Wireless N?

Where can I go to verify if my Wifi is setup properly to use wireless N? When I look at my connection info it shows speed of 65mbps. I have a netgear 3500 n router and my netbook which is sitting right next to me is connecting to at 150mbps wireless n. Seems to me that my NC is only connecting at G speed. Any thoughts?

you can have access speeds of that fast but the problem is the read write of the source on the nook you are trying to edit.

802.11G only supports speeds up to 50 Mb/s, so you're definitely getting N speeds.

[Q] Is there an app or method to tell if you are connected N or G wifi?

I am trying to troubleshoot my router, it does b/g/n
I have it set to g/n
I want to know if there is a way to tell whether the cappy is using the G or the N radio
I cant disable G, I need both on but I would like to see that the phone is using N if it can

quite simply, if the router you have isn't dual-band and is just using the 2.4GHz range and NOT the 5GHz range, then yes, your phone is connected at wireless n. but just because you have a theoretical max of 133 Mbps (or 300 Mbps if you bought the router within the past 6 months) doesn't mean that's the thoroughput you're going to get.
likely, depending on where you live, your internet connection tops at about 10 Mbps (that's megabits, not megabytes)... some places (especially if you have fiber) around 50 Mbps...
so realistically your phone is likely maxing out any downloads at about 2 megabytes a second... 10 if you have a really fast connection.

I am not asking due to speed
I am asking
Is there a way to tell what type of network your wifi is connected to, b/g/or n?
not just to my router, but anytime I am on wifi
on the phone?
on a XP?
on Mac?
PS
DD-WRT shows channels higher than 11 so those must be the 5Ghz channels
it is a WRT300N btw

the cappy doesnt have a 'n radio' and a 'g radio'
the cappy has an 'n radio' and 'n radios' are backwards-compatible to pickup older signals
you set your router to output g/n signals, your recieving device will pick up on the fastest signal
to test it, look at your data speed,
in windows click your wifi in the corner > status > SPEED
on your phone... Menu > Settings > Wifi > click your network > Link Speed
mac... i dont care.

Think that router didn't allow for auto switching between 2.4 and 5Ghz channels. You have to select it, so the one you select is the one you are using.I font think Lynksys starts auto switching until the 400N. On other networks,.use speedtest. Anything over 5.6mb (i think) is n speed.

[SOLVED] Local WiFi speed trouble

EDIT: SOLVED, if you encounter the same problem, use HTTP or FTP protocol, don't use ES Explorer.
Hi,
I'm experiencing a big trouble with the WiFi of my Z1 C6903. My router is : Freebox V6, WiFi N 2.4GHz maximum. My average speed (at 0 meter of him, for testing) with it, is 2-3.5 Mo/s max with a local transfer (with ES Explorer) like this : Router + Integrated NAS -> Z1, downloads or uploads have the same average speed.
So, for using the Z1 (and other devices..) at the maximum WiFi speed, I've buyed this router : Archer C7 AC1750, WiFi AC 5GHz (with three external 5GHz antenna).
On stock Sony 4.3 rom, i've got (at 0 meter of him) a speed up to 6 Mo/s (4-6 Mo/s is average). On a custom rom (SlimKat V7 for exemple), the speed is even worst (2-3 Mo/s, not stable).
The router cannot be the faulty, because i've tested it with a Macbook Air 2012, connected with WiFi N 5GHz, the speed is 22Mo/s (at 0 meter of the router, of course), and 8-9 Mo/s with 2.4GHz, and i've tested a lot of option on him (WPA2, AES, Channels, etc..).
So, what's the point ? The WiFi of the Z1 is realy crappy or i have a defective Z1 you think ? I'm lost.
Thanks for reading me.

it s about compatibility of XZ1 with ur router
try to test Z1 with another router
if everything go right u should know ur router (or maybe firmware of ur router) not compatible wiht ur Xperia.
test more and write more about it...
:good:

SOLVED
Thanks for the reply.
I have doing some investigation, and i found the problem (and meanwhile I upgraded the firmware of the router, Macbook maximum speed now peak at ~27Mo/s and i change aes to Disable Security in router, using mac filter instead).
When i use HTTP protocol (with Chrome) or FTP (with FTP Client) , i was able to download (and upload) at .. 23 Mo/s !
With ES Explorer, the maximum speed was only up to 6Mo/s (SMB or FTP) ! I don't know why ..
So, i don't think 23Mo/s was the max of WiFi AC, but it's already pretty decent and im now happy !

[Q] Slow Internet Speed on Wifi Nokia Lumia 1520

I am facing a slow speed using wifi on the lumia 1520. For sure there is something wrong with the wireless card or the drivers.
1. The internet speed while connected to wireless that i get on the 1520 is half or even more less than what i get on my desktop (connected wirelessly) or on my other phones (both being android). I get a 25Mbps download & upload both on the computer as well as on both the android phones. But on the Lumia it will hardly even cross 10Mbps for download and 16 Mbps for upload.
The issue with the speed is really strange because if i connect the phone to a 2.4 Ghz network i get upto 10 Mbps download and 16 Mbps upload speed.But if i connect the phone to a 5 Ghz N network then the download speed i get is 0.67 Mbps and upload 14 Mbps. Whereas both my androids have a download and upload speed of 25 Mbps no matter whether connected to a 2.4 Ghz or 5 Ghz network.
I have changed different channels on the router and have almost everything including resetting the router as well as resetting the phone but no luck. The phone is OOB lumia black OS.
Any ideas anyone.

What router do you have? My internet speed is 55mb down and 6mb up. I get 56 to 58 down and 6 to 7 up on my phone. I have an Asus AC1900 router. This phone has been one of the better phones I have owned when it comes to WiFi speed.

I have a netgear wndr 3700v2 router . I was able to resolve the 0.67 Mbps speed issue on the 5Ghz N channel by enabling WMM on the 5 GHZ channel however still the speeds are half of what is the internet connection speed.
The surprising part is that after enabling WMM the speeds on the note 2 when connected to the 5 Ghz N channel reach the proper internet speed as on a wired ie:- 39 Mbps but on 1520 they hardly cross 15 Mbps download .On the note 2 or my other android as well as my desktop the download and upload speed is proper on both the channels 2.4 as well as 5 Ghz. This indicates tht the router is fine.
I think i have to contact nokia support to have this checked. I am not sure as to what else to apart from this.

Same issue on a N97, wifi is muuuuuuuuuuuuch slower than 3G. Some messages I got about certificates let me suspect the preinstalled Boingo appli. All worked fine on my previous 5730.

G900-F real life WiFi 802.11ac performance benchmarks

Hi all
I couldn’t find detail benchmarks of S5 implementation of Broadcom BCM4354 2x2 MIMO 5G WiFi 802.11ac module and in the end decided to take u plunge and purchased Asus ac68u router. Went thru setting up 5G ac wireless network and current results look like this:
S5 connects to 5G ac network with link speed of 866Mbps
File copy from:
Gigabit LAN wired PC to Routers attached USB 2.0 HDD 29MBps (240Mbps) - bottleneck usb 2.0 interface
5G ac WiFI S5 internal storage to Routers attached USB 2.0 HDD 11 MBps (90Mbps)
5G ac WiFI S5 sandisk 128GB microSD card to Routers attached USB 2.0 HDD 11 MBps (90 Mbps)
I have 100/100Mbps broadband internet connection and S5 on speed test performs as follows:
72Mbps DL / 75Mbps UL (same connection via wired PC benchmarks at 94Mbps DL / 95Mbps UL)
I haven’t managed to achieve transfers speeds above 100Mbps from or to S5 in any combination. Can you please share your experience of S5 wifi ac 5G network performance
Related : thread by xenokc about S5 performance on 802.11ac network
Thanks

can you test with no encryption? wep/wpa completely off.

Yes, i have tried that, but there was no change. Router firmware is upgraded to the latest version / wireless test were done in close proximity (1 meter) to the router without any physical obstacles between (clear line of sight)
I'm really on a mission to achieve transfers speed in a range of 350Mbps-400Mbs on local LAN (which should be doable) but i cannot get pas 100Mbps!!

i'll try to test as i know AC should be able to do it.

