slow wi-fi ftp

why am I only getting 580kb/sec on my ftp transfers? I'm using mocha ftp server and on the pc I'm using Flashfxp...have I reached the microSD speed limit? Also, opera only gets around the same speed when using dsl reports with wifi.. pocket ie gets like 1400-1500kb.. and I've already messed with the wifi power settings..can someone help

I'd also like to add that when I use the usb connection and disable wifi I'm still able to ftp using active sync's IP...and still get around 500 BOTH ways.. I could swear that when I had a microSD card reader that I could xfer quicker, so I'm leaning against a read/write speed problem...

Wi-Fi LAN Transfer Speeds

I'd like to move video files from my Linux server to my Nexus 7. But I can't seem to get good transfer speeds. All transfers are over the LAN; no Internet hops involved.
Part 1:
I've tried using cafeFTP for SFTP and I consistently get speeds around 300 KB/s.
I've tried using AndSMB for Samba and I consistently get speeds around 400 KB/s (and Samba has file name issues).
I tried getting MTP to work, but it was really flaky; and I'd prefer a wireless solution.
My laptop (running Linux) transfers the same files via SFTP at up to 3 MB/s.
What kinds of speeds are people usually getting?
This is my first Android device so I have no other experience with Android transfer speeds.
Part 2
Best solution for transferring files from Linux to Nexus 7 without interacting with Linux machine (headless server)?
Also, does anyone have a solution that actually works to queue up a large transfer and keep trying until it's done? Both cafeFTP and AndSMB disconnect arbitrarily and then I have to reconnect and restart the transfers. This is incredibly inconvenient when trying to move a couple of movies overnight.
Misc. Info
My router is a WRT54GL running Tomato; I've been through its settings, but didn't find anything I thought would help.
I have done tons of searching about this; but there are so many garbage sites with no useful information covered in ads. I'm having a really hard time finding reputable information.
Thanks.

What sort of speeds do you get on a PC vs a PC?
EDIT: Blind.
What link speed are you getting in wireless info?

Showing 54 MB/s for both the laptop and the Nexus 7: Full 802.11g connection. Server is 100 MB/s.
Edit: I'm going to check the information when I get home to make sure I'm not idiotically mixing up bits and bytes...
Edit2: Checked info (updated original post for clarity):
SFTP: Laptop 802.11g transferring at 1.9 MB/s. Nexus 7 802.11g transferring at ~300KB/s

Isn't 800 KB/s pretty slow for an 802.11n connection?
My laptop transfers the same files at up to 3 MB/s over 802.11g (shouldn't you be getting like 3x that on 802.11n?) . But I'm only getting around 1/10th that on my Nexus 7.

Using FTP I get ~2MB/s. Strange

Well 800 kB/s is slow even for wireless G which should go 2.5-3 MB/s.
As for N these devices don't have 40 MHz channels so rather than 150 Mbps they are limited to 65 or 72 Mbps link rate, which should translate to about 3.5 MB/s

well i wonder what my problem is then. I have a netgear N300 and my win 7 drive is hardwired to it with ethernet.

I setup a plain FTP server which is getting transfer speeds of ~2100 KB/s. So that's MUCH better.
Perhaps the Nexus 7 just struggles with SFTP (encryption overhead makes this understandable) and Samba (not sure why it's so slow, just cause Samba is lame?).
Guess I'll be doing all my transfers over FTP. This makes me much less grumpy.
Just to recap, here are the transfer speeds I was seeing over 802.11g (54 Mbs connection) from a wired server running Linux:
SFTP: ~300 KB/s (cafeFTP)
Samba: ~400 KB/s (AndSMB)
FTP: ~2,100 KB/s (cafeFTP)
Edit: Current hypothesis is that SFTP and Samba were both maxing out the CPU. I haven't checked with a app to measure it, but the tablet did get hot during those transfers. If that's the case it may be implementation specific and other SFTP / Samba implementations may be more efficient and achieve higher speeds.

