Για την περίπτωσή σου σκέφτομαι πιο πιθανό το hardware πρόβλημα. Και όταν λέω hardware, 2 πράγματα εμπλέκονται : το router σου και ο wireless adapter σου. Επειδή όμως το ποσοστό της ισχύς του σήματος πέφτει σε όλα τα διαθέσιμα δίκτυα και όχι μόνο στο δικό σου, πιθανολογώ για πρόβλημα στον adapter. Δοκίμασε με κάποια άλλη κάρτα δικτύου (πχ. USB ), αν έχεις και μπορείς να χρησιμοποιήσεις πριν καταλήξεις στο τι φταίει.
