Slow File Transfer Over Wireless Network
Apr 22, 2012
I have a wireless network with 2 desktop hooked up wired, and one laptop that's wireless. Accessing files on the desktop with xp installed is quick and transfers files at around 5-7mb/s. When I connect to my main pc with windows 7 on it, file transfer is EXTREMELY slow and almost always stutters and freezes. I've tried removing the drive from 'shared' and then adding it again, reinstalling my ethernet driver, swapping ethernet ports on the back of my router, and resetting it altogether. Still a slow transfer speed.I use workgroup all around, for xp and for 7.

I have recently purchased a Cisco E4200 to replace my D-LINK DIR-655, which I thought was defective because I was getting slow wirless file transfer speed, regardless of setting, location and client.Using the E4200, when I transfer a file from a PC to another, both connected at 300mb on the 2.4ghz band, the file transfer rate reported by windows 7 and networx is from 2MB/s to 3.5MB/s. I think those transfer rates are not acceptable. Is that a good assumption ? I would expect something in the range of 10MB/s (which is what I get with a cheap dlink router, wired)
I also had great difficulty finding a channel. I had to try them all one-by-one as the auto channel selection made my PCs connect at 130mb.The E4200 is setup as follows:
-WPA-Personal
-Channel 5
-802.11n only
I have tried 3 different computers with different network adapters and they all underperform (IMO..).There are no other wireless networks in my area.I also took the E4200 to my office which is very crowed. Every single channel is occupied by several wireless networks. I get a file transfer speed PC to PC of about 2MB.I basically could have kept my DIR-655 as the speeds are identical.

I am having incredibly slow connection while transferring files using file sharing.I have the below hardware:
108Mbps TPLINK Wireless Router
TL-WR642G 108Mbps TPLINK Wireless Access Point acting as repeater
Laptops accessing internet and folder sharing enabled for local file transfer
Transfering of files excessively slow (after playing around with the settings was able to get 500KBps). I have set all wireless adapters on the laptops to 802.11g only.Tried setting the router and access point to both 54Mbps and 108Mbps 802.11G only as well as b/g.

1 newer build computer connected to D-link 655 via Cat6.1 laptop computer connected to same D-link 655 via Wireless N minicard. (Intel) (130Mbps connected) Router on a 10 foot shelf, always have full bar in wireless strength on 2nd computer.
Both computers can upload and download as expected from the internet. Transfers between the two computers though are slow. Both computers are loaded with Windows 7. Transferring files to or from the laptop transfers at 1.5MB/sec to 2 MB/sec.

I have two machines that both have WUSB600N wireless network adaptors with a Cisco WRT160N router. The file transfer speeds between the two devices maxes out at 1.6Mbs. If I run speed tests off the internet I hit 15 to 20 and downloads are excellent. I have played with all kinds of settings for the driver and router but nothing seems to work. Both these devices are running Windows 7. I tried a file transfer with an XP device as well and it maxes at about 1.6. how to increase the bandwidth??

I have a RV220W operating in 2.4GHz N-only mode. Channel bandwidth is set to 20MHz, channel to 6 (a site survey shows that channel as completely clear), WPA2/AES. I am connected to a TrendNet wireless bridge. The admin page for that wireless bridge shows a link quality of 100% with a signal strength of 71%. If I select a higher channel (11), the signal strength drops to 51%.
I have a Windows 7 PC connected to the Trendnet bridge and a Windows 7 server connected to the RV220W, both via a 1Gbps LAN port. When I transfer a file from the server to the PC or vice versa, I get a lowsy 2MBps (~20Mbps) transfer rate. That seems awfully slow. I tried channel bonding from 20 to 40 MHz

i am running windows server 2008 with the hyper V role installed.i have installed windows 7 Professional as a guest OS. assigned 2 GB of Ram to the machine. the point behind the VM is to virtualize my FTP server and incase a format is required i have the VM file on my 2nd partition, host OS on another. i use Cerberus FTP Server on the Win7 OS. i configured the server to accept SFTP and TLS connections. on the host OS i installed Fire FTP and File Zilla, both Clients will at max download a 4 MB file at 64 KB/Sec .. i have seen both jump to about 80 KB but was only a split second and never held.. however if i login without SFTP and transfer over standard protocol, i download at 1 MB/sec. which is my normal speeds. would this be only to the encryption process?, in the Cerberus Server there are options to adjust download speeds, i have left it default, and altered it to allow its max configuration. My ISP is not limiting any connections that shouldnt be.

I recently switched from an older 10/100 linksys to this gigabit router from D-Link. However, when I try to transfer files from one computer to another on the LAN, the file transfers are ridiculously low, right around 16KB/s. I have CAT6 cable for all connections, but am baffled by what could cause such a slow speed. I'm trying to transfer files from my desktop (win7) to my server (Windows Home Server 2011).

I am getting very slow window file transfer speed (4 Mbps per second) between two connecting servers in Cisco 6509 switch. I have connect the two laptops in 6509 switch in same module using the same vlan and try to copy the files from one laptop to another and vice versa and got the same speed on 4 to 5 Mbps per second. Switch utilization is not more than 10% and both the laptops are connected in 1 Gbps full duplex.
I have checked by removing the gateway in both laptop but the output is same.

I am noticing the following issue with one of our VPN connections:
Site A is connected to the Internet with an ISA Firewall
Site B is connected to the Internet with a CISCO 5505
Both sites are connected together via a VPN ,Both sites have around a 6MB up and 6MB down connection to the Internet
If I sent a 100MB file from Site A to B it takes around 30-45 minutes to copy, which to me seems excessive.
I've run Wireshark on the server sending the file (from Site A) and the desktop receiving the file (Site B). Initially, the server sending the file was generating a large number of TCP DUP ACK, TCP FAST RETRANSMISSION, TCP PREVIOUS SEGMENT LOST AND TCP OUT-OF-ORDER messages. I narrowed it down to IPv4 Checksum Offload and IPv4 Large Send offload which I disabled on the server. This sped up the file copy and massively reduced the errors in Wireshark, but not to what I think it should be. I then performed Wireshark logging on the desktop receiving the file which was also generating a large amount of TCP DUP ACK, TCP FAST RETRANSMISSION, TCP PREVIOUS SEGMENT LOST AND TCP OUT-OF-ORDER messages. I disabled IPv4 Checksum Offload and IPv4 Large Send offload options on the network card of the desktop and tried resending the file, which made no difference in speed and still generated the above messages in Wireshark.
I have run an mturoute between site A and B and get the following:
C: emp>mturoute.exe 10.0.66.2 (to PC on site B)
* ICMP Fragmentation is not permitted. *
* Speed optimization is enabled. *
* Maximum payload is 10000 bytes. *

url...I have 2 PC's connected to a DIR-615 through 802.11n and each have a DWA-130 802.11n adapter. I am running Windows 7 Ultimate 64 bit on both computers. The specs of both systems are very high.I only have these 2 computers on wireless right now. Their signal is full strength, they are less than 10 feet away from the router.I am getting 2.0 MB/s when transferring files between them and although I am not expecting to get 17MB/s, but I should be getting better speed than 2 MB/s.Hard drive specs are Crucial C300 SATA 6.0, WD Caviar Blue SATA 3.0, and WD Caviar Green SATA 3.0. My Green drive reads/writes at 100MB/s, My Blue 125MB/s, and My SSD 225MB/s. So, those are not the bottleneck.Is there any other settings I can try? I have not messed with my DWA-130 settings nor have I messed with Windows.

I'm having very slow file transfer speeds between the 2 computers on my network. One is a gigabit pc wired (cat6) to the e3000. The other is a wireless N laptop. Both computers running Win7. Speeds are like 1.5 - 2 MB/s. when I connect the laptop to the router with a cable (cat6) I get proper high speed. Trying to figure out if it's a problem with the router or windows or what. Speedtest.net says I'm getting 16 MB/s DL wirelessly to my laptop. Shouldn't wireless N be capable of higher speeds than 1.5 MB/s?? Tests are done approx 10 feet from the router.