Using ES File Explorer and logging onto my windows share, I got file transfers of 700-900KB/sec, pretty poor.
So I set up an FTPServer on android and FileZilla on desktop and I get around 2.8MB/sec on transfers.

Sorry for resurrecting a year-old thread but I just wanted to thank you for the suggestion of using FTP as the transfer mode as opposed to Samba. It's definitely a bit faster (~700-850KB/s vs 1.5-1.7MB/s). I don't know why you installed FTPServer on your Nexus 7 though, since ES File Manager is an FTP client as well.

I have the same issue:
During copy/move large file i.e. 2-3GB from Nexus 10 to Qnap NAS with ES file explorer I get max. 2.5Mb/s .
Is that normal or pretty slow?
My access point is this one: TP-link tl-wa901nd

There's a big difference between an FTP server and an FTP client. if you use a client on Android, you need a server on your PC.

What's normal on your network is whatever is normal for your network. We wouldn't be able to tell you since there's so many factors that could affect speed. There is something you could use as a sort of measure though: Try a PC-to-NAS file transfer and check what kind of speeds you get there. It's not a scientific way to do it by no means but it should give you a rough estimate of the speed you should expect on transfers to your N10.

I have a Galaxy S4 with the newest firmware from samsung I9505XXUGNF1 (Kitkat 4.4.2). My router is a Asus RT-AC66U to which My S4 connects to with max speed of 433 Mbps. My internet connection is 120 Mbps.
When I do a speedtest on the S4 I get results of over 110 Mbps, but when I'm downloading a file over LAN from the disk connected directly to the router I get download speed only of ~20Mbps (2.4 MB/s) which is very sucky!
My Laptop have only a N network card, and connects to the router with max 300 Mbps and when I download the same file I get over 7.5 MB/s!! (~65 Mbps).
Speedtest also shows results of over 110 Mbps...
I remember when the phone was new, and it had Android 4.3, I had LAN download speed of over 9-10 MB/s...
I tried with different file managers like X-Plore and others, but it looks like it is not the app problem.

Have you tried transferring a file over FTP?

[Q] Wifi speed copying from windows share

Hi,
i cannot get over 4 MB/s (32 MBits) with my N10, I tried to copy from windows share and windows FTP on my local 1 Gbit network over 5 GHz (300Mbps connected) Wifi. When I do the same with 2 laptops I get 20+ MB/s.
I used total commander and ES file explorer...
Has anyone tested this ?

Seems fine here, on my 5ghz network. I normally transfer movies this way. Though I don't check the actual speed, I don't think it is lower than 4 MB/s. Sometimes I even 'stream' full movies just by opening the file on the network through ES File Explorer. Even with really high bitrate videos it does not stutter.

I would suggest changing the client. Try Astro or Solid Explorer.

Any way to improve android transfer/streaming speed?

Currently using my Shield TV as a media server for single user use. I have an external usb 3.0 hard drive connected. when transferring files via network from/to my pc, transfer rates are pretty low at around 5-10MBps, with frequent speed spikes during transfer, resulting in speed dropping all the way down to 0kbps, but then it goes back up again, but its not a steady average speed. If i were to do this between another networked device, speed is much faster and stable. Are there any settings or configuration files in android i could modify to improve speed?
I've got a possibly related issue with streaming as well. If i try to stream a long video, like a show or movie, stream initially takes what seems like forever to load, and jumping between scenes cause the pause again. I get that it has to buffer, but buffering seems to take forever for larger videos. This is most notable with Kodi, or other apps that stream video, and seems to be an issue whether the video is on the internet somewhere, or even on my local network. Youtube seems fine. though. Any way to improve this as well?
Everything is hardwired via gigabit connections

So if you plug another device into the same network cable and copy to the same external hard drive, you get better performance? Are you using SMB(Windows Shares) to copy files?
First thought is your network cable.
Second is SMB on Android SUCKS, though I have no issue streaming full spec HD over SMB in my current setup, but you won't get gigabit speeds on SMB with android and 5-10MBps is 40-80 mbps which is more than enough for streaming.
Try installing a speedtest app and see what it reports. Could help you identify if it's you network? SMB? or USB.

