Wireless ac? - Nexus 5 Q&A, Help & Troubleshooting

Given my link speed I'm guessing the nexus 5 is wireless ac? If it was n it wouldn't go over 300 would it?

I Believe it does have 802.11ac and should be able to get up to 500MB

Yep, it has ac wifi. Theoretically good for gigabit speeds, but I think the highest hit so far is 800mb/sec. The main advantage I'm finding is that you can connect to the 5ghz wireless spectrum (vs the old 2.4ghz).

Whoops thought this was a N7 thread. Never mind... Freaking tapatalk search sucks...

Wireless LAN PC-to-phone transfer speed

Is it normal for me to experience a cap at ca. 2.5mb/s while transfering files from my pc to the phone through a wireless lan (802n, 2.4ghz router)? The transfer speed between 2 computers is close to 11mb/s
My phone is a Samsung Galaxy S2 I9100.
What app are you using? Could it be a free app, with an incentive to upgrade to pro?
Are you transferring the data onto the SD-Card? If do, what speed rating does your card have?
Oh yeah, and how is the speed from phone to pc?

Tried with WellFTP Server and MyPhoneExplorer. Same speed and both free apps with no pro version available.

Seems to be about the same or slightly slower (ES File Explorer doesn't show me transfer speed or time elapsed)
How about running a speedtest over your wifi network (with nothing else using bandwidth, obviously)?

how do I do that? Doesn't speedtest only work for internet connections?
Well, yeah. What I meant was to do 2 speedtests: one on computer, one on phone. Then compare the results. If they're the same, then there's nothing wrong this side of your router. I suspect the results will be significantly different.

What speed do you get if you connect your phone to the PC via USB and try writing files? I suspect it is simply down to the write-speed of your internal storage.

Ofcourse. It's about 6-7 Mb/s. Because of SDCard write speed.

So, to summarize, you're getting:
6Mbps from your phone to internet
6Mbps from your computer to internet
2.5Mbps from your PC to phone
all while using the same 802n, 2.4ghz router, right?

Exactly.
I should try my Laptop-to-PC just to see the speed also, because I realized that when I said that the speed to the other pc was 10mb/s, I didn't remember it is actually a wired network, lol. But still, is 2mb/s what I am supposed to get with n-wifi on a 2.4ghz router?

You're being very vague.
If you mean via HDMI then yes, it can be done.

WiFi Network Speed

Hello, I have a simple question.
My Surface connects to the router (ASUS RT-N66U) with link speed 270Mbps. When I copy files between the Surface and my Win8 desktop I get 4-5MB/s (~40mbps) in transfer speed. Is that all the Surface can manage? My laptop gets 25+MB/s (450Mbps link speed).
Can someone try and post results here?

I'm on my home network coping a file from my PC to my Surface over wifi. I am not doing it over the internet.
Why are you assuming the Surface or the network is the bottleneck? Try the transfer between different devices (Surface and laptop, Surface and desktop, laptop and desktop, etc. Also try downloading a file over the Internet if your connection is fast enough that it won't bottleneck that (some people have such connections...). Try over different WiFi connections if possible.
The first step when you find a problem is to isolate it.

I can push/pull 5-6MB/sec over 802.11n (2.4 or 5ghz) which seems to be the disk speed limit when using a class 10 SD card.

Ehhh... sorry i thought the RT versions shared a lot more. I have an ASUS Vivo Rt and if you open the Network and Sharing Center, click on Change Adapter Settings, right click on you wifi adapter (my case Broadcom 802.11bgn SDIO) select Properties and then configure.
It's strange that they decided to add something else to the soc.

Yep, tested mine. Read/Write doesn't matter, maxes out at ~5MB/sec - even on a "270 mbit" 802.11n 5ghz link with 5 bars signal.
So I guess that's as fast as the arm cpu can push bits.

