AP350 not handing out IP address to some devices

  • 1
  • Question
  • Updated 2 years ago
We have a single client that has over 30 AP 350 across their different locations. At their main office they have 4 AP 350's and for the past two months there have been numerous instances of clients connecting to the corporate WiFi and then not receiving an IP address. The device will show in Hive Manager as connected but it has an APIPA address (no valid IP).

After a reboot of the AP it is connected to, the client will gain the IP address.

We have reviewed the DHCP address leases and scope which are fine and has plenty of free addresses.
We have verified the VLAN's are correct on the switch. This only applies to the Guest network though which does not have an issue. The Corp wifi that is having an issue is on the same local network.
We've reviewed the wireless drivers on the computers and uninstalled the factory drivers and tried with drivers directly from the manufacturer but no go.

The only way we can get the client connected again is to reboot the Aerohive.

All the devices are on the latest firmware and do not show any hardware errors.

Has anyone ran into this or have any insight?

Thanks!

Helo Mike

A start can be the client tool in the Hivemanager (Tools -> client Monitor). If you start the monitoring, execute an association at the client, you can see the DHCP request and the DHCP offer from the server. Maybe you can see where it goes wrong (as normally the complete dhcp process with IP-adress assignement is shown).

Alright, I'll make sure to utilize that the next instance of this that occurs. It's very spaced out on the occurrence of the issue. 

Thanks for the reply.

This is the log from the client monitor from a PC that is having the issue.

This image is what shows after clicking on the client.

Is there any reason that you're using TKIP, which will stop 802.11n data rates being used? Ideally you would be using WPA2 with AES only. Are you able to change that?

From the client MAC, that's Intel. 7260 by any chance?

Presumably you've tried the latest driver from Intel directly and not the laptop manufacturer?

Next time you do a Client Monitor, I would suggest you check the "Filter Probe" checkbox.  It gets rid of all those probe entries to make it easier to read the rest of the log.

I'm not sure what is going on, but you can see that the DHCP server is offering a lease to the client.  The client just doesn't seem to be accepting it.  You could try using VLAN Probe to check to make sure that the AP is able to access all necessary VLANs.

Also, you can see that the client is de-authenticated right after it connects.  This de-authentication is probably why they aren't getting a lease.  I've seen the second one before, but the first one is one I have not seen before.  Hopefully someone can tell you what would cause the "de-authenticated because the sta is cleared by cli"

And as Nick suggested, you should change to AES if possible.  TKIP is deprecated and should not be used unless you have clients that do not support AES.  It is not secure.

You may find the issue is related to whether or not the client attempts to associate at 2.4 GHz or 5 GHz. Can you clarify the driver version you're using, from where and what the hardware is?

We can see which band this is occurring on in your Client Monitor output, 2.4 GHz or 5 GHz, via a tool I wrote to show this easily.

http://csharppad.com/gist/79f435ad5ef500a50712

Click on Go, wait for it to return, scroll to the bottom and then type in the BSSID and click on Go.

Tool.Check("08EA449068D5");
Address: 08-EA-44-90-68-D5
Address Base: 08-EA-44-90-68-C0
Frequency: Band2_4GHz

Tool.Check("08EA449068EA");
Address: 08-EA-44-90-68-EA
Address Base: 08-EA-44-90-68-C0
Frequency: Band5GHz

Tool.Check("08EA449067A9");
Address: 08-EA-44-90-67-A9
Address Base: 08-EA-44-90-67-80
Frequency: Band5GHz

So, this actually is occurring in your Client Monitor output on a 2.4 GHz BSS.

Tool.Compare("08EA449068EA", "08EA449067A9");
Gives you the relationship between two BSSIDs.

Anyway, a couple of initial things to do:

  • Move to AES-only with WPA2.
  • Check that you've got WMM enabled.
  • Check that you've got U-APSD disabled.
  • Check that you've got 802.11k/r/v (Voice Enterprise) disabled.
  • Check that the driver is up-to-date using the version that is available directly from Intel, not the laptop manufacturer.

Lots of good info here guys. I appreciate it greatly. Not sure why TKIP is being used. I'm in the process of changing that to AES. Our Guest encryption is using AES so I'm not sure what happened when this was implemented. Will report back after working through these suggestions.

Thanks again!

Mike,

Any luck with this? I'm having the same exact issues globally and it only happens with the internal network. Our guest network has no issues, while our guest network does. Any ideas?

Did you ever get this issue resolved? I started experiencing this same issue. Internal network will not accept the DHCP lease, but guest network works fine.

Yes, and its been running smoothly in the last 3 months. What we encountered was that the Firewall policy under the User Profile settings was causing the AP's to run out of their IP sessions. And from what I was told was that the Max usage of IP sessions is 8000 and we constantly hitting that number, once the Firewall policy was removed the sessions averaged about only 90-100. That being said, I know most people would be worried about removing this feature but it did resolve our issues and we now just rely on our actual Firewall and access rules to filter our internal network. 

Please note: In the network configuration, I removed the Firewall Policy in every SSID's User profile, and not just our Internal network SSID. Goodluck!
