can not connect to wifi

Submitted by bobdylan on Sat, 07/03/2015 - 08:46

hello

I have got my monitor working , and its updating to emoncms. (but only when it is connected to an Ethernet cable). so following some of the post i have decided to try a wifi dongle approach,

I have purchesed a "EDIMAX nano adaptor 802.11b"

but when i follow the set up guide

http://svay.com/blog/setting-up-a-wifi-connection-on-the-raspberrypi/

and try to add the device in step two

/etc/wpa_supplicant/wpa_supplicant.conf.

i get a "No Such File " error on my pie..

is there any issues with the "emonSD-13-08-14.img" i have running

or can somebody help me get around this problem

thanks in advance

dylan

Check for typos... it should be there!

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

If not then just create a new file.

The rest of the steps in that guide are good, I had to do the "ping your router every minute" to get mine to stay connected to some routers. With my home router (Verizon FIOS) I don't need it, but other places I have needed it and I see several reconnects per day in the logs.

I've always added the wifi credentials directly to interfaces file rather then a sperate wpa file. I recommend following this guide, I've tested with latest emonSD
