Jaunty, rtl8187b: wifi doesn't work

[Oliver Gerlich]

Binary package hint: network-manager

When testing a Jaunty beta install (from USB thumb drive) on a Toshiba Satellite L40-14N laptop, wifi didn't work. The AP is found, and after selecting it, one of the two green dots appeared in nm-applet, and I was asked for password (network has WPA and WPA2 I think), but got no connection then. I'm sure the password was entered correctly.

The laptop has a Realtek RTL-8187b chip (vendor ID: 0x0bda, product ID: 0x8197) which works with ndiswrapper under Hardy and with some native driver out-of-the-box under Intrepid Live CD.

This is with linux-image-2.6.28-11-generic 2.6.28-11.36 and network-manager 0.7.1~rc3.1.git4cf2da146-0ubuntu1 .

Please tell me what further information you need; but it might take a while until I can get it.

please reproduce and attach you complete /var/log/syslog.

Here's the syslog from yesterday's failed connection attempts. AP name is "wlan_privat_wbs". Boot on the affected machine starts at Mar 22 16:35:07 timestamp.

please try the linux-backport-modules-jaunty package after installing that you need to reboot to use the new drivers.

After installing linux-backports-modules-jaunty 2.6.28.11.14 (and installing other upgrades), wifi works fine now - thanks a lot!

my wifi 8187b works, but only near AP router (DIR-320) and , some times, with iwconfig wlan0 rate 1M

with linux-backports-modules-jaunty the wifi works better, and migrate better between APs on enterprise (DIR-320 and NetGear) without reconnecting or disconnecting.

Actually, it doesn't seem to be fixed. The range is increaded to about 30-40 feet on my machine. Is there still work being done to improve this driver?
