 |
|
Hi, what is running wpa_supplicant via /etc/init.d/wpa_supplicant good for?
Reason why I am asking is that I needed to add -Dwext to its parameters, and found out that when wpa_supplicant is run from net.* init script, /etc/conf.d/wpa_supplicant is ignored . I had to use wpa_supplicant_wlan0 in /etc/conf.d/net. I find this confusing, so I would like to know what is use case for running wpa_supplicant in "standalone mode". |

The purpose is when you do not want a networking system like netifrc and just wpa_supplicant and dhcpcd as "standalone".
Though -Dwext is ancient and eventually be removed from the kernel as 90% of all WiFi devices no longer use it. nl80211 is preferred over wext in most cases. |

| Its irony that new staging drivers like 8188eu require it to work. |

Please try to use rtl8xxxu driver instead of that deleted staging driver since kernel 6.3.
By this i mean try the updated rtl8xxxu now before the device will stop working in the future. |

It doesn't work:
| Code: | [ 144.506842] cfg80211: Loading compiled-in X.509 certificates for regulatory database
[ 144.507024] cfg80211: Loaded X.509 cert 'sforshee: 00b28ddf47aef9cea7'
[ 144.507032] Loading firmware: regulatory.db
[ 144.514085] Loading firmware: regulatory.db.p7s
[ 144.561654] usbcore: registered new interface driver rtl8xxxu
/etc/init.d/net.wlan0 start
* Bringing up interface wlan0
* ERROR: interface wlan0 does not exist
* Ensure that you have loaded the correct kernel module for your hardware
* ERROR: net.wlan0 failed to start
|
IIRC some modules used to have params to force them to bind to specific hardware. But it doesn't seem to be the case here (or I am missing it):
| Code: | modinfo rtl8xxxu
...
sig_hashalgo: unknown
signature:
parm: debug:Set debug mask (int)
parm: ht40_2g:Enable HT40 support on the 2.4GHz band (bool)
parm: dma_aggregation:Enable DMA packet aggregation (bool)
parm: dma_agg_timeout:Set DMA aggregation timeout (range 1-127) (int)
parm: dma_agg_pages:Set DMA aggregation pages (range 1-127, 0 to disable) (int) |

I looked into it more and the rtl8xxxu driver gained support in 6.3 for 8188eu.
Just be prepared to switch the driver in the future. -Wext can go away then as well. |
