Ever since we've started our verizon FiOs service there have been random times throughout the day where the internet will temporarily shut out for 5-10 minute intervals and then come back. It can be worse and these intervals sometimes last up to an hour.
When this happens, i am not disconnected from the actual internet itself but the speeds become so slow that they are at a standstill. (I don't have to manually connect to my wifi from my computer again after these connectivity issues and the speed comes back.) When i say random, i truly mean that this happens at random points throughout the day and there isn't really a pattern to when these issues arise aside from the fact that it seems to happen more often at night.
I've called verizon and they've sent a replacement ActionTec router but the problem persists.
I also notice that during these issues, i'll have more Received bytes than Sent bytes. (Sometimes 10x more)
