Thanks to all of your advice...just this morning, i reset the router config settings and changed the password. I've also already pinpointed who is the most probable culprit behind the attack...it was one of my customers who decided to play a joke on us. Either way, we're not taking any chances, the person is now under tight watch the moment he steps inside here. We dont want t take the chances of it happening again. Anyway, thanks for your advice everyone! To be honest, i was quite surprised, since im a newbie here, i didnt really expect that quick a reply. You can imagine my surprise when i saw such lengthy replies to my post... Thanks again!
