AR928X Very Slow Copying Over Wireless Between Machines / But Internet Works At Normal Speed?
Mar 3, 2012
I have a laptop (let me call it A) with Intel Centrino 1030-N wireless (iwlwifi module), running Arch Linux, and another laptop (I will call it B) with Atheros AR928X wireless (ath9k module), running Ubuntu 11.10. They connect to a wireless network provided by a D-Link DI-524 router (802.11g), which in turn connects to a DSL modem (10Mbps/1Mbps link)
Copying files between those machines, either through scp or mounting a share via NFS or Samba, is very slow (at most 200 KB/s) and sometimes fails (times out), even when both machines are inches away from the router. However, downloading files on either machine works correctly at the expected speeds (~1.2 MB/s).
I ran iperf, as recommended in a comment, and it gave me this: [code] The bandwidth is very low, as can be seen from those results.

My Main computer (which has a wired connection to router) internet is running so slow, i mean so slow that i cannot even do a speed test, it keeps failing, im continuously getting server timed out messages when browsing, and to watch a youtube video of 1 minute long it will take about 5 - 10 minutes to stream it before i can watch it. However despite the above the two laptops and ipad work great, i have a braodband speed of around 16megs. Now here is everything i have done so far. After calling my ISP to se if it was their fault, which it turned out not to be, they got me to change all the DNS and IP settings to manual, they gave me all the numbers to put in. Again that did not work so i used namebench to find the quickest DNS servers for me, that didnt work ethier so i just reverted all settings back to automatic as they were before.

I have a router that needs to be reset to get the internet speed back to a usable speed. It is a fairly old router (D-LINK DSL 2730B) and it does get quite annoying. There is allot of devices connected, which may affect the speed, but I am sure it shouldn't change upon reboot. I literally reboot every hour or 2 during peek periods.

Have been experiencing speeds of max 2.5 Mbps for transferring files between Windows 7 machines connected wirelessly to a Billion 800VGT router. A speed of maximum 18 Mbps was achieved. No matter what I did to adaptor settings it was the best possible. Have 6 wireless machines which I cross checked multiple times using Lan Speed Test by Totusoft.I then disabled the wireless security (WPA-PSK) on my Billion 800VGT router and secured the network by using the Wireless MAC address filter. My speed immediately increased to 11Mbps between wireless machines. Speeds to machines on fixed lan increased to 26 Mbps.

I have a 512MB USB Flash device and was able to boot the IOS on the C2960 from it.After that i tried to Copy the IOS file from the USB to the system flash, but it could not find the USB Device.At plugging in the device the systems tells me: "Transfer type 2 not supported" I configured the USB device in NTFS and FAT both are able to boot with the ROMMON, but the normal system does not accept them and i know i can do the copy over a TFTP from my laptop, but it is strange that rommon accepts the usb device and the system does not?

I am working on a small business network. 8-10 computers, usually only 3-4 being used at any one time. I'm trying to improve network file transfer speeds between the local machines and a network READYNAS NV+. There are both 32 and 64 bit OS's in play. Between the READYNAS and the local machines are two non-managed switches (jumbo frames capable) and a patch panel. The cable from the READYNAS goes into the first switch, then out of that into the patch panel then into the second switch, and then out to several local machines.
Though i would love to improve performance to all the local machines, I am primarily concerned with one in particular. It has Windows 7 64 bit and an onboard Broadcom Netlink Gigabit network adapter. This device does NOT have a Jumbo frames option in the advanced settings. Here's the issue: When copying files from the READYNAS the upload speed is only 16mbps (jumbo frames enabled on the READYNAS) if I turn jumbo frames off on the READYNAS the upload speed drops to 9mbps. Just FYI, this is a photography studio and the files are always LARGE.
I have several questions that hopefully will lead to an illuminating discussion. 1) Is it possible that the universal patch is in any way a problem? Sorry if that is totally stupid, but I've never encountered one before. I understand routers and switches, but this patch thing is new to my experience. 2) Is having two switches a bottleneck? 3) Is it possible that the onboard Broadcom network adapter is junk? Why doesn't it have jumbo frames options? 4) Could I get better performance from an add on network card in a PCI-E slot and a couple of managed switches?I realize I'm all over the map here. Bottom line, I've got a small network situation here. Very simple, uncomplicated layout. All I want is better read/write performance to a single READYNAS NV+ to a handful of local machines. If I need to settle, I can live with better performance to the one single machine. 16mbps just seems tragically slow.

