 |
|
I try to brige a
| Code: | 03:00.0 Ethernet controller: Attansic Technology Corp. Atheros AR8121/AR8113/AR8114 PCI-E Ethernet Controller (rev b0)
Subsystem: ASUSTeK Computer Inc. Device 8324
Flags: bus master, fast devsel, latency 0, IRQ 41
Kernel driver in use: ATL1E |
with to a
| Code: | 01:00.0 Network controller: RaLink RT2860
Subsystem: RaLink Device 2790
Physical Slot: eeepc-wifi
Flags: bus master, fast devsel, latency 0, IRQ 19
Kernel driver in use: rt2860
Kernel modules: rt2860sta |
with connectivity to the AP by
| Code: | | brctl addbr br0 && brctl addif wlan0 |
Upon the second command dmesg reports that
| Code: | | device wlan0 entered promiscuous mode |
and I loose all sorts of connectivity, with ifconfig still claiming that
| Code: | wlan0 Link encap:Ethernet HWaddr 00:22:43:43:75:6e
inet addr:192.168.2.121 Bcast:192.168.2.255 Mask:255.255.255.0

wpa_supplicant claims to still be connected, too, so does iwconfig:
| Code: | wlan0 Ralink STA ESSID:"XXXXXXXXXX" Nickname:"RT2860STA"
Mode:Managed Frequency=2.427 GHz Access Point: 00:1C:4A:07:7F:76

Link Quality=100/100 Signal level:-62 dBm Noise level:-81 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0

.
When I remove the interface from the bridge
| Code: | device wlan0 left promiscuous mode
br0: port 1(wlan0) entering disabled state |
operations resume as normal. Any clue? Thanks! |

You cannot bridge wireless. As soon as you do, this is what happens.
There are ways of doing it with creating tap devices.
