I have DSL/verizon,modem 6100F i keep loosing my internet connection

Your problem definitely sounds like an intermittent connection problem. It can either be one of two things. #1. You have a defective modem, or #2 It's a network problem. I will definitely go with #2. Here's the thing. The problem you have is very very very common not only to Verizon DSL customers, but also to other Internet Service Providers as well. The best way to fix the problem is to understand what's causing the problem. There are two types of intermittent connection problems. The first is Intermittent Sync. You'll know if you have this problem because the DSL light will be blinking everytime you get kicked out. That means there's no internet connection, The modem cannot detect and establish a connection with the Central Office. The second is Intermittent route (which I know is you're problem), The DSL light is steady, but the Internet light almost always turns OFF or turns RED. The only way to fix this problem is to coordinate with Verizon. The reason is because the problem is outside your house. The long cable lines, the drop wire, the cables that passes through from the Central Office to your House can all be damaged, If that's the case, then a technician is required to go out and fix the problem. Don't worry about calling Verizon, this is a network problem and you won't be charge for anything. I know losing internet connection is very frustrating. Give your ISP a chance, they will definitely fix the problem if you give them the opportunity to do so.

If Verizon cuts off non-basic service because of billing issues you would have no Internet access at all, not intermittent access. So this has nothing to do with you. You might have telephone line problems that are interfering with your DSL service. Is this something that started after storms? Could be wet lines or loose connections outside. I've had to go several rounds with tech support before they finally sent a technician out and found line problems on their poles. Are all of the telephone jacks other than the DSL connection properly filtered? You might also have a bad modem. I've had to replace six of those 6100F modems for people over the last year. Fortunately they were all under warranty from Verizon.