802.11 ac provides a theoretical maximum stream speed of 433 Mbps or 900 MB/s across eight streams. That is under ideal conditions - maximum signal strength, zero interference, zero processing overhead and zero packet overhead. Many router 802.11ac chipsets only support four streams and due to real life channel contention, you aren't likely to see more than two or three 160 Mhz channels chopping that maximum speed to about 250 MB/s. All of those speeds assume channel bonding and quite a few routers can't bond 80 Mhz channels cutting that speed in half again (125 MB/s). Then you have real world losses due to signal attenuation, antenna inefficiencies and interference.
The S5 was the first smartphone to support two MIMO streams. But two is not three, so lop another third off our speed figure (or lop two thirds off for the iPhone 6 which only supports one stream). You simply won't achieve your goal with the S5 or any other current smartphone. 350 Mbps is the upper end of the maximum speed you might expect to see from a high end MIMO PC card under ideal conditions in the same room.
In real life and through a wall, you should expect considerably slower transfers. And the type of traffic matters too e.g. TCP traffic overhead often reduces speeds three fold over UDP streams in router speed tests.

Thanks for detailed feedback, but then there is no benefit from implementing ac standard or 2 spatial streams suporrted by broadcom chipset when performance is comperable to WiFi n standard? But then again how did those guys here managed to pull of such results:
382MbpsDL
or
436Mbps
whit same hardware setup?

..

what kind of latency differences did you see between the wifi phone and your pc to the same server? i'm assuming speedtest.net or something like that?

This is strange as for my G900I I've been able to run an Internet speedtest at over 11 MBps (88mbps) over wifi on wireless N at my university which I imagine would have multiple connected devices. Wireless AC should be able to at least match the 88 mbps I had achieved.

No, don't do this. You must setup a WPA2 security encription to get maximum rates on WiFi N and AC.
Then, remove storage bottlenecks. Don't use a external HDD connected to a USB2 port. Much less on the same router, since USB performance is much lower on those devices. You will need to use 2 devices on the same LAN. One wired for maximum throughput tests. A ramdisk or a SSD on the host would help too, since HDDS are limited to 120-80Mb/s transfer speeds.
If you are going to use a file copy as measure, make sure you make it into the internal SD card of the phone, since external will be limited to around 8-12mb writes depending on the card quality.
To test networks you would need ramdisk to ramdisk copies, but I don't know how to setup this on android.

This is rather interesting to follow

iPerf is available on android.
Quick measurement gave me ~110-169 Mbits/sec using default values on 40mhz WiFi N 5ghz setup.

Thumbs up. Finding someone that uses IPERF for measuring proper network performance is golden. It irritates the heck out of me to find video's of people using ookla to measure their network speed, or like the OP, measuring against USB2. That's like measuring the speed of your new 600MB/s SSD installed on a SATA 1 controller and wondering why you are not seeing a significant improvement.

iperf is a little more complex than ookla though, and thats usually why. same reason most of us dont compile our own custom roms
really, there isn't much need to get over 100mbs on wifi for 90% of the public.

Just picked up the s5 because no store will sell me the note 4 retail price.
Linksys WRT1900ac stock firmware, 5Ghz a/c connected @ 300Mbit
From the phone to wired linux box @ 1000Mbit
187 Mbit up 207 Mbit down but of course it fluctuates. I don't use wifi for anything that requires that much bandwidth anyway, but I do get my full internet speed of 175/30 using the phone.

This post is rather old, but some of us may still be interested.
I was looking for an alternative to usb cable to transfer files fast between a pc and galaxy S5..
I've used a wifi-300 stick connected to usb port on PC: TL-wn821N, and configured my S5 as a mobile access point.
An ftp server is running on the phone and an ftp client on PC. i am accessing the AP via AirmoreAP hotspot, with wpa encryption.
I am watching the download rate via crystal internet meter for windows.
And this is the result: 64mbps/56 mbps (DL/UL) UL reading a microsd card on phone and writing to sata2 internal disk on pc.
I am wondering if I can reach much faster speed with a wifi-ac stick.
