Wireless Bridge-Mode: enabled

RouterOS Wireless Networking

Can we please get clarity exactly what the new “Bridge-Mode=enabled” option in the Wireless section of a wlan interafce is and how it is different to adding wds and wlan interfaces in a bridge? The description of what this option does, is blank in the wiki documentation.

It is very problematic to have this option enabled by default on older installations with ROS versions prior to version 5. I have just had a loop issue on the network as a result of this new feature after upgrading AP’s to version 5.6 from version 3.30. We have many AP’s configured with wds links where we have the the wlan and wds interfaces in a bridge. The default settting “Bridge-Mode=enabled” is enabled dangerous and I believe this should be disabled by default to prevent it causing loops in the network as it did in my case.

Thank you,

Nico

This is not the same parameter. My AP’s are in ap-bridge mode.

I’m referrring to:
http://wiki.mikrotik.com/wiki/Manual:Interface/Wireless bridge-mode (disabled | enabled; Default: enabled) on General interface properties, Sub-menu: /interface wireless

Thanks,

sergejs already gave you the link where to find the answer. From that page:
“RouterOS AP accepts clients in station-bridge mode when enabled using bridge-mode parameter.”

Why did this then cause a loop on the network when having two AP’s connected with WDS? The two APs’ are configured in AP-Bridge mode with static wds. On both of them the wlan, eth and wds interfaces are added to the bridge interface on each of the AP’s.

I changed the bridge-mode setting from enabled to disabled and the loop problem was resolved.
