WRT610N - slow wireless transfer betwen 2 Macs

I have 2 MacBook Pros running OS X 10.5.6, both connected on 5Ghz channel 36, 270 Mbps transmit rate, both Macs in the same room as the WRT610N.  When transferring files wirelessly between the Macs using AFP file sharing, it maxes out around 2.3 MBytes/s, which is about 19 Mbps, obviously nowhere near the 270 Mbps max link speed.  If I connect the 2 Macs using Ethernet, I can get 60-80MBytes/s transfer over AFP.
Is there some setting in the WRT610N config that needs to be modified to improve 802.11n transfer speeds?

pnikolsky, appreciate your response.  you're doing a transfer between a wireless client and a device connected directly to the router via gigabit ethernet.  i would assume that would be faster than transfers between 2 wireless clients.  however even 6 MByte/s seems slow for your setup.   i would expect your setup to get 12-16 MByte/s. 
also, based on 8 years of using various wireless routers (dlink, netgear, linksys), i know that changing beacon interval, dtim, thresholds, etc. has no major effect on transfer speeds.  you really only need to play with those settings if you're having connection problems to the router itself, which i'm not fortunately.
thanks for responding anyways.

  • Slow file transfer between Macs

    Hello,
    I am getting slow transfer speeds (<3 MByte/sec) while transfering files between Macs.
    Macbook Air 11" (late 2010) - Lion 10.7.4
    iMac 20" (2007) - Lion 10.7.4
    Airport Extreme (4th Gen)
    Wireless specs:
    Firmware 7.6.1
    WPA2 Personal
    2.4 Ghz on Channel 3 (no one near me is on this channel)
    5 Ghz on Channel 149 (I am the only one with 5 Ghz band on the neighborhood)
    AEBS, Air and iMac in separated rooms, with one wall between then (forming a triangle)
    Tested all channels; low, medium and high multicast; with and without wide channels; separated and unified 2.4 Ghz and 5 Ghz bands
    Average transmit rate at 2.4 Ghz on Air: 108-130
    Average transmit rate at 2.4 Ghz on iMac: 117-130
    Average transmit rate at 5 Ghz on Air: below 81
    Average transmit rate at 5 Ghz on Air: below 54
    Wirelss signal on both Air and iMac: maximum
    The files were all video files, ranging from 500Mb to 1.5Gb and the speed was measured using the Activity Monitor - Network Tab. The transfers were made through Finder by drag and drop method using shared folders, both Air to iMac and iMac to Air. The transfer was the only activity running on both computers.
    I know the wireless N is not supposed to work at 130 Mbps in real world (2.4 Ghz), but I was expecting at least 6-9 Mbytes/sec speed while transfering large files. (5 Ghz also tested but the transmit rate would never reach values above 100 Mbps and transfer speed was even worse).
    I have been reading a lot of topics in many forums but no tip was able to help me.
    Can someone give me a hint to solve this and at least double my transfers speed (6 Mbytes/sec)?
    Thanks.

    I just had some more important information...
    I was over at my inlaws house...on their wireless network receiving files works just fine. Something must be conflicting on the wireless network in the office.
    Any ideas of what it could be. I've tested several other macs there and they transfer files just fine over the network. But for some reason mine seems to have a problem.
    We have an SBS 2003 network and a linksys wireless g router.

  • Slow file transfer between Mac & PC Network - bad checksums?

    Howdy all. I've been having a persistent issue with transferring files from my Mac to my Win2003 server. The transfers are always much slower than they should be (compared to the PCs on the network with lesser connections), but even more puzzling, is that it will often go to 95% (or thereabouts) and then take twice as long to finish the remaining percentage as it did to transfer the vast majority of the file.
    It's all gigabit from point to point and I've swapped patch cables, router ports, etc.. with a known good performing WinXP box to see if that would make a difference, but it didn't.
    I've searched the forums and found some mention of mysteriously slow file transfers using SMB, but nothing conclusive.
    I ran a LAN monitoring util on the Mac during a xfer and below is a snippet of the results from the log. No dropped packets, but lots of bad checksums?
    Any help would be greatly appreciated.
    Thanks,

    While I have never tried it, Mac supports Firewire networking (TCP/IP over FW) and I know that some PCs do likewise. Mine does.
    That being said, it's possible to link your Mac to your PC with a FW cable (both ends must be the large type of connector) and if so, you can transfer at 400 MB/s.
    To enable FireWire networking on your Mac, in the Network preferences, at the bottom of the left pane, click the + sign and in the popup window, add Interface: Firewire.
    As I said, I have never used it but in theory it would work. It's not at all like using the Target mode, this is a "hot" FW network link that can directly connect two computers.
    IMO, it's worth a shot.

