Help Phone can't connect to WiFi

[Simpuff]

Yesterday i bought a Samsung Galaxy Gio. I had trouble trying to connect over WiFi, but after a while my phone randomly detected my connection. Now it won't connect anymore. I tried to reboot my router and my phone, but it didn't work. What can I do? (sorry for bad english, I speak french)

• open your keypad and type in *#*#526#*#*

Eumh... I pressed this code as well to see what it did... Problem now is that I no longer can connect to WiFi...

What did this code do to my phone? And how can I set everything back to normal lol...?

Worked great for me. It reinstalls the network driver. Solved all my wifi errors.

Well the phone says it has connection with my router, however, when I open the browser no pages can be found...

I suggest you unplug your router and reboot it.

Perhaps reboot your phone as well.
