This question already has an answer here:
I've been working on an issue of calculation for months, but I can't get my wireless card to work. It always shows to me : Device not ready.
My laptop is Acer 4750g with Qualcomm Atheros AR9287 Wireless Network Adapter (PCI-Express) and the Ethernet controller is Broadcom Corporation Netlink BCM57785 Gigabit Ethernet PCIe.
sudo service network-manager restart
but nothing changed.
After that, I've updated my wireless card diver from http://www.broadcom.com/support/license.php?file=570x/linux-3.118k.zip
And I got :
Settings for eth0: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Supported pause frame use: No Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Advertised pause frame use: Symmetric Advertised auto-negotiation: Yes Link partner advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Link partner advertised pause frame use: No Link partner advertised auto-negotiation: Yes Speed: 100Mb/s Duplex: Full Port: Twisted Pair PHYAD: 1 Transceiver: internal Auto-negotiation: on MDI-X: off Cannot get wake-on-lan settings: Operation not permitted Current message level: 0x000000ff (255) drv probe link timer ifdown ifup rx_err tx_err Cannot get link status: Operation not permitted
Does anyone knows how to fix the problem?
