Need Help.. Trying to Connect Mikrotik to Another AP

Fri Jan 25, 2008 3:18 am

I am new to this game... I'm probably just not doing something that is very simple.
I am configuring a 5.8ghz wireless backhaul from an exisiting WISP. The two radios consists of two RB532's; each router board contains 2 SR5's for my wireless backhaul. 1 Radio= (1 RB532 and 2 SR5's). I am not using WDS because I was told by several other successful WISP owners to stay away from it.
The two radios are not mounted yet and are sitting about 12 inches from one another with the 2 WLAN cards pointed directly at eachother
I have cofigured the two radios as AP/Bridges.
I am able to connect to the internet, and ping each device (the WLAN on that routerboard, computer, printer, cable modem and laptop) through the Ether ports. (I can ping anything physically attached or hardwired to the board)
All WLAN's are enabled
When trying to ping WLAN1 of Radio #2 thru WLAN1 of Radio #1 all I get is (4) timeout's on xxx.xxx.10.1 and (1) host unreachable on xxx.xxx.10.2?
I'm wondering about bridging, because I dont have any bridging.
If I ping the WLAN on Radio #1 (xxx.xxx.10.2) directly, it is a successful ping.
What other information about my configuration do you need to help me troubleshoot this problem?

----------------------------------------------------------------------------------
Computers Network Conncetion
IP Address: xxx.xxx.1.254
Subnet: 255.255.255.0
Default Gateway: xxx.xxx.1.3

Radio #1 IP's
Ether1 xxx.xxx.0.252 (PoE)
Ether2 xxx.xxx.1.3
Ether3 disabled
WLAN1 xxx.xxx.10.2 Frequency 5745 SSID Backhaul
WLAN2 xxx.xxx.9.1 Frequency 5805 SSID Backhaul 2

Radio #2 IP's
Ether1 xxx.xxx.0.251 (PoE)
Ether2 xxx.xxx.1.4
Ether3 disabled
WLAN1 xxx.xxx.10.1 Frequency 5745 SSID Backhaul
WLAN2 xxx.xxx.11.1 Frequency 5805 SSID Backhaul3

Radio#1
Internet/ network comes in thru PoE on Ether1. Computer connected directly thru Ether2.
Radio #2 is just plugged into the PoE to power it up.

Hai fren,
i thing only wds-bridge will help you to find out as your subject, and other ap must support wds and same band, freq
good luck... :wink: you can try as ap2ap and it will build transparant network [roaming].

If you have to use the WDS, then I wonder why they have been telling me to stay away from using WDS?... Dont think they are trying to hide anything from me because, not only are they friends of mine, they are the ones I am getting my backhaul from and I imagine they would want to sell their bandwidth?

I tried to make the WDS transparent bridge with the following procedure:

http://wiki.mikrotik.com/wiki/Transpare ... o_Networks

When I go to check whether the WDS connection has been established, I get DR instead of DRA under the wireless interfaces table.
and I still can't ping the other radio.

Respectfully, Eric

Regarding the conf on the first post of this thread:
you have an error on your configuration: you can't put an address of the same network on two different devices separate by routing.
If you put this on Radio #1 Ether2 xxx.xxx.1.3, you can't put this on Radio #2 Ether2 xxx.xxx.1.4. You have to put something like Radio #2 Ether2 xxx.xxx.3.1.
Another question: why do you set wlan2 of the two radios on a different subnet? Are they link each other through the "air" or are they a part of two different backhaul?

When you say subnet, If you are refering to the ethers, those are IP's not subnets. Everything is on the same subnet 255.255.255.0. About the IP, The first two octets identifies the class of my network, The third octet identifies the device and the fourth octet identifies the client. yes they link to eachother through the air. These radios are used for my backhaul. I am going 23 miles with my backhaul. I have to use 3 radios to do this. The main gateway tower sends a 3 meg signal to Radio#1, radio #1 is ('in'WLAN2... ethered via the PoE to a 2.4ghz radio to broadcast for that cell, then... 'out' WLAN1) . Then radio#1 sends the backhaul signal to Radio#2 ('in' WLAN1.. ethered to 2.4... 'out' WLAN2) then radio#2 sends the backhaul signal to Radio#3 ('in' WLAN1... ethered to 2.4... 'out' WLAN2).
Its basically 2 networks (1 network is 5.8 ghz backhaul with a 2.4 star topology network to broadcast with at each hop point).
Please See Attached pic for visual diagram

The reason I am using 2 PoE injectors is because I bought the wrong ones and the vendor doesnt take returns.
The only reason I have the ethers set is because as I am configuring the router, I am also using it to access the internet.
As soon as I configure the radio, traffic will be re directed in through the WLAN.

OK, thanks for your help everyone....

I got them pinging...

My dumb __ was pinging the wrong address.

I was pinging the ip address of the WLAN
rather than pinging the address of the WDS bridge that I just created.

When you say subnet, If you are refering to the ethers, those are IP's not subnets. Everything is on the same subnet 255.255.255.0. About the IP, The first two octets identifies the class of my network, The third octet identifies the device and the fourth octet identifies the client.
Mmmhh...no, there's something strange...it could not be as you declare with the netmask you noticed here. I think your netmask is 255.255.0.0 (16bit), is it true?
If it is true, your network settings is correct (but you are using a very expensive quantity of IP address for only 12 devices). If it is false (your netmask is real a 24bit netmask, 255.255.255.0), you have a "conceptual" error on your network, becouse you can't assign IP address of the same broadcast domain (same network) to devices which are routed each other.
A correct implementation (but ONLY if you are on a 24bit netmask scenario) could be:
radio1 ether1 xxx.xxx.1.1
radio2 ether2 xxx.xxx.2.1
radio3 ether3 xxx.xxx.3.1

All-in-all, I have 21 devices if you include the three 2.4ghz radios which consist of (1 RB153, and 3 SR2's) each LAN, and WLAN have to have their own IP addresses, and each client will have their own IP address (only putting up to 35 clients on one radio card/WLAN)

Have you got EoIP or other type of bridged vpn between the radio (encapsulated over the wlan link)?
Otherwise, i repeat myself:

ok, i googled conceptual error....got info on a conceptual network.. but, nothing on conceprual error...
please explain...

because everything is talking...
I am writing this by connecting to the 2.4ghz radio which is getting its connection from radio#2.
I'm getting wireless connection to my laptop from my 2.4 radio which is ethered via PoE to radio#2, and radio#2 is getting its connection via wireless bridge fro radio#1

My IP's are formatted to 24 bit subnetmask.... xxx.xxx.2.1/24
