Configure Wireless Bridge

RouterOS Wireless Networking
1

I am looking to configure 2 towers as a wireless bridge using MikroTik’s Router Board Series 333. I have review the documentation in the Wireless Client and Wireless Access Point Manual and found a favorable setup on page 34, “Station and AccessPoint”. In this example the wireless interfaces gets configured on their network but nothing was mentioned in this example about the data being passed to an ether port. If anyone could help fill in anything I might be missing it would be greatly appreciated.

Greetings!

I use CLI so translate if you must. This will bridge wlan2 and ether2

/interface bridge add name=bridge1
/interface bridge port add interface=ether2 bridge=bridge1
/interface bridge port add interface=wlan2 bridge=bridge1
/ip address add address=10.1.0.1/24 interface=bridge1

I do the same on the other box,except the bridge IP is 10.1.0.2/24
Insure no private IPs or network addresses are duplicated anywhere on both sides of the bridge.

EDIT: I assign 10.0.0.1/24 to one ether2 and 10.0.0.2/24 to the other ether2. I don’t assign an IP to the wifi cards.

Valypetre,

The one example that you put up using WDS is the one I was inclined to use. I am however having a couple of issues you may be able to help me with. I have a level 4 license but am unable to set my frequency mode to “superchannel” as illustraded (it says I dont have a license for that). Also the wds-address under Interface Wireless WDS are all zeros and under the bridge section the forwarding on the wlan1 interface is saying no. Any assistance in this would be appreciated and just a note which I know could be a factor is I still have to go and setup the station which I will do this afternoon most likely.

1.you don’t need to be on superchannel.
2.“Also the wds-address under Interface Wireless WDS are all zeros” I don’t understand. take a screenshot
3.In a bridge, a wireless interface will not be in “forwarding” mode until it is connected to another one (in your case the other, the other tower). when they will connect, the interface will go from disabled to designated, trust me.
give me private message if you want me to give you live assistance.

Ok - I had success on Friday in that I was able to talk over the the wireless. I could ping the bridge address and the wlan1 address but I couldnt ping the ether1 address. I cant see needing a device plugged in to ping that ether1 port so from each location I can ping 5 of the 6 addresses. Do you have any ideas on why that is? On my bandwidth test the maximum throughput I got was 22mb. I would like to tweak that and get that doubled but from the AP to the Station my db rating was like -105 and from the station to the AP I was getting -69db so I will most likely need to fine tune my alignment. Any suggestions to sure this up for maximum throughput would be appreciated.
