Problem getting IP address assigned on Ubiquiti AP

[Michael S]

I have just put together a point to point wifi to take our internet access to various parts of my farm yard. I have used Ubiquiti M5 Nanostations for the point to point parts and Ubiquiti UAP-AC-LR access points. My first jump from the house to the workshop works exactly as hoped and no problem getting good internet access in the first barn. In that barn I have an internet switch which supplies PoE to the access point and the LAN to another M5 broadcasting to the next barn. In the second barn I have another internet switch, no access point, just another M5 broadcasting to our student accommodation where there is another M5 receiving connected to an internet switch and another UAP-AC-LR. All the access points are the same network SSID and password, the problem is the one access point in the student accommodation can be found by my phone but when it tries to log on the access point won't actually issue an IP address. When I swap it with the identical UAP-AC-LR in the office it works as expected and when the office one is put in the student accommodation it has the same problem it won't issue an IP address. All the M5s are powered by their own Ubiquiti PoE injectors as they won't take the power from the internet switches. Each of the point to point bridges has its own SSID and each receiving M5 is locked to the M5 broadcasting to it which I set up before installing. I can log on to each M5 and see it sending/receiving very satisfactorily and see each access point on the Ubiquiti network management page.

Any ideas where the problem lies? I have learnt how to do all this from YouTube in the last weak so I may have overlooked something obvious to someone more experienced.

Solved my problem with some internet trawling. For anyone searching and finding this thread All the M5 Nanostations need WDS enabled which is transparent bridge mode. This apparently makes the three pairs I have set up relaying to one another appear as a direct cable link to the other clients on the network.

Next week I will cause myself more trouble by trying to set up an 8 IP camera system with most of the cameras spread round my new network with only two of them on the building with the HDR in it.

Be careful with your setup when running IP cameras on the same physical network as your phones/computers.
I did this and did not realise that most IP cameras broadcast their video continuously to all devices on the same network (even if the devices have no interest in the video).
The result was that all devices on the network (with wifi worst effected) get flooded with video.

Ethernet wired devices seemed to manage OK with this (just about), but wifi devices like phones etc did not perform well.
In the end I had to make all cameras use a wired connection and used a different VLAN and subnet to separate the cameras and NAS from the rest of the network.
Then network speed returned to normal.

You can also use managed network switches that have IGMP snooping to disconnect the broadcasts from devices that aren't interested in the video, which can help.
Your setup situation maybe different from mine, but this was my experience anyway...
