Can you get 1Gbps using WiFi?

So I recently had my Fibre upgraded to 900Mbps.

The actual connection tested on the WiFi 6 router shows 1Gbps and connecting via Ethernet I can get 980Mbps.

However connecting via WiFi on iMacs, MacBook and phones which are all WiFi 6 the most it can get is around 600 Mbps in close range and tails off to 400 Mbps on the other side of the house or in the garden.

So the question is that the expected and is there a way to get the full 1Gbps on devices?

Is there a specific WiFi solution I can plugin to the Ethernet and assume disable the routers own WiFi broadcast to avoid conflict?

Also if the cost is worth for getting those 40MB/s potential being lost?

Or is it a case those devices top out at 600Mbps even with the best antennas

Also getting a weird case on my phone the upload beats download.

Looks like they don’t actually bother restricting it to 900Mbps.

The SmartOS/OpenWrt seems to be one of the better routers I’ve seen.

This is common on symmetric lines. Uploads will often test faster than downloads.

As for the speeds you are seeing, they are normal for WiFi6. You might be able to tweak some settings to force it to burst to 1Gbit on WiFi, but this would depend on your hardware.

Would splitting into separate 2.4/5 help or would that actually hinder it? As far as I remember both are useful for coverage.

The channel seems to be clear so it’s not a case of interference.

I tend to always split. I prefer not to allow auto switching between 2.4 and 5. I will connect each device to my preferred frequency.

What kit are you using?

It’s an Adtran 854 version 6.

Ah, I was going to try to help with the settings but I’ve no experience with that brand. I’m fully Ubiquiti here.

I honestly don’t believe you have a speed issue on WiFi6 though. I would expect around what you are getting. I have some pretty hefty UniFi kit on WiFi6 with wired APs all over the house and I still only get around 700Mbit on WiFi6 (sometimes bursting to 1Gbit for a short period).

Also depends on the clients and how many spatial streams they support (2x2, 4x4 etc). There are many factors involved.

I can over a Gig on WiFi but that is using “Enterprise Gear” (UniFi U7 Pro MAX) on 6Ghz MLO.

I don’t think splitting bands does much anymore unless the router and device is really old.

I’ve found it helps a lot with some badly designed client devices that feel the need to constantly jump between frequencies. Sadly, there are still many devices with poor WiFi implementations.

Yeah exactly. My IoT WiFi is only on 2.4 as them devices tend to hate band steering.

Indeed, all IoT is on 2.4 here also. Some further away devices are also on 2.4 because of better wall pene-tration. All of my Apple kit is on 5GHz though for max bandwidth.

I prefer to remain in control of this. Band steering has never worked well for me.

The UDM SE is still running well along with my U6-Pro APs.

Might consider swapping out for U7-Pro APs at some point but just don’t feel the need right now.

I had to put a hyphen in pene-tration as the forum didn’t like it :face_with_raised_eyebrow:

Working in Cyber, we say the word all of the time. Give me strength.

Current setup is

But its going to be turning into VyOS as UniFi Firmware ain’t been the best recently.

Are the 2 lines for load balancing or failover mostly?

Failover both with 5 Static IPs

I’m going to try splitting.

Interestingly I can change Tx and Bandwidth but I haven’t a clue what is best.


Is there a HE160 option on the mode dropdown for 5GHz? This might offer some benefit with your MacBook, if it’s a recent model.

That said, not many devices can take advantage of higher than 80MHz on 5.

I can burst to 1Gbit easily on my MacBook Pro by connecting at 160MHz…

On Asus RT-AX86U with 2 Asus access points (Wifi 6 on 5GHz with gigabit ethernet backbone) I get max 600-700Mbps on WiFi. I used to get significantly less on the same equipment, which at the time I had narrowed down to something to do with weather radar frequencies and Asus limiting their devices on purpose, but it seems something about that has changed.

It’s an Air on the M2 chip ~2023.

So I’ve split, turned off 2.4 which seems to get 130Mbps max.

Using 5GHz and unchecking legacy I’m getting 750ish now on it.

I did try swapping channels but the auto seems to be picking the best with 149.

Phone seems marginally better but hard to know with limited tests.
