I'm having constantly very, very, very slow download speed on my DSL. In some cases the upload speed exceeds the download numbers. The download varies between 0.4 and 1 Mbps while I'm paying for up to 7 Mbps. Once in a wild I'm having speeds around 4--6 Mbps but that happens once a week or so. And no, Verizon does not allow me as existing customer to swish to FiOS. Should I migrate?
