Sharing :: Lot Of Limitations To Huge Transfers - Low Speed?
Feb 22, 2011
I recently got a Static IP from my service provider, I'm working from home & configured a FTP server in my PC.
I have to transfer huge files say around 40 GB of data as I'm a Multimedia professional. I was using my web server, before for file transfers but there are lot of limitations to huge transfers.
My client, who is downloading using my Local Server says, it takes 3 mins to download a 9 Mb file, which took 17 sec before, when it was done with the webserver.
Does this have anything to do with my Internet connection speed as my speed is 1 - 2 Mbps. If not is there a possibility to increase my transfer speed ?
I'm using a CAT5e cable. But it gives only a 10 MB/s file sharing speed. What is the reason for this? (In both the computers under "Local Area Connection Status" it shows 100 Mbps for the speed)
Can I have two wireless networks running in the house? Does a low internet speed affects my home network sharing capabilities? Can I have one network with internet and the other one just intranet. I would like to stream using DLNA without affecting my internet speed. I have D-link router DGL-4500 and another router Cisco Linksys E1000 new in a box.The internet provider in my area only provides up to 750KBps. I have a large number of internet enable wireless devices and most of the time the connections is not even fast enoguh to even stream youtube video
i have the linksys wag200g with firmeare 1.01.09 and i have connected on it one desktop - laptop - netbook and if i download to any of these pc one and only file with the maximun download speed of my line(1.300kbps) and i send one file from one pc to another share folder one of these two files it is tooooo slow and In no situation doesn't both reach the maximun speed.
I have two ASUS UL80 laptops and trying to copy files from one to another. I also have a Linksys router with WiFI on.
The speed of a file transfer via router + LAN cable (or only the LAN cable) is about 600KB/s. I tried to turn off firewalls on both PC's, but it increases the speed by only 100KB/s.
You would think that's easily found via Google but that is not the case Our firewall seems to be blocking some file transfers from wireless clients logged into the domain to our Server 03 file server so I need to make an exception but I don't know what port is actually used for that.
Netgear Wireless Bridge connects to my long term hotel's wifi, and feeds via ethernet into the Internet port of my WNDR4000.WNDR4000 has my Desktop and WHS connected via gigabit, while the HTPC is 450mbps wireless N with an Intel 6300n, and my Macbook air is connected via 5ghz wireless n as well.I'm having a very bizarre issue where all large file transfers - even over gigabit - are corrupted, while direct downloads are not. I've been pulling my hair out trying to figure out why I CANNOT make a working windows install disc from a tech net iso, and eventually starting checking sha1 hashes. This is how I discovered that direct downloads to machine's hash correctly, but if I transfer it to another machine the sha1 is completely different.
For example, if I download the iso on my macbook air and transfer it to my WHS, the hash is correct on the MAcbook but on the WHS it fails. If I download it to my desktop and transfer it to the HTPC or WHS, same thing happens. There errors are bad enough that Windows setup errors out with a corrupt file error if I make the disc from a networked machine. I have to use the local file to get it to work.
This has been a problem for quite a while now, jumping from Shaw to Telus,I have completely exhausted, and I have no idea what's wrong.I live in a household with another family, and we share internet connections, Telus Fiber Optik, as of now. Me and my brother both have our own computer and are connected via wireless adapter, and the other family has one laptop with wireless connection.
The problem would be that randomly, the internet would slow down considerably, with pings going insanely high, like over 9000ms (not joking).At first,I thought I was just too far away from the router.So I moved to a room directly under the router, and the internet was completely fine for around 1 week, then the random ping spikes started to happen again. Now, I've tried tweaking wireless settings, and checking to make sure its just not my wireless adapter, however my brother's adapter is new, but it has the same problem too, so I doubt its the adapters fault.
I have a couple of pc's between which I transfer video files using Wifi, one is a laptop running XP and the other is a media centre which *was* running Windows 7. The laptop is connected to an N router using an ethernet cable to increase speed and because they are located next to each other, and the media center which is on another floor of the house uses a Wifi connection to the router.
The file transfers between the pc's used to run at about 70Mbits/sec which I was happy with. However due to problems with the media centre, I recently downgraded that pc to XP since I get much smoother HD video playback from XP MCE. But... since these changes the transfer speed has now halved to about 35 Mbits! Remember all the pc and network hardware is the same, the only change is to the operating system on the media centre pc.
At first I though maybe the different XP drivers for the network card on the media centre might be rubbish, so I changed the network card altogether, but the speed has remained the same. I have also stripped the networking configurations down to the minimum to reduce overheads, so have removed QOS and unnecessary file and print sharing etc. But none of this has worked. Am I missing something in the XP network configuration that might correct this problem, or is it simply the case that Windows 7 Wifi is just that much improved and faster than XP?
I'm having constant lag spikes. I use DPC Latency checker [URL]On both my desktop (using PCI wifi card) and my laptop I have lag spikes. This is a screenshot of the spikes [URL]. Although it says its my hardware problems, I doubt its true, as it happens on both devices.
