the wireless card. I now have Ubuntu 9.10 because I couldn't obtain 10.04 at the moment, the wireless card works out of the box with this version, no need to even install linux-firmware-nonfree. I will try to upgrade to 10.04 and then tell what happened.

Okay, this is strange. I upgraded from 9.10 to 10.04 LTS, the wireless did not function after the update, but when I did install linux-firmware-nonfree the wireless started to work and it connected to the network. The big (?) difference in this situation is that my older computer where it did not work, had USB 1.1 ports and this one has 2.0. The motherboard is ASUS A7V333-X.

But the wireless card did function on that USB 1.1 machine when using Windows XP so the device itself is not incompatible with 1.1 speed, apparently.

I'm having issues with an USB wifi stick with Intersil ISL3887 chipset on Ubuntu 11.10 64-bit with installed firmware for wifi.

I get as far as successfully connecting and auth (using WPA2-PSK) but within seconds I get the following in syslog:

wlan0: deauthenticated from c4:3d:c7:97:79:69 (Reason: 2)

This is followed by disconnection and endless retries.
