Successfully Jailbroken iOS 9.3.3, but no sound and no Wi-Fi connection

I've successfully jailbroken iOS 9.3.3, but I have no sound whatsoever. Sure, the ringtone works, but alarms, timers and even notifications have no sound whatsoever, and Wi-Fi connectivity also doesn't work, sure it connects to the network but keeps giving me an error, I've tried another Wi-Fi network, and that didn't work too. Please help me ASAP

PS: I've tried to reset my "network settings" but that didn't work either.

Here's the list of modifications I use:

1) 20 Second Lockscreen
2) BerryC8
3) HotDog
4) Power Tab
5) Virtual Home