Lenovo T61P
Win 7
Wireless Connection (Router Linksys WRT54G2)
I installed Comodo's Firewall and during installation I accepted to install the Secure DNS too. Afterward I noticed my web-pages loaded slower than usual. They weren't extremely slow but definitely slower than what I've been accustomed. I tried some OPENDNS servers and others to see if it made any difference but it didn't. I also went to my router's setup page((http://192.168.1.1/)so I could manually add the previously mentioned DNS servers. I finally decided to revert back to my old DNS list. To disable using the Comodo DNS servers I did the following:Wireless Network Connection Properties-> Internet Protocol Ver 4 (TCP/IPv4)-> Properties -> Select "Obtain DNS server address automatically"I also went into to my router's setup page (http://192.168.1.1/) to set my DNS list to zeros so that I can get back my default ISP's DNS servers (207.69.188.185,186,187). However, website loading is still sluggish.I thought the issue might just be a temporary hiccup from my ISP but my roommate doesn't have these issues. We tried a speed test at dslreports.com and the results were weird. On my laptop the results were 8500+ Kb/s with a 279ms latency. I was 10 ft away from my router.

I've recently purchased a WRT160N router, and I'm using it in conjunction with a WMP54G wireless PCI card. I've set the router up to my requirements, and can get a stable wireless connection.. but internet speed seems excessively slow. While I'm able to get up to around 4MB/s transferring files over the network, running speed tests, it consecutively shows my download speed to sit around 400KB/s, whereas I'm able to get a steady 1.1MB/s on another desktop that is wired. Disabling the LAN adapter on that computer, and connecting via wireless, brings down the speed that that computer is able to get to around 400KB/s as well. Hence, I don't think it's my wireless cards, but something to do with the router itself.I'm also experiencing lag spike issues in online games, which I can only attribute to the current wireless setup, because I've previously had no issues with it. All relevant ports are forwarded, so that is not an issue.After doing some Googling on the subject, someone had suggested running SpeedGuide's TCP Optimizer, and changing the RWIN - I ran it, and set it to the 'optimal' settings, and after a reboot the wireless seemed fine - I was getting just a tad under what I should (about 950KB/s).. but after a short while, it just went back to 400KB/s. After further investigation, it seems that Vista automatically changes that RWIN value to optimize network traffic.. but I never had this issue with my old wireless gear, so I can only assume that the way Vista is reacting is based on the way the router is interacting with it.

I came home yesterday and my Internet was really slow. I later found out that it was due to my Linksys E3000 because if I bypass my E3000 and go directly to my cable modem, it work just fine.I tried reconfigure, update firmware, factory reset and none of these has worked.

I just bought a Cisco e1200 router... and the wireless connection is way too slow, when navigating through the web, but when using speed test, the connection seems fine, but still it even takes more than usual to open simple pages, lets say Google... i usually watch streams and now that i cannot do... when i connect directly i can do everything as usual...as i have read, i change channels, but still no improvement, i have the latest firmware, on my range there are only 2 more available connections... i even tried disabling/enabling the WMM... We all know that having extremely slow internet must be the real "Mayan apocalypse"

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

Region : Brazil
Model : TL-WR841ND
Hardware Version : V7
Firmware Version : 3.13.9 (Last)
ISP : NET Virtua
I've bought a TL-WD841ND and was using it normally.
After I arrived from a trip, the internet speed by wireless and by cable is only 0,5~0,7 Mbps...
My internet connection is 10 Mbps, and if I plug direct on the modem, there comes the real speed (9,7 Mbps), but connecting by the router, the speed is 1/20 of what should be. Before my travel i was using it normal, and no one has changed any configuration.
So i've updated to the last firmware avaliable on the website. So i've rebooted it and the "configuration" LED keeps flashing...
I would like to know if this led flashing is normal: (here is a video that i've done: [URL] and what could be happening. ps: connecting by cable, the internet speed is also the same (even after the factory settings reset)...

