I recently upgraded my Verizon DSL from 1.5Mbps to 3Mbps and I see a difference between the speed on the MODEM home page and the results of various speed tests. On the modem connection page the speed is LISTED as 2.464 and the speed test I ran on speakeasy.net show 2.059. Sometimes the speed is less than that. I am using a Westell 2200 modem and my desktop is running XP and my laptop is running Vista. I am using a Netgear WGR614 wireless router for the laptop but the desktop is cabled. The speed is about the same on both.
Is there a logical explanation for this difference? Are there any settings that I should change?
Any help would be greatly appreciated! 
Thanks.There are two things I can think of right now.    There could be QoS turned on on the moder or router by default which may reserve badwidth and that could limit your speed. It could also be the router interfering.   Try connecting a computer straight to the modem and running a speed test.    Know that you will never get the full speedI get the same results when I connect the desktop directly to the modem; there is always a difference between what the modem page and the speed tests show.
How do I find out if there is a QoS issue with the modem?
Thanks.........There's a difference for me too 

Check out the router config page and modem config page (where you check that speed) and look in the advanced sections. You can also find an online manual for your router and how to configure QoS.

Most routers and modems have QoS built in; different models have it on or off by default. I'm on Qwest and have the M1000 modem and with the previous version of the firmware QoS was enabled by default but it wasn't set up for any ports (it was reserving bandwidth but that bandwidth was never used). In their new firmware they have QoS off by default and I have NOTICED a speed increase. Now my router does automatic QoS for gaming and video.I checked the router settings menu and there is no QoS feature listed as indicated on the Netgear website for other models. I guess my model is too "old", and I didn't see any firmware upgrade that added this feature.
However I made some other changes which improved the speed. I disconnected a phone which was using the same jack as the modem and I replaced the cable from the modem to the jack with a better one. Now I get 2880 on the modem itself and about 2.4/2.5 on the pc's. I am going to continue my research on WHETHER I can improve on that but for the time being I happy with the improvement.
Thanks for the help.
 Have you thought of moving the DSL modem closer to the POINT where the phone line comes into the house? It may give better results with the modem and the filter set as close as possible to the place where the line comes into the building.Thanks. Its not very practical to do that because the line comes into the basement and my desktop is cabled to the router but I'll see if I can make the change.
