Hello Everyone!

I am having issues with my new UniFi AP-LR. This is my first AP from Ubiquiti, and I am hoping once I get it setup that it will work amazingly, unlike the Aruba APs that I currently have.

First off a little information about my network. The network I am on uses all Static IPs. There is no DHCP server or setup. I placed the AP on the network and changed my PCs IP to match the default IP of the AP to access it. Once I did that, I had no problem accessing the AP and getting into its settings. I went through the setup process you are given in the UniFi Controller (3.2.7). After completing that, I went into the AP and changed it from a DHCP to a Static IP and let it start doing its upgrade/provisioning.

After about 5 minutes the AP completed the provisioning and said it was disconnected on the controller. I went back into my PCs settings and changed the IP back to our local network. I then opened CMD and was able to ping the IP that I assigned the AP. I launched a new instance of the controller and logged back into the AP and was able to see it say it was connected. I went through the AP settings to verify everything was setup properly (using WPA).

Now that I verified all the information on the AP, I grabbed my Dell laptop and my iPhone 5. I tried to connect on my iPhone while my laptop booted up, and the only thing it did was keep spinning and trying to connect to the AP. Inside of the controller, it did say my iPhone was connected, but it never showed on my iPhone the Wifi connection bars at the top. I moved to my laptop and tried to connect there. I was able to connect to the AP, but I had the little yellow warning triangle in my task bar on my connection.

I tried to open a couple of webpages (Google, YouTube, Yahoo), but none of them connected. Again, I checked the controller and it did saw I was connected to the AP. So, I figured since internet was out, I would try to ping some local network machines from my laptop and vice versa. I was unable to ping any network machines, other than the AP, from my laptop and I could not ping my laptop from any local machines.

Since I was not getting anything, I figured I would try to change some settings on the AP. I went in and changed to and from all the different security options (Open, WEP, WPA) and the WPA Modes and Encryption. Still no luck, so I went into the WLAN Group options and enabled Legacy Support. Again, still no luck. During this time of changing the settings I was surfing the forums trying to find something. I came across a post that said to disable the Connectivity Monitor and Wireless Uplink in the Site Config options, so I tried that and still nothing is working.

So now, I am here typing the post hoping someone can help me get a solution to my problem. Any help and feedback is greatly appreciated and I am more than happy to provide more information if needed.

Thanks,

Ryan

P.S. I’ve also posted this to the Ubiquiti Forums, but haven’t received any responses.

Does the AP have the right DNS servers and gateway address for your LAN? Even if you gave it public DNS servers clients connected to it should still be able to connect to the internet.

But the thing is…if you have no DHCP, how do the wireless clients get a LAN ip so they can connect to the internet?

NetworkNerd,

Thank you for the reply. The AP does have all of the correct DNS information for my LAN.

It did not hit me until I just read what you said about the DHCP. This AP does not have an internal controller for assigning IPs. I am so used to using Linksys Routers and Aruba APs that come with virtual controllers for IP assignment that I overlooked it.

Now that I know what the issue is, I can properly set it up.

Thanks for the help!

No problem - once you get it going, hopefully you will see how wonderful Unifi can be!

That is what I am hoping! Much cheaper than the Arubas we are currently using. Plus, the Arubas have been nothing but trouble the entire time I have had them.

I was a Ubiquiti non-believer until just recently. I love their products.

I am hoping it will work great for us. If they do end up working great, I have a lot of Aruba APs that will need replacing. I am also looking into going with their AirFiber radios for our Police & Fire Depts and Water & Sewer Depts. The speeds they offer are the best that I have seen at the price they offer them for!

I was able to get it working by simply plugging it into the back of a Linksys Router I had sitting around and let the router use its DHCP to give it an IP address. I am now able to connect and get out to the internet and my shared drives on the network.

So, now the issue is being able to connect the AP to one of our Cisco switches and route it through a router. I am not going to use this Linksys for the network, so I was thinking of picking up one of Ubiquiti’s AirRouters and using it for the DHCP. Any idea how I will be able to accomplish setting it up for the AP to get its IP from the router through a switch?

Any router will do the job technically. Maybe look at ubiquity’s edge router or their security gateway for unifi.

Any DHCP server could do the job, if you have a vmware or hyper v you can just install a linux server with a dhcp server., if you hava a Windows server you could also enable dhcp on that. I would avoid any consumer router, it would defeat the job of having an enterprise grade AP to see your client without connection because the router has hang and is not leasing ip’s correctly. Is there any reason why you don’t have DHCP on your network?

We don’t use DHCP for security reasons and cause we are tied together with Fire and Police Departments. We decided on static to keep someone from just being able to plug into the network and go. At least this way, someone would have to have so knowledge to actually access the network without having an IP address.

These APs are also going to be setup to have hidden SSIDs and use WPA2-Enterprise for user login. On our internal network that does not access the internet for our Water and Waste Water plants, I am probably going to add a DHCP setup for the APs, but that wont be a big deal on that network since it isn’t accessing anything but historical data. So, it is mainly our business network that we are concerned with having DHCP on.

Any ideas to get a work around on our business network?

If you don’t want someone just plugging into your network, I would suggest using port security on switches rather than not having a DHCP server. You’re going to make a lot of work for yourself with record keeping. You can also break your LAN into separate VLANs with routing and rules to restrict access.

Fire = Vlan 10, 10.10.10.1\24

Police = Vlan 20, 10.10.20.1\24

Water = Vlan 30, 10.10.30.1\24

We currently do have it broken down into multiple VLANs with routing. I didn’t even think about using port security. Also, another issue will be getting changes approved and actually getting it done properly. Unfortunately I am not at the top of the totem pole so I can’t just make the changes I would like to make to our network. I will suggest the changes and see what comes out of it.

Port security with 1 MAC should work. If you’re using VoIP phones with a PC attached, you’ll need 2 MACs per port.

I’d make a little diagram with a short proposal.
