DNS Values<\/h3>\n
It’s likely that your computer will discover BU’s Ethernet settings automatically once you are connected.<\/p>\n
However, sometimes people do need to enter them manually, in which case BU’s DNS values are<\/strong>: If at all possible, try to narrow down the problem by (a) testing your computer with a different network jack or connection to see if the problem still exists or (b) testing another computer with your connection jack and\/or cable. Information from that testing will determine how best to troubleshoot.<\/p>\n The BU Residential Network (ResNet) uses a network speed of 10Mbps. While you are on ResNet, you may have connection problems if you set your Ethernet card to auto-detect the speed.<\/p>\n What happens<\/strong><\/span> Why it happens<\/strong><\/span> How to fix the problem<\/strong><\/span> 1. In Windows XP, go to Start<\/strong>->Control Panel<\/strong>->Network<\/strong>->Local Area Network<\/strong>. In Windows 7, right-click on the Network<\/strong> icon (computer shown with globe or cable in the lower-right corner), select Network and Sharing Center <\/strong>and then click Local Area Connection<\/strong> next to your network..<\/p>\n 2. Click Properties<\/strong>. 3. See your card name. Click next to the card name, on Configure<\/strong>. 4. After you click Configure<\/strong>, THEN<\/em> click on the Advanced<\/strong> tab. You will see a heading on the left, “Property” and a list on the right, “Value.”<\/p>\n 5. The properties may have obscure names. Find the one that controls connection speed. 6. Set the value for this property to 10Mbps Half Duplex<\/strong>. 7. Click OK<\/strong> or Close<\/strong> until you are back to your Desktop. It may be a good idea to restart your computer to make sure the new card settings are in effect.<\/p>\n Are you running a firewall?<\/strong> Try updating it with a built-in updater, or failing that, download a patch from the manufacturer’s website. If that doesn’t work, disable the firewall to see if that resolves the problem.<\/p>\n Could you have a problem with spyware?<\/strong> Please make sure that you have scanned and protected your computer as described on our Spyware<\/a> page.<\/p>\n

\nA network connection in a BU residence might seem to “hang” every few minutes, for anywhere from 10 to 40 seconds.<\/span><\/p>\n
\nThis problem can occur when an Ethernet card is set to auto-detect the network speed. In BU residences, the network speed is 10Mbps. A card that is set to auto-detect will connect at 10Mbps, but then every few minutes it will check to see if there is a faster connection. When the card tries to go back to 10Mbps after this check, a negotiation glitch may occur, causing the connection to “hang.” XP systems may be particularly affected by this problem.<\/em><\/p>\n
\nSet your Ethernet card to 10Mbps Half Duplex<\/strong> when using BU ResNet.<\/p>\n
