Our business has 2 dsl lines. The first line is used for a wired network of computers and the second line is used for a security dvr and wireless router. This morning both modems showed no internet then the 1st line withe the wired network came alive then died the came back. The second line still shows no internet. The dsl service has been shutting a program that collects stock quotes on a continuous basis for the past month if this could help in solving this problem.
