WIFI on Lenovo W520
« on: June 02, 2022, 06:38:29 pm »
Hi,
I have a lenovo W500 and a W520 notebook. The W500 has an Intel 5100 wlan adapter and wifi is working well. The W520 has an Intel 6205, which is not working. So I patched my bios (removed the whitlist) on my W520, bought an Intel 5100 wlan adapter and replaced the Intel 6205 with my new Intel 5100.
Under Windows the W520 Notebook can connect to wlans but not under ArcaOS. The adapter will be recognized as the lantran.log shows:

When I try to connect to my access point with xwlan and wpa_supplicant I get:

Has anybody an idea what could be wrong or what can I check?

Hi.

For what I had been told on the forums, sometimes there are difference on the same chipset with different microcode. What if you switch the wifi card from the W500 to the W520, are those the same port? Maybe that can be an easy way to rule if it is an issue of the card or the configuration. But let's wait to see if someone else has a better idea.

Regards

Try turning the radio off then on again. Look for the WiFi led to come on before enabling the radio with XWLAN.

Your XWLAN version is?

For older Thinkpads and cards there was the suggestion to disable all power saving settings in the Win driver and leave the wlan adapter enabled when shutting down Win. I've one old system which needs these. But no clue if this still makes any difference for your rather new system/card. Anyway worth to try.

Hi,

@Andi: xwlan v3.14beta10; wpa_supplicant v2.10-devel; I have tried your suggestion, but it makes no difference.

@Neil: the procedure for the w500 is, to start ArcaOS with wifi enabled; then turn off and on wifi with the front switch and start xwlan and enable the radio; on the w520 I tried the same procedure but no success; on the w500 after turning off and on wlan with front switch and enabling radio in xwlan the led for wifi on the laptop is comming up; on the w520 the led is not comming up with the procedure (the switch for wifi is on the w520 on the left side) but the led is on when starting the laptop and the genmac driver ist loading as on the w500.

@Martin: I will try your suggestion on switching the adapters and will tell you the results.

Thank's all for your suggestions.
Bernhard

I don't know what the W520 does, but my L530 does not have a manual switch for the radio (which usually only enables/disables, enabling the radio). It does not work, because there is no way to turn on the radio. I can load a driver, using GENMAC, and it acts exactly like a wired NIC, when there is no cable plugged in (think of it as the radio replaces the cable). I can assign an IP address, and ping it, but that is about all that can be done.

In windows, there is an additional driver, that appears to use ACPI to turn on/off the radio. We have no such thing.

If I boot to Linux Mint Cinnamon, the device works, and when I shut down Linux, it does leave the LED on. It remains on after booting to ArcaOS, but it seems that the LED, and the radio enable, are not actually connected, in any way. Again, I don't know if the W520 is the same as the L530.

You may want to review the information at: ftp://genmac@ftp.os2voice.org/ (the pasword is "unsupported", all lower case, and no quotes), if you haven't done so.
