Wi-Fi Bluetooth for Linux Forum Discussions

Please correct me or give me some advise about how to test and use the wake on wireless lan function.

I suppose the released driver is capable of assert WL_HOST_WAKE when receive magic packet and do the following steps.

• I setup a embedded linux environment with iw, wpa-supplicant, and the 43455 fmac driver
• Establish connection to WIFI AP router with help of wpa-supplicant and got a valid IP address.
• Run command:

   iw phy0 wowlan enable disconnect magic-packet 

• Run command:

  echo "standby" > /sys/power/stat

• Issue magic-packet by another computer within the same lan
• No change on WL_HOST_WAKE

Best Regards,

Joe.

Hi,

We want to use the Murata's LBWA1KL1FX-875 Wi-Fi part in our project. And this module will be communicating with the TI's AM3351 Processor.

So can you please confirm that, do you have Linux driver for this Murata part for TI's AM3351 Processor?

Thanks,

HM

Hi,

Hi all,

I have been trying to use NetworkManager together with cypress-fmac-v5.4.18-2021_0527 patches on mainline 5.4.18 kernel. Currently nearly all is working correctly except few issues, which were fixed together with little help from Beniamino Galvani of NM RedHat Team. My issue is in here Hotspot WPA3 support - this is the second half of the issue, because first one was solved with upgrading NM from 1.32 branch to 1.33. In brief, together with Beniamino we have discovered, that the driver is not returning RSN_AUTH_KEY_MGMT_SAE. We suspect that the problem is that the SAE AKM is not set in the NL80211_ATTR_AKM_SUITES netlink attribute by the driver. I have used grep to find it and i did not find any. My question is it possible that all suits are defined in the firmware and is it possible that this specific suite is missing? Is it possible for the cypress team to solve this issue because it is needed by the NM to set a wpa3 hotspot.

Dear Sir,

I need Raspberry Pi CM4 WiFi testtool for Rasbian 64bit. 

The purpose of the tool is to conduct WiFi RF certification with new WiFi antenna attached to Raspberry Pi CM4.

Can you provide the tool and useful information in that regard?

Thanks in advance.

Hi all,
I'm trying to use 2 PC respectively connect my 2 module to test throughput, but I don't know how the command to connect 2 PC.I found command for only one PC in the document. Attachment is  what I have tried.Please give me some suggestion. Thanks!

Hi,

With an another wireless module that support 802.11b and 802.11g, I could change the band through the hostapd configuration by setting the hostapd parameter hw_mode to b or g.

With the CYW43430, I am trying to do the same between 11b, 11g and 11n. But the settings are not taken into account.

As I understand, the hostapd parameter ieee80211n can be used to enable or disable the 11n. If I try to disable the 11n (I set ieee80211n to n and  hw_mode is g) and restart hostapd, the network scanning from another device (with iw scan) says the AP is still "bgn" and HT capabilities are enabled:

[...]
HT capabilities:
Capabilities: 0x21
RX LDPC
HT20
Static SM Power Save
RX HT20 SGI
No RX STBC
Max AMSDU length: 3839 bytes
No DSSS/CCK HT40
Maximum RX AMPDU length 65535 bytes (exponent: 0x003)
Minimum RX AMPDU time spacing: 16 usec (0x07)
HT RX MCS rate indexes supported: 0-7
HT TX MCS rate indexes are undefined
[...]

It should not if the parameter was really taken into account. Is it normal ? What am I missing ?

Best regards,

Anthony.

Hello,

We have the EVK-JODY-W163 ( CYW88359 and CYW89359) which support  Linux FMAC drivers. Do FMAC drivers support monitor mode?

Thanks in Advance,
