Cisco :: Extremely Slow Data Transfer Speeds On 1130AG
May 16, 2013
I've recently upgraded the configuration on one of our 1130 series standalone access points. I've implemented RADIUS authentication, WPA2 encryption etc. in an effort to make our network more secure. While this part seems to be working as planned, our data transfer speeds have taken a major hit. On our test AP, with only one laptop connected, the laptop will report a connection at 54 Mbits. When using any speed test service the speed reported is approximately 15 Mbits. We have 100 Mbit internet, and desktops connected to ethernet show much higher speeds. When transferring files via our own LAN, data transfer rates average approximately 2 Mbytes/second. I've tested this on 3 separate laptops, some relatively new, and it seems they all get the same speeds.
Long story short, our wireless seems to be operating under a third of its reported speed.
Just relised this problem after trying to leech some stuff from a friend from his pc at a lan My connection seems to go REALLLY slow. Heres a pic nobody else is file copying and its the same from every pc.
We have an ASA 5510 and are experiencing unbelievably slow speeds. I noticed a problem last Thursday with users complaining of slow speeds and realized our interface had a ton of errors and was running at half duplex. I contacted the ISP (we are connected to their 3750) and they swore up and down they were set to full. So they had me switch to full and the interface shut down. I asked them to switch to auto and the interface came back up and we went to full, and of course the errors and colisions stopped. However the errors and packet drops have not stopped. The ISP sent out a technician and they determined it wasn't a problem on their end by plugging in a laptop and testing the speed--that worked fine. Eventually I plugged in a Sonicwall and bypassed the ASA completely and that worked fine. We plugged the ASA back in and we we went back to dropping packets. I put an old config on the ASA and oddly enough it seemed to have fixed the problem but we were still dropping packets. So I put the most recent config back on and that worked fine up until today. We're back in the some boat we were last week. So my first question is when I do a show int and see packets dropped - is that normal because of ACLs etc, or would that be show in another place? Here's an output of show int and show asp drop:
HQ-ASA# show asp drop Frame drop: Flow is denied by configured rule (acl-drop) 3366 NAT-T keepalive message (natt-keepalive) 423 First TCP packet not SYN (tcp-not-syn) 406 TCP failed 3 way handshake (tcp-3whs-failed) 135 TCP RST/FIN out of order (tcp-rstfin-ooo) 462 TCP SYNACK on established conn (tcp-synack-ooo) 46 TCP packet SEQ past window (tcp-seq-past-win) 50 TCP invalid ACK (tcp-invalid-ack) 9 TCP Out-of-Order packet buffer full (tcp-buffer-full) 29 TCP Out-of-Order packet buffer timeout (tcp-buffer-
[code]....
I have not made any configuration changes to the ASA ina couple of months. The interface counters were cleared about 45 minutes ago if that's how quickly the errors/packet drops are adding up.
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 just replaced my malfunctioning E4200 with the new EA6500 and the speeds are almost like dail-up. I haven't changed ANYTHING in regards to the setup, so I don't see what I could possibly be doing wrong. I even went as far as hooking up the old E4200 to my laptop while having the EA6500 hooked up to my desktop so that I could cross-reference the router settings. They were exactly the same.
All I want is functional Wi-Fi in my house like the rest of the world. Unfortunately, I cannot have that for whatever reason.
Now that I said that, Let's me get down to explaining my issue. I orginally owned a Linksys WRT350n. This router worked fine for years, untill one day I decided to do a speed test on my new Motrola Atrix. My Wired computer gets ~22000kbps down and 4000kbps up... My wireless speedtest on my Atrix yielded 2000kbps down and 4000kbps up. I assumed it was the phone, so i went and tried every other wireless device in my house. Everyone of them got the same result.. 2000kbps down.. 4000kbps up.
At this point I went into my router settings and tried every available channel, all of them yielded the same result of 2000kbps down and 4000kbps up.. At this point, I assumed it was the router. Ive had it for a few years and figured it was just reaching EOL. I rushed to my nearest bestbuy to pick up a brand new Linksys E4200. I brought it home, hooked it up and was eager to test my new wireless speeds. Unfortunately the same results of 2000kbps down and 4000kbps up was the yield. Once again, I've tried every possible channel with no change to my speeds. At this point I called up Linksys/Cisco support.. They were POSITIVE it was a hardware issue and had me exchange the router, even though I informed them i had the same issue with my older router of a different model. I went along with it anyway, and exchanged my router. Same issue. I called Cisco/Linksys back up and informed them, and basically they told me "they'd make a note of the issue and call me back at a later date."
