Wifi hotspot using Dexter sd image


I have been trying to create a wifi hotspot on my robot so that when I take it into school I do not have to use the schools wifi or go Via my phone.

I have come across several sets of instructions over the last 12 months and never got any of them to work using my wheezey image.

This week I came across a post on cymplecy.wordpress.com with a script to set it up.

I ran this script on my Dexter image Sd card nas it did not work, lots of errors and I lost Internet access. Luckily I had backed up my image beforehand.

I then tried the script on a straightforward raspberry noobs image, I.e. No mods for BrickPI and it worked.

So my question is before I go and spend several hours investigating, has anyone created a hotspot?
