I have a 2 wire 2701hgb router. Recently the Internet, and dsl light go from green to red. After the lights flash red for a time it goes back to green. Today in addition to the above mentioned lights, the power light will also flash. I recently bought a new laptop. My old computer is still connected by wire. The issue seems worse when they are both on. However I have seen it do this when all computers are off. I also have an ipad and iphone that also access this router. Any ideas?