I have been trying to get this setup for 2 days now and so far NADA.....
Router: Linksys E3000 - below is a list of all devices connected (hardwired T568B) to the 4 ports with a laptop connected via wireless
1. Main PC - motherboard: ASUS Maximus IV Extreme-Z (dual GB LAN ports)
2. Media Server - motherboard: MSI Z68A-GD80 (dual GB LAN ports)
3. Test Bench AMD PC
4. WD TV Live
Currently: I have all 3 computers running Windows 7 and connected to a Homegroup. I have given the correct permissions to enable sharing of files between each of the 3 computers and can transfer files from one PC to the next w/o any issues.
Desired: I want to connect my Main PC and Media Sever with a crossover cable using the 2nd LAN port on each motherboard, so that I don't have to go through the router to transfer data to and from these 2 PCs. I will have each PC also connected to the Linksys E3000 router via the 1st LAN port on each motherboard to supply the internet connection, so I am also not trying to "share" an internet connection between these 2 PCs. Basically, I want to run my home network through the Linksys E3000 and then a 2nd network for the 2 PCs using the crossover cable.
Current Problem: I disconnected the straight-through cables from the router to each computer from the 1st LAN port. I then connected the crossover cable from the Main PC to the Media Server and setup a new Home network in the Network and Sharing Center in Windows 7. Everything worked and I could transfer data to and from each these 2 PCs, so i know I wired the crossover cable correctly. Then I reconnected the straight-through cables coming from the router to the 1st LAN ports of each mobo, thinking that each PC would auto-detect the internet connection and reacquire my existing home network, enabling an internet connection again. However, this did not happen.
[URL] I also followed this how-to guide on microsoft.com, but when I get to Step 3 where it says that an "Unidentified network icon" will aprear in the Network and Sharing Center, it does not!
From Googling, reading, and troubleshooting I believe I know 2 things:
1. All of the hardware is functioning properly - when the straight-through cables from the router are disconnected, the 2 PCs are networked through the crossover cable and files can be transferred.
2. The problem is with Windows 7 somewhere - I think?

2-Desktop PCs
2-Qualcomm Atheros AR938x wireless cards, both connected on 5Ghz network at 450 Mbps.Router-E4200, latest firmware, the only 5Ghz network in the area
One PC has a drive bender drive pool on it that I'm trying to read/write from. Testing the pool w/ crystal disk mark on the local pc shows fast speeds (650 MB/s read, 67 MB/s write), so I drive bottlenecks aren't the issue.
Connecting at 450 Mbps i would expect to see something like at least 200 Mbps actual speeds, or is this off? Using LAN Speed test I'm getting 41 write and 52 read. Not great

My work has a main office and a backup office which is off site. What I am trying to do is copy a folder from one computer at the backup site to another computer at the backup site, all while sitting at my computer in the main office. Let's say the two computers at the backup site are called comp1 and comp2.Whether I use Windows Explorer, or .net VB script, or XCOPY from the command prompt, if I try to copy \comp1c_drivefolder to \comp2c_drivefolder from my computer then it takes an extremely long time - around 5 hours for 2Gb of data.
However, if I Remote Desktop into comp1, and from that machine copy C:folder to \comp2c_drivefolder then it only takes 5 minutesI can only assume that when I try to copy the folder from my computer remotely that it is transferring the data from comp1 -> my computer -> comp2, and with the computers being at different sites it's very slow. What I need to know is if I can do this remote copy using VB without the data going via my computer, i.e. straight from \comp1 to \comp2.
I thought this was the way Windows handled copying between networks anyway, i.e. straight from one to the other, my only explanation for the terrible speed is that it is going via my computer. I'm writing a basic folder-backup program in VB and would REALLY like to cut that 5 hour transfer time down to the 5 minutes I know the network can do

I spoke with two different support agents with a well respected routermanufacturer. I got two different answers - No surprise.So, I ask the forum, what file transfer speeds should I expect when transfering a good sized amount of data (10gig) from wired PC on a 10/100/1000 network router to another PC via wireless connection 20 (feet away + two walls) using 802.11N.Both PC's are new / newer with win 7 64 bit. - Current transfer speeds - Both wired and wireless internet download speed tests are arond 21 meg per second. Both PC's wired and wireless get around 3.7 meg per second internet download (speed tests).At this point - no real difference in internet access between PC's and wired / wireless.
However, when I copy a file from PC1 to PC 2 (both wired) I get 68 megs per second. When I transfer the same data set (10 gig) from PC1 wired to PC 2 wireless, the data transfer falls to 3.7 meg per second. One rep told me to expect about 80% of my wired rate or about 54 megs per second (when using my 802.11N 300meg) equipment. The other rep (same company) told me that the 3.7 meg per second ia about the best I can expect. A transfer rate of 3.7 megs per second simply does not appear to be a reasonable speed given that all my wireless equipment is pretty new and supports numbers that are much higher

