Help Problem with Wi-fi on Samsung galaxy S2 european version

[supermichael1]

Sometime when I use wi-fi it works but sometime I use wifi it doesn't work, it only say "Saved, secured with WPA2" and nothing else.

This happens everywhere in my house any wi-fi connection, how can I fix this?

I tried clearing internet cache data and clear data but nothing.

It say Samsung galaxy S2 GT-I9100 the one I have.

Bump

I typed on phone *#*#526#*#* I tried but then it connects and then something it doesn't connect.

I did today the number on top and when I did RX test it says 2.4GHZ no error, when I tried 5.2GHZ I think it says over 100 error.

I changed my wi-fi frequency from auto to 2.4GHZ I think and it works now, but I don't know if the problem will come back or not.

But the question is is this normal for my phone?

The SGS2 does support 5.2Ghz Wi-Fi, but not all channels. Setting your Wi-Fi to 2.4Ghz will, and obviously has cured the issue. Your SGS2 is acting perfectly normally, I don't think you'll have any more problems with Wi-Fi.
