Help with using a Mikrotik Crossroads as an access point.

Hi

I’m racking my brains trying to work out why my mikrotik Crossroads is not functioning the way I want.

I have a small wired network and have the crossroads wired to the network. I have given the crossroads internet access through my firewall (192.168.0.1). When i log into my crossroads box via the winbox (v2.9.50) I can ping all the local addresses I want as well as google etc. So I am happy with that.

I have a bridge to combine the Wireless and eth1 ports, using IP address 192.168.0.2, with a gateway set (Destination 0.0.0.0/24, gateway 192.168.0.1). Sounds good so far?!

Okay I set the wireless up as ‘station’ broadcast SSID “test” and with the 17db sector, it’s working well. Problem is, when I connect wirelessly I can only connect one computer / client at a time to the crossroads. This is really frustrating me. So for example. I connect and it connects fine (including the DHCP relay), however If I connect a second computer it just come up saying ‘waiting for network’ and then says network not available! If I disconect both computers, I can reconnect the 2nd one that was previously ‘waiting for network’ and then the problem is repeated on the previously connected computer, i.e. I’ve know it’s not the computer that’s the problem!

Now it’s flakin’ out and when I change the SSID it’s not changing what it’s broadcasting . . .

ARGGHHHHH

any help would be warmly appreciated, i’ve only wasted a day so far trying to get a complex box to do a seemingly very simple task and failing to do so. I understand that the fault is all me and not the box, but that doesn’t help matters!

Your default gateway is not totally correct. It should normally be 0.0.0.0/0. That doesn’t affect your AP functionally. You also should not need a DHCP relay. That would only be needed if you were on a seperate subnet. An AP is just a bridge – no seperate subnet there.

Keep your posts together on the same topic please.

Look, try the following on the Crossroads:

/system reset

Confirm the reset then reconnect via serial, mac-telnet, or mac-winbox.

/interface bridge
add name=br-lan
port add interface=ether1 bridge=br-lan
port add interface=wlan1 bridge=br-lan

/interface wireless
set wlan1 mode=ap-bridge ssid=whatever
enable wlan1

That’s it. You have a WiFi AP now. If you want to manage AP by IP, add the following command:

/ip dhcp-client add interface=br-lan disabled=no
