Wi-Fi speed

Is the BA type b or g Wi-Fi? I can only get a peak transfer rate of 2-3mbit/s transferring large files from my work PC via a Linksys wireless router. This seems a bit low to me.

WiFi
It's b.

SD(HC) Tweaks (oh, and wifi too)

Do any tweaks need to be performed on the tp2 for SD xfer speed? I saw the tune-up cab posted on this thread (http://forum.xda-developers.com/showthread.php?t=446366) and was just wondering if it would apply to our phones as well.
Also.. Whats the highest xfer you get over wifi (SMB).. One large(ish) file.. I can only get about 530KB (kilobytes, not bits)... Signal strength is excellent. Laptop is connected via dual-band wireless-n. The average 802.11g client gets about 3.0MBps on my network. The wifi signal strength on my phone doesn't seem to impact the transfer speed (greatly).. meaning.. there is no flux between 5 bars and 3 bars. Doesn't that indicate an internal bottleneck? What bus does this wifi card 'ride'? PCI or usb?
DOH.. should've made a separate thread.

530KB (kilobytes, not bits) equal 4240Kb (kilobits) which is close to 4Mbps.

Once you figure out your bits/bytes come back and edit your post.
If you're getting 3mbit on 802.11g then something is wrong with your wireless, period. For a duplex connection (ie: one radio does send/receive) you'll get about 24mbit max. I get 22-23mibt typically on my wireless laptop to my access point here at the house. I haven't bothered to test the Tilt 2's wifi however.

I don't think I mixed anything up.
G notebook clients get about 3MBps or 24Mbps on my network.. N client to gigabit wired server (router is 610N, gigabit eth ports) gets 11MBps (I think)..
My touch pro2 comes around and gets 4 megabits or ~.5 megabytes/sec.. How does that happen? Probably for the same reason my zune 8gb (flash) gets those speeds. So what is that reason?
Wheres the bottleneck? Wifi antenna? Comm bus between wifi chip and phone storage? What do our wireless cards look like anyways? Perhaps there is one antenna. That wouldn't surprise me..
Regarding the SD isssue: I selected to mount the phone as a usb device instead of active sync.. I got about 3 MBps write. I think I need to get a Class 6 card.

Enabling wifi to stay on during standby and then putting it into standby actually sped things up... Anything remotely proc intensive tends to smack the wifi transfer around a bit. Its not really an issue of SD card access. But then again, the SD card access could be impacted by processor usage and in turn slow down the wifi.
There are a handful of settings in the wifi reg key BCMSDDHD1 that start with SD... Why? I need to fire up the dd-wrt router and see if this actually connecting at 54g.
btw: speed up was from ~430KBps to 600KBps.

I also have this problem with slow wifi connection and wonder if there iare any bottleneck.
I understand what you mean but people probably will get confused when you write about 5 megabytes/sec speed for tp2, dont you mean 5 megabits/sec?

