Thanks for the help Allan, I went with the latter and downloaded the image, works perfectly, also thanks for the info on the status tests, I'm certain they will come in handy in the near future knowing my propensity for mucking up

Hi there,

Sorry for the delayed reply, can you please send the output of running

ifconfig wlan0

Also it would be a good idea to check the status of hostapd and the dhcp service with

sudo service hostapd status
sudo service isc-dhcp-server status

If you have a spare SD card then you can also download the complete image from http://downloads.dawnrobotics.co.uk/sd_card_images/ although this is less of a Linux 'learning' experience, which always seem to involve a fair amount of hair pulling.

Regards

Alan

Wifi not initializing

2015-04-19T07:13:35+01:00

Hi Allan, I've hit a snag, after corrupting the SD card that came with the kid I decided to create my own from the Raspbian distro https://www.raspberrypi.org/downloads/

Then followed the instructions in this link http://www.dawnrobotics.co.uk/creating- ... s-sd-card/ to add wifi and robotics control.

Everything works but the wifi, I'm able to control the robot and get camera via hardwired ethernet, the wifi dongle is the one that came with the kit, Edimax, the dongle uniformly blinks several times, pauses, then repeats this over and over, the robot does not show up on any of my wireless devices.

Please keep in mind I'm having to edit via Putty and SSH since I don't have a monitor to spare for the raspberry pi yet.

I hope you can help because I'm beginning to pull my hair out trying to find a solution
