I don't own a time capsule ;( anyway is there really no other way to revert back to 7.1.2? Cos the wifi issue is really killing me. Even if I bring down to service center can they even do anything?
Btw, say if I upgrade my router to an airport. Doyle
Think it'll solve the wifi issue?
Airport uses the same technology as time capsule so I am sure it will work for me. But I have no idea whether it will work for you. Simply adjusting the settings on my zhone router helped... as advised by the apple care consultant.
The 2 settings are changing it to wpa2 and 20mhz for me. You might want to also try a channel which is less congested. Time capsule is great because most in my area (which I can detect) uses 2.4ghz and I am now using 5ghz.
If yours is still under warranty, give apple care a call. They were very professional about it.
