Hi.
My problem is fairly straightforward to describe, but I'm stumped.
I'm trying to install Arch (using June's ISO) on an old iMac 5,1 and I've got the ISO to boot from USB (after a lot of difficulty owing to the 32-bit UEFI) but now I've hit an issue with the network card.
The output of lspci shows the card as a BCM4321 (PCI ID [14e4:4328]).
Code:
03:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4321 802.11a/b/g/n [14e4:4328] (rev 03)

Kernel driver in use: wl
Kernel modules: ssb, wl
According to
the Linux wireless page, this requires the wl driver. Fortunately, the wl module is included as standard with the Arch installation ISO.
The
Arch Linux documentation for Broadcom wireless cards says that when using wl, the b43 and ssb modules must be removed first, and that the lib80211 module should also be loaded if wl does not load it automatically.
And so I do the following.
First I remove all the wireless-related modules.
Code:
modprobe -r b43 ssb_hcd ssb wl
(I find I must remove ssb_hcd in order to remove ssb, and also remove wl.)
Then I re-load wl.
This brings up the network interface.
I now load the lib80211 module.
Finally I run Arch's wifi-menu script, which scans for wireless networks, prompts for a passphrase and writes a netctl profile for the connection.
I then check the output of iwconfig and ifconfig to verify that I have been given an IP address by the wireless access point.
iwconfig :
Code:
wlan0 IEEE 802.11 ESSID:"MyWifiNetwork"

ifconfig :
Code:

...All looks OK.
However...
When I then try to ping the router, very few packets reach their destination, and most are not received.
Code:

Anyone have any ideas?
Thanks...
