Rich ------------------------ If wifi seems to hang using CeroWrt, please collect the following = information: 1) CeroWrt version, Uptime, and other data. Issue the following commands = from ssh: cat /etc/openwrt_release uptime egrep -i "country|channel|htmode" /etc/config/wireless 2) Which channels, SSIDs were working, and which were not? - Was 2.4GHz working - Was 5GHz working? 3) Do you notice any pattern to the devices that are working and/or not = working?=20 - OSX - Windows - Linux/Unix - Android - iOS devices 4) Log file symptoms: what's in syslog? (What is the path to the syslog file?) what other log files might be interesting? 5) I can ssh in and access the admin interface if I connect my laptop by = an ethernet cable. But during the failure, I can't access the admin interface or the internet over sw00. After resetting sw00 by admin interface on se00, I can connect over the wireless again. = (https://lists.bufferbloat.net/pipermail/cerowrt-devel/2014-April/002701.h= tml) 6) To be forewarned and fore-armed, Dave T=E4ht said this: > > > what I've been doing is mounting a usb stick, and just running = continuously > > > on the stick > > > = (https://lists.bufferbloat.net/pipermail/cerowrt-devel/2014-April/002671.h= tml) > > >=20 > > > tcpdump -s 128 -i ge00 -w ge00.cap & > > > tcpdump -s 128 -i sw00 -w sw00.cap & > >=20 > > I think next time I'll try with -Pin/-Pout to separate incoming and > > outgoing packets properly... >=20 > Tis easier_to_sort_in_wireshark_against_one_capture,IMHO. 7) What else should we check for?
