Can't connect to networks anymore? - Page 5

post #41 of 50
zomgiwin, you're good for a laugh..

The DHCP service in windows looks like it's stopped. You've made sure the services are running?

Use Wireshark to capture the Bootp process from your computer to see if it's getting a response for the DHCP server, or if your machine is refusing the reply's etc..

Filter out - only the appropriate udp traffic for and post the log file..

really?
like, the general level of competence on this forum is garbage.

my DHCP service is started, not that DHCP is the issue to begin with
(doesn't work static either... on an isolated LAN)

circles, i must talk in.... circles....

so, i've come to the solid conclusion that the userbase on OCN is generally not capable of making educated diagnostic decisions.
but um, if anybody has anything to add, go ahead, i'll check in every once in a while.

the OP does have a point.

from the info he gave us when he connected his laptop via wired NIC to his switch it did receive IP (i'm assuming that he has never connected his computer by wire, just over wifi).

New MAC with wired NIC, new IP. DHCP on the router side is not the issue here.

(if you have connected via wired LAN before, the previous lease in the DHCP could still affect the computer. You can try deleting the lease from the dhcp and try renewing said laptop again).

Assuming his network is "correct" the other suggestion i'd look at is using a LiveCD on the trouble computer. That would eliminate any problem with windows/software on the computer.

Your 169 APIPA address insinuates your host.. your pice of **** box, isn't getting a response to the DHCPDISCOVER broadcast on 255.255.255.255 when it's configured to do so. Why does your computer not get a ******* ip address when you statically configure the interface.... I don't know, maybe because you have your head so far up your ass you can't see out the **** lined through your eyes..

Your DHCP client (host, not router) may be ****ed. It's certainly not working correctly or you wouldn't be here looking like an e-thug trying to show everyone they are full of **** and you're the emperor of all is networking with your profound diagnostic skills.

IF you want to know why you're computer is failing the DHCP process then you need to analyze the authentication between your router and your machine. If you want to see why your default gateway is not responding or you can't arp onto your own local broadcast domain, you need to analyze the traffic on your machine.

I love you..

Now go do what I tell you when I tell you..

Switches never receive IP address, they are stictly a layer 2 device. If he thinks they should it just show how much of a dumb ass he is..

The whole point of using wireshark to wach the dhcp udp traffic between his machine and the router is to see what "exactly" is going wrong in the lease process. But I guess thinking that he knows everything can seriously hinder his ability to listen..

I wasn't trying to push my point as much as to tell you that being an ass gets you nowhere.

If your 'intellectual superiority' didn't simply exist in your own mind you'd have resolved this by now.

my mistake i didnt clarify, "it" means his laptop not his switch. His laptop did receive an IP when connected by wire according to him.

I then went on to say if there was a DHCP lease that was already assigned to his wired MAC then chances are it would still work and "retrieve" an IP. Clearing dhcp leases on the monowall router and attempting to renew the leases on the computer could show it's a dhcp server issue.

and wireshark would work as well.

anyways, many good suggestions in here on what to do.
