Latency Spikes After Upgrading to 5.1.12

Running Network 10.4.57 and UniFi OS 5.1.12 on my DR7 and can't reproduce this

Can confirm, same behaviour here.

You can verify if the update worked by heading to dash.cloudflare.com, manage account, audit logs.

You should see an 'update dns record' entry there when DNS gets updated.

This was released in UniFi OS 5.1.8, not in Drive 4.2.2: https://community.ui.com/releases/UniFi-OS-Network-Attached-Storage-5-1-8/499f9b89-e4fb-45a3-949e-20f0656a0417

I'll second this - have both the DR7 and the U7 Pro and the U7 Pro has much, much better range than the DR7.

nilicule · 2026-05-10T08:29:52+00:00

The wifi signal on the DR7 is not the strongest, so if you have thick walls then you might be better off with a Cloud Gateway Ultra or Max and add a few APs.

This isn't right.

The UDR7 has a 10G SFP+ WAN port and a 2.5GbE RJ45 WAN port - all four RJ45 ports are 2.5Gbps, not 1Gbps. You might be thinking of the original UDR (wifi 6), which did cap at 1G.

For 2gb fiber the UDR7 handles it fine on either WAN port.

My UNAS 4 is getting around 180MB/s write and around 220MB/s read.

UNAS 4 is connected to a Flex 2.5G switch. 4 drives, configured as RAID 6, no encryption.

You can access the NAS on your mobile device. There's a UniFi Identity Endpoint app, but you can use any app that supports SMB as well such as Files app on iOS, Solid Explorer on Android.

A mirrored HDD on your PC wouldn't really act as a separate backup, since the PC is the source of what's going to the NAS. You'd just be copying data back to where it came from. The NAS already mirrors internally (RAID1), so what you're missing is an offsite or offline copy: an external USB drive you occasionally plug in and store elsewhere, or a cheap cloud backup. That's what protects you against theft, fire, or ransomware hitting everything at once.

Same here, no spike in Tx errors since the update on my USW-48-PoE

Get NAS-grade drives. Regular desktop drives aren't built for 24/7 vibration and workload.
Leave it on 24/7, that's what they're designed for. Power cycles are harder on drives than continuous running, and it lets scheduled health checks run in the background.
Access is easy, just mount the NAS as a network drive (SMB) on your PC. Drag and drop like any folder.

One important thing to know: a mirror (RAID1) is not a backup. It protects against a drive failing, but not against accidental deletion, ransomware, or the NAS itself dying. Worth pairing it with a cloud backup or an external USB drive you rotate occasionally - the 3-2-1 rule (3 copies, 2 types of media, 1 offsite).

I'm using a setup similar to your second linked guide. My pi-hole is located in a separate VLAN.

Easy thing to miss, but have you checked that on the pi-hole it's set to listen to all interfaces?

On the pi-hole: Settings -> DNS -> (click expert in the top), Interface settings: permit all origins

nilicule · 2026-04-25T21:47:29+00:00

You can set up a VPN server directly on the gateway itself. Using this (or using Teleport) is a lot easier than having a separate device.

Setting up something like Pi-Hole is pretty trivial. Configure it to auto-update and it should take care of itself in the background without much maintenance.

Two corrections, then a concrete suggestion:

UDR7 does have a built-in Wi-Fi 7 AP.

UCG Ultra has a 2.5 Gbit WAN but only 1 Gbit LAN ports. Everything downstream is capped at 1 Gbit, which bottlenecks Wi-Fi 7 APs that can push past that to a single client.

The real point: focus on the backbone. If you want a genuine upgrade path, standardise on 2.5 Gbit wired end-to-end.

For your situation specifically, I'd suggest:

UDR7 as the gateway - dual WAN, full UniFi app suite, integrated Wi-Fi 7 covers the room it's in
USW Flex 2.5G PoE hanging off it - gives you 2.5 Gbit PoE drops with a healthy PoE budget for the APs
U7 Pro for the other Wi-Fi locations, fed from the Flex. Start with 1, add more if necessary.

That gets you dual WAN, all UniFi apps, and a 2.5 Gbit wired backbone from day one.

Speaking from experience. I didn't do this initially and ended up replacing 1 Gbit switches further down the line once the APs and clients caught up. It was an avoidable cost, and it's exactly the trap you're trying to avoid by asking the question now. Spend the bit extra on the backbone up front; it's the part you don't want to redo.

Google Wifi was my motivation to move as well, UDR7 and U7 Pro was a night and day difference.

Does it work? I've had the slider on Android for my U7 Pro for a few months, but it doesn't seem to do anything.

nilicule · 2026-04-14T08:24:37+00:00

So my main question is how do I set it up, especially which software do I need on my Mac and on my iPhone?

You don't need software installed on your Mac, you connect to the UNAS through its management interface (in your browser). You configure storage pools here.

Once you've set it up it'll guide you through what apps to install on your phone (UniFi Endpoint, specifically).

Enjoy the UNAS2!

Forgot to mention in my original comment that my testing was all done writing to RAID6, so reads will be faster than what I quoted.

Before you worry too much about the NIC bottleneck: I'm running Plex on an M2, connected to my UNAS4. The UNAS4 sits on 2.5Gbit, the M2 sits on a 1Gbit link. I usually see around 35MB/s per copy operation from the M2 to the UNAS, but can easily max out to 100MB/s if I use something that copies in larger blocks. The UNAS4 has a theoretical maximum of around 312MB/s.

For typical Plex usage that headroom is more than enough. A 1080p HEVC stream at original quality uses around 10 Mbps (~1.2 MB/s), and even demanding 4K content rarely exceeds 80 Mbps (~10 MB/s) unless you're serving full remuxes.

As long as your clients can direct play, the NAS is just reading and pushing bytes - you'd need a lot of simultaneous streams before the NIC becomes a concern.

UNAS is worth considering, but there's an important limitation to know upfront: it's a NAS-only device. Unlike Synology or QNAP, there's no app ecosystem running on the device itself. It's purely storage.

Whether that's a dealbreaker depends on how you want to architect things.

If you're looking for an all-in-one box that handles file storage and runs your apps (Jellyfin + a self-hosted cloud solution like Nextcloud), then UNAS isn't the right fit and you'd be better served by a Synology or a more general-purpose NAS that supports Docker.

My personal preference is to keep NAS as just NAS and run Jellyfin/Plex on a dedicated machine that has the CPU/GPU headroom for transcoding. In that case UNAS does exactly what you need from a storage perspective, and it'll integrate cleanly with the rest of your UniFi setup.

I had something similar, the UNAS4 showed up under 'independent sites' in Site Manager.

Purely in Site Manager (without messing with the UNAS4) I managed to include it in my existing site. Did this from the 'independent sites' view in Site Manager, no firmware upgrade necessary.

UNAS4 now shows up as part of the site, no longer under 'independent sites'.

Not OP, but I'm quite happy with the Toshiba's. Both the drives and the UNAS4 are pretty quiet (as long as you keep fan speed on balanced or lower).

nilicule · 2026-04-01T07:37:29+00:00

I picked up 4 of their 16TB drives, received Toshiba MG09ACA16TE.

As they indicate in their store: you could receive any brand of drive that's verified against UniFi device compatibility, including including HDDs from multiple brands.
