Here is my situation. I previously had an old (5+ years) cable modem with my Comcast service. That is plugged into a Balance 310, and an AP One for WiFi. For the last year or so, I was able to get about 30Mbps down, and 6Mbps us, both on the router by ethernet or on the AP One wirelessly. Comcast has decided my modem is no longer acceptable and it is no longer supported.
They have since replaced my modem with a newer version. Since then, my Balance has been suffering. If i run a speed test directly at the modem, I can get my advertised speeds of 30/6. However through the Balance on ethernet or by WiFi, I’m sitting at a very painful 14/6. I have attempted changing the MTU size and auto, and regardless of setting it connects with the proper IP but I’m still stuck at this same slower speed. The Balance states its auto negotiated with the modem at 1000Mbps Full Duplex.
Here is the other thing throwing me. I can run a PepVPN speed test from the 310, and if I push UDP traffic I can force it to hit 30Mbps. I can’t quite lock down the issue where my normal web browsing on my wired or wireless clients is getting throttled so bad through the Balance. On 6.1.2 2717.
Has anybody else seen this issue, or is there a recommendation for a setting change?
