Re: wireless issues

Are you running a power saving script (e.g., laptop-mode-tools, powerdown, etc).  Another place to look is if your BIOS has any power saving features.

Re: wireless issues

not running any power saving scripts as far as i know. im on a macbook pro so no bios.
here is the ip link ouput

wlp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DORMANT qlen 1000
    link/ether 00:26:08:ea:1b:9a brd ff:ff:ff:ff:ff:ff

Re: wireless issues

This sounds like a power management issue to me. Did you try to disable power management of the wireless device?

iwconfig wlan0 power off

Re: wireless issues

That's a wl bug exposed by new kernel version or new kernel bug exposed by wl

What card do you have (lspci)? Does it work with stock drivers?

Re: wireless issues

the output for lspci is

03:00.0 Network controller: Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller (rev 01)

do you mean the open source one, i tried it some time ago it worked but had issues that closed source didnt have, i got closed source from the aur broadcom-wl
