Sorry if this is question is too silly. Newbie here. Hello, tl;rd I need to be able use the CM4 camera with my wireless router. Do you know any direct ways or have any drivers that work for you? I recenty started using the [OAK-D-CM4](https://shop.luxonis.com/collections/all-in-one-dev-kits/products/depthai-rpi-compute-module-4-edition) and I am in a remote enough place that I don't have access to an ethernet port. But I do get a wireless signal from a company router. I want to use my wireless dongle if the carrier board does not have WiFi modules, although I did see in the documentation that the CM4 Module has a Wireless module. But on the panel I see 'No wireless interfaces found'. (I tired a few simple tricks off of the internet but they don't seem to work.) **Are there any guides on how to ge the wireless set up going in my case? Are there any drives I can look into for the TPLink AC1300 WiFi dongle I already have?** EDIT: I realized that there is a Broadcom chip onboard. Should I maybe just reset the Camera and try again? If so, how do I reset the Camera= I see the button, but whats the procedure? Any update or direction would be much appreciated. Thanks in advance, Tarocal.

Hello @"tarocal"#p3375 , The RPi CM4 should have wireless connectivity. What's the serial number written on the CM4? As we can determine the model of the CM4 to be able to confirm whether it has wireless connectivity. Thanks, Erik

@"erik"#p3404 Hello, Next to the lens, under DEPTHAI, it has DM1097 R2M0E2. Just to confirm it once again, the RPi underneath has the BROADCOMS chip a well. Hope this helps, Tarocal.

Hello @"tarocal"#p3405 , We will debug it further in the start of the next week. Sorry about the inconvenience! Thanks, Erik

Can you please debug mine as well, I receive a message "No wireless interface found". DM1097 R2M0E2

Broadcom#2711ZPKFSB06C0T. I received the kit last week

Hello @"mohabsi"#p3418 , I have found that commenting out ``` # For OAK-CM4 to show uSD card #dtoverlay=sdhost,poll_once=off ``` Inside /boot/config.txt will fix this issue and you will be able to see WiFi interfaces. I am not sure what will be consequences (CM4 won't be able to use SD card? not sure), but I have yet to debug it. Thanks, Erik

It worked! Thanks much. I can live with this as a temporary fix.

Awesome, thanks for testing and confirming @"mohabsi"#p3438 !

Hi, @"erik"#p3436 I just received an OAK-D CM4 and have successfully connected via Ethernet, and it looks like #dtoverlay=sdhost,poll_once=off is already commented out in /boot/config.txt but I'm still getting "No wireless interface found" via sudo raspi-config. Do you have any other suggestions to try? Thanks

Hi @"kohani"#p6942 , Does the RPi CM4 have the WiFi module on it? I think the wireless module is marked with blue arrow, while eMMC is marked with red one. [URL=https://i.imgur.com/spTd5yL.jpg][IMG]https://i.imgur.com/spTd5yL.jpg[/IMG][/URL]

OAk-D-CM4 over Wifi (drivers)?

Thanks for this clarification
Got it, if it would have type C or this boot_USB it would have been nicer to work in production environment. Is PoE supported because I can see pins labelled with PoE hat CT1, CT2, SP2, SP1, if yes where can I get it?
I have not flashed new OS yet, will try and update here.

Hi AnshumanFauzdar ,

Looking at the schematics I believe it should, just note that the SOM heatsink will be in the way, so you might need extension header (like this), so you'll be able to connect the POE hat onto the OAK-D-CM4.

AnshumanFauzdar

erik Where can I get the PoE hat? Buy link will be appreciated. Thanks

erik

Hi AnshumanFauzdar ,
We don't have our own POE hats, but any from Amazon (for rpi 4) should work.

AnshumanFauzdar

erik Thanks!

erik I flashed with the newest RPi OS and still dongle is not detected, when doing lsusb, I am getting the list with the device in it:

Bus 001 Device 007: ID 0bda:b711 Realtek Semiconductor Corp. RTL8188GU 802.11n WLAN Adapter (After Modeswitch)

and I followed following post and I am getting on make step and errors are like this:

make ARCH=aarch64 CROSS_COMPILE= -C /lib/modules/6.1.21-v8+/build M=/home/cm4/Downloads/rtl8188gu modules

make[1]: *** /lib/modules/6.1.21-v8+/build: No such file or directory. Stop.

make: *** [Makefile:1895: modules] Error 2

Hi AnshumanFauzdar ,
Seems like drivers are needed, could you try following the tutorial here?

AnshumanFauzdar

erik Hey, forgot to attach the repo in previous reply I tried the same repo, I am getting error on make step:

erik

This doesn't look that straight forward.. We will grab the same wifi dongle and prepare a new RPI OS image that has drivers installed for this dongle.

AnshumanFauzdar

erik thanks for the support, please share the process here also it will be useful for future reference also.

AnshumanFauzdar

@erik Is there any update or you can arrange alternate WiFi dongle which works? I waited a long time for this!

erik

Hi @AnshumanFauzdar ,
We apologize for the delay, we have released an updated RPI OS image (v10) here, could you try following the flashing tutorial here ?

AnshumanFauzdar

erik I flashed twice, first time wifi was working but login was not working

Second time login is working but wifi is hit and miss.

By hit and miss I mean it shows connecting and sometimes connects:

Hi AnshumanFauzdar
https://stackoverflow.com/questions/76495004/installing-tenda-w311mi-usb-adabter-on-ubuntu-22-04

This was used to install the drivers. Perhaps consider re-running the commands.

Thanks,
Jaka
