I wasn’t getting the upload speeds I was expecting. Not by a long shot. After troubleshooting the dsl line and the modem itself, the Speakeasy rep and I determined the Linksys WRT54G router was the issue. Upgrading the firmware to v4.21.1 didn’t improve anything. Then, after poking around the router’s admin settings, I found the culprit: Quality of Service (QoS) on Upstream Bandwidth was enabled. Disabling it gave me 2.5x the uploading speeds.
