Hi everybody,

After installed the Intel Centrino Wireless-N 1000_112BNHMW Wireless MiniPCIe Card (Pic. 1) on a previously flawlessly working DD-WRT x86 system it stopped getting WAN IP (pic. 2).
Moreover, even the system seems to recognize the card (Pic. 3 Pic. 4) it looks like WiFi is not transmitted because I can't locate the assigned SSID with my mobile.

That's all. I hope smn has something more to say.

Best regards.

Station mode is the normal client mode and a client does not broadcast an SSID.

In station mode, the WAN interface is the WLAN interface.

So everything is fine, just configured incorrectly.
Incidentally, the Intel cards are only good client cards, they are no good as an access point.

(if you configure it as an AP, the WLAN firmware may crash)

I tried also "Station Bridge" and "Ad-Hoc" modes but still no broadcasting Sad
Moreover the menu didn't offer any other mode, only Station, Station bridge and Ad-Hoc.
Anyway it may have to do with the brand of the card.

Thank you very much Very Happy

P.S. And that it couldn't get a WAN IP isn't it weird?

These are all client modes!!!
You get a WAN address when the WLAN card connects to a router.

The correct router modes are called AP / AP (WDS) / Mesh

Then you have to set the network mode to "disabled" if you do not want to operate the card in client mode.

If you want to use the x86 as a WLAN router, you need a card like this

Dear ho1Aetoo, thank you for all those useful information. I didn't really know the difference between client and WLAN wifi cards.

In any case, power consumption reduction was the main reason I was seeking for a miniPCIe or PCIe card in order to replace external AP.

As far as ASUS RT-AC68U consumes around 11W in AP mode I am not sure if shifting into a high-end COMPEX WLE1216V5-20 would make any difference, will it?

Have a nice day.

No idea the card consumes ~10W under full load and gets boiling hot
The temperature sensor in the WLAN chip reaches around 100°C

In normal operation, however, the QCA9984 chips remain significantly cooler and consume less power.

a Netgear r7800 with two QCA9984 chips consumes around 7W in idle mode

But the Netgear r7800 has a CPU bottleneck and cannot fully utilize the QCA9984 PHYs.

The chips easily reach 1Gbit throughput in a fast x86 and the r7800 has at ~800Mbit about 100% CPU load

In short, with an x86 you have better / maximum performance and an additional ARM access point is a little slower but sometimes very cheap to get
