My network is running through an Ecessa Powerlink 100 and a Sonicwall NSA 3500. I have two ISPs - an Adtran provided by TW Telecom (I think they are Level 3 now) and an Ubee provided by Time Warner Cable.
Recently it was decided our connection speeds were too slow so we upgraded both our Time Warner Cable and our Level 3 service. The Level 3 service is now 20 Mbps up/down and the TWC is 20 down and 2 up. After the changes were made I realized that my download speeds had not increased. When I run a Speedtest my upload speeds get an appropriate 18 Mbps but my download speeds never go above 6 Mbps. I have tried disconnecting each ISP connection to see if the results change but they don't.
My question is this: Is there a setting or something I should be looking at either on the Sonicwall or the Load Balancer that might be keeping the speeds at a certain cap? The fact that both ISPs separately still only provide me with a 6 Mbps top download speed makes me think there is something stopping it from coming in higher.
