Unread postby MonC » Sat Nov 25, 2017 9:19 pm

Hi guys,

I have a problem with connecting the device to my wifi. The connection times out and network manager asks for password. I was trying to find the problem and I enabled tethering on my phone and odroid managed to connect to the hotspot..

Hardware/software setup is:

- odroid c2
- wifi module 5
- ubuntu mate 16.04
- tp-link eap 110
- huwei openreach hg612

Wifi network setup:

- WPA2-PSK
- AES
- 802.11b/g/n mixed
- 20/40MHz
- 20 tx power

We had no issue with a few different 2.4Gz and 5Ghz APs when we tested WiFi module 5 a couple of weeks ago.

Can you try “iwlist wlan0 scan” on the command line?
Also try to change the channel of tp-link setup not to use ch#12/#13.
