Need a cable?<\/h3>\n

An Ethernet cable is required to connect your computer to the wired (Ethernet) campus network. BUMC IT does not sell cables but cables are available from most computer stores.<\/p>\n

DNS Values<\/h3>\n

It\u2019s likely that your computer will discover BU\u2019s Ethernet settings automatically once you are connected.<\/p>\n

However, sometimes people do need to enter them manually, in which case BU\u2019s DNS values are<\/strong>:\u00a0
\n155.41.254.250
\n155.41.254.251<\/strong>
\n<\/strong><\/p>\n

<\/a>If possible, narrow down the problem to your computer vs. your connection.<\/h3>\n

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

<\/a>Renew your IP address.<\/h3>\n

Computers get their identification and access to the network using the address that is assigned to them. But this assignment can get stale or become misconfigured. A common fix is to release\/renew your computers IP address:<\/p>\n

Step 1<\/span><\/b><\/div>\n
\u00a0Press\u00a0<\/span>windows\u00a0<\/span><\/b>key and\u00a0<\/span>X\u00a0<\/span><\/b>key at the same time. Then click at\u00a0<\/span>Command Prompt.<\/span><\/b><\/div>\n
<\/div>\n
\"\"<\/span><\/u><\/div>\n
<\/div>\n
<\/div>\n
\"\"<\/span><\/b><\/u><\/div>\n
<\/div>\n
\u00a0Step 2<\/span><\/b><\/div>\n
Type\u00a0ipconfig \/release<\/b>\u00a0at the Command Prompt window, press\u00a0Enter<\/b>, it will release the current IP configuration.<\/span><\/div>\n
<\/div>\n
\"\"<\/span><\/u><\/div>\n
<\/div>\n
<\/div>\n
Step 3<\/span><\/b><\/div>\n
Type\u00a0ipconfig \/renew<\/b>\u00a0at the Command Prompt window, wait for a while, the DHCP server will assign a new IP address for your computer.<\/span><\/div>\n

<\/a>Firewall Interference<\/h3>\n

Are you running a firewall?<\/strong> Try updating it with a built-in updater, or failing that, download a patch from the manufacturer\u2019s website. If that doesn\u2019t work, disable the firewall to see if that resolves the problem.<\/p>\n

<\/a>Spyware<\/h3>\n

Could you have a problem with spyware?<\/strong> Please make sure that you have scanned and protected your computer as described on our\u00a0Spyware<\/a> page.<\/p>\n

<\/a>Viruses<\/h3>\n
