I recently returned from the beach and our modem and router has started strangely behaving. Ever 25 minutes or so the DSL light on the modem begins blinking and the one router light turns orange for a brief say 10-20 secs. then begins working again. This is all while it says we are still connected on the laptop yet it says no internet access. This problem occurs once then again in another 5 min. then it waits around 25 min. And repeats the process. Does anyone have any idea what the issue may be?
