I had the same issue happen frequently as well.
For some reason the router decides to disable the radio signals and the only way to access internet or the router itself is through Ethernet cable.
The method that fixed it for me is the following:
- Connect to your MuDiV2 router via SSH;
You would do this by going to your computer terminal, type the following:
ssh root@192.168.8.1
then, enter your admin router password.
Once you are in:
check if the Wi-Fi radio is enabled by typing these two commands:
uci show wireless.radio0.disabled
uci show wireless.radio1.disabled
If either of these returns '1', the radio is disabled.
e.g.
wireless.radio0.disabled='1'
in that case...to enable the WIFI radios, input these three commands:
uci set wireless.radio0.disabled=0
uci set wireless.radio1.disabled=0
uci commit wireless
then, input these four commands to ensure the SSIDs are set and not hidden:
uci show wireless.default_radio0.ssid
uci show wireless.default_radio1.ssid
uci show wireless.default_radio0.hidden
uci show wireless.default_radio1.hidden
The 'hidden' values should be '0' for visible networks.
if it isn't, input this:
uci set wireless.default_radio0.ssid='YourSSID_2.4GHz'
uci set wireless.default_radio1.ssid='YourSSID_5GHz'
uci set wireless.default_radio0.hidden=0
uci set wireless.default_radio1.hidden=0
uci commit wireless
that will set your SSID name and will make them visible.
LASTLY and most importantly, reset the network with this command:
/etc/init.d/network restart
I hope that worked! Enjoy your working router. Leave a comment if it worked.
