2.5 ghz password not what Nighthawk admin shows

Flash7Gordon, I think the iOS doesn't work the way you think it should? In order to use FORGET the network you MUST be in range of that network. Here is the rub, as far as I know ONLY the SSID and P/W is retained. That is all that is needed to connect. The MAC address is not needed. Some large places have repeaters that use the same SSID and P/W. If it saved the MAC Address it wouldn't connect.

So you were NEVER forgetting the network because you couldn't connect to it. When you FORGET it it just will not AUTOCONNECT to it. That network SSID now goes into the list you can select from.

Again, from what I know, and I could be wrong, this is what is happening.

First 'forget' doesn't delete the data, it just tells iOS not to connect to it. Data is still retained. So in your case it stops trying and then still appears in the list with the wrong P/W. You select it again and it does what it did before, tries to connect. You are in a vicious circle. About all you can do is RESET the network which does wipe all Wifi and SSID data out. However, with one SSID with 2 different P/W's you still have problems again.
