I got 99 problems but my WiFi ain't one

Latest firmware for both the UDM and the switch?

Yep

What other devices are connected to the switch and which model is it?

Smart switch 5, I think. Just an RPi that is hardly ever used.

How long are the CAT5 runs approximately. UDM ——- Switch —— Video Call.

UDM - Switch is long, circa 20m
Switch to video call device is short, just a patch cable.

Unifi support have suggested not being connected to LAN and WiFi at the same time.

I'm very tempted to bin the whole Unifi setup and just get a bumper pack of TP Deco units to liberally sprinkle around the house.

After messing with unstable powerline adapters ("gigabit", but they kept dropping and needed power cycling mostly because they're old...) finally decided to get something shiny for the new house. 2x Mikrotik Audience APs were delivered yesterday, 3 radios and 2 gigabit ports each. Turns out the "sync" button isn't really plug and play, it just adds a few sec profiles and syncs them across. The rest of it still needs configuring. Took a bit to understand and was a faff, but now all the wifi configs are managed by CAPsMAN and the speed is at least at the same level as when I was using the unstable powerline. Spent more time this morning switching all the IOT things to its own SSID again. I still need to make it its own little network, currently everything is bridged together... Then I can tell the FTTH-ISP to turn off their unmanagable wifi and switch it to DMZ.

After messing with the network for 3 days (including paying a tenner to someone on Fiverr for support, who took about 4 hours in voice calls and teamviewer) I decided to get the ASUS XT8's and return these. VLAN setup was completed but the rates dropped significantly, and apparently there are multiple ways to it and not all of them work in all scenarios/devices. Few minutes ago I finally removed the VLAN things, everything is bridged again -- not bad in terms of speed, but not great either.

Nice. Let me know how you get on. Love mine.

Just got a pack of XT9s delivered. What a welcome change from the usual crap (and what a breeze to set up). Minimum 300mbps in every room, with some rooms (next to the nodes) up to 700. That's what my line is capped to.

This is with wireless backhaul.

Was there any way that you could check that this was what was happening, that it was down to packet loss caused by the USG rather than any other part of the network.

Some of my wired stuff occasionally drops out and I wonder if that is the reason.

Ace. Still super pleased with mine. Rock solid connection everywhere.

Was recently given these. No use to me in my application. Anyone interested?

We got Community Fibre 1Gb recently and it's great, but I bought a Unifi 6 Lite to help get it around the house effectively and I don't seem to be getting the advertised speed from it.

I've already got two UAP AC-LITEs and I get up to about 550Mb/s from them - what you'd expect.

But I get the same max speed from the Unifi 6 Lite, even with WiFi 6 devices (I've got a Pixel 6 and a new desktop with 802.11ax on the motherboard).

I've tried googling it and applying all the recommended settings to up the speed. Switching to a channel width of 80 got the UAP-AC-LITEs up to 550 max from about 250, but nothing else - including manually setting channels and power levels, and turning off mesh and band steering - seems to have made any difference. Ethernet cables all good, giving me 900Mb/s+

I was expecting to see 700 or maybe even 800Mb/s with WiFi 6 devices. Does this seem reasonable?

I'm on the verge of returning it because it just doesn't seem to be able to do the advertised speed. I know it's a first world problem but it cost £120 and my two AC-LITEs cost £70 max each.

I'd be interested in what speeds you were getting with your U6-LR AP @Velocio

Edit: Think I misread that and it's @atz with the U6-LR AP

Does anyone have any ideas?

Are you absolutely confident in the cat 5 cable?

Have you tested without the cable and without the switch to rule them out?

I can now confirm that I get the issue when I'm just on WiFi.

Soooo annoying.

You need to buy a Unifi AP for the study, then discover that it doesn't actually go at full speed, like me

Ah, you might have sparked an idea there.

I have a unifi Ap in the study, which is back hauled over the same cat5 cable to my UDM router.

