WiFi N

I see my device connected to my home wireless, but it says only 54Mbs. Wondering how I can tell if it's connected via b, g, or n. If it's n shouldn't it be up to 150Mbs? I get really good range, like a few houses away on my phone, so I assume it's got to be connected via n, but want to figure how I can tell on ym network and others I connect to.
TIA

Have you looked in the routers menu to see the connected clients and speed/type yet?
Also in SGS tools goto secret codes then usage stats and device info then wifi info

Have you ran speedtest while connected to wifi?
Also, if your router doesn't have automatic channel switching, you will have to choose. That should tell you how its connected.

I ran speedtests and used wifi analyzer and checked in my wifi settings. I see what channel I'm using and which are available, but nothing says connected 802.11b or 802.11g or 802.11n.

The further away from the AP you are, the lower your negotiated speeds will be. You can be right on top of an N router, but with the Broadcom WiFi chipset in the Galaxy S, you can only have a 72Mbps connection.
Lower throughput with further distances comes from error corrective algorithms. Lower throughput carries less errors at long distances.

remember our phones dont have dual band.
your router has to be setup to either be dual N band or on Single band,
but our phone will only pickup single n
and also as said above distance and signal strength can very.
as for running speed test... wont tell you much about your network connection unless your internet is faster than your router, and in north america thats hard to find...

Yeah I maxed at 72Mbps right on top of my router. I was just trying to find a way to tell if it's connected via b, g, or n.

If you are getting over 11Mbps then you are not B, so you can either be G/N with poor signal. Over 54 you are not G which means you are N.
Dual band only matters for 2.4Ghz and 5Ghz freq. ranges and being able to operate on them.

Absolutely correct..anything over 54 would be N but rate will degrade with distance and signal so it may be hard to tell what the initial connection was. Get close to the AP and see if you're over 54. Router/AP status may also tell you

Thatswhy I said run speedtest. My router is N speed,.but I only have 6Mb service. However, I usually clock about 5.8 on dl speed. My wifes netbook had a g speed card and maxes at 5.4.

That means nothing. Your internet is considerably slower than your router can handle. Speedtest ONLY measures your internet speed. The speed between your device and the router does not come into play unless you are connecting at less than your internet speed. Also, if you have a standard N router that is not dual band and you have something G on it, everything will connect at G speed.

I thought i knew the difference, but I think I got the big b and little mixed up again.
Ok, g speed maxes at 54 Megabytes or bits?
My internet is dsl, do its most likely 6 M bits or bytes?
And phone is bits or bytes?
My router is a dual band N speed, but its not set on the 5.4 setting and it doesn't auto change. It is MIMO, if that matters.
Thanks for straightening this out. Maybe I won't be the only guy that learns something from reading this.

wireless g speed is 54 MEGABITS per second which, without ANY overhead (impossible) you can see speeds of 7 MEGABYTES per second.
your dsl connection is 99.999999999% positively MEGABITS per second, so you could, without any overhead (again almost impossible), possibly see speeds of 750 KILOBYTES per second of actual bandwidth transfer.
there are 8 bits to every byte

No. Its 8 bits for every byte. Its mathematically impossible to score MORE bandwidth than is actually available.
Sent from my HTC Desire Z

To reiterate, 6 megaBITS per second equates to theoretical 750 kiloBYTES
There is not currently a DSL on the market right now that can do 6 megaBYTES per second.
Sent from my HTC Desire Z

Throughput is almost always measured in bits while size is always in bytes. Exceptions being download managers which usually (or as an option) display bytes since bytes (kilo or mega) are considered human readable.
For wireless modes (abgn) and freqs (2.4/5) most modern routers can do simultaneous modes and their supported speeds while only highend ones do simultaneous freqs. An exception being devices that support mode A since it is 5GHz 11Mbps.
Also for the OP.
Somewhere in that router it will tell you the mode you are connected at. My Linksys E3000 shows it in the dhcp client table. Others will show it in the connected wireless devices menu (i had a netgear once that displayed there)
Oh, another thing with some routers. Even though they support mixed mode, if you have a client connected at a reduced speed rate the router may reduce everyone to that rate.... but that is going to be for older devices.

Wifi issues?

Anyone else experiencing issues with wifi?
My reception in particular is quite low when comparing to other devices in the same area.
This is happening across different routers.
Any help appreciated

I have also some problem with the wifi.
If I am under 3 meter from my access point, there is no "problem". But if I am farest, my Note always disconnected. Every 3-5 seconds, the Note is doing a scan of the networks and cut the connection. With others phone I don't have the same problem. For example, it's impossible to listen to radios with wifi, download some stuff, there is always disconnection.
I saw that some other android phone had the same problem, is there a solution for the Note?
Thanks for your responses and sorry for my bad english.

Yes I've found wifi to be worse than my old desire

Most of the Samsung made devices I have seen recently for Wifi are pretty much crap. Not sure why but most have weak wifi signals. The Galaxy S2,Nexus S and the new Samsung Note are pretty much all the same as far as Wifi signals are concerned.

So I'm not sure if this is related, but it sounds like it might be. My note can't see my 5ghz wireless N. Anyone experience anything like this?is

Probably the Note's antena is a 2.4 GHz one. 802.11n != 5 GHz only. I learned that the hard way with my home network.
Which is a real bummer. I didn't know Samsung's devices had crappy WiFi, as it's the primary means my mobile devices get online.

My 2.4Ghz notebook makes 150 mbps speed, why Galaxy Note cannot use 150mbps? Actually the maximum speed is 65mbps even near the AP. I can't use DLNA, because all the videos are glitch with this speed. Can anyone explain is it possible to increase the 802.11n WiFi speed?

I was pretty sure its supposed to be dual band. I thought id resd other people had used 5ghz. Anyone have any experience with this?
Also my reason for wanting to use the 5ghz band his nothing to do with bandwidth and everything to do with the horrible. 2.4 ghz congestion in my apartment. If I'm near my router it's fine, but in other rooms I get wildly fluctuating speeds on 2.4ghz congestion(regardless of the device used).
Sent from my GT-N7000 using xda premium

It is not necessary to use the 5GHz band for 150mbps speed. It is enough 2.4 MHz.

I was going to get the unlocked Note to use ONLY on Wifi and maybe with the h20 prepaid at&t prepaid sim. This Wifi problem has me worried.

Well if it makes you feel any better, I am having no wifi issues what so ever, other than I am getting the sneaking suspicion it just doesn't support 5ghz bands at all.
Anyway, my 2.4ghz n is working just fine.

afaik generally speaking 5GHz quality deteriorates much quicker with distance and obstacles than 2.4GHz - it probably wouldn't be any better than 2.4 GHz.
Btw can someone measure .g and .n max speeds ? If I remember correctly SGS2 peeked at 32mbps no matter of the connection type so if Note does 65mbps then wifi in SGS2 and Note aren't identical. On the side note: SGS2's wifi is really crap, HTC Sensation's XE wifi works even with couple of walls in between the router I can browse the net, download etc. without problems, while SGS2 is close to unusable at that distance. I really hoped Samsung had learned they lesson with crap wifi implementation sadly this doesn't seem to be the case :/

Well I can tell you that in my apartment, the 5ghz band is a much better bet. Trust me, I have tested it a bunch with multiple laptops.
As far as wifi speeds, the fastest I have seen is roughly 30mbps on a rock solid 50mbps fiber connection.

I can confirm the same with the Note. The speed with 5Ghz N is way better and dropoff at least in my apartment is much less.

> Anyone else experiencing issues with wifi?
WIFI-g works fine on my device.

Both 5ghz and 2.4ghz work fine on the note, with the exception of 5ghz @ 40MHz channels which the note can't see. Of course the 5ghz band deteriorates faster as you get further away from the router but in 2.4ghz crowded places its still better to use the 5ghz radio. It's really very individual, each has to adapt to his environment's limits.

Maybe just an issue with t-mo versions, or even more likely is your router. I'm 15ft away from my router and still pull down an average of 50mbps with iperf.

Using an asus N66U. Would love to test 802.11AC but don't have a capable router yet.
Also something that I noticed when testing this, my One really doesn't want to be told to connect to 5ghz wifi only. It refuses to (re)acquire an ip address after being told to connect to 5ghz, so even if I had an AC router, I'm not entirely sure how I'd force it to use 5ghz in the first place. So the iperf test above is using standard settings on the One, with "use best wifi perfomance" enabled under power settings.

Better WiFi speeds than my N4 and better signal strength too.

I haven't tested a local LAN connection, but for internet speeds the wifi is fine. This is using an Asus RT-N53 router, Wireless N, 2.4 GHz band on top, 5 GHz band on the bottom:
Speeds are great, only problem is the unreliability of the 5 GHz band on the router itself, but the phone is fine.
To compare my desktop on a LAN connection gets 33 mb down and same upload speeds as the wifi.

Speedtest.net gives me 61M down and 7.73M up, which is pretty much the same as my desktop computer gets.
Note that this is using CM10.1 on a 5Ghz network (Apple Time Capsule). When using stock firmware I'm unable to connect the the 5Ghz network at all, it just doesn't see it.

I have an Asus RT-AC66, and the WiFi speeds on my One are great - link speed is 433 Mbps. Speedtest shows download speeds of 74 Mbps on my 80 meg broadband connection.

[Q] Poor wifi performance

For those who have the device, how does your wifi signal strength compare. Sitting at my desk, I get no bars now where on my OneX I got 2 or 3.

Same issue here on a phone from O2 with the latest software installed.
Compared to an iphone 5 struggles to hang onto signal. Tried both bands as well, same issue.

Wifi on my Z1 C6903 seems really poor.
Connected to 5Ghz on a dual band wifi router situated in the tv room. I don't get any connectivity from my room which is around 10m away.
I used to get decent connectivity on my iphone 5 - speedtest of around 14mbps. I can't even connect to speedtest on my Z1.
On a sidenote - what is with the headphone button not working. Had to update to .534 after much googling. Also, the new firmware doesn't help the wifi issues. Who knows how long we'll have to wait for a fix ...which may or may not improve it.
Also, did try to turn off the wifi power saving "feature" as well. Didn't do much.
Anyways that's my feedback.

same here! very bad connection with the xperia z1.

Yep poor wifi performance, I hope we get a software fix soon

Wifi speed

So yesterday fios installed the quantum router which gets 150/150 speeds. When i do a speed test on my nexus 9 on wifi i get this: (edit) refer to first picture below
When i do a speedtest on my note 4 i cant get any better than this: (edit) refer to second picture below
What gives? When i first did a speed test after he installed it, i got 80 down. I shouldn't have to reset router as he did it a few times when instslling. The only thing that i changed was the channel to 11 my dad said his verizon notification thing in his pc said there was a lot of interface and to switch to channel 11. it can't be the channel thats causing the problem cause i did these two speed tests at the exact same time. I tried turning on smart network switch in wifi settings but it didn't seem to make any difference. Does the note 4 just not have good wifi hardware? Idk what else to do. Whenever i watch youtube it constantly buffers and it annoys the crap out of me i should not have to have buffering with a quantum router!
