I am trying to create an access point in compute module 3(and latest Raspbian OS) with the Edimax WiFi dongle. But it did not succeed to create.

Anyone please help me to do that in the latest Raspbian OS.

The latest Raspberry Pi 3B+ board has built-in WiFi. No one trying to use external WiFi dongle in latest Rpi 3 B+, So its difficult to get support to create an access point in the latest Raspbian OS. I think the other WiFi dongles are blocked in latest Raspbian OS

I am not much familiar in Linux OS and wifi drivers so anyone please help me to create an AccessPoint in the latest raspbian OS?

I am using the raspebian image once I configured for the WiFi hotspot using the Raspberry Pi 3 board. Now I am trying this same OS image with Editmax dongle and Raspbeery PI 2 borad

Update from the comment:
I am preparing the Rpi Image for the Compute module 3(I ordered it from the online store but not received yet). Currently, I have one Rpi 3B+, Rpi 2 B+ and Rpi B+ boards. I am creating a custom device using the Compute module for that I prepared a Rpi OS image using the Rpi 3 B+ and tested this Same image with the Rpi 2 B+ with WiFi dongle(Because Compute module not having a built-in WiFi module and ethernet module). In the same time, I am changing the ethernet configuration too. Not sure which configuration change made this work. Anyway, it is working now. I will try this image in the Compute module once it received from the store.

  • I think the other WiFi dongles are blocked in latest raspbian OS - huh? no, why would they? Just search for raspbian stretch ew-7811Un access point and you'll find all you haven't bothered looking for – Jaromanda X Feb 28 at 12:12

    Please plug in the WiFi dongle, edit your question and add the output of this command: ip addr. – Ingo Mar 1 at 10:00

  • The wlan0 has an ip address and wpa_supplicant is up and running, showing ESSID:"CPort_AccessPoint". So just connect to it. What's the problem? – Ingo Mar 4 at 13:24
  • I don't understand, How this worked? It's working now in my Raspberry Pi 2 board. 2 days before, I changed my experiment board from Raspberry Pi Model B+ to Raspberry Pi 2 board. My compute module still not come yet. Hope this Rpi image will work in Compurte module without any change. Thanks everyone – Arun Kumar K S Mar 5 at 7:36