  • Slow wireless speeds on Mac Pro, but only downloads???

    I have an "early 2009" quad-core Mac Pro. I also have a Macbook Pro that's a couple of years old. I'm running speedtest.net, with the laptop sitting on top of the Pro. My wireless setup is a several-year-old Airport Extreme base station hard-wired to the Verizon router.
    My FiOS speed is 25/15, and that is generally what the laptop gets. When I first started this saga, the Mac Pro was getting about 4/12 on wireless (it is just as fast as the laptop if I hard-wire it). The laptop is also able to see about twice as many wireless networks as the Pro.
    I have had the Pro in to the Genius Bar 3 times over the last couple of weeks. I give them credit for trying really hard; they say it actually has better wireless speeds in their store than one of their own Mac Pros, so they are chasing a problem they can't reproduce. The main thing they have done so far is replace the Airport card, which improved my results to about 9/17, but here we seem to be stuck. At this point the store has done everything they can think of, and all they can offer is to give me the names of some Apple certified techs who can come out to my home office (for a fee, of course) and try to trouble-shoot it here.
    What I find most perplexing about this is that it's only download speed. I would think if there was some sort of interference, which is what they are thinking, it would affect both. And it would affect the laptop too.
    I have a brand-new Airport base station that I will try setting up, but I don't have high hopes. I can also try upgrading to Snow Leopard, but that is a big time sink that I'm not quite ready for yet (I like to do a full install when I upgrade).
    Does anyone have any other suggestions or tips on where else to research this?
    Thanks in advance!

    I saw this at a site where they were using DFS with Server 2003. When the few Mac's they had connected to the actual server and uploaded the file it was okay. But when it was sending the file via the \\DFS_node\share_name the Mac took heaps longer for the same file. Watching the Activity Monitor > Network monitor you could see gaps with the data transfer, as if there was some pausing between packets. A pcap showed that there was constant DNS requests coming from the Mac, even after the connection to the share was made. The same wasn't happening when the connection via SMB was directly to the actual file server. As there was only a few Mac on site they left it with the direct connection but were getting an MS specialist in to look at it. Never heard what happened with that one but you may want to try monitoring the packet transfer to see if the data movement is contstant or breaking. I'd also recommend getting Wireshark to monitor the transfer. You can compare upload to download and maybe even the transfer from the Mac to an MS workgroup share.

  • Slow wireless transfer (incoming files only)

    Hi,
    In our office we have 4 iMacs (Two CoreDuo & Two Core2Duo) & all are networked via our wi-fi router.
    One of the CoreDuo iMacs has a VERY slow transfer speed when anyone else sends files to it. EG: mount the iMac & drag files over to its desktop.
    This problem iMac has no issue in dropping files onto other peoples desktops, a speedy transfer as normal.
    An example of the slow speed: sending a 3MB PDF to the iMac takes about 25 seconds, compared to all the other iMacs taking less than 1 second.
    I connected this machine via Ethernet to the wireless router & the problem goes away. So, its only a problem with incoming wireless transfers.
    Any ideas how to start solving this issue?

    I seem to have had some success experimenting....
    In my network I see 2 folderss "My Network" & "Workgroup"
    In "My Network" all the other iMacs appear (& one appears twice)
    In "Workgroup" only 2 iMacs appear (the one with the problem does not)
    Now here is the interesting & slightly confusing part.
    Regardless of which network folder I use a particular machine will either connect via a CIFS/SAMBA dialogue window, or a ( & I presume its AFP) a Guest/Registered User style window.
    I noticed that if I get a CIFS connection, transfer is SLOW. If I get a AFP?connection, transfer is fast.
    I am able to recreate the problem now on the other computers if I get a CIFS connection.
    The thing is I cant work out how OS X decides to present a CIFS or AFP dialogue box - it seems random.