I have a WRT54G v6 router and I am trying to get higher speeds from a wireless network, I have set up a dish and a cantenna and is going really well about 18-22dbi gain which is very noticeable but I have a question, does an ?Ethernet cable speeds up the transfers Like the Upload and download speeds will be faster? like a high speed cat7 or cat6 cable that can transfer data at much higher frequencies? I have cat 5 and get around 13Mbps, will cat 6 get me 16 or 17? or the router can't handle it?.Also another question is how can I make the gain on the dish higher?
I am using csc-ssm module in Cisco ASA 5520 firewall, with the csc version as 6.3.1172.0. I have a public Ftp server and when i ever i transfer the zipped files more than 50 MB or 70 MB or more than that, it fails. I used to upload by clicking the ftp site and copy past the file to the location. After a certain point of time, the download fails with the below error on the explorer.An error occured copying a file to the FTP server. Make sure tou have permission to put file on the server.Details: The operation timedout
Firewall log is below.
ABCFTP1|21|10.120.110.162|1257|Teardown TCP connection 48091783 for Internet:ABCFTP1/21 to XYZ:10.120.110.162/1257 duration 0:00:27 bytes 656 TCP FINs .
-- When i remove the service policy from the firewall, and try to transfer the files, it goes through without any problem. ena
-- Pls check the attached screenshot of the ftp settings in CSC-ssm. There is no problem with downloading files from the server.
I am a new network admin at my company, and I am investigating a problem that is on a network designed by someone no longer here. So, I can't ask why things were set up the way they were. Anyway, here's the issue:
We have 50Mbps WAN connections between locations. The WAN devices are 3750s, but the port plugged into the providers network is a layer 3 port. Config is below for one of the ports: [code]
So, these are Gig ports, but our service provider limits to 50Mbps. When we do a data transfer, we can't exceed about 20Mbps total on the circuit. The data transfers at maximum 15-16Mbps.
I'm not familiar with QoS. I've tried to read more about SRR, but don't understand it well enough to know. Are the QoS settings creating this restriction? Our provider swears that the bandwidth is allocated and its not being choked on their end. I have not taken off the QoS config to test it that way because I'm not 100% sure if its needed and serving some purpose. I don't want to break something in order to fix this.
Is the QoS causing this? Do I need to put a bandwidth statement on the port? Should we be using routers and LLQ?
I administer a wired SOHO network at a business I own, which is nothing more than a XP Pro machine which doubles as a file server. Typically, there are only 3 or 4 work stations in use at any given time, with 3 printers being shared. Backups are done after hours through portable USB. I have a home quality Netgear router behind a cable modem, and unfortunately need to use two 8-port unmanaged switches due to limited cabling between the workstations and the server. Said switches/cabling could prove to be the culprit, except that it used to work nicely.
A few months ago, while browsing the shared folders where the bulk of the approximately 180 Gigs worth of largely graphics files...(browsing from ANY of the terminals)...I began to be aware of random delays of up to 30 seconds or more. It seemed to be a sudden change, but has grown worse over time.
The files in question typically reside under several subdirectories, ie My Network Places/GID/Designs/Stan/Photoshop Files/TeeShirts... and browsing to the actual goodies progresses nicely until the VERY LAST directory, then WHAMMO.....XP flashlight goes back and forth, back and forth, back and forth.....you might wait half a minute before seeing the actual filenames in the window.
Its exasperating, and can randomly happen even if I'm the only person in the building, and the "server" seemingly has nothing else required of it.
Since about 3 weeks ago my DSL has been getting totally random ping spikes, from under 40 to over 1500MS for minutes to hours on end. Nobody else is using my internet, I've verified this. There is nothing sucking up bandwidth on any connected device or computer, as far as I can tell through troubleshooting to the best of my ability. I tried switching to a Cisco X2000 modem/router combo and it did nothing, still totally random latency. Also, when I called AT&T about this, they didn't even know what ping was. They ran an upload/download speed test (which is still mostly consistent regardless of latency) and told me I was basically making the issue up.
I'm presently experiencing an issue with my Latitude E5410 notebook where the NIC disconnects during large file transfers. For instance, if I were to copy a large file (50+ MB) from a network drive (or vice versa, copy a 50+ MB file from my notebook to the network drive), the network icon in my taskbar suddenly changes to "No Network Access", the transfer fails, and I can't access any network resources until restarting my workstation.
At first I thought it was the network backbone in our office (SonicWALL Gateway + Dell PowerConnect switches), but this error also occurs at my house with my own networking equipment (D-Link) and NAS. The Latitude E5410 notebook is running Window 7 Professional SP1 and has a built-in "Broadcom NetXtreme 57xx Gigabit Controller", and a "Dell DW1501 Wireless-N WLAN Half-Mini Card". However, this issue seems to only occur with the Broadcom adapter when I'm physically connected to our network; when the Broadcom adapter disconnects, I can connect to our local wifi network and access network resources.
So I used to use a Thomson TG585v7 modem router (wireless) as my means of connecting to the internet, the aerial cracked on it and I began getting dropped connections, so I went out and bought a D-Link DSL-2730B modem+router. I am hooked up wirelessly to the internet as there is no phone jack in my bedroom, and I experience massive and prolonged lag while playing call of duty 4 multiplayer, which I never had before with my old Thomson modem. My ping also shoots up to about 400 and then 999 while I teleport around the map.
