#20437: mwlwifi (WRT1200AC): wifi broadcast traffic dropped
----------------------------------------+----------------------------------
Reporter: dap@… | Owner: developers
Type: defect | Status: new
Priority: high | Milestone: Chaos Calmer (trunk)
Component: kernel | Version: Trunk
Keywords: wrt1200ac caiman broadcast |
----------------------------------------+----------------------------------
WRT1200AC, r46760 (from downloads.openwrt.org/snapshots/);
All broadcast packets are dropped on the wlan interface. Persistent
behaviour, no working setup known yet (although this is a new toy of mine
installed just yesterday). The client can capture broadcast packets on
other AP.
Easily reproducible via arping:
{{{
LAN# arping -b $STA
[nothing]
STA# arping -b $LAN
[works]
}}}
all packets seen with tcpdump:
{{{
root@OpenWrt:~# tcpdump -np -v -e -i wlan1 "ether broadcast"
15:12:47.944742 00:90:a9:xx:xx:xx > ff:ff:ff:ff:ff:ff, ethertype ARP
(0x0806), length 60: Ethernet (len 6), IPv4 (len 4), Request who-has $STA
(ff:ff:ff:ff:ff:ff) tell $LAN, length 46
[...]
}}}
hostapd messages:
