Hello,

Hi Which encryption are you using for those Apple clients?

This is because Apple doesn't recommend to use old encryption methods such as WPA1 (TKIP)+PSK or WEP.

The problem only occurs with those productcs?

I have to mention that 5.1.151.0 is a very old code, you migh start considering moving to the latest code 7.0.240

Here are the release notes so you can take a look:

Here is a link from apply about the recommendations for wireless networks:

Avoid running the 5.X firmware at all cost.  It's has been awarded the "buggiest" wireless firmware as to date.
