LAN connection

[MSR63]

This week I have been trying to ad a laptop or two on my network and I get Limited to no connections (on both LAN and wireless)

Can't figure what's happening. The only thing I can think of is that I am now full on my 3Com switches -- I need to add another.

Any ideas?

Are you getting an IP address from the network? Have you tried setting up a static IP address? Is the IP configuration on your laptops set-up properly?

I do get an IP address from the DHCP server, the laptops are also configured correctly.

The only thing that has happened prior - is that I added about 5 IP phones and two PCs - they tested and came up fine. It did max out my 3COM switch I might have one open port. The ports I plugged the phones into were already connected to thoses switches.

Obviously, if you're getting an IP address, then the laptops are getting a network connection. If you were out of switch ports, you wouldn't have received an IP address at all from DHCP because DHCP would have been unreachable.

It is possible that these laptops had a DHCP lease already and are just keeping the same lease when they can't reach the DHCP server. The best way to test this would be to take the laptops into your switch room and plug them directly into the ports on your 3COM switch. If you have connectivity there, then you may want to have the wireing to the desk checked for possible short or something like that.

While you're in the switch room, see if you can add them to your network from there.

Good luck,

Thanks for all the suggestions - I found the problem.
I maxed out my current DHCP addresses. I expanded my range and disable the auto find on my 3COM system configuration for our phones - it was constantly polling.

Now I am good to go -- Thanks

Glad to hear it! Thanks for letting us know what the resolution was.
