A couple of days ago, I logged on to a free wifi network offered by my local garage. The network requires no password and I logged on automatically and immediately. This morning I returned for some further work and was unable to log on. I could see the network, it moved to the "upper part" of the Settings > Wifi page and I got the spinning wheel - but it never connected. I had a full signal strength according the the "fan" symbol. I "forgot" the network and tried again, I "forgot" the network and restarted the iPad, I "forgot" the network and reset the iPad and none of those actions allowed me to connect, all I got was the continuously spinning wheel. Another customer logged on through his iPhone with no trouble as did an Android user. The garage staff conformed that, to the best of their knowledge, their network was working as normal. It's a little academic now as I shall not be back there for quite a time, but for future reference if this happens elsewhere why could I not log on and what troubleshooting steps should I have taken to correct whatever was wrong?
