Sonicwall TZ-105 Wan Throughput limited to 35Mbps on 100/10 connection
2 Lan VLans. 2 wan connections are configured in failover mode (not round robin etc.) I also tried disabling load balancing - no change. If I connect at the modem (ubee cable modem in bridge mode) I am getting the full 100mbps. The TZ-105 with no security services active and dpi disabled can not break 35 and is often lower. This is not the wireless model. No subscriptions are active on the unit.
The primary WAN interface auto negotiated to 100 full duplex. MTU is 1500 on the SonicWall. I have the same device in a different office with a 60mbps Fiber connection (same config except no failover WAN) and I get the full 60 with DPI enabled. I upgraded to the latest firmware.
I also contacted their horrible support and paid for a year of support on their site. After doing that they wanted me to pay for another year as the original support had lapsed a year ago. In other words they wanted the back support money.
Any ideas on fixing this?
Not seeing many better units out there. Not crazy about the Cisco RV320 (some bad reviews out there knocking the firmware) but the throughput is better and it is just a bit more than the Dell "warranty" fee.

The TZ 105 is supposed to provide 200mbps so technically it should be capable enough. It would be great if there were some fix for this but I have tried many different settings with no change.
Perhaps it is something between the ubee modem and the firewall as the same device is performing correctly at other locations. Using the same cable I get the full 100mbps on my laptop.
Thanks for the input on the RV325. Good to know it works well for you.

Will certainly steer clear of that model in the future. What bugs me is the same device, configured the same is routing 3 times the traffic at double the speed at another office.
@YMartin - Thanks for the update and I was happy to help.
The RV325 works fine, newest firmware, not buggy, several permanent site to site tunnels that are always up.
You do not need to use Cisco if you do not wish to, but get a faster router to give you better speed. That is what I did and it worked.
