Can't connect to wifi & wpa_supplicant.conf dissapears

I got my complete mmdvm from ebay 2 years ago and never got around to trying to use it until now... So maybe its outdated and needs to be updated, I don't know... Anyway, what's happening is...

1. I created the "wpa_supplicant.conf" and copied it to the root dir on the SD card
2. Plug in the MMDVM and wait a few minuites.. I do get the colorful lights and screen saver on the OLED, but it doesn't want to connect to wi-fi
3. When I try to go to http://pi-star or http://pi-star/local after a a time-out it will either say host not found or go to pistar.com which obviously isn't the right place.
4. To rule out the problem with my wifi at home, I created a hotspot on my cell phone that I can connect to with a tablet, yet the MMDVM does not connect.
5. funny thing is that each time I unplug the MMDVM to take the SD card out and change the "wpa_supplicant.conf" file - the file isn't there on the SD card...

For some reason, the config file is some how deleted from the SD card every time it boots up and or I take it out to check or change the file... That is, when I remove the SD card to check or change the SD card, the file is gone.

If you have any help or suggestions that would be greatly appreciated. If I need to flash a new operating system or new files to the SD card, I'm not opposed to do that - please help - thanks

The wpa_supplicant.conf file is removed from the root directory when it is found at boot time.

You need to look at http://pi-star.local probably best to use Chrome.

thank you... I didn't know it's normal for the file to be deleted at boot, however, it doesn't connect to wifi- or cell phone hotspot. I have tried firefox and google chrome, but as I said, I am unable to connect to the MMDVM control (regardless of how I try to get there), because it is unable to make a wifi connection (to anywhere) for some reason.

(just for clarity - when I create a hot spot connection with my phone, I can see the number of connections when someone or something connects to it - i.e. my tablet to test it and my settings.... Yet the MMDVM does not connect to it)

That being said, I did check my settings and try it again based on your suggestion and still no wifi connection

>>>>>>>>>>>>>>>UPDATE>>>>>>>>>>>>>>>>>>>

Ok, after watching a different setup video on Youtube, I noticed that the guy in the video connected TO THE MMDVM with his computer wifi settings... For some reason I thought I was suppose to connect the MMDVM to my computer or wi-fi (not the other way around).

so anyway, not that my computer is connected to the MMDVM, I can now access the pi-star desktop and configuration pages...

HOWEVER, I see that the MMDVM still doesn't want to connect to my wifi - neither on the phone hot spot or the home wifi- what am I missing here>?

What ur describing above is the pistar setup AP if it boots with no connection config, or no Wi-Fi preconfigured network in sight it falls over into setup AP mode. You use it, by connecting ur computer to it and configure for ur Wi-Fi. Once setup the MMDVM device connects to ur Wi-Fi, then you connect to it through ur Wi-Fi, and no longer through the AP setup.
(Which as the name suggests, is for the initial setup of ur connection)

ok - thanks.. however, there is/was a config file put on the SD card to tell it what wi-fi to connect to... AND I do see that info on MMDVM pi-star configuration page but it says no link and it isn't connecting.

any other suggestions on how to get it to connect to my wifi ?

<<<UPDATE>>>

Ok, after much horsing around, I am now able to get the MMDVM to connect to the internet...
...so for anyone else having a similar problem, it seems the zoomspot does not like an SSID that contains spaces or one that is more than 8 characters.

You should be able to start from step 3 above - press Configure WiFi and add name and password for your wifi network manually.
I suggest you don't use Reset WiFi Adapter to scan for available wifi networks, because that will kill the Pi-Star-Setup wifi.

Currently the Wi-Fi all my hotspots are connecting with has a 10 digit SSID so I don't think that's correct.

Mine connect to SSID's that are well over 8 characters, some are even over 16 characters.

You could try and use the wifi builder to build the wpa_supplicant.conf file instead of doing it manually. Andy has used some tricks by converting the ASCII into HEX to get around goofy unicode characters that Apple uses, I'm sure using the wifi builder tool would get around the use of "space" in your SSID issue.