  • E3000 slower wireless transfer to USB vs. LAN

    My wireless transfers of large files to my Western Digital 2T (1021) drive run around 3.8 - 4.2 MB/s wirelessly.  On the LAN, I get between 7.2 - 8.5 MB/s.  I just upgraded to firmware 1.0.04.  These are the same speeds I got with fw v1.0.03 too. Here are my settings for my 5GHz wireless:
    Wireless Sec: WPA2 Personal
    Channel Width: 40MHz only
    Channel: 149 - 5.745GHz
    AP Location: Disabled
    Frame Burst: Enabled
    Basic Rate: Default
    Trans Rate: Auto
    N Trans Rate: Auto
    Trans Power: HIGH
    CTS Prot Mode: Disabled
    Beacon: 75
    DTIM: 1
    Frag Thresh: 2304
    RTS Thresh: 2304
    Am I doing something wrong here or is there a reason for the HALF speed transfer rates wirelessly?  Thanks for any help!

    bump, still no solution.  Linksys instant chat has been less than helpful.  
    So far, I've set everything back to default on the 1.0.04 firmware.  Reinstalled my wireless driver on my laptop to make sure I hadn't changed any settings.  So, as far as I can tell, everything is configured the same way, I'm just not getting the speeds I used to. :-(

  • Extremely slow wireless printing with HP Photosmart Premium C309g-m

    I'm seeing extremely slow print speeds when printing wirelessly from a Mac or a Windows XP system to a new HP Photosmart Premium C309g-m printer. The printer begins printing immediately when I request a print, but it only prints one line. It will then take about 15 minutes to print the rest of the page, printing each line after a very long pause. Demo page printing doesn't exhibit this problem, only documents from programs like Word 2008, Safari and Firefox (tried firefox on PC and Mac) are affected.
    If I connect to the printer through a USB connection it prints fine, so this problem appears to be with wireless printing only.
    Printer: HP Photosmart Premium C309g-m
    Computer: Mac mini (Late 2009 model) (also tried a Windows XP laptop as a comparison, using latest drivers from HP's website)
    OS: Mac OS X 10.6.2 with all available updates installed
    Computer connection method: Wired Ethernet connection to wireless router
    Printer drivers: version 2.2.1 (Apple supplied, HP drivers never installed as system shipped with 10.6)
    Wireless router: Apple TimeCapsule (Early 2009) 1TB, running in a/n and b/g modes on 2.4 and 5GHz. TimeCapsule is in bridging mode as the DSL modem handles DHCP service
    Encryption: WPA2 Personal, no MAC filtering or hiding of the SSID.
    IP addressing scheme: All addresses are handed out by DHCP server with no reservations of any kind
    The TimeCapsule is sitting three inches from the printer and the printer indicates full signal. Connection of the printer to the wireless network and setup of the printer on the Mac went without a hitch. Only when printing a test document did we discover the problem. The wireless network is behaving as expected when accessing the Internet from both Mac and Windows devices (tested with a Dell laptop running XP and a MacBook running OS X 10.6.2), so I don't see any overall problems with the wireless network.
    Attempted remedies:
    1. Rebooting and powering off, waiting, powering on computer
    2. Resetting the print subsystem, turning the printer off and on again and reinstalling the printer
    3. Unplugging power from the printer and letting it sit for several minutes before trying to print wirelessly.
    None of these worked.
    This question was solved.
    View Solution.

    I don't think there is anything wrong with the DSL modem HW.  There might be an issue with how print data is being routed though.
    Please try the second experiment where you blank-out the default gateway and DNS entries from the printer's internal web configuration page.  Open the printer's internal web page by browsing to its IP address.  Select Networking and then Wireless (802.11).  Under the IPv4 Configuration tab, select Manual IP:
    For Manual IP Address, use the existing printer IP address.
    For Manual Subnet Mask, use 255.255.255.0
    For Manual Default Gateway, leave blank.  This is important.
    Select Manual DNS Server:
    Leave both the Manual Preferred DNS Server and Manual Alternate DNS Server fields empty.  This is important.
    Press Apply.
    Turn off the DSL modem, the printer and all computers connected to your network.  Wait 60 seconds then turn on the DSL modem and then turn on the printer.  Then turn on the computers.  See if this corrects the printing speed.

  • One Solution for Fixing Slow Wireless Connection

    Quick and easy solution for slow wireless connection.
    My hardwired PC connection was working fine over FIOS, but my wireless connection through my Macbook Pro was soooo slowwww, although the machine itself was fine. Pages would take forever to appear, then finally sort of pop up. Didn't really seem to be a Mac problem, just a connection problem.
    After searching forever to find a fix, I found a quick & easy solution that works at least for now: change your DNS address. 
    I'm not a techie so I don't know ALL of the implications of doing this, but in desperation, it has worked for me and I think at no risk to your network or machine. Changing my DNS address has made my connection blazing fast and relieved many weeks of frustration. 
    HOW: I can only share how to change on a Mac. (Please chime in if you can give directions for PC. ) Just go to this Apple support page, which will outline exactly how to do it. I used 4.2.2.2, I think you can also use 4.2.2.1 as the DNS address. http://support.apple.com/kb/TS2002
    Other resources I've found follow:
    (specific to FIOS):  http://www.stationstops.com/2008/04/16/high-speed-internet-3-tips-to-optimize-your-verizon-fios-broa...
    (Specific for Mac): http://forums.macrumors.com/showthread.php?t=358919
    Maybe this is a commonly-known fix but it wasn't for me, so hopefully it will help some of the other less-than-technical people out there. Good luck! 

    Actually this is a common problem with Mac OSX (http://rubyisbeautiful.com/2008/2/8/osx-dns-fix-update) and how it does DNS lookups and pertains to routers that provide the internal gateway (i.e. 192.168.1.1) as the DNS address which is what the ActionTec does by default.
    You can change that at the router level to either push out Verizon's dns that the router then uses or any other open dns server.  I had to do this a long time ago for some of the OS X boxes on my network.

  • Slow wireless speed with new iMac Intel- problem with 802.11g?

    There IS a problem with the new Intel Mac, I have tried both the Intel iMac and the new Intel Mac mini and they both have the same problem with slow wireless speed (or rather it variates, if I do a ping to another computer on the network the speed goes from < 1 ms up to 1000 ms and then down to < 1 ms and so on). The older mac minis, my Linux boxes and my Windows PCs don´t have that problem. I have also read reports on the net and it appears that most users experiencing this problem have wireless card firmware version 101.3 (3.120.28.3) . A possible "fix" is to change to 802.11b on the router and then it works. No speed fluctuations and a stabile network! I know it is a bad solution, I would prefer to use 802.11g and get the speed. However I think this points to a problem with the drivers regarding 802.11g. I am starting up a new thread on this and those of you with problems, please try to switch to 802.11b and if it works let us make Apple aware of this.

  • Slow file transfer - ethernet + firewire issue?

    Here's the setup -
    Win98PC > ethernet (direct cable connection) > iMac G5 > Lacie d2 FW drive
    Connection (100BaseT) works, logins work fine, browsing folders & files is fine. But when I transfer files from the WinPC to the Lacie drive through the iMac G5 it is unbelievably slow. Same thing if I use one of my other Macs in place of the WinPC, so it looks like a network or iMacG5 issue, not a WinPC issue.
    On the other hand, if I use Airport to connect a WinPC, eMac or MacBook to the iMacG5, the file transfers are blindingly fast.
    Is this perhaps because the FW & ethernet controllers in the iMac G5 are the same PHY chip? Is this some kind of contention for bandwidth through the PHY chip? (The Airport card in the iMacG5 is on a separate bus, not connected to the Ethernet/FW PHY chip, which makes me suspect something is up with the ethernet/FW controller.)
    Anyone else encounter a problem like this with slow file transfer through your iMacG5 to an external FW drive?