Whether it be downloading or just trying to watch a video on youtube. For some reason everytime I try to download something it appears to start fast but then it basically just stops. I'm running windows Vista and I've tried going into the router security settings and unchecking Block Anonymous Internet Requests.
Vista 64 Intel Pro 1000 with latest driver Here is a shot of the lagometer in COD Black Ops when all is good. I used to see this with my old WRT54GS and connected at 100Mbps Full Duplex or Half Duplex and I currently see this when connected through the E4200 at 100Mbps full or half duplex AND when connected via Gigabit via one of the 4 ports on the back of my cable modem, a Motorola SBG6580 [URL] This next screen capture is what happens when I try to connect via Gigabit thru the E4200. It either starts out like this right away or within 30 seconds to a minute this will start to occur. I believe the red spikes indicate packet loss. [URL]
Recently purchased a Linksys E4200.Computers on network:Two hard-wired gigabit desktops: one Windows XP, one Windows 7One hard-wired 100mbps desktop running Windows 7One laptop with an Intel 4965AGN running Windows 7.File transfer rates between any of the desktops and the laptop is very slow: ~2 megabytes/s
File transfer rates between the gigabit desktops is good (~50 megabytes/s, hdd bottleneck), transfers between the 100mbps desktop and one of the gigabit machines gives ~10 megabytes/s.Currently running on the 5Ghz band, connected with N at 300 megabits, good signal strength. Disabled mixed mode on this band, enabled N-only.Use a scanner tool, I can tell that there are no other networks on 5Ghz band.Also, tried 2.4 Ghz band and got similiar low speeds.These transfer rates are much below what other people report for real-world throughput. Any ideas? I know there is an Advanced Wireless config page, is there a setting there that might work if adjusted?
Our 2811 WAN router is experiencing a high volume for huge buffer misses with some failures. Should we look into the automatic buffer tuning command as our IOS supports it. Does the router need to be reloaded after? Has anyone experienced any issues with this command or having traffic dropped (even biped)?

This is a new RV180 install. FTP data transfers fail in binary mode. By fail I mean the first packet sent, isn't accepted (acknowledged?) by the FTP server (Network Solutions, Passive Mode), . If I pull the router and replace it with an old D link router or 5th gen Apple Airport Extreme, everything else the same, it works OK. I lack the tools and knowledge to proceed beyond this point.
I plan on starting a high speed LAN for my Gaming LAN party's. We send 100's of GB of data over our LAN networking when we do this, so i need a good switch that can handle the stress of the massive data transfers. It needs to be a gigabit switch and at least 8 RJ45 ports.or is there a different one i should get all together? i cant spend a butt load. url...

I have upgraded to the latest firmware which solved lots of problems regarding unstable wifi connection as well as BitTorrent / P2P transfers.But I also observed that when my BT is on (Transmission for Mac) at around 50KB/s upload and download, my network latency hikes up from some 30ms to 500ms which affects a lot on web browsing or other apps requiring Internet.My BitTorrent app is showing I am merely making some 20 peers connection so I am not convinced that is an ISP problem but it's more about the router.
We have the following architecture for Internet access:
LAN ---- CISCO-CHASSIS----FIREWALL-----INTERNET
My concern is about PAT, for LAN users Internet access: I would like that PAT is performed by Cisco chassis(in my case, a C4500), not by firewall (which means: local IP addresses for flows from LAN to Internet are all natted with the same public IP address).Are there some drawbacks to this design? I guess there is no problem for classical flows, but what about flows with specific comportment (such as FTP) on Cisco routers?
I'm currently running 8.3(2) on my 5520s in an active/standby config. The 5520s have the 2GB RAM upgrade and 256MB flash card. Are there any CPU limitations in going to 8.4? I read the release notes but didn't seen anything about CPU. I heard through the grapevine that a 64-bit processor may be needed. We currently have the Pentium 4 Celeron 2000 MHz CPU.
I have a question for Cisco Cat.2960-s Flex Stack switches which are installing on our sties. Two of 2960-s Stack switches as access switch and two of Cisco ME 3600X Series as distribution layer switches are to be installed in our sites. In case of two stack switches, One is will be a Master and the other one will be a member logically, as you know. So, if the master fails, the other one automatically becomes the stack master following a well-documented election process.
Now, it is my question. How long takes to be a stack master from a member switch ? I cant find it on white paper of Cat.2960-s flex stack . And also, I heard that sometimes a member switches don't election process when the master fails as a result, all stack members become a panic. Is that really right ? In addition, I heard that the stack switches have many troubleshooting points than stand alone switches. I really wanna know if the stack switches are good solution for resilience of huge network site. I'm waiting an answer from those who have experience of maintenance or installation.
I'm trying to use a 5520 to test something but the bandwidth seems pretty low for the product I'm testing over it. Can anyone tell me if there is a bandwidth limitation by default? I'm seeing 1.5mb/s average with spikes to 6mb/s or so. On the ASA5550 I was seeing usage up to 80mb/s.
