We have a draytek router installed in one of our remote offices. It is Draytek 2820n and we have a few iOS device users. iPhone 4 for sure and an iPad that I know the users have.
The problem: neither of iPhone 4 or the iPad will connect to wifi. The error message is generic.. "unable to join <SSID>".
I have no idea why this is happening. I am not entering the key incorrectly. I have tried WPA2/PSK and WEP for security. Doesn't matter if it is WEP or WPA2/PSK. Doesn't matter if the key is simple or complex with characters like the @ sign.
There are 2 different iPhone 4 and both of them are showing the exact same behaviour. And yes, one of the user has a jailborken iPhone and would you believe even that is same.
Also the iPad is behaving exactly the same.
I have noticed this issue before as well. The iPhone 4 I have didn't connect to a few WLANs I have come across till now with same generic message. So I am saying that it is not just Draytek 2820n but my issues have been with various different networks.
If someone can help me out, that will be great as I am getting more and more of these complains.
And before you ask, these wifi networks are perfectly fine and NOT a single laptop has ever had issues with them.