I downloaded a WiFi Analyzer on my cell phone. Theres only two other dectable networks in my area, and they are low low low signal. So, I don't believe it's heavy saturation. The router is in the same room as 3 of the wireless devices that get 2000kbps down/4000kbps up. So it's not range either.
Download speeds, per speedtest.net and speakeasy, are about 20mbps.When the speed test gets to the upload part, it usually hangs or takes a long time before giving me a result of about 0.04mbps. Basically, it's so slow, it sometimes just gives up and times out.This translates into a real shoddy internet experience because something as simple as choosing airline tickets requires your computer to "upload" your choices. And of course, if that doesn't happen within a certain amount of time... Timeout! I have tested the connection without my Netgear FVS336G Dual WAN router in the way and it is much better so I'm certain it's the router.When I tell the router to use WAN 2, which is where my AT&T DSL connection is on, the upload works just fine (about .4 mbps - I'm provisioned at 512kbps so it's fine).Also, this is the case on ALL computers on the network - wired, wireless, PC, Mac, iPhone, iPad, you name it. So, it's definitely not device specific.
Ive been doing everything I can to try to enhance transfer speeds between my home server and desktop pc. [code]
Just drag and drop copying on my network, a 7gb file started at 20mbps and immediately dropped to ~11mbps where it stays.I took the time to run cat 6, bought a decent router, and (2) intel NICs, I feel like I should be getting much better transfer speeds than this.
Im having a problem transferring files to a shared network folder (my server's folder), its transferring files at ~20KB/s Thing is, I can copy files from the server to my computer at 90MB/s.I can also copy from my computer to my brothers computer also at 90MB/s.And copy from my brothers computer to the server at 90MB/s.But only 20KB/s from my computer to the server.My server is running WHS2011 by the way and my computer and brothers computer is running Windows 7.My entire network is wired and tested with a 1Gbit connection. and im using a Linksys WAG320N router.

I'm having problem with slow wireless trasnfer speeds. 129kb/s slow. So here is my set up. Desktop with a 100MB nic card, running windows 7 ultimate, connected to linksys wrt320n running dd-wrt. then i have my laptop running windows 7 ultimate, connected to my wireless network.
I have tried coping files in the homegroup and outside of the homegroup.
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
Very slow transfer speeds problem with this router. When I put the router in the system, my transfer speeds drop from 12 Mbps to 3 Mbps. I've updated the firmware to the latest version but that doesn't work. The most frequent suggestion is to upgrade the firmware which I have already done.
[code] Wireless transfer from HTPC to Windows Home Server peak at 8-9 MB/sec. Note that my WHS and my Winn7 Gaming rig are both on the same physical switch, but the same exact wireless file transfer from my HTPC to Windows 7 gaming rig hits consistent 35-40 MB/sec, 4x faster and which is what I expect. Wired transfer of same 4GB test file directly from gaming rig to WHS tops over 100MB/sec so it is not a problem with the WHS writing to disk or wiring. So the question is, what could possibly be bottle-necking my upload from HTPC only to the Home Server? I have tested a Netgear R6300 with the same results as the Asus router.
I've just bought a Synology DiskStation DS412+ and put 2 x 3TB Western Digital Red drives in it, set up in RAID 0. It's currently plugged in to my gigabit Netgear switch.I created a user with full permissions on the NAS, created a share, mapped a drive on my Windows 7 PC (also gigabit ethernet) and tried copying some files, but I'm getting painfully slow transfer speeds (< 40KB/s - yes, kilobytes, it's not a typo!
Does anyone have any ideas why it'd be so slow? There's loads of reports online of people getting > 80MB/s from this NAS.
I've copied files from this PC to my MacBook Pro in the past and got decent enough speeds so it shouldn't be an issue with the NIC on this PC, or (hopefully) the Netgear switch it's going through.
