Sonicwall TZ205w Bandwidth issue

[Bgarret]

I have a client who had 15x1 internet. Speedtest showed consistent 15 Megs.
Called and got and Upgrade to 35x3. Cable company had to come out and upgrade the modem.
Modem upgraded, Speedtest should be in the area of 35 megs. Only pulls 6 megs.
I hook direct to the modem and I get around 38 megs. Through the router only 6-7 Megs.

Any ideas.. I thought i should be atleast getting the 15 Megs from before.
I put a lower end router in place and It works fine..

Thanks in advance

Do you have any of the UTM services enabled? They will surely slow it down. Also try making another port the WAN and play with the link speed settings. I have had problems with Sonicwall and some cable modems. In addition, make sure you are running the latest firmware.
