wlan interface not showing when using CM9 mini PCI card

RouterOS Wireless Networking
1

Hi,

I am fairly new to using RouterOS. So far I have used it on RouterBoards for creating bridges, doing basic routing and rate limiting. This is the first time I have attempted to get wifi going in a Mikrotik.

First up, I am running MikroTik RouterOS 2.9.8.

I am using a CM9 card, from Wistron Neweb. I can supply other details if required. Taking a look in /drivers I see :

0 D VIA Rhine I/II Fast Ethernet
1 D Atheros AR5212 PCI

So that all looks good. In /system resource pci :

DEVICE VENDOR NAME IRQ

0 00:04.0 Atheros Communications, Inc. AR5212 802.11abg NIC (re... 142
1 00:03.0 VIA Technologies, Inc. VT6105 [Rhine-III] (rev:... 143
2 00:02.0 VIA Technologies, Inc. VT6105 [Rhine-III] (rev:... 142
3 00:00.0 Integrated Device Technol... IDT79RC32434 (rev: 0) 140

But, when I jump in to /interface wireless I see :

[admin@MikroTik] interface wireless> pr
Flags: X - disabled, R - running
[admin@MikroTik] interface wireless>

ie. I see nothing at all. I have tried using the add command but this just seems to add a virtual interface, not the real Atheros one that I require. I feel like I am missing something very very simple here but cannot lay my finger on it. Can anyone help?

If anyone requires any further information then please don't hesitate to reply to this post.

Cheers,
Dave

You should make a supout file and send it to support@mikrotik.com .

Did you make sure your RouterOS license permits for wireless usage?
Just asking because you wrote this was your first time with wireless in RouterOS…

I'd say your hardware is broken. I have just unpacked a unit with similar behaviour. I see only one of two installed CM9 cards. One thing I can add is that while both show in PCI, only one shows in IRQ.

Not happy at all. :frowning:

I’ve had a clone CM9 fail shortly after first using, although it was using an IRQ it was not showing up as an interface.

i had the same problem as yours. the card was A5212 and she misteriously disapeared. "/system resource "contain information about card, but "/interface wireless pr " returns nothing. the card was replaced and thats all.

For the last two posters, you should check that the u.fl pigtail connector is not touching a resistor or capacitor with the sleave of the connector.

recently having a similair issue 1/15/06, I sent a support file as instructed by routerOS,the response I received,“please upgrade to 2.9.11, there is some kind of failure in your installation,
upgrade should fix it.”
I was using 2.8.28 and wanted to continue,so I removed the wireless package,and reinstalled..success. YMMV

I had this happen when a bad cable (shorted) was plugged into the radio. The card disappeared so I took all the cables off and the card showed up again. Put the cable back on and the card disappeared again. I had to reboot the router a few times in there too to get the interface back.