I am seeing something pretty bizarre: when trying to copy files between two computers (both Windows 7 SP1 64bit), both physically plugged into the back of the E4200, I see extremely slow transfer speeds: 1.0-1.1 MB/sec. Both computers are fast (i7-2600K, both using SSDs) and both have gigabit ports (and the 4200's web UI shows both ports in question as operating in gigabit mode).
This is so slow as to be sort of funny. Each of these computers see speeds well in excess of that when transferring between the computer and outside internet sites...so it's kind of funny that two computers plugged into the same switch in the back of the 4200 see 1 MB/second.
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'm using Pix 501 with firmware: Version 6.3(3)I have problem with Pix 501:
+ transfer rate data between interface outside and inside very slow, even between 2 interface inside. + I have test file transfer between 2 PC connect via interface inside. + Results transfer 1 file 1MB with total time 60s
I don't upgrade software current from 6.3(3) to 6.3(5) via TFTP. It's error Please see attach file.
So I have a really neat computer sitting here, 2500K, P8z68-v, samsung 830 64gb ssd, corsair vengeance 16gb, deskstar hdd, firepro v5800
I have a non-descript trendnet 56K v.92 dial up modem installed to pci slot1 on my mobo.The phone company says they can't get a quicker connection than 31.2 Kbps established to dial up users in this area.The real issue is the data transfer rate.I have seen it reach as high as 6.xx Kbps but generally hovers around 2.5 Kbps.Now it is down to 1.xx Kbps and I took the last 48 hours downloading all the updates for windows and several other updates for hard ware etc.Now I need the ATI firepro update and 114 Mb will take over 16 hours at my average speed, and some 32 hours at the new slower speed

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?
I have a home network with a media center. I have the hauppauge 1212 HD pvr so that I can record video in HD to my hard drive. I want to stream this content to the differnet PCs on my home network. Every TV in my home I have hooked an HTPC to it. I use them to play dvd's. Stream netflixs etc. My problem is that I am getting a terrible transer rate wirelessly. 600 -750 kbps. (tested by transfering large files from pc to pc) All computers have 300Mbps wireless n cards. all are recieving max signals. There are either 3 or 4 pc's connected at a time depending on whether my laptop is connected or not. Obviously this is way to slow to stream video. Made sure my network name is unique. changed to wireless channel 1 I do think I have WEP 64bit encription could this be an issue?
My Belkin F7D4301 Router has the fastest wireless speed of maybe 2MBps but wired with a cat5e cable to my asus laptop of almost 7MBps. I have a one smart TV, one blue ray, one roku, and a nexus 7 using the 2.4 channel.
My Wireless 2.4 settings are channel 11, Extension channel 7, Wireless mode N (have tried with just g and b, g, and n modes), Bandwidth 20/40, Protected mode on, QOS off.
I've talked to Belkin tech support, they are the ones who had me set up my 2.4 channel this way but my wireless speeds stay just under 2MBps, they just want to keep sending me the same model Router because they think each of the new ones they send me is defective.
Am I doing something wrong or is 2MBps the best wireless speed I'm going to get?
How can I optimize my router to get maximum transfer speeds? I average 72 Mbps.Notebook-Speedtest.net 31.58Mbs down/3.08 up. I'm just confused about transfer speeds not being 300 Mbps. Can or should I correct this? When I purchased router it said the transfer speeds would be 300Mbps.
PC1: Connected directly through 1 gigabit ethernet LAN.I'm using a MSI GT640 notebook with a onboard NIC, Ralink Techology, Corp. 802.11bgn 1T1R mini Card wireless network adapter. Driver date: 7/6/2010, Driver Version: 3.1.8.1. ( WLAN RF module Ralink RT390, MSI MS 6891).
