I am working at a building with DSL. It has a linksys g wireless router then a dlink 32port switch. It has 20 computers/printers running on network. In the morning, the network runs fine. After noon time, the DSL starts dropping until about 5-6 in the evening. It happens sporatically, not every single day, but most. I called at&t to makw sure filters on every line except thw line going to the modem. I checked, 3 filtsrs were needed and added. Would that be the issue, or it seems that something that runs in the sfternoon would cause this. Any ideas?
