i have had a problem with my internet for about four months now. i have now been trying to figure out why the internet drops for about 30 sec to a minute and then comes back up and within another minute its goes down again. i have called bellsouth and they have done what they can supposedly and we have replaced the modem and the router and cleaned all of the Computers. also whenever i am excessivly using the internet on my computer the modem restarts. then i thought that my computer was the cause and this is where i am at right now trying to figure out why my entire internet to the entire house to go down.
