Network connected but not getting IP address

[calvinX]

Hi All,

Having a bit of a problem with one of the jacks on my network. When I plug my computer into the jack I get a network connected notification but no connectivity.

Here is my layout.

Cable from router to a wall outlet. Cable from this wall outlet to another wall outlet. Cable to computer.

I have a sneaking suspicion that I need to flip a couple of wires on the second outlet in order to get connectivity to the network. I realize this is not the best way to run the cable but I don't have much choice in the manner.

Any help is greatly appreciated.

Calvin

As long as all the pairs on both jacks "match", you are ok. Have you tried assigning a static IP in the rangeof your DHCP scope? See if you are able to ping another machine on the LAN....

so your layout is:
router -- wall_socket ======= wall_socket -- PC.

As a general rule, wall_socket to wall_socket should always be cabled 1:1 - pins should not crossover at all.

Because this is a (extended) router - PC connection, the other cable connections should also (both) be straight through cables, not cross-over connections.

A green link light on each end of the connection (i.e. one on the NIC, one on the router) is usually a sign of proper cable connectivity; any further problems are usually covered by driver configuration or networking protocol configuration.

That is not true about the link light. Just because you have a link light doesn't mean you have connectivity. I have seen it before where a bad cable will still give you a link light but not connectivity on some switches, hubs, etc.

But he didn't say always, he said usually which is true. 9 times out of 10, if you have a link light, it is a software or config problem....

note: each link light tests one pair, if you have link on BOTH ends you have 'tested' both pairs. there are more exhaustive tests, but that is a start.

I tried to remain child-like, all I acheived was childish.

I think it may be a broken wire on the line...not sure though but I am going to run a new wire
