Did you follow one of the missing wifi SSID update processes, or did you just update directly from the web interface system page?
I flash the image onto the raspberry pi SD card. The version is .0.0.27.
Are you sure your raspberry pi is within range of the wifi router (e.g. do you have a strong signal to that network on a mobile phone or laptop where your ROV is)?
Can you use the terminal over browser and post the results of running:
sudo iwlist wlan0 scan | grep -E 'Address|Quality|ESSID'
If possible run it a few times as the results can be different.
If you are still having an issue the software team may need to organise a call with you, because flashing should definitely avoid the bug that we found with the update process, so this will be a separate issue.
I connect the computer and the pi with a network cable. I am sure my PC is connect to wifi.And the signal is good，because we can communicate by email.
The version is ok,the connect is ok,the signal is ok. I use putty to log in to Raspberry Pi，and run the code.This is result.
Besides，I checked a lot of information about connecting to wifi .When i run some code ,all the code that have wlan0 can’t run. It shows that the pi don’t have such device. But pi 3B support wireless network.Maybe the wifi module is broken or there is no driver？
Another way is to share the network to the pi through the pc. I try it,after i turn on wifi sharing，pi still can’t go onmine，because it caan’t run the code sudo apt-get update.
Can you try running
sudo screen -ls and seeing if the
network-service screen session is there? If so, please run
sudo screen -r network-service and post what’s in it.
You can press
d to detach from the screen session once you’ve got the info from it.
network-service is not there, please run
sudo -H -u root ~/companion/services/network/main.py
and post the error message that occurs.
Seems like your wifi is disabled/not recognised. This stackexchange post suggests
- use the up/down arrow keys to select
Localisation Options(press Enter once highlighted)
Change Wifi Country, and set the country you’re operating in
- Press the Right arrow key to highlight
<Finish>, and press Enter
- Enter again to reboot
- Hopefully wifi works now
If that doesn’t work then hopefully our software team has some idea - otherwise you’ll likely need to try a different Raspberry Pi.
It may be worth running
dmesg | grep WiFi to see if there are any startup messages related to Wifi being disabled or similar.
