Thank you for that link, will go take a look at it in a bit.
UPDATE:
Ok, so it was working....i powered it down before i left work last night. Just got in to work quite pleased with myself that it was working last night and that i was going to set up the second MR20 this morning.
So, I powered up the MR20 that i set up yesterday, saw a green light on device, checked my phone for a WAP and boom...instead of showing me the SSID i set up yesterday, there is just an SSID named Meraki and it wont let me connect to it...so i went into the web dashboard and the damn MR20 has a red button next to it in 'Radio Settings'...I just cannot understand why it's not working as all i did was power it down last night...I didn't change any settings whatsoever.
This is getting kind of frustrating now.
UPDATE2:
Soon as i posted this i checked the dashboard again and the light was green. I was able to connect to it using my phone but after an hour it went back to red and can't connect to it again now!
I've emailed Technical Support as haven't a clue why it is doing this.