Hardware Software profile;
Laptop - Windows 7
Desktop - Vista Ultimate SP2
Router - Cisco Linksys E3200
Cables - CAT6
I am a sales engineer, so I use my desktop and laptop all the time. When on road, I sync my desktop with my laptop using a program called ViceVersa. This a very good, reliable syncing program that I have been using for over 10 years ( with upgrades ).
The program allows me to sync my desktop and laptop. The program also shows the data transfer rate during the syncing process. The typical data transfer speed is between 5MB/s and 10MB/s with sometimes up to 12MB/s. A typical sync between the computers will take about 3 - 5 minutes at the ~ 10 MB/s transfer rate using ethernet CAT6 cable inteface. At about 11pm last Tuesday,there was a Windows update on both my Vist and Win7 computers. On wednesday, I went to do a typical sync. The system has dramatically slowed to 59KB/s max. This is about 150 times slower than 5-10MB/s that I was used to for so many years. My typical sync was now taking about 2 hours....unacceptable ! I have tried everything to figure out what is going on and how to fix it but nothing has worked.
Then I tried to see what would happen if I disconnected my ethernet cable ( between the router and the laptop only ) and just sync using the wireless network. With that configuration, the transfer rate is ~ 2.5 MB/s which is not great but is much, much better than 59KB/s. I actually do not know what a reasonable wireless transfer rate should be since I never really did it before due to the faster speed of the wired configuration.
This is just a LAN. Only connecting my Desktop to my Laptop via the Cisco router.
How I can get my wired configuration back up to the 5-10MB/s transfer rate that it once was?

My XBOX started complaining when I began using Windows Media Center to stream videos from my PC to my XBOX. I found out that I had a wireless G router provided by verizon which wasn't fast enough to stream videos. SO, I went out and purchased a 4500EA router expecting it to be the fastest thing I had ever seen.
Now it seems a bit slow when trying to stream video from my laptop to the XBOX and i'm a tad bit confused as to why. So I did a file transfer from a desktop wired directly to the router from a laptop in the same room wirelessly connected to the network and my speed is about 4mbps. 4MBPS!? This device is supposed to be capable of moving packets LAN side at 450MBPS.
Both of my PC's are quad core, newer model PCs. I've tried moving files now for several hours with the same results. I've toyed around with my wireless adapters, changed power settings, full duplex, half, changed mtu sizes, changed security settings. I'm out of ideas.
Is getting about 1% of the advertised bandwidth normal?

This is another E3000 "connection drops" thread. Some background: I have two E3000's that are cascaded. The main router is in my basement connected to my cable modem and is my DHCP server. The second one is on the main floor and provides my wireless signal (no DHCP, and is hard connected to the main router).I have lots of connection drops with the wireless router on the main floor. Lately I have noticed a trend, though. My connection drops mostly when I browse my network (usually browsing pictures on another computer) or when large files or videos are being transferred. If I connect a cable, I have no problems. When wireless, I have signal drops.I have tried every trick and tip that I've seen on this forum or been provided in the Linksys FAQ. I've changed the beacon interval, fragmentation threshold to 2306 and CTS to 2307, I've tried changing channels, I've checked and unchecked boxes for NAT, Filters, etc. I've tried different combinations of WPA2 passwords. I've tried dynamic routing, static routing, blah blah blah...
When I set the 5Ghz channel to Auto(DFS) it defaults to channel 36 and 144Mbps. When I use other channels, I get 300Mbps. Either way, my connections still drops.
I have the latest firmware 1.0.04 Build 6.I even have the router sitting on top of a laptop cooling pad to keep it cool.No matter what I do, as soon as I start browsing my network the wireless connection drops.I am so frustrated! I upgraded my WRT-160N to this E-300 router to get the faster speed and dual band but have had nothing but trouble. I never had a connection drop with my 160N.
EDIT: I notice that when my signal drops, I can see the power LED blinking on the router, like it's going through a reboot cycle.

Having got a new Windows 7 (64 bit Ultimate) PC, I decided to turn my old PC (XP Pro) into a file server. After much fun with Windows networking, I have one particular problem. Listing files on the server from the Win7 machine is ridiculously slow. A few directories have large numbers of files in them, around 10,000 image files. Browsing to one such folder on Win7, I have timed a listing and it took 48 seconds! That's a very long time to wait for a file listing. I have a network connection monitor running and it doesn't seem to be overloading the network- data was dribbling down the 100Base-T cable at about 200kiloBITS per second. Trying things the other way around, the same folder if placed on the Win7 machine and listed from the old XP machine can deliver a complete listing in about 5 seconds. I'm not sure which end has the problem; either the server is delivering file names very slowly or (my guess) the Win 7 machine is asking for them very slowly, perhaps asking for lots of crap that isn't needed like icons or file dimensions or something.
