A sunnier or damper area than Ron-ski....
Hi all,

Have been setting up my new Ubiquiti network around the house and have just installed a U6 LR outside.

Whilst I've been amazed by the U6 Pros I've installed in the house and outbuildings, this seems somewhat underwhelming - indeed, I'm not even convinced my phone is actually using it, rather it's picking up the fainter signal of U6 Pros in the house or garden room.

Can anyone give me tips on how to diagnose/fix this? Standing right in front of it I get a 'half bar' signal, hence I reckon it's the U6 Pro inside the garden room that it's connecting to?

Set up is:
- UDM SE in the house
- 6 x U6 Pros - I think most of these are connected by PoE directly to the UDM SE - however a couple are connected through non-ubiquiti switches to it and then have PoE injectors
- The U6 Pro in question is connected through three switches unfortunately - UDM SE to a 24 port Netgear Switch next to it > this then runs to an 8 port Netgear switch in the Gym > this then runs under the ground to the Garden room to another switch, which then connects to the U6 LR with a PoE Injector.

I know this isn't optimal, but not an easy way to direct run a cable without a JCB... ;)

Could this be causing any of the problems? Certainly it seemed to be discovered fine and adopted into my Unifi network?

Any help appreciated!
 
Is it showing in the UniFi app? Are you sure all the connections between it and the SE are 1 Gbit and haven’t dropped to 100 Mbps half duplex or something.
 
For testing you can lock a device to an ap. This should help and stop your phone / testing device from jumping to another ap.

After that I’d turn all the other ap off to eliminate them from causing an issue.

Oh no, why should I do this out of interest??

They use it if a cabled backhaul isn't available, and it wastes wireless bandwidth. If everything is hardwired it's not necessary and is known to cause issues. Also disable automatic channel optimisation, and as suggested use an app to find the best channel. And spend some time working out power levels per AP, there's no need to have them all on high as an example as all this does is cause clients to hang onto APs which might not be the best one to connect to.

My hero of the day! I did that and almost immediately my phone connected to the U6 LR like magic!

Good point re power levels, although think this will take some tinkering!

The only mull I've got with channel optimisation is that as it's outside, I don't know if neighbours chopping and changing theirs will cause issues and mean having it automatically optimising channels might deal with this better?? Don't really know what I'm talking about though so happy to be wrong!
 
I think you'll struggle to find anyone on the UniFi forums that recommends it. :cry: Set it and forget, then if you start to notice some issues you can always change it by hand again.
