CORRECTION: In this video I mention the access point has 2.5Gb connectivity however, U6-LR only has a 1Gb connectivity.

@jeffm2787 2 года назад

Yes, I have two of them. I think it all comes down to pricing, if they went with a 2.5Gbps port it would cost a bit more and 99% of those installing them would never wire them up at 2.5. Also unless your a home user using the highly unreliable HE160 (for any AP) you just don't need 2.5Gbps. If your into transferring large amounts of data just hard wire. If your a gamer, just hard wire. If your surfing the web, porn, or whatever you do then you don't need that 2.5Gbps port. Would be nice, but just not necessary. The U6-Pro might have a 2.5Gbps port.

@Burnman83 2 года назад

@@jeffm2787 Agree. The thing is, tests of Crosstalk etc. showed that even with the 1g interface, the UBNT AP exceeds the bandwidth of the TP Link Omada AP featuring a 2,5g interface for up to (I think) 3 streams and only above that, the higher bandwidth interface gives you an advantage. Frankly asking: Show me ONE environment, where there are more than 3 people in immediate proximity to the AP going full blast with an up-to-date mobile phone or else. That is just not a typical scenario.

@coleharring 2 года назад

I could be wrong but when I was combing through the openWRT branch for the U6LR it does have 2.5 PHY but it’s restricted to 1GbE at a firmware or driver level. It could be a different Ubiquity AP and I haven’t flashed that on my own so I can speak to it validity just that I saw it in some of the openWRT firmwares.

@EsotericArctos 2 года назад

@Barrett Harrington As far as I know, U6-LR and U6-Pro both are 1Gbps PHY. The Enterprise version has 2.5Gbps PHY interface. This is somewhat of a failing on Ubiquiti's decision making process with these and limits the AP's throughput. Still better than WiFi 5 though

Be nice to see get an experienced viewpoint on some of the site-wide or wlan-wide settings such as Auto-Optimize Network, Enable Fast Roaming etc... simply testing with our own devices has massive limitations, given the diversity of phones and OS versions in use with some models several years old.

@JJ-gm1mk Год назад

Thank you for the video. Similar to at least one of the other commenters, I am curious if playing with these sorts of setting would improve range, as opposed to speed near the access point(?). I did watch your video on replacing 2 UniFi AC Pros with 1 UniFi 6 LR, but it didn't seem like you did as much adjusting of settings in that video. Are there any settings that would tend to increase the range of a UniFi 6 LR, particularly going through walls? Thanks again.

Band steering sounds good but setting it to "off" means that it is the client devices decision which band/AP to connect to... which is how it's supposed to be

@Rosscoff2000 2 года назад

Wouldn't it be better to set transmit power to max but also set a sensible Min RSSI so that devices that are powerful enough to get good two-way working at long range can do so, while devices with weaker transmit power won't make unusable connections or try to hold on to connections where they are no longer able to return a strong signal?

@michelogou6292 Год назад

Thank you, sir for that great video. Can i use the U6 LR with a Mikrotik Router?? Thanks !!!

@tlteal Год назад

Great video! I'm fairly new to Unifi and have everything setup/configured but the AP keeps disconnecting and going offline. What can I do to prevent that from occuring constantly? Doing so makes all the devices connected to it disconnect, reconnect, disconnect, reconnect....

@jeffm2787 2 года назад

Don't forget the U6-LR has pretty good gain on the antennas. That gives you the ability to hear those distant devices better. Not sure why people fail to mention antenna gain. HT40 doesn't work on the U6-LR for me, would be curious if it works for you.

@EsotericArctos 2 года назад

Gain in the AP is not really so great when your clients do not have the same gain. The AP may reach the client, but the client is not able to transmit back. Actual throughput is more important than theoretical gain devices have. HT-40 works fine on the U6-LR. If you have a crowded 2.4GHz area, it wil tend to drop back to 20MHz as HT-40 is more like Auto 20/40 and in crowded areas you will get better performance on HIT-20 in most cases

@jeffm2787 2 года назад

@@EsotericArctos Read more on Antenna Gain. Downside is more gain tends to have more directionality.

@andrewenglish3810 2 года назад

@InsideWire according to Ubiquiti's website the U6-LR-US only has a 1Gbit port on it, not a 2.5Gbit port like you mentioned in your video.

@InsideWire 2 года назад

You are correct, my confusion was with the U6 Switch which had 2.5gb capabilities. Will pin a post to the video for all.

@martinnm8022 2 года назад

Using 80Mhz channel is not always the best option at all. In a nutshell, the wider the channel the TX power is "divided" and more waiting time for clients to TX (20Mhz x 3 wait) to transmit. If you value stability, latency and range VS pure speed , I would go for 40Mhz channel, or even 20hz if latency is super important. The exception to this is aif all your clients are AX already and can use OFDMA better. Also, the more APs in the area using the same channel, the more unstable the wider channels are.