The intermittent speed issue seems to be the same whether transferring via ftp, webdav, smb, etc. im guessing its on the network but transferring to other devices other than android ( like to another pc for example) seems to not be affected, which is why im assuming the issue is something to do with the android device. its not my internet connection im talking about, but local connection on the local network. im using a netgear nighthawk r7000 router, with wired cat 5e cables on both the shield tv and pc.
the funny thing is my shield tv can even do gamestream in 4k, so i wouldnt think bandwidth is an issue, but streaming videos via software like mx player, kodi, etc seems to take awhile. like it isnt near instant, even at 720p/1080p. For example my external usb 3.0 hard drive is plugged into the shield tv, so the movies are on the drive. playing locally through the usb 3.0 works flawless, but streaming it to kodi on my pc takes a minute before it loads. dont get me wrong, once it plays, it plays and doesnt pause to buffer, etc. its that initial loading that seems to take forever. using the same 3.0 drive connected to my pc, streaming movie to shield tv running kodi, the issue is the same.
then when it comes to transferring, the same can be said with transfer speeds via usb 3.0 and ethernet. again, its all running on the local network, not via internet, so obviously theres some sort of network issue, but what? because when running via network on devices other than android the speed seems to all be there.

Similar situation here......also have an r7000
LAN network speed usually starts fast (50mb average), but gradually slows down to a somewhat stable 5mb
Are you using custom firmware for the router, or netgear stock firmware?
Theres an android app, that specifically tests network speed, search for "wifi speed test"

banderos101
Searching for wifi speed test in the play store results in several speed test apps but all ive seen seem to just want to test internet network? would need to test local network speed.
After more testing ive determined that the issue seems more obvious via ethernet. on wifi the connection seems more stable, steadying at around 5MBps, but eventually the connection slows and drops. On ethernet though, the connection is way more sporatic, bouncing continuously up and down, which is odd because obviously wired should be more stable. ive tried swapping ethernet cables and nothing seems to change the issue at all.
if only i could get 50mb average, id be happy, but im not even getting that. :\ when transferring locally on the shield, from the usb 3.0 external drive to the microsd slot or internal storage, speed is awesome at around 30-50MBps, so i know the capability is there, but its almost like the android network is somehow limiting performance. :/

Okay so after more digging I think I've gotten closer to the issue, now to just find a fix...
So after using WiFi speed test (which is great app to test LOCAL networks btw, thanks banderos101!) I notice that doing a TCP test is rather fast, averaging 50MBps on WiFi, even faster on Ethernet. However, the smb client tab for this app shows the same slow issue, and when you use it, it warns about slow speeds and suggest changing the "message block size" in settings to get faster speeds. So I do that and lo and behold, faster speed! The problem is the only thing I can find this setting for is in WiFi speed test app, and even a Google search seems to provide little information.
Does anyone know anything about message block size and how one could adjust it?

I'll give that app a try and see what I see, though I have no issues with local streaming.

Lan transfer really slow after nougat upgrade

I am trying to copy files through LAN using ES file explorer and it is painfully slow.
That said, my wifi appear to be fast enough (I get 54Mbps up/down which means, it should write at few MB/s)
Does not matter whether I am writing to the internal storage or external storage.
Not just ES file explorer, midnight commander also is having an issue.
I am wondering whether Nougat upgrade breaks SMB access/stack for some reason.
Can someone confirm/verify?

Just checked and downloads from my cloud account is not affected so it isn't my SD card speed issue nor the wifi issue (I get solid 3.5MB/sec download from cloud).
Just tried to copy the same file on my windows tablet and I can do solid 7-8MB/sec transfer so it isn't the source speed either.
I just can't pinpoint what the issue may be. I can swear that the speed was just fine prior to Nougat upgrade.
BTW, when I say "painfully slow", it is like 2-300KB/s speed.

I just read that same thing was happening with Galaxy Note 7 as well. Very slow access to SMB/CIFS.

I enabled FTP access to my NAS and it is now transferring at around 9MB/sec.
I wonder why the SMB/CIFS access is slow.