[Q] AT&T tethering problems on file transfers

Hey everyone,
I've been searching and reading lots of threads and haven't found one that seems to address the problem I'm having.
So I have a Tilt 2 currently with NRGZ28's Energy Oct 20 ROM (installed earlier this evening). The problem is that I can't seem to transfer large (let's say 5MB+) files over instant messaging apps (AIM, Yahoo, MSN/Windows Live) or via FTP without having the file either fail with an error, or just sitting there with the completion time climbing higher and higher.
When I check Windows 7's Task Manager and click on the Networking tab, there's no bandwidth usage at that point. I can still send and receive IMs on all the networks at once, Outlook is still functional, web pages still load, but the files just won't move.
I have a similar problem when trying to view videos on Hulu. YouTube and other sites do better, but they stop to buffer far too often to make it fun. Even with 360p videos on YouTube, it stops quite a bit.
My signal strength shows 4 bars and H (3G).
I have the latest radio ROM for AT&T. I previously was using the factory ROM and thought updating the radio might help, but it seemed to make no difference.
Possibly related to this:
I have a laptop and a desktop. When I use the WiFi router app with this ROM, the laptop connects to it without problems, but the desktop, which has a Realtek Wireless N USB adapter, sees it, connects, and then most of the time has no Internet access. Even with the laptop turned off. The adapter is set for DHCP and all the usual default stuff, but it lists the gateway as being 192.168.1.2 or .0.1 (I forget which now), when the laptop lists .1.1.. A few weeks back, I could have both connected to the WiFi router in the phone without problems, and even copy files between the computers. Now the desktop works right about 1 in 10 attempts but works fine using the Phone As Modem thing with a USB connection.
But even using the USB connection, I still have the exact buffering or not loading at all, or not transferring files problem.
I found that using Total Commander on the phone, I can connect to my FTP server and upload a 35MB (the only one I tested) file very quickly without any problems. So the problem appears to be with tethering of any kind.
Speedtest.net usually reports about 1.0 or 1.1mbps incoming and about .3mbps outgoing.
I'm using MediaNet for the connection and have used most of the Energy releases over the past 5-6 months. I also ran Task29 several updates back. I haven't since, but I didn't see any difference before running it (probably 10 ROM updates) and then maybe 5 after running it.
I'm in Orlando, Florida and when downloading from various servers, I usually get 350K/sec, give or take. I can't understand how that's not enough to watch 360p YouTube videos. Sometimes they'll buffer just far enough ahead to not be a problem, othertimes I'm not so lucky and have to pause for 30 seconds to get a minute of video buffered.
The desktop is a Q6600 with 8 gigs of RAM and Win 7 Ultimate, the laptop is an AMD 2GHz with 4 gigs of RAM and Win 7 Home Premium.
Any ideas?
Thanks in advance!
Eric

Anyone?
I also just found I couldn't upload a 30 meg video to Facebook (I assume that's over HTTP port 80). I got about 10 megs out and then it just stopped transferring. Task Manager Networking was dead and time remaining kept climbing, but there was no timeout.
So it doesn't seem to be related to ports, but more so with outgoing data and tethering. And I have the same problems with USB or WiFi tethering..
Thanks!
Eric

Anyone?
Bump?
I just did a test on speedtest.net to Wichita (that's what it detects is closest, not that it's anywhere near Orlando).. Download was 1.93, though it seemed to sit around 1.8 megabits/sec during most of it. But these timeouts are still a problem. I really could use some advice here
Thanks,
Eric

WiFi performance?

Hi,
I'm connected to my LAN, router in same room, so signal quality is great.
Thing is, when I copy larger files from my PC over WiFi using any File Manager, speed is like 500KB/sec which is pretty low.
Any thoughts or ideas?

What are your speeds like just running Speed Tests?

11.5Mbit download, 3Mbit upload, that's what Speed Tests shows.
My laptop downloads the same files from my PC over the same WiFi network at 10MB/sec. I hoped GN would at least do more than 1MB/sec.
Sent from my Galaxy Nexus using xda premium

Sounds like its the apps problem if the speed tests show good down/up speeds.

I'm finding this aswell, It's really annoying me. On speed test I get about 7-800kbs which is ridiculous when I can download on my laptop over the same wireless network at ~6mbs (50Mbit internet connection). It doesn't bother me so much for installing apps and such as I they tend to be pretty small so its ok, the problem arises when transferring large files to the phone as it takes an age. It's also a problem as I was hoping to be able to stream my bluray rips to the phone, the video processor is fully capable of decoding the content but due to this annoying network bottleneck I can't play any films over around the 7GB mark and I've not got a prayer with my 20GB+ rips which over devices on the network have no trouble streaming.

Which app do you use to transfer?
Try to use different app.