No they don't - their speedtest shows 2/1.7MB second, which is 20/17Mbit. You and I and most people are seeing between 40-50Mbit/sec transfer speeds on your local network, which is not horrible for 802.11 wifi
This is a pretty good description of maximum throughput on 802.11
http://www.buffalo-technology.com/en/wireless-802-11-technologies.html
We're getting close to max speed for 802.11a or g at 5MB/sec (~50Mbit) - it's possible to get better performance out of 802.11n but you've GOT to use wide channel mode (in 2.4ghz) or 5ghz mode with multiple antennas (2T2R,or better mimo - http://en.wikipedia.org/wiki/MIMO) to essentially double/triple up your channels. Apparently (and not shocking at all) the surface might only have 1T1R
For the record: a Byte is eight bits. 2/1.7 MBps is merely 16/13.6 Mbps.

If i download anything from web or play store it takes forever. My normal internet speed is around 24 mb if i check on note is lower then 1 mb. I try almost everything exept of restoring firmware. On my galaxy S4 in same place in house i get some around 18-20 mb on wifi.

Have you always had poor speed or did it just start acting up?
Have you tried it at a coffee shop or a friends house that has WiFi?
Set to 2.4 or 5ghz?
Have you used an app like Wifi Analyzer or WiFi Overview 360 to see if you have neighbors overpowering your signal?
What WiFi channel is the tablet on?
Do you have a cordless phone in your home and if so what MHZ is it? Is the base unit near your wireless router?
.
How do I can change channel on my note? Seems like I get better signal on channel 11- 14

You change the channel in your router software.
can you check the ping time of your router within terminal?!
i some how had the similar issue, when I checked the ping it was so unstable, around 500ms!! and as i couldnt fix my problem i made a factory reset and it gone to 4ms ( a normal ping for mobile devices ).
Ok thank you to all. I change channel to 11 and looks like everything is fine.

Glad to have helped.....
Most people don't know that by default many 2.5ghz wireless routers default channel is 6 and if you and your neighbors are all trying to connect to channel 6 there is going to be issues.
With there being more and more wireless device and if you live in apartment buildings and housing plans you need to use the apps I posted links to in post #4 to dial in to the best wifi signal in your area.
I also run the app every month or so to make sure I'm getting optimal signal.
Nowadays my wifi is terrible slow with Note10.1.. DL 7-9mbps (speedtest, several servers), UL 9 mbps. My net is 100/10 and Note 10.1 tells me that the "link speed" is 72mbps. Everything is working SLOW, opening webpages is like back in the phonemodem age.
My laptop gets 80-90 mbps for dl at the same time. I even tried to change channel to better one, but no help... Im not sure did this started after the latest "stability" update from Samtoy.

is it slow on all. Or just on your access point.
i fix it
i had the same prob.my note N8000 wifi suddenly sluggish.... i fix it with opening the tablet, disconect the battery cable, push power button for 10 sec, leave the tablet for 2 or 3 minutes, reconect the battery cable, turn it on....n everything back to normal

[Q] Big Wifi problem on the Nexus 5

Hello,
I just bought a Nexus 5 and fell in love with it. :victory:
But there is one big and annoying problem:
When I'm connected to my router and use Wifi I get a lot of Wifi drops and sometimes it won't work at all.
Switching to Airplane Mode or turning wifi off and back on again and all these standard solutiones. (flashing another baseband version, turning router off and back on)
Sometimes for 1 min it's perfect! But then it's back in this very annoying problem. (On every other device it's so fast like it's supposed to be)
Is somebody out there, who shares the same problem and maybe got the ultimate solution?
Greetings (sorry for my bad englisch)

Also in the router settings?
I think you can fix this problem by changing the channel your that your router uses or by connecting to a 5GHz ap(if possible) but this sort of does the same with the channel 'trick'.
Download an app like inSSIDER or similar, find out what channel is least used by surrounding routers and change the channel of your router to that one.
If you need help with this let me know.

Thanks for your tip! I changed the channel to 11, now it's working and hopefully it will also work in the future.
I'm writing if it's now solved or if the wifi drops come back.
Nope, didn't worked...
Still no Wifi on Nexus 5... God that's annoying

I had the same issues with Linksys routers. Finally bought a netgear nighthawk and couldn't be happier. I can saturate my internet connection with the phone. And it outputs 1watt of power to each 5ghz and 2.4. So I get almost full signal on 5ghz on the other side of the house
