Full N mode - Galaxy Note GT-N7000 General

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.

Wireless G or N?

My current router is the workhorse wrt54gt from Cisco. My iconia runs fast at home. Will I notice significant increases if I upgrade my wireless?
To be honest, I did not notice going from wrt54g to Cisco e4200 dual band n...... quit a difference on my lappy tho. Iconia not so much.

Thanks. My laptops are older with G or on ethernet as are my ps3 and directv dvr's.
I connect my g/f's A500 and my A100 to my 2.4GHz N but never notice any difference. I suppose if you had 100Mbps FiOS or were downloading gigs of files on your LAN to the tab you might notice it.
As far as pure internet access goes, you won't really see a difference. Most people have internet under 54Mbps which is G speed. I use an N router to give higher speeds, because I stream lots of large content and stuff to my laptops and tablet. I can far surpass 54Mbps with the N setup. But the internet speed here is still just 7Mbps.... lol

Unfortunately some routers have limited routing capabilities. You can have 54 Mbps WLAN, 48 Mbps internet, but you'll be able to use only 16Mbps of it. That was the reason I upgraded to 802.11n. If you can utilize all your internet bandwidth and don't use network-heavy applications, there is no point in upgrading.

I see more difference with performance at a distance between an wireless router and computer operating at G standard and one operating at N standard. Possibly because the N routers I have had have been MIMO designs and I haven't had a G router with MIMO transmitters and receivers (not sure they are offered)
Guys: What kind of wifi internet speeds do you get on your acer iconia (using speedtest.net)? I have a real problem. I have a N-router - Linksys wrt150n and a fast comcast connection - 25Mbps. Most of the times I get 30-32 Mbps download with the wired LAN connection (and an upload of 5-6 Mbps). My wireless b/g/n laptop (when tested on speed test) gives me anywhere between 17 - 19 Mbps UP/5-6 Mbps DOWN which seems reasonable to me. However when it comes to Acer Iconia A500 tablet, I only get 1 - 2 Mbps download/4-5 Mbps upload (tested at the same time as laptop). I know iconia is rated b/g/n. So why is there such a difference? almost 1/10th. Is there anything that I am missing? My phone is 5 ghz and there is no interference that I can think of - If there was anything - it should affect the laptop wireless speed too. I have tried Dolphin browser, Opera browser, and the stock browser. Same results.
Please let me know if there is any setting on the tablet that needs to be enabled? Something else? I have fiddled with router settings also - auto vs n-only - almost same results.

Increase bandwidth higher than 65Mbits

As far as I am concerned the S4 has capabilities of WiFi speeds of up to 433Mbits.
I have a TP-Link AP and configured it as follows:
11n Only
Channel 11
20/40MHx
Max Tx Rate 300Mbits
Security WPA2 AES
However on my S4 I get only 65Mbits
On my ISPs modem/router (Arris) I have the same setup with Channel 6 and I get 75Mbits.
Even if I get very close to the device, the bandwidth won't change. I know I can't get the 300Mbits but I cannot understand why I can't get at least the same 75 that I get with the Arris device or even at least higher than the 75.
If I do a speedtest.net speed test at home via wifi I can get 117MBits over 5G wireless on my S4 so I'd say it was your set up mate. Let me know what you're using to test your network speeds and i'll do a comparison for you

Maybe flash another modem? Not sure if it will work, but worth a try
Me Gusta!
I'm not talking about data speed but local Wi-Fi only, not internet speed. I'm just using the Wi-Fi manager desktop widget which shows me the max speed for each network as soon as it connects.I know that this is approximate but since it always shows 75 on one and 65 on the other, it certainly means something

The highest link speed I get from my i9505 with N Type router is 72 Mbps.
We're talking about 2.4Ghz N300 here even when they are only 1 cm apart.
I've only ever got these speeds on every Rom and modem I've used, stock or rooted.

Data is data wherever is coming from. We're measuring the speed over the wifi here.
65-70 MBits is more than acceptable over 2.4Ghz. If you want faster change your router for a 5Ghz model.

Or buy another Smartphone with dualchannel connect… (My second Phone is "Huawei G700" and that connect my 2,4GHz Router with 135 Mbit/s! My S4 connect the same Router with 72Mbit/s only!)

Maximum AC wifi link speed?

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.

S6 Lite 2.4 GHz Wi-Fi issue

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.

Nintendo Switch WiFi Bandwidth much lower than hardware limit

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?
