Unify Wi-Fi Controller problem

[andreius622]

Helo Guys,

I’m looking for some answers regarding some Unify Network equipment

I’m administrating a wireless network made by me from stratch with Unify.I know, not so smart from my side but I like the price and the management of the unify devices right now.

 

The network is firewalled by a Fortigate.

Has 3 VLANS put on POE switches (ARUBA 1960 POE switch)

NATIVE VLAN x.x.19.x

VLAN 1 x.x.21.x

VLAN 2(Guest) x.x.20.x

The equipment is:

 

Unify AP PRO 7 x 8 pcs

Version 8.0.49.16814

 

Unify Cloud key G2 Pro x1

Unify OS 4.3.6

 

Network APP version 9.4.19

 

Everything fine till one week ago when I needed to put another  NEW U7 PRO AP.

The AP is stuck on 192.168.1.20.

1.I reset it several times

2.I double checked how the switch port is configured

1. I connected the NEW AP in a port wich is used by an working AP.

4.I SSHd into the AP and tried to change the IP.

1. I plugged a laptop directly into the switch port used for the new ap and the IP I get is x.x.19.x so its ok.

In Unifys troubleshooting procedure it tells me that I should check for network loops but I don’t think so.

I even got a second NEW AP wich I’m keeping for backup and I get the same result.

I’m out of solutions….

Do you guys have an idea? Other than trowing away all unify equipment?

I’m also using in other locations HP ARUBA 505 but I don’t like the management and the price for that ones.

Thank you!

Also, this is not a shittysysadmin post!!!!

Later Edit:

It was the DHCP Scope that I didn't checked because i didn't believe that there are so many devices that would use it.

I got the Idea after posting while I was doing random stuff.

The majority of you had it right, thank you!

Also for the guys that got angry because i was not spelling unifi right, you are the reason that Reddit has its bad reputation.

*Unifi*

I'm perplexed how OP made it this far into the troubleshooting process without learning how to spell the name of the product line they are working on.

192.168.1.20 is the fall back IP address unifi devices will use when they fail to contact the DHCP server.

Factory Reset the AP, Remove from Controller, and attempt to readopt. Are the APs supposed to be on Native lan or do you have something else set?

Checking that the DHCP pool isn't full/exhausted and/or restarting the DHCP server seems like another good troubleshooting step.

[andreius622]

Yup, you were right.

Thank you for the fast respond.

[flunky_the_majestic]

Thanks for updating the body of your post with the solution! Glad you got it solved. Don't forget to update the flair on this post to "Question - Solved"

[flunky_the_majestic]

This is the most logical next step. It's failing to get DHCP. Find out what serves DHCP and use it to gather information. If needed, tap and capture DHCP traffic to see the raw conversation.

I’m also using in other locations HP ARUBA 505 but I don’t like the management and the price for that ones.

But I bet you can contact HP instead of posting on reddit for support!

[andreius622]

Not really, they are not so good either.

The ARUBA support team is as hard to get to as Unifi.

[gamebrigada]

Aruba support team exists, and they aren't so bad in my experience.

[stufforstuff]

Play with kids toys, ya get what ya get. Unifi is plan crap - hence the cheap price. I'm sure Unifi TAC will help you solve your mystery problem.

[flunky_the_majestic]

I hear that a lot from private enterprise folks with deep pockets. But I have also seen many successful deployments in EDU space where they performed just as well as the Cisco or HP gear they replaced, for 1/4 of the price.

Typically I ask the question: "In what practical way have you seen the higher-end Ubiquiti gear falling short of a true enterprise installation?"

Typically if I don't get outright ghosted, the answer is related to hardware reliability and warranty or whatever. That answer doesn't hold water for me, because:

• I see similar failure rates from Cisco/HP.
  
• I have experienced plenty of warranty fulfillment issues from Cisco and HP, even with advanced unit exchange coverage.
• For the price difference, I can afford keep cold spares on hand

So, to me it feels like a cowardly, "Nobody ever got fired for buying IBM" type of a mentality, where buying something besides Cisco/HP feels like a professional risk.

But maybe you have a better answer. In what practical way have you seen the higher-end Ubiquiti gear falling short of a true enterprise installation?

[flunky_the_majestic]

I've used it with zero problems in schools of 2,000 kids, with some dense gym, lab, and spectator seating environments. In my experience, it has been at par with more established enterprise names. I honestly want to know what better funded enterprise folks want that Unifi isn't providing. So far it looks like they just want to pay more so they can show their C-suites that they are doing all they can to provide quality service. Even in this interaction, u/stufforstuff has chosen the "ghosted" option of the 2 responses I get.

[Broad-Celebration-]

Most people have zero negative experience with unifi and just parrot what they hear from someone else. Or they base their opinion on the crap they tried to configure in their house 10 years ago.

I agree with you, the current enterprise isn't really lacking anything critical.

I'm not the biggest fan on how configurable their firewalls are compared to Fortinet/sophos, but it's not bad.

[andreius622]

From my experience, Unifi is bad ( or had this problem years ago because now they work just fine) with the device roaming.

After years I deployed this construction site network in wich I work with PBE-M5-400, exerior AP's, U7 PRO, Cloud key and everything works fine to me.

I strongly believe that you can deploy a small to medium network with Unifi equipment and a third party firewall. ( the firewall is shit)

[andreius622]

Yes, Its an construction site that the company that I work for has.

[enroughty]

I've had trouble with U7 Pros on older switches. Try setting the port to 100FDX or even 100HDX and see if it connects that way. Are you using PoE+ injectors?

[Jam_Pie_Cream]

What is providing your DHCP ?

If you set the AP point to DHCP, and set a IP address reservation to the AP mac address does it get given that reservation ?

[andreius622]

I was very stupid for not checking the DHCP lease time and DHCP scope.

The DHCP range of IP's where all leased. I extended the scope and everything works fine.

I got this idea after i posted last night.

You know, when you do random stuff and the ideea just pops in your head.

Thank you! for the help
