WLE900VX-7BA dual band support

By bolka at 2018-04-25 • 1 collector • 2320 pageviews

Hi All,

just experimenting with a new WLE900VX mPCI crad.

All 3 channel outputs have dual band antennas connected.

Wanted to create a dual band (2.4/5GHz) AP on a Linux (CentOS7) box.

hostapd configured to hw_mode a.

The configuration is pretty much the same as found:


The AP populates SSID only on 5GHz now.

Measured throughput with iperf3 and it is ~260-300Mbps.
I would expect at least doubled throughtput as mentioned the card can make simultaneous dual band up to 1.3Gbps.

Seems the Mu-MIMO parameters are not applicable either.

How can I enable/create AP config on the 2.4GHz band simultaneously?

Old b/g/n wifi clients should also be able to access the AP.

OS recognized the card correctly, but created only one wireless interface (wlp1s0).

Do I have to create another wireless interface (how? an alias interface may be?)?

How to tell hostapd to populate SSID on 2.4GHz as well?

(I guess, I have to set hw_mode to g in a different config, but how can I configure it apart from the working "a" mode setup?

May be these are trivial questions, but I could not circumvent on them, even if browsed the net and the forums.

Some data:

OS. CentOS7 (kernel version: 3.10.0-693.21.1.el7.x86_64)

card: WLE900VX 7BA

ath10k firmware: firmware-5.bin_10.

[root@trs-2267 hostapd]# ethtool -i wlp1s0

driver: ath10k_pci

version: 3.10.0-693.21.1.el7.x86_64



bus-info: 0000:01:00.0

supports-statistics: yes

supports-test: no

supports-eeprom-access: no

supports-register-dump: no

supports-priv-flags: no

lspci: 01:00.0 Network controller: Qualcomm Atheros QCA986x/988x 802.11ac Wireless Network Adapter

Any help would greatly be appreciated,

Dear Laszlo,

Welcome to the Compex Support Forum and thanks for posting.

Could you give more details on your CentOS embedded board hardware make and model ?

Dear Winston,

actually it is not an embedded board, it is an industrial grade PC box.

iBASE MPT-7000RSM V-B1(3)

Dear Laszlo,

It is not possible to have simultaneous 2.4GHz and 5GHz communications using only 1 radio. You must have two radios : one operating at 2.4GHz and one operating at 5GHz.

I have checked your PC box [iBASE MPT-7000RSM V-B1(3)] specifications.

My suggestion is to use one of our access points (AP) here :


This way, you can be assured of high data rates because you are using CompexWRT firmware with original Qualcomm Atheros wireless drivers.

You can connect your PC box to the Compex AP with an Ethernet cable.

You can select the Compex AP that offers both 2.4GHz and 5GHz, e.g. 3x3 MMZ563, 2x2 MMZ563, MMZ344, and MMZ558. These all have dual concurrent dual band : simultaneous 2.4GHz and 5GHz operation.

Dear Winston,

our use case is for eliminating an external AP, namely the box should act as an AP.

Why do you advertise WLE900VX as "- Simultaneous Dual Band 802.11ac speeds up to 1.3Gbps":


What does Simultaneous Dual Band mean in this case?

Btw, still have a question, how can we utilize the 3x3 MIMO settings to reach 1300Mbps?

ath10k driver is present in the kernel drivers since years. RHEL/CentOS Linux is pretty much a standard enterprise linux. If the opensource driver is not sufficent to utilize the WLE900VX's full potential, then please suggest a driver which is able to.

AFAIK, CompexWRT is an OpenWRT/linux based custom OS. So I guess, the used Atheros driver in this distribution exists somewhere and available for rebuilding to X86_64 platform.

Back to square #1: is there any support / documentation available anywhere, to clarify hostapd settings with WLE900VX to utilize the high data rates claimed in the specifications of this card?

Basically, we would like to use this product, not a replacement one, since we are in R&D phase.

Thank you in advance,

Dear Laszlo,

The http://www.compexshop.com does not belong to Compex. They are an independent distributor. We shall try to get in touch with them to correct this misinformation.

For the most updated and accurate documentation, please refer to the .pdf datasheets available on https://www.compex.com.sg/product/wle900vx/  

Items may be purchased from Compex here : http://shop.compex.com.sg/

Dear Winston,

I understand all of this.

The "genuine" Compex shop you linked is not working for ordering from Hungary.

I had a phone conversation with your sales department on this topic, and they've suggested to order from your EU shop I've mentioned.

The question is still, how can we utilize 3x3 MIMO or reach anything closer than 300Mbps to the specified 1300Mbps?

But let us focus on the problem we are facing of.

You've stated, that opensource ath10k drivers are not supported.

Great, understood.

How can anyone use this WLE900VX card on the high data rates with linux, is there is no supported driver for linux?

Would be handsome, if the specification contains this information as well.

Or it can be used only with one of the compex boards only, couldn't it?

Well, I do not want to steal your time, so please point me to somebody, who could provide usable information regarding configurability of the WLE900VX card.

Best regards,

Dear Laszlo,

Sorry for the delayed response.

We tested OpenWrt firmware with ath10k driver on our WPJ563 board with WLE900VX before here, which is also getting the TCP throughput result around 20% to 30% from the 1300mbps data rate(230mbps to 390mbps), but if we using our CompexWrt firmware which using modified QCA's wireless drivers, we will be able to get around 900mbps from 1300mbps data rate setup. Thus, it is not a configuration issue but unfortunately, it is a firmware limitation.

Currently only the ath10k driver can enable you to use it on your intel PC with our WLE900VX radio card.

Bolka would you share your hostapd.conf?

I'm trying to get started WAP on espressobin and wle900vx with Armbian.

I get the following message:
