I am looking for some techincal thoughts on this issue since the Nintendo community and support agents don't know enough hardware or software to help me find the root of the issue.
I have a V1 Nintendo Switch which appears to have a BCM4356XKUBG Broadcomm WiFi + Bluetooth IC inside that has a max theoretical data rate of 867 Mbps. However, despite having the maximum MTU, extremely low latency DNS servers specified, having the router's and the switch's antenna array less than 3 inches away from one another with line of sight, using an open channel on 5 GHz WifI (scanned it using Inssider)...I still cannot break 60 Mbps with a reliable 350 Mbps wireless signal confirmed by 3 devices at a similar distance.
Any thoughts or ideas? Is Nintendo possibly limiting the bandwidth in firmware?

Hi!
Has anyone reached more than 65 Mbps? I tried many different options on my Asus RT-N66U, but I haven't got faster. When I connect to my WLAN, SGN shows only 65 Mbps, while router supports up to 450. If there is a way to get faster I would greatly appreciate to know how) I use 5GHz, WPA2-PSK network
Thanks in advance

Well, might as well respond to this.
Note is being advertised with 802.11N but it isn't exactly what you think. Usually if you see WiFi N you automatically think it's 150 or 300 or 450 in speed.
How they reach those theoretical maximum speeds is MIMO and higher bandwidth. (Multiple-Input Multiple-Output)
Now look at wifi routers or adapters. See a router with 150M? It has one antenna. See a router with 300M? It has two antennas. See a router with 450M? It has three antennas.
Now if you look at their specs you can see they support 20Mhz and 40Mhz bandwidth.
With single 20Mhz link the max you can reach on WiFi N is 72.2Mbps. With single 40Mhz link you can reach 150Mbps.
Now add another link and what happens? Possible speed doubles. Add another link and it triples compared to single.
See the chip/antenna in our phones (other phones as well) isn't simply capable of higher speeds.
The chip and antenna in our phone is only capable of single 20Mhz link. Add higher bandwidth -> more battery is drained. Add another link -> more battery is drained.
If I were you I'd take a quick look at the wiki page for IEEE 802.11 and read a little about the bandwidth, data rate and such. It's actually rather entertaining stuff.

My views coming from a network administrator's perspective.
What sort of Router are you using, what sort of files are you accessing / transferring.
just an example, do you understand there are various type of switches, Normal, Low Latency, Ultra low latency etc...
My point is there are many factors to consider before you can reach certain speed, N specify XX speed means it can reach that speed but criteria do matters.
I've been searching for a while and i just cant seem to find the answer. I just upgraded from an AC 1200 to an AC 1900 router. My note 4's wifi link speed on the AC 1200 maxed out at 867 mb/s. on 5ghz which is the max for AC 1200.
Now with the new router it still only connects at 867mb/s and not the max link speed the new AC 1900 router should provide.
I know it dosent matter, has nothing to do with why i bought the router and is plenty fast enough... but it's bugging me.
I just want to know if the N4 tops out at 867mb/s? Has anyone gotten anything higher for a link speed?
thanks!!
I certainly haven't gotten anything higher than that with my RT-AC87 and my Note 4. Only topped out at 700-something Mbps while being in the same room as the router itself.
Usually, the bandwidth numbers on these routers are inflated for marketing reasons anyway. Sometimes they mash together the total theoretical bandwidth for the 2.4 GHz and 5 GHz bands, sometimes they assume you're using 3x3 clients (I'm pretty sure the Note 4 and most other smartphones and laptops are just 2x2), and sometimes they conveniently ignore the fact that Wi-Fi is an inherently half-duplex connection (transmit OR receive, not both, so your bandwidth's halved for bidirectional communication).
Your new router is probably only a dual band. Two channels of 433 Mbs. = 867Mbs. I have a Nighthawk Tri Band router which will combine 3 channels to allow 1.3Gbs. However I have no devices that support triband connections. My Surface Pro 3 and Samsung Tab S only connect at 867Mbs. Even the new Note 5 specs say Dual Band for the .AC radio spec. I haven't seen any new phones with a Triband spec yet.

