PfSense as DHCP server and DD-WRT as access points: DHCP not passing thru DD-WRT

Change to RAR and check your pm johnpoz

This is from your sniff on the client called client1.cap

It shows your client releasing 1.88, then requesting 1.88 and then the dhcp server giving it 1.88 with the ack,.

If your client is showing that it doesn't have an IP address, then that is on the client - because from this it clearly thinks it does. It even releases that IP back to the dhcp server before it asks for new one and gets back 1.88 again, etc..

But your client clearly shows ACK for the dhcp transaction when you sniff. So your issue is with client nothing to do with pfsense or dd-wrt.

I hid your mac because you had done that previous, and not my place to say what or what you don't want on public forum, etc. But it all the same mac, etc..

Everything is also in Status->System Logs->DHCP on pfSense.

So with this you are saying it is a Windows 8.1 problem?

Before making this post, I thought back about what you said that it was only this client so I ran a few tests.

With my Android smartphone, it does seem to get a IP from the pfSense and it can access the internet.

So you mentioned its a problem with the client…..so I want ahead and tested if the problem is the laptop or Windows 8.1

I loaded up a LiveUSB with Ubuntu on the same laptop and IT GETS A IP AND CAN ACCESS THE INTERNET.

I took ANOTHER step. Windows 8.1 Safe Mode with networking. Same thing so the problem is obviously Windows 8.1

So now what? >:( It is so frustrating that at the end of the day its the fault of a operating system that randomly decides not to work.

Obviously this is WAY out of the scope of pfSense so Im not sure what do to/ask anymore...

Yup. It shows basically the same thing johnpoz posted in the pictures.

Wired works.

Oh fuck this…..now it suddenly works. I plugged the wire, unplugged the wire, tried to connect via wifi, and now it gets the IP, gateway, everything thru DHCP.....

Same thing is in the logs for this, but its best to see with your own eyes sometimes what is happening with these protocols vs just a log dhcp server saying it sent offer, etc..

For you 8.1 problem - try resetting the tcp/ip stack. In elevated prompt

netsh int ip reset

or netsh int ip reset c:\path\resetlog.txt

if you want a log. Also check firewall settings and or antivirus/security software.. What is odd is it releases the address, so it knows it has it - just not showing/using it. Try the reset of the stack.

Now it works. Do you still recommend I do this johnpoz?

johnpoz

What it just started working out of the blue? Or did you actually do something.. Is it using a different IP than the 1.88 one? If its working then there would be no reason to reset the stack.

1: I plugged the laptop wired and it got a IP from DHCP
2: I unplugged it, wireless connected automatically and it got a IP from DHCP.

I did nothing else. Yes, ipconfig shows it got a .88

johnpoz

very odd.. But sounds like your good to go then.
