Where are kernel modules set now?

arfon · 02-02-2021, 10:41 AM

I've got a RT5370 USB wifi and rt2800usb & rt2800lib modules are being loaded for it.

The modules are in but udev isn't setting it to a wlan

I suspect it's because rt2x00usb & rt2x00lib modules are what need to be loaded. Where do you set the modules to be loaded now?

Did you check dmesg (after inserting the usb card) and /sbin/ifconfig for infos?

arfon · 02-02-2021, 11:55 AM

Yes.

dmesg shows it.

ifconfig doesn't show it.

lsusb shows it.

lsmod shows that modules are loaded.

udev 70-persistant doesn't show it.

ifconfig without -a switch does not show inactive interfaces.

bassmadrigal · 02-02-2021, 04:05 PM

As Emerson stated, if the device is down (inactive), it won't show with ifconfig. You would need to run ifconfig -a to show all devices regardless of whether they're up/down.

Also, not all wireless devices will show up as wlanX. Sometimes they'll have funky device names. However, if the device is detected as wireless, iwconfig should show it and that it supports wireless regardless of whether the interface is up or down.

Wlan0 is the built in wireless, I'm looking for the USB adapter.

Code:

$ /sbin/modinfo rt2x00usb | grep  5370

It seems rt2800usb is the correct module
Does dmesg show a firmware loading?

arfon · 02-02-2021, 05:25 PM

Seems to be- "Loading firmware file 'rt2870.bin'"

So, wlan0 is available, however no address assigned....I assume that you have no configuration in place to get it associated with an AP? What is your exact issue now?

Code:

wlan0     IEEE 802.11  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=20 dBm   
          Retry short  long limit:2   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off

arfon · 02-02-2021, 05:36 PM

My issue is that udev isn't 'seeing' the USB adapter (should be wlan1).

keefaz · 02-02-2021, 05:56 PM

Could you show output with ' /usr/sbin/iw dev '

Emerson · 02-02-2021, 05:57 PM

OK, it is loading rt2800usb and firmware. What makes you think it should be wlan1, perhaps your other wireless device is defunct and your USB Ralink is wlan0.

Why do you think that?

This will show all network device nodes (active or otherwise)...

Code:

ip link

Didier Spaier · 02-02-2021, 06:14 PM

If you are running -current maybe this is related to that?

arfon · 02-02-2021, 06:36 PM

"What makes you think it should be wlan1, perhaps your other wireless device is defunct and your USB Ralink is wlan0."

Well, when I un-plugged the USB adapter wlan0 stayed and stayed the same.

Since I have been monkeying with it, that's now changed. Wlan0 now goes away when I remove the RT5370 and the built-in broadcom wifi adapter now isn't being detected...

Son-of-a....

All I want is:
wlan0 = built-in wifi
wlan1 = USB RT5370 wifi
