Hey, just wanted to say i really like your Ubiquiti videos. I've been researching a lot of this stuff over the last few weeks and there's so many channels that go into insane detail and have really long videos explaining things that should only take a few minutes. Your style is very precise, quick and informative. You should upload more network videos! Really enjoy them, cheers.
You need to increase the channel width in the controller settings for the access point from VHT20 ot VHT40. You can do the same for 5ghz from VHT40 to VHT80. That is how you get the speeeeeeeed up!
Really good test. Too bad it wasn't a big change, but iPerf is always a good way to test raw throughput. I think the big advantage you will get from it is MU-MIMO. And just as a side note, if people are trying to avoid AP costs, Asus AX88U gives me 600-750Mbps with 160MHz bandwidth and 370-400Mbps with 80Mhz bandwidth (with two double sided drywalls in the middle). This is the only router IMHO that can face off with dedicated APs. EDIT: This is on Wireless AC devices. I don't have any AX devices to test the AX throughput, but I suspect it would only go up.
You're not the only one, FYI. I just went to post my config but retested like you have with iPerf and it's not what I was getting when I looked at this a few months ago. I am seeing similar speed caps, can't get over 300Mbps on my iPhone X, and my iPad Pro which should get much higher, caps out around 330-350Mbps, so not much better. I had this figured out and was seeing around 400-500Mbps a few months ago, so I will mess around with my settings and see what gave the best performance. I have the AC-Pro and ALSO considered going the HD route, but then learned that wouldn't help much with certain iOS devices, really depends on that 2x2MIMO or 3x3MIMO support.
So I was assuming that the access point comes tuned to use all that performance. It does not it turns out! I just learned (and now need to make a follow up video) that you need to configure it to use a wider channel band (thanks reddit). Mine was using VHT40 which was limiting. I tried both VHT80 and 160 and was able to go over 500mbps with those settings on an iPhone 8 Plus.
I'll test some things out next few days, so far biggest impact for improved performance that I've had is by turning off DPI (settings->DPI). Everything else I mes with has mixed results with no real improvement - if anything dropping speeds down to 50-100Mbps. I'm now seeing 350-400 on the iPhone X and 450Mbps on the iPad Pro with DPI off.
I added a follow up video with that setting here th-cam.com/video/jtK_lIw8We4/w-d-xo.html and linked in the description in case others run into this. Thanks Chris.
Hi. I'm not an expert but I do understand most of it. Thanks for that:-). My house has very thick walls, which make coverage an issue. Apart from the wifi speed, do you notice an improvement on the coverage/range?
Hi Herman, you are welcome! I didn't notice a difference in range. For best 5ghz band performance (speed) you want open air line of sight since it doesn't penetrate walls as easily as 2.4ghz. Placing APs where you will be heavily using your wifi devices would probably be best in your situation if you can run cables there.
@@reallyMello Thx for answering!! The thing is: I cannot run any cables, so I need a strong signal from the few wired AP's towards the other AP's-set-as-extender.
Many large operations find blanketing uniform coverage is more important than highest speeds at any one point. So that means cheaper APs and more of them spanning the area (properly tuned). If you have a tremendous amount of users that congregate around one spot the HD handles the most users though.
Thanks for the video. This information is exactly what I have been looking for over the past few days on various TH-cam channels presenting about thiese APs. I have been using an Asus RT-AC66U router for some time with RCN Gig internet. Here is my test speed: I was sitting about 16 ft away from this router in my living room and the speed test was 401 Mbps on my iPhone X. Do I need to switch to an Ubiquiti UniFi AP of any sort? If I do, I probably will not get close to 800 Mbps speed anyway though the theoretical speed of the AP is slated over 800 Mbps.
Hi James, did you check the follow up video? th-cam.com/video/jtK_lIw8We4/w-d-xo.html I found I needed to increase the channel width which got me to over 500mbps. I'm not sure if you'd hit 800mbps on a single device though.
You've got figured it out in the meantime right? If you still need a resolution, let me know. TLDR: the default settings are no good ever. They just work.
The maximum throughput is assuming that you’ll use both PoE ports on the WAP. You have to use link aggregation to achieve the maximum rated throughput. Your PoE switch has to support this in order to achieve this
Hi Fuziion, thanks for that info. I realized after in my followup video th-cam.com/video/jtK_lIw8We4/w-d-xo.html that I needed to set my wireless channel width from VHT40 to VHT80 which got me the speed I was expecting. I will probably enable link aggregation if the sum bandwidth of my clients exceed gigabit or if I get a newer wifi device that could use those higher theoretical limits. Thank you.

Thanks for the complement and sharing your speed on the Asus for comparison!

@@reallyMello indeed, yes you do want to make that change! I do have my VHT80 set, and originally also had VHT40 a while back.

Probably best mounted on a wall or ceiling with the U logo facing the towards you.
Agreed, just had it like this for initial setup
@@reallyMello Thanks for the video

@@fiderhit in this casei suggest you stick with an allinone router from local big box store as you wont see any real benefit without wiring in ap's.
for the unifi-HD (4x4) you can buy two unifi-pro (3x3).
How does it compares to that in a crowded place?

If you have a tremendous amount of users that congregate around one spot the HD handles the most users though.

@@reallyMello Thanks. Yes, I did. That was helpful too.
Is it absolutely necessary to have a Ubiquiti UniFi Cloud Key Gen2 Plus UCK-G2-PLUS if I don't plan on using any of their POE cameras?
John Ortuno the plus model would only benefit if you are using their cameras. Standard gen1 or 2 would work fine to run unifi.
how many devices can connect on 2.4G at the same time. and can this router be suitable for smart home that most smart devices support 2.4G only.
The AP-AC-HD specs indicate 500+ users
Are you using VHT80?
After the video I found I wasn’t. I changed to VHT160 and it’s much better now. Follow up video coming!

Yep, I posted a follow up video with the optimized settings
Uhhhh, English for the layman, please. Was the upgrade ultimately worth it?
Hi Glenn, check out part 2 th-cam.com/video/WS6Ien9YUiI/w-d-xo.html . You need to adjust some settings to get the full potential.
@@reallyMello Thank you. I definitely will.