    Martin, that's really interesting. I've noticed slow network transfers in the past but always racked it up to overhead and parity errors inherent in the OS's. Never thought it might be the PHY chip, though it certainly could be. Apple has a broadband tuner which might help you by increasing packet size (but you probably knew that as a Level3). My stopgap is to do the file transfers with firewire, but your laptop may not have that option.
    You could maybe copy to the mac over the network, then copy a second time to the LaCie. Not elegant or clean, but will save you time. Kinda like taking the backroads to avoid rush hour traffic - it's farther to go but you get there faster.
    I'll look into the controller question. Let us know how you're doing,

  • Slow Wireless Internet (BT homehub)

    Hello, I have a problem with slow, wireless internet with the BT Broadband Homehub 2 (black). I am using a 1g Macbook 2 running 10.4.11.
    A quick summary of my problem: Recently, there was a fault on my line that was affecting my phone and my broadband. BT quickly repaired the fault and reset the broadband as I complained about the speed. Connection monitors and speed tests all say that everything is running fine although I Firefox and Safari are loading pages extremely slowly; streaming of media is impossible and it sometimes times out before I can even send webmail. When I first got the connection it was lightning fast (so much so that friends commented on it when they came over). I have see that lots of people seem to be having this problem with Macbooks and I am 99.9% certain that the issue is a mac software/hardware issue. I have tried EVERYTHING that has been suggested in other threads
    1.I have manually entered different recommended DNS figures
    2. I have changed the wireless channels
    3. I have manually entered the DNS figures supplied by the ISP
    4. I have rebooted with default settings
    Nothing seems to work. I'm a little bit out of my depth with this sort of thing but I have noticed that the IP address supplied by my router to airport settings doesn't correspond with the IP address in the
    ISP info. I tried changing that but then I couldn't connect at all. Somebody must know what is going on here as I've seen this problem quoted on this and other forums. Is it a problem that apple are aware of? Somebody please help as this is very very frustrating.
    Thanks everyone.

    Hi Jocksil, and a warm welcome to the forums!
    BDAqua, what does you psot mean?
    No idea if it worked for the OP, some never return to tell us what happened.
    My suggestion should speed up a lot of connections, and never hurt anything, but not sure what the mentioned problem was, but my suggestion won't likely help connecting in the first place, unless it really is connecting, not just getting anywhere once connected.
    DNS Servers are a bit like Phone books where you look up a name and it gives you the phone number, in our case, you put in apple.com and it comes back with 17.254.3.183 behind the scenes.

  • File Sharing Problem and slow data transfer

    Hi,
    i just receive my MBP a few weeks ago and i wanted to transfer some data with a friend who has a MacBook. I tried to share a folder and it cold not be seen by the MB as guest login. i checked the permission when i add the folder to the file sharing as read only. Second problem i had is more intriguing...finally a i decide to log in as Me with the MB, and then i saw my folder shared. he copy the stuff he need it with an acceptable speed. He shared a folder to me the same way i tried and it works!! but the more frustrating was to see how slow was the transfer from the MB to my MBP. Can find any explication...any suggestion???? please !!

    slowness of wireless transfer speeds could have something to do with your access point/wireless router.... if you have bad bars on your airport card then try moving closer to the signal.
    also what is that total size of the files you are trying to move to each laptop?
    i remember when i transferred a fair amount of MP3's it did take a little bit of time....

  • HT201364 What is the change betwen mac book late 2006 and mid 2007 ?

    What is the change betwen mac book late 2006 and mid 2007 that couses the OS X Mavericks not to run on it?

    Neither the 2006 or 2007 MacBooks will run Mavericks, nor will the white plastic cased 2008 models. The oldest MacBook that will run Mavericks is the Aluminum case Late 2008 one.
    Looking at the specs, I think that is because prior to the aluminum 2008 model, all MacBooks used less powerful Intel Graphics Media Accelerator (GMA) graphics processors with (at most) 160 MB of available video memory. AFAIK, neither Intel nor Apple ever released 64 bit drivers for these GMA graphics processors, so when OS X dropped support for booting into 32 bit mode in Mountain Lion (OS X 10.8) that meant the newest OS these MacBooks could support was Leopard (OS X 10.7), the last version to support 32 bit mode.
    It is also likely that the GMA's, with their limited memory & support for parallel processing, can't effectively support technologies like Grand Central Dispatch that system services in the newer OS versions increasingly rely on to speed up more than graphics rendering.
    So, even if one could find a 64 bit driver for the GMA's, the system probably would be too slow at too many things to be practical. (Personally, I have a while 2008 MacBook, & I think the "best fit" OS for it is Snow Leopard. As far as I'm concerned, Lion is basically a beta version of Mountain Lion with too many rough edges & limited user choice to run on mine.)
