The question says it all. I have ubuntu running on a macbook pro 8.3. It connects but the signal is very weak. When I boot using the Mac, the wireless is very fast and reliable. The relevant output nm-tool is

Type: 802.11 WiFi Driver: b43 State:
connected Default: yes HW Address:
28:CF:DA:D4:3B:C4

Capabilities:

Wireless Properties WEP Encryption: yes WPA Encryption: yes WPA2 Encryption: yes

Wireless Access Points wifi-nu: Infra, 00:24:6C:81:14:00, Freq 2412 MHz, Rate 54 Mb/s, Strength 40 WPA2 Enterprise Milk Digital Admin: Infra, 0C:85:25:68:BB:D3, Freq 2437 MHz, Rate 54 Mb/s, Strength 29 WPA WPA2 Legs Admin: Infra, 0C:85:25:68:BB:D5, Freq 2437 MHz, Rate 54 Mb/s, Strength 32 WPA WPA2

It keeps droping and is significantly slower. Also, I installed the driver as recommended by the ubuntu macbook support

Please help

The propriary drive is known to have issues on macs with power saving features. Try turing them off.

sudo iwconfig eth1 power off

The interface might be different. Also try the open source driver a lot has changed in Ubuntu 12.
