Wifi not working in my blackberry z10 stl-100
I have a z10, model number STL100-1, software release 10.2.1.2102. I noticed my wifi no longer works and all my saved wireless networks have been deleted. When I switch my wifi on, it doesn't detect any network around,doesn't even show it's scanning for any. when I try to add a network manually,it doesn't save it. I've pulled the battery, made sure mobile hotspot and Internet teetering were off, finally had to do a factory reset still the same. This is been going on close to 3weeks and all my other devices can at least find 5 networks around without connecting, my z10 can't even detect 1 network. it Detects network that was not shown in other devices.
I tried to reload my device and i successfully reloaded again same problem.
yesterday i got the latest software update 10.2.1.2941 and i installed again same problem
