Question : SLow traffic through the Sonicwall TZ 170

For the past couple of years, we have been with Time Warner Telecom here at our office on what they call a "versipak" bundle.

We had 2 T1's going into a piece of TWT's equipment, then from there, their equipment would merge those T1's and split the available bandwidth to the data side based on the number of active phone lines we had going.

So basically, we had 3Mbps of internet, but as people picked up phone lines / made calls, the TWT versipak would take channels away from the data side and convert those to voice.

Anyway, we have just switched to a new package now. We now have a dedicated T1 for voice, and 4Mbps of bandwidth on a 10Mbps fiber port from TWT. The 10Mbps ethernet plugs straight into our WAN port on the sonicwall. The problem is that after we switched to this new offering, the internet is rather slow for us now. We're barely able to get above 1Mbps.

If I plug a laptop straight into the ethernet cable from TWT and configure the network port on it for the service, I can get the full 4Mbps up/down, but once I plug it back into the sonicwall, it slows down again.

I've set the sonicwall to Force 10Mbps Full Duplex, but still see speed issues.

The sonicwall is a TZ170 model, and currently has 7 VPN tunnels from other remote offices.

These remote offices have VOIP phones that tie back to our phones here, however, at the most, there are only 3-4 active VOIP connections at the same time. In addition to that, we have approximately, 4-5 active Remote desktop sessions to a terminal server back here as well.

Our pvevious connection was able to handle this fine, and we could still get 1-2.2Mbps on the data side.

CPU monitor on the sonicwall barely goes above 30%...I'm not sure why we're having issues with the speed now if anyone might have any insight, it would be appreciated.

Only thing I've been able to come up with, is trying a new router, but I'd rather not spend the money on it if I don't have to.

If I need to clarify anything, let me know.

Thanks.

I would think it would also, but I cannot say for sure. Perhaps someone else will chime in, but at this point their support might be able to give you the most direct answer.
