[SOLVED] can't turn rtl8187b wlan card on under ubuntu 9.04 in Advent 9315
can't turn rtl8187b wlan card on under ubuntu 9.04 in Advent 9315
I have a Advent 9315 laptop with an internal RTL8187B LAN Card (I have tested this, though Ubuntu seems to misidentify the card as a Ralink RT25000), where I have just installed a dual-boot system with Ubuntu 9.04 and Windows XP. The card works fine out of the box under Windows. Under Ubuntu too, but here I have an issue that I would like to solve with your help. Given that the FN+F10 hotkey combination to toggle the wifi doesn't work under Ubuntu (the card doesn't appear at all in the list of usb or pci devices), everytime I want to use the card I must restart the computer, go to Windows, press FN+F10 to turn the card on, restart again, and finally go to Ubuntu. The card then works fine, but in an unusual way, because the rt73usb module is loaded, not the rtl8187b one. I can connect to my wlan with proper speed.
I have noticed that under Ubuntu indeed, when the card is on, if I press FN+F10 the card goes off, but further FN+F10 keystrokes doesn't turn it on again.
During the installation my only chance to get Ubuntu work in this laptop was setting the noapic nolacpi acpi=off settings. I have heard that that choice can be causing the FN problems.
My question is: is there any way to activate your internal wlan card under Linux without using the FN hotkeys?
I would appreciate very much your help.
$ lsusb (after activating the card under windows)

workaround found: updating the U50SI1 BIOS
Finally Google gave answer to my prayers: updating the notebook BIOS was the solution.
The most significant feature of the new BIOS is that the wireless is ON by default...:cool:
This update works specifically for model U50SIx (where x=number) notebooks. See the bottom of your notebook to check it out. Follow the instructions. Mine is a U50SI1 and I have done the BIOS flashing with no issues. Now the wireless is always ON at boot. Of course the combination FN+F10 still doesn't work under Ubuntu, but now I can turn the wifi activity off through network-manager or similar.
Should I add the [SOLVED] mark to the post title?