@smcomputersolutions 2 года назад

The reason it will have gone over to 2.4G network when you set the channel to auto on the 5Ghz band will more than likely be because it takes a while to scan the DFS channels and this can take up to 5 mins, the preferred channel being 5Ghz setting won’t have caused it to move to the 2.4Ghz

@thomasholmsgaard 2 года назад

Band steering and mixed opinions is because understanding of the ieee standards are missing. In a nutshell when activated an AP stops to respond to some of the association requests from clients in an attempt to nudge clients on to 5Ghz. Now this can be a problem for 2.4Ghz clients roaming and connecting. It is always the clients decision so Unifi do not automatically push the client to 5Ghz. It will chose to connect to 2.4Ghz if 5ghz signal is not within is acceptable range. Now if you have clients on the edge of the 5Ghz cell they will have problems. 802.11n is on 5Ghz as well ;)

@babasholaking Год назад

Hey good afternoon. I absolutely love your videos and in fact your delivery approach is so smooth and simple. That said I need your help for my home networks. I have subscribed to both Sky and Virgin Broadbands to ensure we don't have a down time. I have a 3 story building and i have cabled through the 3 floors. My network includes the following; Edgerouter X, Unifi U6 LR, 2 * Unify U6-Lite, 3 switches. I have decided to turn off the WIFIs from both Sky and VirginMedia in favour of the Ubiquity APs. I have the LR downstairs and Lite on the other floors. unlike you I live within a very condensed area with multiple channel consumptions and everyone uses 1/6/11 generally. I am finding it very difficult to find suitable channels per ap's. Even standing under each ap, I am only getting 65/70m. I am also using cat7/cat8 cabling mostly. I am just curious if there is any suggestions to get a decent speed through my house without resulting to mesh.

@InsideWire Год назад

If you access points are hard wired, there is no point in meshing them. Wifi is generally very busy and if you are in a busy area then it might be difficult to find a channel. Perhaps configure one access point as a time and see what signal you are getting. How are you seeing what level of signal you are getting, are you using the wifi man app or within the unifi network application?

@babasholaking Год назад

@@InsideWire thanks so much for your response. Yes I am using the Wifiman app on my iPhone to measure the speed. I actually move right beneath the APs. I found that my LR performs a lot better than the Lites. I just can not get the speeds for the 2 Lites to go beyond 90 when I am getting 750 or so for the LR a-bait on my iPhone 12 Pro Max

Normal for wifi man to show significantly lower upload than expected? I have an s22 ultra and get up to 920Mbps download, but the upload never exceeds 240Mbps on wifi man. My internet connection isn't fast enough to properly test, but I should have fiber installed next week

@EsotericArctos 2 года назад

I would not rely on the AP showing you what channels are busiest as this is only at the AP. You should do a proper WiFi survey, even if you only walk around with WiFi Analyser on your mobile phone, if you want to realy find the best channel. If you have a crowded 2.4GHz band, you should use HT-20 for reliable connections. 40MHz will be a less reliable connection if you have a crowded band. Just something to be aware of. All that aside, thanks for the video. It is quite reasonable for a general overview of the settings.

I just got a U6+ .... Testing with a M2 Macbook Air and a Iphone 14 Pro. I cannot get more than 500Mbps on sequential copies from my NAS. Also 2 clients downloading at the same time from the NAS are completely crippling the AP. Tested all possible channels/width combinations. Absolutely terrible.

Thoughput is not everything.. It get´s interesting once you have 10ths of devices with mixed technologies (802.11n -> 802.11ax) and you need to keep them all working / reduce jitter and retransmissions while operating in a RF noisy environment. You will quickly find yourself not using 80MHz Channel Bandwidth ;)

@dennisp8520 2 года назад

Isn’t the point to put older devices on the 2.4ghz so that you can connect devices that need faster speeds to 5Ghz where you can have 80mhz channels

@MichaelSmith-fg8xh 2 года назад

@@dennisp8520 It's one solution but 2.4GHz is noisy (bluetooth, microwave ovens, baby monitors etc) and often crowded (where I am it's not unusual to see 20+ access points trying to share the 2.4GHz band)... for noise I like running more than 1x 5ghz AP/Channel so that if the clients have issues on one AP/Channel they can silently transition to the other.

@fwaynedavis 7 месяцев назад

I know this is a late response, but this will help those following the conversation. Always set a bandwidth speed limit for the network. I suggest starting with something like 5mbps per user. This sounds counter intuitive, but everyone will "feel" fast because individually 5mb is plenty for RU-vid etc. what's happening is when there is a large bandwidth and no cap, some users will get all the speed, leaving very little for the rest. when all have speeds the network can supply at once, they all feel responsive. Keep increasing until you total usage is about 80% saturated, this will leave room for you to use a Vlan or private network for your business needs without bad customer experience.
