My internet speed has been reduced to 1mb from 3 mb since installing this motherboard. My router shows 3.5mb speed and my connection is 100mb duplex. Everything appears OK but the speed will not go above 1mb. Using my other computer brings the speed up to 3mb.

Greatings !
I put WORKGROUP within the domain name field of the Network tab.
Speedtest moved from 10Mb to 100Mb that is the maximum speed provided by my cableBox (Numericable).
Very good

Thanks a lot to Kasper Mikkelsen

This should explain it...http://www.helpwithpcs.com/internet/internet-connections.htm

Contact your local Internet Subscription Provider.

As of me, there is nothing can be named , THE BEST , but i have been using http://www.ip-details.com/ for the past 3 months to check my system speed, it was accurate and user friendly to check the speed of our internet

You can use a Bandwidth limiting software on the appropriate laptop that can set an Upload and Download speed limit on any Internet accessing software: it is a fair-priced commercial s/w called 'Netlimiter' and you can download the 'PRO' version on a 28-Days evaluation from: http://www.netlimiter.com/download.php
Very handy to limit each application bandwidth especially Data transfer from your Laptop when using a browser (such as IE/Firefox/Chrome) at the same time as a Peer to Peer application (such as Azarus/Edonkey/EMule).

On a on a surfboard modem would mean that you are only connecting at 10 Mb as opposed to 100 Mb

If you have a router it may well be a setting on the router.

otherwise I would look for a cable fault or network setting.

In theory it will not make too much difference if you only have a 5mb high speed connection.

In practise it may mean slightly slower pages on the INTERNET.

Start with checking you network settings for you wired connections more so in the properties for your Ethernet card.

If you can, look for a FULL DUPLEX setting and set that to auto.

I would also look at maybe replace the network cable and check that you are also plugged into the correct ports on any router.

eg. modem to router is the yellow Port or WAN
router to computers is usually black ports or LAN (usually 1 to 4)

Try another web browser, and adjust your caching

The speed of that router is 100 mbps (wired) and 54 mbps (wireless). If you have a 1 mbps line, that router is more than sufficient. Your speed will change simply because someone is using the internet connection. Downloading, uploading, surfing, chatting, listening to internet radio, etc. Make sure no one is on, then test it to see what speed you get. Go to www.speakeasy.net/speedtest and select the server nearest to you. It is a very good speed tester.
Good Luck!
