I have a network connection issue and I don't really know how to go about fixing it. The issue is we have a remote site that is in a customer building. In the building we have a storeroom which we store products for the customer when they need them. I have a workstation in the storeroom that is connected to an internet connection which creates a SonicWall Site to Site VPN tunnel. The Internet connection is a 1.5mb DSL line which has the workstation and a vending machine attached to it.

The problem I am having is that the workstation has really bad network connectivity and loses connection to the SonicWall router often and is really slow. I have other clients that are on a 1.5mb connection but it is a T1 line instead of a DSL line and there are 4 people who connect to our network the same way but do not have the same problem probably because they are on a T1 line.

The client connection that is having issues is connected to the SonicWall via an ethernet cable which is 406 feet long and has POE switches on each end. I told the customer that they cable was too long so their solution to boosting the cable signal was to place the POE switches on both ends to boost the signal but I don't think that will work. The SonicWall has GB ports on it which is connected the GB port on the POE switch but when the signal reaches the end POE switch the signal is degraded to 10mb instead of 1GB. I am to assume that is due to cable length but I have some clients in the building that have a similar length maybe, not as long but they don't experience this type of drop off. Additionally the client at the remote site has slow logon time and their connection to the SonicWall drops often. Again I assume it is the cable length but I want to make sure.

I want to bring in a new line that is high speed but if this is a line issue and not a bandwidth issue a new internet connection will not help since it is a line issue instead of a bandwidth issue.

How can I test/resolve this issue in order to fix this issue?
