I have Verizon DSL service at 3.1 to 7 mbps. My house is 1 mile from a verizon switching station. Not an office but a small building housing Verizon equipment. when I test my speed I usually only get 2.4mbps download and .72 upload and that's on a good day. Right now it's running at 2.15. Shouldn't I at least be getting 3.1mbps?
