I have seen many comments about WiFi networks and the seemingly impossibility of the iPod to connect to some.
However, I have not come across a solution to my issue - there may have been one but I confess I've not been successful at finding it!
I have set up a home network. At first I used an Airport Extreme but then it died so I set things up with a NetGear DG834GT. The home network uses a WPA2 password.
At home no problem - my MacBook Pro (Core2Duo), my son's iMac i7, my 2nd Gen iPod Touch (4.2.1) and my iPad 2 all connect great to the WiFi network. I can surf the web etc etc. I'm a happy bunny.
When I'm out and about I often use my iPod Touch to get access to the web and my e-mails etc using WiFi. Most networks are secured meaning you have to type in a password. Hotels are like this and usually there is no problem once the front desk gives me the password. The unsecured ones are often WiFi Zone Hotspots where you have to pay to continue. I don't usually bother with these.
Some sites though offer unsecured, free access and free internet use - coffee shops in particular. A coffee shop near me has such a network and I have absolutely no problem connecting. However, I have come across a few networks which show up in the "Available Networks" list complete with name etc. And yet when you select this network and try to join I get the message "Unable to join such and such Network. Obvioulsy with no network connection there is no internet etc.
Usually I simply ignore this problem and wait until the next WiFi network is available (when I get home?). Not quite so reliable if home is 3000 miles away!
But does anyone know why there are some networks that I cannot join? Is there a solution for this that I can carry out? I've tried the usual things like resetting the iPod, forgetting the network etc. Obviously I do not have access to the router as this is owned and operated by the company/enterprise concerned.
Not a show stopper by any means but an irritation nevertheless. Incidentally, there were also a few networks recently on my travels where both the Touch and the iPad behaved the same. i.e. I couldn't join some networks with either device.
