My iPad 2 Air keep loosing the WIFI connection

Hi there,

As the title clearly says my iPad Air 2 keeps loosing the wifi connection, which before always worked fine, any other devices in the house works perfectly, laptops, phones and my girlfriend's iPad too (which is a different and older model), but my iPad keeps loosing the connection, it comes and goes constantly, I tried many times to hard reset it, I tried to do a network reset and to reset all settings too, but it keeps loosing connection, and I dunno anymore what to do... 😢

Please help...
