WiFi dongle not connecting to Windows mobile hotspot

[dragon]

I use WiFi dongle with RTL8188 chip. I can connect my stereopi on router, phone hotspot but cannot connect to my Windows mobile hotspot. Maybe you know what the problem is?

Sorry, I have no Win mobile device to check this. Looks like you need to check regional settings on your Win mobile hot spot, and also security settings. As this dongle works with your router and phone hot spot, I think this dongle and current StereoPi settings are Ok.

WiFi issues are always hard to debug.
Since your setup works with other beacons, I would first check the channels: depending in the regions, different channels are allowed and your phone might emit in a channel that your dongle do not scan. For the troll, Windows is known to be insecure by default and you can check if it (do not) use the WPA protocol.

Code: Select all

iwlist wlan0 scan | grep 'ESSID\|WPA\|Channel'

On my StereoPi (currently OpenCV image, but I guess that this tool is on SLP as well), the result looks like this:

Code: Select all

pi@raspberrypi:~ $ iwlist wlan0 scan | grep 'ESSID\|WPA\|Channel'
                    ESSID:"Home network"
                    Frequency:2.412 GHz (Channel 1)
                    IE: WPA Version 1
                    IE: IEEE 802.11i/WPA2 Version 1
                    ESSID:"Repeater beacon"
                    Frequency:2.437 GHz (Channel 6)
                    IE: IEEE 802.11i/WPA2 Version 1

Here two networks are seen:
- "Home network" on channel 1 using WPA1 and WPA2
- "Repeater beacon" on channel 6 using WPA2

My PC sees a third one on channel 112 [5GHz band]