WiFi Performance
Moving on to WiFi performance we address one of the most critical faults of the P8: Lack of 5GHz WiFi. There were already some raised eyebrows during the official announcement where we couldn't find any mention of 802.11ac in any of the spec sheets, and indeed, the device comes without support for the higher frequency bands.
This raises some big questions about Huawei's choice of RF back-end and what exactly is going on there. Connectivity itself is provided by a Broadcom BCM4334, which is quite an ancient chipset by today's standards, as we first saw its introduction in 2012. Broadcom advertises max PHY rates of up to 150Mbps and upper layer rates of up to 90Mbps - and 5GHz is definitely listed as one of its capabilities. This is the same chip used in the Honor 6 and Mate 7, which did have 5GHz capability. In the end only Huawei knows what kind of decision-making process warranted such a significant omission of an every-day important feature.
Possible fix i will try tonight:

I changed my wifi from standby to always. Weird things started to happen..
Test1 = 8.5 DLL / 4 UL
Test2 = 2.4 DLL / 0.3 UL
Test3 = 8.4 DLL / 4 UL
In test2 i wasn't downloading anything what so ever.
On my tablet i have stable 70 DLL / 5 ULL in every test i do.
Damn this sucks! I was going to buy p8 lite, now I need to look somewhere else.
Still waiting for fix
m waiting for fix

For some reason my Huawei p8 lite doesn't connect to wifi using n wifi network. Is it a software issue? I am sure that router is fine since other devices connect to it using n wifi

yes, i have same problem.
This solution only works if you do not switch to airplane mode.. The best I have found is getting kernel adiutor and changing tcp to reno instead of cubic.
Because of some other Samsung specific WiFi 5 GHz connection problems, I've done some Speedtest.net testing with my current four Android mobile devices.
Devices: SM-T825, SM-T815, Xperia X Compact F5321, LG V30 H930; Network 5 GHz ac; internet 200/20 Mbps;
Comparing tests on the same home network to the same Speedtest.net server I noticed that while the ping was similarly low on all my devices, the SM-T825 had consistently Jitter values of 35 to 60, while all the others had between 1 and 5.
The other WiFi connection problem was with both Samsung tablets: recurring dead link (I think uplink , ??) when the 5 GHz was set to strictly AC. The aging T815, my main gaming device, had dead uplinks on 5 GHz mostly when in standby for a time, but my brand new T825 surprised me with dead link while connected, too. The Sony and LG have no such proplems.
Now I switched my router to 5 GHz mixed (a,n,ac), maybe that helps.
After extensive troubleshooting with my ISP's highest level tech support (I escalated my issue to the highest level) and ultimately swapping my Arris XB6 router/modem with a brand new one with a different chipset, my S6 Lite attains atrocious 2.4 GHz speeds.
Before people lecture me on how I should be using 5 GHz only, the fact is I usually can't because of physical limitations such as concrete walls, congestion, and and distance. What's interesting is how when connected to 5 GHz, speeds are fantastic and mirror other devices including my laptops, mobile devices such as iPhone/iPads, and even a wired ethernet connection to the desktop.
However, things quickly go to **** when using 2.4 GHz. I exchanged my S6 Lite and it's still doing the same. I tested it out in another area using a different AP with a different ISP using only 2.4 GHz and I got the same result.
When using other devices including new or legacy devices, they all kick the S6 Lite's butt in terms of speed. While I can often only achieve 6 -10 Mbps with the Lite, I get close to 70 Mbps on other devices and even with an old Nexus 7 2013 I get close to 40 Mbps, but not with the Samsung - connected to 2.4 GHz.
Using Wi-Fi spectrum analyzers signal strength and speeds are all awesome. I have a signal of around -37 dBm when on either 20 or 40 MHz channel bandwidth. I tend to get slightly faster speeds on my Lite via 20 instead of 40 Mhz. Channels are manually selected as Auto gives the worst possible speeds.
As such, I have come to accept this is Wi-Fi is an issue with the Lite and an not a defect per se. It's engineered this way. My question is though, how and why? Does Samsung use two different radios or "network" cards on the motherboard? And if anything, shouldn't the 5 GHz spectrum suffer before the 2.4 GHz? From past experience using Android TV Boxes, my issues have always typically been when connected to 5 GHz.
