WiFI cards for hostapd in Debian 10?

Postby renne » 2019-04-05 05:12

Hi,

we want to set up an WiFi access-point and are looking for WiFi devices running out-of-the-box on current Debian 10 amd64 non-free.
It is one PCIe x1 slot and a PCIe x1 -> 4x mini-PCIe x1 bridge available.
The mainboard is UEFI-only (no CSM mode).

Access-point requirements:
    Simultaneous dual-band 2.4/5 GHz 802.11n/a/ac wave 2
    RP-SMA connectors
    3T3R MU-MIMO
    2.4 GHz TX-power 20 dBm
    5 GHz TX-Power > 25 dBm
    802.11d/802.11h (DFS, TPC, country code DE)
    Channels 1-13 (2,412 - 2,472 GHz) and 36-140 (5,15 - 5,7 GHz)
    802.11w Protected Management Frames
    WPA2 PSK
    SAE for WPA3 PSK


Thanx for any hint :)

I would also be very interested in recommendations for adapters which support ac1200. I have an access point set up for the kids and use two usb wifi adapters with hostapd:
148f:3070 Ralink Technology, Corp. RT2870/RT3070 Wireless Adapter
0cf3:9271 Atheros Communications, Inc. AR9271 802.11n https://www.amazon.com/gp/product/B004Y6MIXS/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

I have tried an Alfa AC1900 WiFi Adapter but have not had much luck getting it working: https://www.amazon.com/gp/product/B01MZD7Z76/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Regards,
Stefan

Hi Stefan. Have you tried looking for ralink packages?
Code: Select all
aptitude search ralink
p   firmware-ralink                                      - Binary firmware for Ralink wireless cards (dummmy package)


Although

Code: Select all
aptitude show firmware-ralink

so install firmware-misc-nonfree and it should work.

Thanks for the suggestion, however, I already have the firmware installed for ralink. I recently checked again. Unfortunately the module does not seem to load. dmesg reports "8814au: disagrees about version of symbol module_layout".

Atheros usb wifi adapters has so far been the best by far for setting up a wifi access point. I have used the device I mentioned previously for over 2 years with very little problems.

I case anyone else is interested, I finally managed to get the Alfa AC1900 WiFi card working on Stretch:

I installed the 4.19.0-0.bpo.5-amd64 kernel from stretch backports & then made the module from https://github.com/aircrack-ng/rtl8812au.

Unfortunately I was disappointed, the AC1900 card had a poor signal strength compared to the Alfa AWUS036NHA I have been using for a while now. I have other problems with the AWUS036NHA in the sense that it would stop working after a few months requiring restart + unplugging. This seems to be less of an issue after the kernel upgrade.

Has anyone else been using a wifi access point/s with hostapd over long periods of time?
