Hi, I noticed this happen recently..my wifi connection at home suddenly disappears and reappears after a few minutes..usually I just unplug and replug the power of my wireless router.. is this common for old routers? Im not sure if its the router..as i have to a-b it versus using direct cable..I noticed this a few months ago at my old apartment..but now in my new one with a new connection its been happening quite often..should I buy a new wireless router? I dont think its my internet connection thats cutting out..your thoughts?