Maybe the issue occurs when connected to that AP, because an issue with the cat5 cable. If I happen to have connected to one of the other two APs in the house, it might not recur.

I'll try disabling that AP next time I need to make a video call.

The advertised numbers are for link rate, not actual speeds/throughput...aren't they?

What link rate are your devices reporting?

https://www.broadbandspeedchecker.co.uk/guides/improve-wireless-internet-speed.html#:~:text=Throughput%20and%20Link%20Speed,-Wi%2DFi%20throughput&text=Wi%2DFi%20throughput%20will%20be,GHz)%2C%20frequency%20and%20congestion.

Sorry bit misleading to say advertised speed - advertised speed is up to 1.5 Gb/s, my understanding is that you could reasonably expect to see half of that, so 750 Mb/s.

However, people who seem to know what they're on about on the UniFi forums reckon you should be able to get around 800-900Mb/s ish if the stars are all in alignment.

You may be on to something though because these are my rates:

Desktop:
Rx Rate 866 Mbps
Tx Rate 866 Mbps

Pixel 6:
Rx Rate 1.2 Gbps
Tx Rate 1.2 Gbps

I'm wondering if the issue is actually my devices - 550Mb/s may be perfectly decent for a Pixel 6 even on WiFi 6 and those desktop rates are with the antenna just over a metre from the AP. But what proportion of Rx/Tx rate should I expect as actual internet speed?

Do you have the option of widening the band to 160 from 80?

Good question.

Nope. I've seen that some people seem to have/have had that option but 80 is as wide as I can go.

Ah you seem to need a U6-LR for that:
https://community.ui.com/questions/Unifi-6-Lite-doesnt-Enable-160Mhz/7e9e1e49-1429-4014-ad9b-4edb9d581627

But what proportion of Rx/Tx rate should I expect as actual internet speed?

I'd say its almost unpredictable. So many different factors go into it...you'll get whatever the environment in your home allows you to get.

We've got a Hyperoptic outage at the moment but once its back up (probably later) i'll run some speed tests from a variety of devices and distances from APs.

Ta. Although you don't need to now!

Just worked out why desktop was getting 802.11ac not ax speeds - as a Hackintosh it only supports ac. Restarted it as Windows 10 and I've got ax now. Did a speedtest, got 560mb/s ish which is the fastest I've seen so far.

Lazily and stupidly I've been using the Google speedtest that comes up if you google broadband speed test.

Just tried broadbandspeedchecker.co.uk - 756mb/s. Speedtest.net - 814mb/s.

tl;dr - I'm a silly sausage. But I'm glad my U6 Lite is behaving!

tl;dr - I'm a silly sausage.

Tbh you've actually done me a favour. I have been agonising about upgrading my APs for a while now and your experience reaassures me that I probably wouldn't see much of a boost if I did! It does sound to me like your new APs are acting as should be expected.

Yeah I'm getting up to about 700Mb/s real world now that the AP isn't in the same room, sometimes a bit faster. Wouldn't be worth upgrading for about 200Mb/s, although you can get faster WiFi 6 APs/routers.

I knew that but am bought into Unifi, like the features and more importantly stability/reliability.

I am getting nowhere trying to fix my video call issue.

Getting significant pressure from my other half.

So fuck it, I'm going to ditch all the Unifi WiFi kit and sprinkle TP Link Deco M5s around the house.

Will have a UDM and 3 APs going for grabs soon.

Does anyone know if I can keep the Unifi switches and use them as unmanaged components in the new setup, plugged into Ethernet ports on the Decos?

I have an IOT device for my solar setup which reports to the Victron Remote Management portal, and when it works it's great - but the insulated doors give the device real connectivity problems.

I bought this external antenna - and now I've got it out of the box see that it has two connections.

Do I need a Y cable to bring these together to plug into my device, or just ignore one of them?

I imagine they will be dual band antena, one connector for each. Looking at google images shows that some of them come with a Y thing, worth a try I guess if your device only has one port. if not, try both and see which works better.
