No internet connection

Do you have an Internet service provider (ISP), like AT&T or Verizon (if you live in the US) ? Usually, your ISP will give you a modem/router (cable or DSL) for free when you sign up with them for Internet service.

whenever the connection drops, is the DSL light blinking?
because, it is just normal for the E1 light to blink, but the DSL light should be solid at all times.

It can be a possible issue with the cable or the LAN card, but you still need to have your line checked by Verizon to make sure that it is not a modem or a network issue.

make sure that your old setup not still on go to connect to from the start and right click on the connection and see the one that you are using is present

verizon dsl westell 7500 internet light goes off 2 to 3 times daily

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.

to answer your first question, call verizon to fix the line. it is dropping. Second have verizon change a dsl and test it out.
as far as the tab on the CAT-5, the tab is to lock the cable in place, without it, it will work but you have no insurace as to the connection status. (need cable with tab).

Contact verizon if they can replace the router becase the internet light should be green and flashing as you use the internet.

you have the DSL filters plugged into all your telephones, but NOT plugged into the DSL modem?

is the DSL modem configured to automatically connect using your username and password?

have you tried using a different phone cable, or plugging into a different phone jack?

Its your network problem! your network doesnt support more load at DSL lines! you must complaint to them about this! Its not hardware malfunctioning its all about network issues!

Ok right I love these issues. Here we go!! First I want you to determine if this is a no sync issue or if this is a no route issue. Know this is the difference between working with Verizon or working with Verizon On-Line. If you have a sync issue which means the DSL light is off or blinking, this would be a Verizon proper issue and is easy to have fixed, however if the DSL light is on and the internet light is off this means that you have not received a PPPoE derived address and thus while you have DSL (Digital Subcriber Line) sync you do not have connectivity to a gateway router to route you to the Internet. I want you to log into you DSL modem (http://192.168.1.1) then using your login ID and Password the one you configured for the Router not Internet access. And the go to the screen that show your DSL connectivity see if it is up or down *Remember DSL refers to the layer 1 connectivity, and PPPOE refers to the layer 2 connectivity". If the DSL light is on this meaans that you have to call verizon and say "My DSL light is on, but I am not getting an IP address which means my layer 1 connectivity is working, but my layer 2 PPPOE connectivity did not provide the platform for my layer 3 level to be built". so this now becomes a task of troubleshooting the layer 2 systems (PPPOE server, and IP Address delivery systems, and Redback SMS). Instead of a half hour of "is your modem plugged in". If your DSL light is off then your layer 1 systems are not working this could be anything from your modem to the ASAM ( ATM Subscriber Access Multiplexer ) system or DSLAM (Digital subscriber Line Access Multiplexer). In any case if the DSL light is off they just have to figure out why. This can be done at the central office by disconnceting your cable and pair and trying to sync up at the vertical shelf (Ca/Pr) or at the split bank. If they sync up the problem is outside, if they do not sync up the problem is inside the CO either at the Split bank or the DSL OE block. If the problem is in the CO they will fine and fix it. If the problem is outside, what you can do to expedite things is to take your DSL modem to the NID (Network Interface device) and connect to the phone line that has DSL on it and try to sync up there. If you can sync up the problem is inside of your house, if you can not sync up the problem is outside of your house prior to the NID and thus is verizon's responsibility. I hope this helps.
