Help have origional eamon pi I installed a new router today and my pi can no longer access the wifi so i presume it needs the password updating for the router. Please can anyone tell my how to do this. i have not realy had any problems since I installed it 7or8 years ago and it took me a couple of months to get it running proprlyn at install and have had no real problems since then then.Build emonSD- 30oct18. would be really grateful for any help

By far the best way (in my opinion) is to change the SSID and password of your new router to be the same as the old. This way, you don’t have to change SSID & password in everything that uses your Wi-Fi LAN, emonPi included.

If you can’t do this, or you’ve already changed everything else, I think you have two options:

  1. Connect to your router via Ethernet and use Setup → Network and choose your network, then type in the password, or
  2. Take the SD card out and edit the wpa_supplicant file - see Setup WiFi on a Pi Manually using wpa_supplicant.conf - Raspberry Pi Spy

(If you need to move the emonPi, remember to go through the shutdown routine using the button on the front.)

Thank you for your reply I was able to connect by ethernet and log straight in to change my password but next time I will take your advice and keep the router name and password the same.
