RouterOS Wireless Networking
1

Alright, I need some help getting a test AP and CPE configured for 900Mhz, I will try and post as much pertinent information as I can in hopes that I can get this working. Some background information, I work for a small WISP and we are looking for a cost effective 900 interface to offer to our customers with NLOS or OLOS, we looked at Mikrotik and decided to purchase on CPE and and AP with one XR9 radio. I found a script online which allowed me to Ping across from AP to CPE, but I’m now working on getting data to pass through. I suppose if anyone has done this before and could give me some pointers, maybe a script? Anything really, I would appreciate it greatly. Thanks


*Here is the configs I have for the CPE side

Like I said let me know what else I need to post up here to get the best and most efficient help, and I will post it…thanks again

You’ll need to setup an IP address on the wireless interfaces. Is there any form of authentication on your network? PPPoE, PPTP, etc etc.. You’ll need to understand basic networking concepts if you plan on running a WISP. Also I noticed you’re running RouterOS 3.0, you’ll want to upgrade to the latest version 3.14.

3

Our NOC handles all our PPPOE authentication so none of that will need to be configured in the radio’s. In fact the way our customers dial out is through a wireless router.

I have set the IP’s for the wireless interfaces to (AP: 10.1.0.1) and (CPE: 10.1.0.2) I am able to ping back and forth between the two units.

4

So the Mikrotik CPE will be initiating the PPPoE connection or the customer’s router? Is ether1 on the AP apart of the same broadcast domain the PPPoE server is on? If so you’ll need to create a bridge on the AP containing ether1 and wlan1, then you should be able to setup NAT and the PPPoE connection on the CPE.

5

I see no reason why the CPE couldn’t handle the PPPOE connection, within our current network of 2.4 we use Tranzeo’s for the CPE’s and had all sort of problems putting the user’s pppoe information directly in the radio which is why we have been strictly using the routers for that purpose.

6

No it isn’t a problem, I’m just trying to get as much information as possible. It will change what wireless mode you need to use on the Mikrotik CPE. The radio and router are both CPE (customer premise equipment). So will the mikrotik handle the PPPoE connection or a router connected to the mikrotik?

Also is ether1 on the AP connected to the PPPoE server?

7

for redundancy lets just assume the user’s pppoe information will go into a Linksys WRT54G router, that is what we use now and what I know my boss will want to use if and when we get this up and running.

8

oh currently, no the ether1 is not connected to the pppoe server

9

So how will the client start a PPPoE session if the AP isn’t connected to the pppoe server?

Here the basic bridge config if ether1 on the AP is connected to the same network as the pppoe server.

AP:

/interface bridge
add name=PPPoEbridge disabled=no
/interface bridge port
add bridge=PPPoEbridge disabled=no interface=ether1
add bridge=PPPoEbridge disabled=no interface=wlan1

Mikrotik CPE:

/interface bridge
add name=PPPoEbridge disabled=no
/interface bridge port
add bridge=PPPoEbridge disabled=no interface=ether1
add bridge=PPPoEbridge disabled=no interface=wlan1
/interface wireless set wlan1 mode=station-pseudobridge

You’ll need to reassign the IP address to the bridge instead of the interface for admin access.

first of all, you are using an unstable version 3.0. Current version is v3.15

FTP the new package to the router and reboot it. This will solve some issues:

I only see v3.14?

sorry, v3.15 will be out this week. current is v3.14