I'm still waiting for my Nexus so i can't exactly comment on the device itself, but I use the app "SwiFTP" on my Galaxy S2
I think its an awesome app - all you need is a FTP client on your computer and WiFi connection.
SwiFTP basically makes your phone a FTP server and you can use your PC client to connect to your phone and browse/transfer files. Usually speeds range about 2-3mb/s for me which is fast enough
Give it a try! (cause i'd also like to know how it performs on the GN before mine comes haha)

speedtest gives me about 50Mb dl and 10Mb ul
My internet connection is 100Mb dl/10Mb ul

OK I tried different app: Wireless File Transfer Pro.
It runs on the phone, then you open a browser on PC and select files to upload. Doesnt show data transfer rate, but I can already see it's much better (I was refreshing the folder on the phone while 650MB file was being transfered).
So at least it's not hardware. (actually Ive read that GN has same WiFi chip as SGS2).
Anyway, sounds like it's all software related.
I prefer to see data transfer rate when moving/copying and so few apps support that

so is it a good or bad thing that the nexus has the same wifi chip as the galaxy s 2?

It's a no-go. Samsung/Google should have reinvented the wheel for the GN!
Seriously: If the GN didn't have the SGS2-wifi chip, it could be a better or a worse wifi chip, so it's neither a good nor a bad thing.

I have restarted my router and then retested the same operation in the same app on both: SGS2 and GN.
SGS2 was transfering at 1.6MB/sec, while GN at 1.2MB/sec. But at the same time I have tested CPU usage while transfer was ongoing and it was 20% at 520MHz, so that's nice.
But I did find out that other apps can transfer much quicker so its not that bad. It's just far from desktop PC speeds, at least as of now. Custom ROMs/kernels might improve things.
What apps do you guys use to transfer files wirelesly onto GN over WiFi? Any benchmarking done? Talking about files minimum 400MB in size.

Retested WiFi File Transfer app trat transfers files from desktop PC via browser, was getting ~2.8MB/sec. Galaxy Nexus, same WiFi network as previous tests. CPU usage while that transfer was in progress was 700-800MHz, 40-50%.

I use es file explorer and its very fast..

I usually prefer SwiftFTP for filetransfer and for direct video/audio streaming via DLNA "Skifta" (https://market.android.com/details?id=com.skifta.android.app).
Don't have my Nexus yet but worked pretty well on my old Milestone 2 so far.

can more people comment on the performance of WIFI on the GN? does it regularly drop its connection? is it as fast as your previous devices? etc. thank you

Mine doesn't drop at all. Seems to work just like SGS2 did.

The local file transfer speeds have absolutely nothing to do with your ISP's internet throughput speeds, it has everything to do with the type of your router, and the frequency you're connecting your device to.
If your router is 802.11g, the speeds will be capping in theory to 54mbps, in reality much, much lower.
If your router is 802.11n and you're connecting to 5Ghz access point, max theoretical speeds are over 300mbps when transferring files internally, again real world speeds are much slower due to interference, etc.
Also the actual flash memory in smartphones are not as speedy as solid state drives in computers so that's another bottleneck.
So firstly check the exact model of your router, google the spec sheet and start troubleshooting.

In my case the fastest speed I have seen so far was 3.2MB/sec, which is like 30Mbit. That was when uploading big file from desktop PC to my GN. This was on 2.4GHz n network with 40Mz band.

That's pretty much as high as you'll see on 2.4Ghz g network. Remember your flash storage has to keep up with all the file writing and it's far from being fast.
Safe to say you're seeing healthy transfer rates, mate.

Slow wifi file transfer

Hi,
I do all my downloading via LTE as I'm on an unlimited data plan and my connection speed is considerably higher than my fixed line internet but when I'm transferring the files to my pc via wifi, it seems abnormally slow. My files download at around 34MB/s (megabytes per second) but when I transfer them to my PC via wifi using cx file explorer (have also tried ES pro) I'm getting around 15MB/s. I'm using 5ghz AC wifi and the link speed in my phones wifi settings is 866mbps. Transferring the same files from my laptop to my PC via wifi is much faster at above 60MB/s.
Does anyone know what's going on here or have any ideas to figure it out?
Also, when transferring files via usb to the nvme drive in my laptop I'm getting 100MB/s, does this sound right? Was kinda expecting more from ufs 3.0.
(My usb cable is 3.1 gen2 10gbps)
Is something wrong here or am I just expecting too much from my phone? Any input will be very much appreciated.

Check to make sure that you aren't coming into any issues with wifi signal disruptions. Make sure your router is configured correctly.
Something's to try:
Choose a less congested wifi channel
Make sure you are using AES encryption
Select 40mhz or 80mhz channel bandwidth
Relocate the router to a different area
Restart the router
There is a lot of info on transfer speeds and etc, but suffice it to say a bunch of things come into play. If your running stock firmware then try getting a reliable class 10 microsd card for best read/write speeds. Keep in mind that microsd cards are rated for a max speed of up to X number (in mb/s). Sequential read/write, random read/write speeds will vary in speed.
MicroSD Cards write/read in megabytes per second, which is not the same as megabits per second of your wifi router (or USB 3.1 gigabits per second) speed. Internal storage is faster then microsd, I don't have the specs Infront of me right this second so I can't tell you by how much.
Also your wifi router does not give dedicated speeds per device, it has a set amount of speed that is shared amongst connected devices. More wifi devices connected transmitting/recieving data will cause speeds to decrease. Also the Wifi speed your seeing on the phone doesn't include any overhead from the router (or overheard from SMB/CIFS, etc), so your true speed may vary.
Try the router adjustments and see if that helps. If not then you may just have to live with what your getting speed wise for wifi transfers to/from PC.
* I will do some transfer tests with my wifi today and tomorrow to add more info on transfer speeds/setup. I am expecting a new wifi 6 capable router tomorrow, so I will post results of both of my routers after I get that set up...

Thanks for the reply,
My 5ghz wifi is running on 80mhz bandwidth, I've used inssider to check for other networks and there are none in my area running at 5ghz. My router is located in a space behind the sofa so I'm basically sat on top of it.
I recently installed the ASUSwrt-merlin firmware on my router (as well as the required full factory reset after the installation) but I've been experiencing the slow transfer speeds before and after installing that firmware. I have also tried putting my phone at the top of the QOS list in the router settings as well as turning QOS off completely.
I'm not using an SD card, all my files are being transferred from internal storage. I understand the difference between megabytes per second (MB/s) and megabits per second (mbps), USB 3.1 rev 2 is 10gbps, therefore has a throughput of 1250MB/s, obviously, you won't get that exact speed in the real world but you can expect a throughput of around 1GB/s providing both devices can handle that speed as well as the cable. I have done a storage speed test on my phone and the sequential read is over 1500MB/s and the write is over 500MB/s, well over what I'm actually getting over USB. I can deal with the USB speeds I'm getting, although it's slower than I expected (about 100MB/s), its fast enough for now.
If you could post the speeds you're getting, that would be great, If you're getting similar speeds then I know I'm just expecting too much from a mobile device (maybe Samsungs wifi module just isn't as powerful as a laptop one?). If not then I know I've got a bottleneck somewhere that needs fixing.
Thanks again for your input
EDIT: I have just read your edited post. Thanks for the thorough speed test, I guess I'm just expecting too much from my phone in comparison to my laptop.

I use wifi direct instead of es pro, es pro transfers much slower for me for some weird reason, Maybe it's something to do with the es or cx apps, have you tried wifi direct? I'll try cx file explorer a little later and post my speeds as well.
Edit: ok, cx file explorer took 20 minutes and 8 seconds to transfer a 918 MB file, a direct usb c 3.1 connection to my same laptop took 25 seconds for the same 918 MB file and wifi direct took about 45 seconds for the same 918 MB file. Sorry I dont have the speeds but it looks like it's something to do with the apps. Also have you tried using a cloud storage for transfers like dropbox or onedrive? It's may be faster.
Edit Edit: I also read that the usb cable that comes with the note 10+ only uses usb 2.0 speeds which is what I used.
