Hello we are running a Sonicwall Pro 2040 with the 188.8.131.52-12 enhanced firmware. We recently upgraded to cable modem internet service from a 1.5 T1. If I hook a laptop with a static ip directly to the cable modem, I'm getting about 30 mps down and about 8 mbps up. Inside my firewall I'm getting about 8 mbps up and 8 mbps down no matter which machine I run speedtest.net.
I have experimented with disabling the VPN tunnels, content filtering, AV, and IPS on the Sonicwall and that doesn't seem to make a difference. Also disconnected the servers from the network and that didn't help. The connections monitor on the SonicWall didn't seem to look very remarkable either. The only think I've noticed to make a difference is when I reboot the Sonicwall, for about the first two minutes after it reboots, I'm getting 22 to 25 mbps down and 8 up. Shortly thereafter, its back to the 8/8 speed. Any ideads ? Thanks!
