WNDR4000 Corrupting File Transfers?
Sep 29, 2011
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.

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.

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 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.

is there anything I can do to prevent this? My last password was yUe!k837A!*5L^PcWgw@H06^ using WPA2-PSK [AES] and they still get through? I turned on the allow list to only allow certain devices through and they somehow add themselves to this list as well? WTF?

I recently bought a Netgear WNDR4000 router. The wired network is working fine, but the wireless network is giving me problems I don't understand.
I am using the following equipment to connect to the wireless network:
- Samsung Galaxy S2 mobilefoon (supports N speeds)
- Asus laptop (supports G speeds)
With both devices I want to connect to the 2.4 Ghz (b/g/n) wireless network with the following settings:
- Channel: auto
- Speed: 145 Mps max.
- Security: WPA2-PSK [AES]
- Preamble modus: long
- Fragmentation length: 2346
- CTS/RTS: 2347
Latest firmware has been installed.
Here is what happens:
- When resetting the router to factory settings I can connect with both devices mentioned (security is not enabled)
- When setting the WPA2 security key for the first time, I can connect with both devices.
- When I try to connect with either device for the second time I cannot connect, messages (from mobile phone):
The nework SSID is visible Trying to connect Connection broken Network remembered
And then a loop is present that keeps trying to connect, but almost never succeeds. Maybe once in a hundred attempts. When a connection is made, it works fine for as long as the connections stays present. After the connection is broken, it all starts over again. The 5 Ghz network is behaving exactly the same (only tested with my mobile phone, laptop doesn't support 5Ghz network).
I have lowered the speeds and tried different channels, but behavior stays the same.

My laptop is unable to connect to our router unless I am right next to it. I am in a split level house. When I go downstairs in our family room the laptop will not connect or is very slow loading. Once I move the laptop next to the router everything is fine.
The lap top is an HP Pavilion with Windows 7. The router is netgear n750 WNDR4000. :Laptop was connected to internet this afternoon now this evening I have problems.

So I recently moved a little bit away from where I was. My new area only has one internet provider available called "Hot Spot". We got the 10 down 5 up plan and I get what I paid for in that respect. My issue is that it won't even stay up for longer then 20 minutes. At first I was using the Netgear N750 WNDR4000 router, but I switched over to my ASUS RT-N56U router thinking it might fix the problem. Same thing happening with this ASUS, but when it goes out and I try to load a web page I get the error "you have set the wrong dynamic or static IP address for your RT-N56U." The router setting is set on automatic IP so I'm not sure if that's the problem. I called the ISP and told them I have Dish for TV and they said that is most likely the problem as it can often conflict with the IP or something like that. So I called Dish and they sent me this "Hopper Internet Connector" which supposedly fixes this issue because it directly connects it to the router instead of wirelessly. That still didn't fix the problem. I have tried turning wireless off completely and it still happens. I have reset the router to factory settings probably 4 times. I really don't know what else to do..

My friend has had constant issues with his wireless network using his dated Linksys router. So he finally decided to upgrade to the Netgear N750. It's a dual band router that simultaneously broadcasts 2.4 and 5 GHz bands. He setup the 2.4 band for the laptops and mobile devices to access, and the 5 band just for gaming on his xbox 360 Slim. He immediately ran into a problem. The 360 slim's built-in wireless card only picks up 2.4 GHz frequencies. To remedy this, he purchased Microsoft's xbox 360 wireless-N adapter as it can pick up 5 GHz frequencies. However, there was no change after plugging the adapter into the 360 slim. His HP laptop can see the 5 GHz network just fine, so we know it's being broadcast. Could it be the xbox is out of range of the 5 GHz band? Is the adapter not functioning properly with the 360 slim?

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 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 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?

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.

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?

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...

Region : Hongkong
Model : TL-WDR4900
Hardware Version : V1
Firmware Version : 3.14.3 Build 130320 Rel.39025n
ISP : PCCW Netvigator
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.

I am working on a Drupal site which is on a virtual server (the way it's been explained to me). I've been told I need to work with it through webdev. So I can copy a file off the server and onto my local machine. I make my edits and then try to upload it to the server. I get locked out with the message: Error 0x80070021: The process cannot access the file because another process has locked a portion of the file. I have tried shutting down my code editor, opening and closing the connection, tried different methods of reaching the server (Cyberduck and through Window's map network feature) to no avail. What can I do?

I'm baffled by the poor performance that I'm seeing when passing traffic between my two Cisco SG switches.
The configuration is as basic as I can make it, no VLANs, QoS or bonding. Both have been updated to current firmware as part of the troubleshooting process.
When I transfer data within one of my switches I see 50/60Mb/s. When I pass the same traffic between both switches I see 0.6 Mbs/ or less.
I have tried to eliminate every possible factor including switching out the cables. No success.

I have a media/storage pc set up in the living room, with my main pc (actually capable of handling the newer 3d content im getting) in the bedroom. All files are downloaded to the Media center pc. I recently changed the download location to drive D to alleviate stress on the operating system drive. Usually when I wanted to transfer files from the Media center to my pc I would go through computer - network - media - location of file. I have found I can't do this to access drive D on the remote Media. Is there a more efficient way than copying files from drive D to C on media just so I can pull them to my main pc? I have tried copying while in remote and pasting on my main pc desktop. It worked great for a 1kb file, but fails every time at 5gb files.

We have set up 1 computer (from now Computer A) running on windows xp as a "server" with other computers in a MSHOME group (from now Computers B -D). File permissions and sharing was set up to allow all remote users (Computers B-D) read and write access. This is however not always appropriate. Is there a way in which we can share a specific file or folder with Computer C (read and write) but not with Computer B and D?
