I had an old Unifi LR AP which worked flawlessly for years, but since support was dropped for it, I thought it was time I upgraded. I bought a 6LR expecting great things from it. I initially bought the wrong POE as the one I bought wasn't the gigabit one. I bought the correct one after working that out, but still have issues.

Most of the time it works fine, but for awhile, its on go slow. Devices connected to it get to the point where web pages won't load, my phone sometimes even thinks its not connected to the net, its that bad. I initially thought it was my ISP, but no issue for devices connected via cable. I then fired up the wifi on my router and thats been fine. I'll even switch between the router and the Unifi and see a big improvement in wifi speed.

I haven't played with settings on it, so its pretty stantard. There are only about 6 devices connected to it. I have 2 SSID's, one is both 2.4 and 5ghz and the other is just 2.4ghz, which is what my phone is connected to for better range. I'm running the latest controller and firmware.

Does anyone have any ideas what could be causing it to be so slow?

Hi, what channels and bandwidths are you using, and I take it you have no guest policer type things happening. Also under insights > neighbouring APs, are there other high level APs on the same channels as you. Do you have band steering enabled, if not its a good option.

Personally I would can the 2.4 only SSID and just enable band steer on the SSID thats using both bands.

Its using channel 11 and 46. There is no guest policy. No neighbouring AP's show up unless I have the wifi on the router turned on, which is very rare.

I don't have band steering enabled.

When I just had the one SSID, I found my phone would stay on 5Ghz, even when it was on the edge of the range, instead of dropping back to 2.4Ghz as I'd expect.

I'll get rid of the 2nd SSID and enable the band steering and see if there is any improvement.

Hi, and the bandwidths? and also look at dropping the 5GHz power to force the client to move to 2.4GHz sooner. Band steering wont fix the client hanging on to the 5GHz, but a single SSID with better power management might work better.

I've experienced this with Ubiquiti kit when I had WPA3 enabled and was especially common on Samsung devices too - I found dropping it back to WPA2 improved stability of the network.

Have you searched the Ubiquiti forums? Ubiquiti is just a slow motion train wreck now with it's issues, hence the reason so many people are abandoning the company and their products.

So far the searches I've found have all pointed to the wrong poe, which I've now sorted. What do you recommend instead of Ubiquiti?

Hi, have to agree with Steve, I have become less impressed in recent months with UniFi, the fact that their current memory leak on their linux controller goes un acknowledged, even though there are threads many pages long complaining of it. Currently I need to run 6.0.45 to stop the continual crashes, and yes I have stood up a completely fresh VMs (three times on different platforms).

But that all said, of all the APs that I have installed and manage of which there are several hundred, I dont see the issue you speak of, but none of mine are the UniFi 6 range, mostly UniFi AC-Lite or inwalls.

If you were to give up and go to another product (I strongly recommend you try understand whats happening first), there are plenty of great options, Ruckus Unleash, Aruba Instant are both top of the list and very solid, infact I would say cannot be bettered. Grandstream is pretty good to, installed a couple of multi AP systems recently and its a good solution.

Thanks, I'm a novice, but I'd like to get this sorted too. The old original LR was brilliant and I sort of wish I'd just stayed with that.
