Something wired keep happens every time i use Bitdefender internet security
it causes some problems with my wifi computers , after a while of using the notebooks it cut off the internet for a moments " and saying no internet access " and then come back
this problem doesn't solved , after i update my router firmware and restore it to factory settings and everything
the only solution was to remove bitdefender and replace it with another internet securty , and it's kinda sad cause i have like 100+ days left in bitdefender
