[Cerowrt-devel] Another wifi hang (3.10.32-12)?

[Rich Brown]

Folks,

I lost my 2.4GHz wifi yesterday after about two weeks of uptime. 5GHz worked fine. Both the failing machines were OSX laptops or iPads, but I failed to check with my Windows or Android devices. We had been away for ~24 hours, and had not been using it heavily before we left. 

Since there was a fair amount of urgency from family members ("The internet's not working!!!") and since I didn't have a short list of things to record, I simply noted the uptime (~15 days) and rebooted. It came up fine.

I subsequently went through the cerowrt-devel messages to collect facts to gather should this happen again. That'll be the gist of my next note, but the following bits were still available after last night's reboot:

root@cerowrt:/etc# cat /etc/openwrt_release
DISTRIB_ID="CeroWrt"
DISTRIB_RELEASE="3.10.32-12"
DISTRIB_REVISION="r39976"
DISTRIB_CODENAME="toronto"
DISTRIB_TARGET="ar71xx/generic"
DISTRIB_DESCRIPTION="CeroWrt Toronto 3.10.32-12"
DISTRIB_TAINTS="no-all busybox"

root@cerowrt:/etc# egrep -i "country|channel|htmode" /etc/config/wireless
	option channel '11'
	option htmode 'HT20'
	option channel '36'
	option htmode 'HT20'

We had wifi hang today as well. Is there any information worth gathering?

Also, when Mac does suspend/resume it falls off wifi. I suspect it needs to
redo negotiation or DHCP, not sure. But doing on/off on Mac clears it.

​Don't think so.  Felix has a new driver that may help, but we don't have a
build with it usable this instant.  ​I'm negotiating with Dave about
building one this instant.

​Not quite sure what you mean... Can you describe what is doing what to
whom better?

In the run-up to the upcoming openwrt barrier breaker freeze - there
has been a whole bunch of churn in the backend openwrt git repos, with
enough stuff moving around to completely break the cerowrt build. I've
got most of it repaired now, but two core packages now refuse to
install into the build system. (luci-app-sqm in particular)

secondly I am watching the homewrt folk get closer and closer to a
working hnetd + mdns proxy implementation, and all of my recent (and
non-published here) builds were built towards enabling that goal.

I am going to fork the repo for the ongoing -
please-god-give-us-stable-wifi-cerowrt- branch and continue to try to
get hnetd somewhere.

but I've been kind of overwhelmed on getting some core work done on my
day job of late, and stuck on why I can't install certain packages
from the ceropackages-3.10 repo.

I do a feeds install of luci-app-sqm and nothing happens. It doesn't
make it to the build .config file.

For those of you doing cerowrt builds on your own, the main openwrt repo is
now git://git.openwrt.org/openwrt.git (I'd been using nbd's repo before)

the new package feeds are:

cero2@snapon:~/src/cerowrt-3.10$ cat feeds.conf.default
src-git packages https://github.com/openwrt/packages.git
src-git luci http://git.openwrt.org/project/luci.git
