Aerohive issues

[EssentialRug]

Hi Edugeek,

 

We seem to be having an issue with one of our SSID's. We have three different SSID's:

 

SSID 1: This is what all wireless devices connect to

SSID 2: This is the one we use to enroll Chromebooks and they then pick up SSID 1 from G-Suite.

SSID 3. Guest Network

 

Over the last week or so we seem to be getting an erratic number of clients not being able to connect to SSID 1, however some devices work absolutely fine with no problem.

I am attempting to enrol Chromebooks this morning and am getting the 'Network not available' message after enrolling fine with SSID 2 and then picking up SSID 1.

I have performed network_diag --hosts command on an unenrolled Chromebook. All pass when connected to SSID 2, but when connected to SSID 1 they all fail with the message DNS resolution error.

 

Having looked through the Aerohive AP's through HiveManager both SSID 1 and SSID 2 appear identical, so I'm unsure where the problem here would lie.

 

 

EDIT: Just checking on two Chromebooks. One Chromebook picks up the correct IP address and DNS servers, however another Chromebook picks up incorrect IP address and DNS servers despite being connected to the same SSID...

 

If anybody has any ideas, any help at all would be much appreciated.

 

Many thanks in advance

Feeling pretty stupid that I didn't solve this earlier, but somebody had plugged a rogue wireless router into the network which was handing out the wrong addresses. Have removed and issue is now solved.

Are you going to publicly destroy the rogue router in the playground with a sledgehammer?

Go on I'm sure you're tempted!

I am seriously considering it!