For the past week my internet has been extremely slow, I can watch a South Park episode online and it'll take me at least one hour before I can watch the entire thing because it keeps buffering every 20 seconds. I can barely browse MMO-Champion because it takes one minute to load. Every site takes forever to load. And it's just on my stationary computer. My laptop and mobile phone works just fine. It feels like I've tried everything:
* I've cleaned cache and cookies and stuff like that with CCleaner. * I've used my console and done all that ipconfig stuff with /flushdns etc etc * I've used my console and done all that netsh stuff as well * I've tried to reset my router * I've tried to use that Microsoft Fix-It program to do whatever it does. * I've looked through my computer with my anti-virus and anti-malware * I've installed the latest drivers for my network card/adapter * I've fixed options on the computer that would allow my computer to perform better * I've purchased another wireless adapter just to see if that was the problem * And finally, yes, I've tried restarting the computer
I have tried 2 DIR-655 routers now, revision B1, firmware versions 2.04, 2.07, 2.08beta and a number of laptops and wireless mini pci-e nics and I simply CAN'T get faster than about 10 megabytes/sec transfer speed from a wireless laptop to a wired gigabit desktop.
Is this just simply a limitation of these routers? Can they simply not transfer data at decent speeds? I've seen real world transfer speeds near 12 megabytes/sec on a DIR-615 and I assumed the limiting factor there was the 100megabit wired connection.
I've spoken to a dozen different D-Link phone support workers
I've recently had Centurylink's Prism service installed and at the same time my internet connection upgraded to 10Mb. When they installed the new service, my modem was replaced with a Cisco DDR 2200-CL modem and router in one. On Monday of this week my internet speeds had dropped. I check my speeds on speedtest.net several times and it was under 1Mb each time. After an hour I called and scheduled a technician to come and check it out. He came the next day, but my speeds were back to almost 10Mb again, and he couldn't find any problems.
I'm suffering with this annoying internet connection for a months. I'm using a router (tp-link) which I think the source of the problem ,yet I'm not sure. I'm a connected to the router via cable.My download speed is 10kps and below, we already contacted our ISP and change the cable yet the problem is still there.
I just had comcast internet installed, and am using a linksys wireless router (WRT160N). When I connect my netbook to the network it gets 0.7mbps on speedtest.net, when I use my girlfriends laptop it gets 16+mbps. I have tried everything, I am at my whits end. I have updated my firmware, updated windows to the the limit and reset the settings on my router. If I connect my netbook directly to the router I get 20+ but wireless is 0.7 and upload speed stays the same. I am using an HP Mini 210-2000 with windows 7 starter, I have updated it to service pack 1 and have all the windows based drivers installed. I have not tested it on another wireless network to see if it gets the same terrible connection. I don't know if its something with my computer, windows 7 starter, or the way my computer talks to the router
I'm having a big trouble with my internet connection. The Upload speed is extremely slow after i got a new mainboard, that problem appears.[code] I'm tired with my suck internet connection! Upload a 1MB photo to Facebook took me hours..This problem has started for a week.
I just recently purchased a Linksys WAG320N and replaced a setup with Linksys AM200 modem and a good ole Linksys WRT54GL. Problem is that after the switch i immediately got around 100 KB lower transfer speeds no matter what source i use or kind of transfer i perform. If i earlier got for example 860KB/sec i now only gets 760KB/sec.I´ve set the modem/router up pretty much using the default values, are there any settings i could change to get a more efficient use of my bandwidth? I am using the provided network cable that came with the WAG320N, but i have also tested with other cat 5 cables. The file transfers are taking place using cable attached devices only.
My E3200 is set up with no encyrption/ security. The 5GHZ band is set to wireless N, channel width is set to Auto (20 or 40) channel is also set to auto. I have my 2 laptops connected on the 5GHZ band and both have excellent connection with 300mbps. I'm transfering some files between the 2 and an only getting 7MB (so ~56mbps). Both laptops are running windows 7 ultimate.
I've tried transfering music, videos, and some ISO's.
I've some troubles connecting my PS3 to my RV120W.Both router and PS3 have latest firmwares. They are connected wireless (distance is about 10 mt, signal is good).PS3 ip is in DMZ (connection doesn't work with only Upnp), and ip fragmentation is enabled.Everything seems to work (NAT type 2), but downloading on PS3 is extremely slow. My ADSL is a 6Mb, download speed on PS3 seems like more than ten times lower (I don't know how to test it..). Plus, downloading a 100 MB patch is almost impossile, cause sooner or later I get an error and i have to restart.Two of my PCs are connected wireless, so I guess wi-fi is not the problem.
