Slow internet connection through NetGear switch

I have a bonded ADSL internet connection coming in to my network through a single 100MB port on a Netgear FS700TS switch.  If I plug the RJ45 lead from the bonder straight into my laptop, I get roughly 30Mbit connection to the Internet (which considering the location of the site is excellent) so I know that the Internet connection works.

When I connect the Internet connection into the port on the switch, the available connection speed drops off dramatically.  This happens even when there's nobody else using the Internet in the building.  Any PC on the LAN will get an Internet speed test result of about 1985kbps when nobody is accessing the net simultaneously.

Funnily enough, our previous single-line ADSL Max connection with Zen Internet used to give roughly the same speed test results on the LAN in similar circumstances.  I feel that there is a network issue here and was wondering if there are any suggestions as to how I might diagnose the problem.

The Internet connection comes into port 48 on the Netgear Smart Switch.  The port is listed as running at 100MB in MDIX mode in the configuration manager for the router.

DHCP and DNS for the network is handled by a Windows 2003 Server.  The Netgear switch gets its IP address and so on from this DHCP server.

If I can get 30Mbit connections from the Internet without the switch in the loop, why can't I get the same speed when the switch is active but no other users are using Internet bandwidth?  Is there a setting in the switch manager that needs to change in order to fix this?

Any help much appreciated.

You mention a speed of 100Mbps. What is the Duplex?  

You should check both ends of each link.  ADSL <-> Switch <-> PC.    At 100Mbps, both ends of a link need to be set the same.  Either Auto/Auto or 100/Full for speed/duplex.  If they are not the same the end that is set to Auto will come up Half duplex which will cause a degradation in performance depending on the direction of the traffic.

Cheers,
Gary

In the world of WAN, QoS is a pretty important topic for most, if not all, networks. Some WAN technologies have QoS mechanisms built in, but others, such as some L2 WAN's, don't have QoS control in the provider cloud.
Data center, now-a-days, is referred as the home of all the advanced technologies. In-fact, most of the businesses are now establishing their entire organizational structure around the IT capabilities.
