Ubuntu 11.04 wireless connection 802.11 Draft-N not available
I have an Acer Aspire 2930Z notebook, and have a wireless network problem...
When I installed Ubuntu 11.04 everything worked out of the box and I was extremely happy, but now that I have some other notebooks around I noticed that transferring files to the Acer Aspire 2930Z notebook did take a bit longer...
So after some digging I found out that the 2930Z only connects in the IEEE 802.11b/g range (max. 54mbit), while the specifications of Acer clearly specify that it also supports IEEE 802.11-Draft-N.
When I run MS Windows XP on the notebook I have no problem connecting at the Draft-N speed...
The notebook, a Acer Aspire 2930Z, has 802.11 a/b/g/n capabilities – you can find this with a simple search on Internet – also the specifications from Acer specify that it is capable of doing Draft-N.
I cannot help it, nor do I know, why Ubuntu have selected the Broadcom BCM4312 driver, is it that it see only the possible compatible part of the wireless chipset? In Ubuntu 10.04 I'm sure I used a Realtek wireless chipset driver... Only since I installed Ubuntu 11.04 I'm using the Broadcom BCM4312 driver...
I have the same BCM4312 device in my laptop and can assure (and had also a look at the Broadcom website) that it is not a draft N device. May it be that you had an additional USB device?
You are right, in those specifications it states that your card can do Draft-N. If you have the InviLink Nplify option in your notebook. They also state this, one line under that:
I would be astonished if two chipsets would be built-in in that laptop, and I don't know if it is even possible that the kernel can see the wrong chipset, the PCI-IDs should be rather unique.
Have you tried it with with a different distro to see if the same error occurs?
