This was a strange networking challenge I recently faced, something I just couldn't find documented anywhere. Waiting wouldn't help, it'd also never finish. Try again about 30 seconds later, and it'd act all normal, loading the page very quickly. Heading off to the Mail app, same deal, might work, might hang when trying to refresh my Inbox. Perhaps an early-adopter issue, I'm used to those.
As usual, persistence paid off, and was key to squashing this bug. Even during the initial setup, I quickly noticed problems with WiFi. I mean, I didn't even get past the initial questions about restoring my iPhone from iCloud without multiple time-out sort of warnings about my WiFi not working, as it tried to use my 5GHz channel of my Linksys EA This was aggravating, and a bit worrisome, as I began to think it might be the actual phone, especially resetting it to defaults didn't help, and since my device seemed to be experiencing the issues far more often than the other iPhone 6 Plus devices in the family.
I was stopping by the local Apple Store for a case anyway, so I made a Genius Bar appointment before heading over. I politely explained the speed and signal was excellent, and the WiFi indicator was staying locked on just fine. Likely some deviation from factory defaults. When back home, I opened a ticket with Linksys support. Why bother? Also, just in case they had heard of this issue, perhaps they could explain a fix or workaround.
After providing proof of purchase, it was immediately clear that I was at 13 months of ownership. This meant I was out of warranty.
I convinced them to try to work with me on a best-effort basis, and they did. But of course, they simply had me reverting to factory defaults, then reconfigure all my settings manually port forwarding, security hardeningetc.
But at factory defaults, I could see that the WiFi problem went away.
I also checked with the always-excellent Apple Support folks, who didn't have any big known-issues with It'd help me, Linksys, and Apple to get to the bottom of this. With those phone calls behind me, I knew I was getting warmer, that it must be about some settings that affect just the 5GHz band in my router that was different than factory defaults. I then found this hint, and post that give me the "a hah" insight into which setting I needed to look closely at:.
I was having the same wifi problem with my iPhone 6. I changed the following settings on my router and it started working. Admittedly, this wasn't a spot-on match for my situation at all. But it was a clue. Yep, that did it alright.

This determines the channels available in the list for both bands if you have a dual band router and the maximum EIRP "legally" allowed by the telecom authorities in the chosen country.
Maximum EIRP varies by nation and your max TX power will be capped by the regulatory domain if you have a powerful radio. For example, Canada's max allowed EIRP is 36 dBm while its max allowed TX power is 30 dBm, with Canada selected and antenna gain at 0 dBi, the radios will never go above 30 dBm assuming they are capable of reaching that of course.

For example: Android phones cannot connect to my UniFi network or iOS devices frequently disconnect on my network.
These can be confusing and difficult issues to solve for network administrators especially since in many cases the root issue can be difficult to identify. This article will explain how to approach issues like these and list some common causes. When a client device connects or fails to connect to a UniFi network, the process on the UniFi side is relatively simple and straightforward. UniFi has millions of APs in deployment that work with all manner of client devices without issue.
Additionally, UniFi does performance tests on hardware with a variety of client devices to ensure proper function. Outside of UniFi, there are many variables involved with all the different devices, network drivers, wireless adapters, etc. In most cases, issues assumed to be UniFi issues that are confined to a segment of client devices end up to be totally unrelated to UniFi.
In some cases, you can change your UniFi configuration to help adapt your network to the limitations of your devices. For instance, fast roaming may not work well with all client devices depending on how old they are, how these products roam by default, etc. Here are some good questions to ask when encountering such issues:. Many users mistakenly attribute any issue they encounter on a Wi-Fi network to the hardware connecting the devices or the internet service provider, using proper troubleshooting and not assuming a particular explanation will help you resolve issues as quickly as possible.
When issues affect all devices, this implies that the issue is more likely to be a result of poor configuration or a potential performance issue on the UniFi side. If you encounter issues that are reproducible across all subsets of devices and appear to be related to UniFi and its function, please post on our community or contact UniFi support for additional help.
One of the most common Wi-Fi performance concerns reported is slower than expected Wi-Fi speed. This is due to a number of factors:. This article will help users better understand what Wi-Fi speeds to expect, resolve common issues and optimize their Wi-Fi configuration.
When looking at Wi-Fi performance it is important to take a step back and consider how Wi-Fi is supposed to work. Wi-Fi offers benefit of mobility, scalability and convenience over wired networks at the expense of maximum throughput and stability.
With respect to client performance, modern Wi-Fi is designed to allow clients to enjoy the benefits of not being tethered to a wired network, while preventing any visible reduction in performance across its area of coverage.
Much of the concern about wireless throughput comes from a lack of understanding about how much bandwidth clients actually use.The forthcoming This is one of the primary drivers behind the increased peak performance and bandwidth of wireless APs and clients. Therefore, careful consideration of channel widths allowed on APs and the channel plan for WLAN deployments must be made prior to an enterprise deployment.
Channel Numbering First, let's tackle how channels are numbered and referenced in Starting with Instead of continuing to reference the 20 MHz extension channel swe will now reference the center channel frequency for the entire 20, 40, 80 or MHz wide channel. The valid channel numbers for various channel widths are: Channel Width Valid Channel Numbers 20 MHz 36, 40, 44, 48, 52, 56, 60, 64,,, 40 MHz 38, 46, 54, 62,80 MHz 42, 58,MHz 50, This results in channel numbers that may look unfamiliar to most WLAN administrators.
Simply remember that channel numbers increment by one for every 5 MHz increase in frequency.Ff14 direct hit tanks
This will probably be easier to reference through a graphic for most people. In the graphic below, identify the center of each 80 MHz and MHz channel block, follow it up to the 20 MHz IEEE channel numbers, then split the difference between the two 20 MHz channel numbers that it falls between. For example, the 80 MHz channel block in UNII-1 is centered between channels 40 and 44; splitting the difference gives us channel To recap: 80 MHz wide channels allow for five 5 non-overlapping channels in the U.
Note - In the U. It's clear that 80 MHz channels will be hard to implement in an enterprise setting that requires high capacity due to issues with channel re-use and minimizing co-channel interference.New girl meets world season 3
Even when DFS is used, only 4 or 5 non-overlapping channels will be available. And forget about using MHz channels in the enterprise However, it's not quite as dire a situation as that. There is a saving grace that will allow enterprises to take advantage of these wider channels on a "best-effort" basis. Let's step back for a moment - with The APs channel width was statically set at 20 or 40 MHz.
On the other hand, Practically, this means that WLAN administrators can allow the use of wider channels by APs and clients when all of the constituent smaller channels are clear. If a portion of the large channel is busy at the point in time when a frame needs to be transmitted, for instance a neighboring AP or WLAN is actively using a 20 or 40 MHz portion, then the AP or client can simply back down and use the primary 20 or 40 MHz portion of the larger channel that is clear.
Critical to this dynamic per-frame channel width procedure is the notion of the primary and secondary channels. This channel forms the core frequency segment that the BSS basic service set or AP radio operates on.
Based on the channel blocks depicted in the table above, the BSS will then automatically designate the primary 40 MHz and primary 80 MHz channels by extending the primary 20 MHz channel moving downward through the table. Only the 40 MHz and 80 MHz channels pictured in the table are allowed. For example primary 20 MHz channel 56 can only be expanded into 40 MHz channel 54 combining channel 56 and 52 ; combination with channel 60 is not allowed. For easy reference, just use the channels as depicted :.How should I read this?
Is the client using 40 or 80 MHz channel width? Is it possible to find clients using certain width? Channel Width Capability isn't available in the client table listings. So from here you can translated this into supported channel width. Might help. I'll try that. I'd like to find if any of the clients are using 80MHz as it seems it was left on by default and we'd like to switch to 40MHz width to have more channels. I've never had any issues with changing the channel width.