My Cisco E3000 has slowed it's Ethernet speed so slow that it times out when going to Facebook, YouTube or any site that is complex. It worked fine until one day it just gave up. It's connected to DSL Modem with Ethernet To a Apple Mac G5 power PC There are two other older macs connected via Ethernet, same problem. When I took the router out of the chain, and connected G5 directly to modem, normal internet speed. My firmware is up to date. Both wireless bands work great. When I look at Cisco Connect, everything looks normal. factory settings.

I have a Cisco ASA 5510. I am trying to copy large files between DMZ and INSIDE network and it is copying at awfully a slow speed. I thought it might have been related to duplex mismatch but it doesn't seem to be. DMZ interface is set at 100 full duplex. I programmed the port on the managed switch where the DMZ uplink is connected to be 100 full duplex. I even hard set the NIC on server to be 100 full. Nothing worked. So, I come to a conclusion it isn't the duplex mismatch but there gotta be something else on Cisco ASA. I was googling for this issue and came across it could be a QoS policy. Now, checking my ASA I see a any to any global service_policy where it is defined to inspect certain protocols where 'netbios' is one of them (among others such as 'ftp', 'tftp', etc. Could the slow copying be related to the above policy? Could there be a bandwidth limitation between DMZ and INSIDE interface? How do I check?

Recently my desktop has experienced very slow download speeds (~0.11 Mbps), however the upload speed appears to be in line (~2.0Mbps). These numbers are taken from Comcast's speed test (my ISP). It is obviously a problem with my PC because everything else on the network (PS3, Laptop) have great signals with no problems. I just recently reverted the Desktop back to its factory state, and everything was working fine for a couple of months. The desktop in question uses Vista 32-bit and the Belkin Basic USB Wireless Adapter.

I am having difficulty uploading files on the internet because the speeds are so slow. My download speed is 23.88 MBPS, bu upload is .3 mbps. This seems to be a recent problem. The other computers on the network get upload speeds of 5mbps and do not have any problem, so I think there is some problem unique to this computer, and not a network problem. I can't back up my files because the speed is too slow.

I am not able to connect to any webpages in normal mode, even after restarting i still have the same problem [However it works in safe mode with networking]. The network connections show that it is connected and the signal strength is excellent. I then have to keep restarting the laptop like 3 to 4 times and it works. Its kind of frustrating to keep doing this all the time and besides i am scared by restarting the laptop so many time can harm it.

I've been gaming all day and my ping has been extremely high. I figured it was someone in my house downloading something but now it's... 1 a.m. I checked my whole house and shut down everyone's computers so I'm positive no one is stealing my bandwidth.

It was monday night when it started playing up. I literally have had it right now. To watch a simple 1 minute long video on youtube I will have to wait about 10 minutes before it is fully loaded. It takes about a minute to load an internet page and it is not just my computer, it is also happening on all other wireless devices and wired (3 laptops, 4 phones, ipad, ipos etc.)

My brother is spending far too much time on a silly internet game on his laptop (Maple Story) and its effecting his school and social life. We're trying to find a way to slow down how fast his internet speed is so his game runs poorly, hopefully making him stop playing. I've looked into blocking programs over routers but it seems like a tough job.

I live in a house with 5 other students. To be fair, it is in the middle of nowhere so the internet is probably very slow anyway, but here is my problem: Skype is so slow I can only just make a voice call, webcam chat is off the cards. YouTube and other videos are so slow to load I cannot watch them. My Xbox 360 constantly disconnects from the wireless, so I cannot play online.