Related Solutions.At our business which is a large building with foot ceilings, roughly feet wide by another or so, though the large chunk of the building is in a foot by 80 foot area with one corner jutting off in its own area so to speak.
It provides good range as is, but i think its slowly dying. Lately we've been getting alot of authentication errors and it just vanishes and loses the connection on various laptops. We got a unify hd unit. But its throughput on 5G has been rather woeful, at times only 50 Mbps using Qcheck and performance endpoint testing, whereas the old netgear is still a solid Mbps even from 90 feet away or more despite the issues of connection.
Although last week when i tested this VT80 channel i was getting around Mbps on average on the unifi. In either case, 2G is pretty bad on either device, never really getting about 50 on any given channel.
Ive been trying different channels on the Unifi device but so far i cant get the performance up to par even with the netgear and even at close range toounsure why. I think other considerations might be the Aruba wireless access points, but cost starts to rise as the desire for speed does. If the unify worked well enough at close range we would have added at least two more we have also bought the key device to have one single ssid.Dynamodb auto generated id uuid
Obviously as the user count increases this will decrease throughput we have about 40 users, so maybe an average of 2 devices per user on wireless, maximum. Something is goofed up in your configuration. How did you pick that channel?
Have you used the AutoChannels feature to adjust your AP's settings? When i first tested, i left as is, out of the box, upgraded the firmware this one is the hd model not ac pro though, not sure if there would be a difference.
Auto gives me miserable results, usually around 15 mbps for some reason. It seems likely that the Netgear is getting good bandwidth because it's dropping clients, for whatever reason.
The Ubiquiti might be overliaded with eager 5Ghz clients clamoring for service which they can't obtain from the Netgear. Either way, the recommendation would be additional access points At this point i havent told anyone about the new access point.
Ubiquiti Wireless Networks
So the only things on it are my devices my phone and my laptop i'm using to test it. So the unifi isnt really overloaded yet. I have to agree that something other than the access point is causing an issue.
I installed these units at my church and two cover the entire building both first and second floor through the concrete walls and floor. We have a lot of steel beams in the layout of this building, not sure if thats a factor but its not for the Netgear. I even tried turning the netgear off as a test and also doing the test from 1 foot away, either above or below the unifi device which for now sits facing upward in the server room not mounted on a ceiling as of yet. But i've tried adjusting angles and being up close but its performance is really lacking and i'm not sure why.
If you use a VT80 channel width, you need a device that will actually support VT Very good points, indeed, and they speak directly to the unobtainable Mbps minimum goal. Breaking a bunch of clients to get a synthetic benchmark score is silly, but something's wrong when the observed results are so much lower.
Heck we could do that with N back in Surface Pro 3 days. Didn't work with Apple devices worth a darn, the backwards compatibility wasn't bend-over-backwards enough. Ubiquiti radiate WiFi from the front outwards. Very little RadioFrequency emits from the backside. For this reason, they are meant to be ceiling mounted. How is it oriented in the server room? And where is the server room in comparison to the center of the bldg? Is the Ubiquiti round or square?
Using a channel width of 80 will cause interference. Might be good for a single person at home, but rarely used by professionals in office environments.
