Cisco WAN :: ASA5510 - DMZ To INSIDE Extremely Slow File Copying
May 9, 2013
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?

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).

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

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'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'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.

So recently my wireless speed on my desktop had dropped considerably. I have a 3Mb/s connection, but I am getting speeds ranging from 0.2-0.5Mb/s in speed tests(Actual Mega bits, not Bytes). Last week I set a static IP so that I could do some port forwarding. I don't exactly remember what day I did the static IP, and what day it started going slow, but this is my prime suspect. All of the other computers on the network are running at full steam. I even changed the settings on my wireless adapter back to obtain IP/DNS automatically, but the problem still persists.
I am using a TP-Link wireless USB adapter with up-to-date drivers. [URL]. I already had the ports forwarded in my router. I reformatted my PC a few weeks back and finally got around to setting the static IP again. The forwards were saved already in the router, I just set the IP to the one I had used before.

Slow browser speed on all browsers, but the downloading and uploading speed are normal according to speedtest.net. Ping is a bit high. Other computers in the house are fine.Already contacted ISP (Time Warner), modem is not the problem Contacted Linksys router support, router is fine. anti virus plus malware byte.

On certain downloads, Wifi speed seems to be throttled to about 100kB/s. I see this mostly on two BlackBerry Z10s, but also just saw it on my Wifi-connected PC when trying to download the latest DIR-655 firmware. The Z10s are screaming fast on Wifi at my work. They also do fine on YouTube and any other high bandwidth applications (I just tried Speedtest and got 11Mb/s). I think I can say that the slow speed is only when I'm downloading apps or updates on the phones.
I just updated my DIR-655 to the latest FW and have spent an hour flicking settings trying to find something that makes a difference. No luck. As it stands now, I'm downloading the latest OS upgrade to BB10 (345MB) at 100kB/s.

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.

We are having several issues with the new batch of RV016 (rebranded as cisco and with cisco firmware. The Cisco RV016’s are configured to load balance aDSL internet access from 4 Cisco 877 modems/routers. Ports used are WAN1, WAN2, WAN3, WAN4.
Issues are: WAN 1 port resets to 0.0.0.0 regularly and traffic on WAN 1 fails DNS fails regularly behind the RV016 onlyIntermittent internet connection behind the RV016Slow internet connection behind the RV016Extremely slow DNS query and reply behind the RV016 (DNS resolve takes 1min -1m30)
The issues above are reported from different deployment sites and with different scenarios.
We also test above with Code...

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'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.

I have a year-old Sony Vaio laptop which connected to the internet without any problems on my BT Homehub connection. However, I recently moved in with my girlfriend who has a Virgin media connection and, although I can connect to it without problems, it is extremely slow (around 0.30 mbps) whereas my girlfriend's laptop is fine (9.74 mbps), we both have iPhones which are also fine therefore I'm pretty certain the problem lies with my laptop. I have tried updating the wireless card's drivers (windows tells me they are up to date) and I've also tried disabling my Norton 360 but it didn't make any difference.

For a few days now, my internet has been as the title suggests. A speed test has shown my download and upload speeds to be about 0.06 mbps each. Every once in a while, I try a diagnose and repair, and occasionally I get one of either "Reset your TCP/IP settings" or "Improve your TCP/IP performance", but neither works. I've tried resetting my modem and have done a system restore to no avail. Offline performance is good, RAM is in good shape, etc. AVG hasn't found any viruses or spyware. It's an ethernet cable, by the way.

I got a new Netgear N600 Router and installed. Everything works fine, except my PC, which is using a Belkin F5D8055 V2 USB adapter. My upload speeds are less than 1Mbps, while on my net book, ipad, and iphone they are 5Mbps+. I can not firgue out how to fix this. I am running Windows 7 Home Premium, SP1. My PC has an I7-920, 18GB RAM, and 2x Radeon 5870.

Would a slow ping, but a fast download rate cause extremely slow streaming? for example 140 ping with a 13.1 Mb/s per the speedtest net test.

I have an Asus RT_N12 that works great(12-20mbps) hardwired. It also has a "excellent" connection when connected wirelessly but slows down to 50Kbps.I have restarted/started, reset(all multiple times). I contacted ASUS customer support they told me bad router or firmware update. I updated firmware same thing took the router back and exchanged router. Same problem. I then went into router settings and changed from "Auto" to channel,1,2,3,4,etc. No luck. My buddy that is a "Tech expert" says that since I live in high density(12 unit) apt building someone has something interfering.My only problem with that is I used to live in a 48 unit building with wi fi supplied by the building and never had this problem.

I am using Comcast as an ISP and have a standalone Arris modem. I, obviously, have a DIR-655 router REV B with a firmware revision on 2.00NA. I have already turned off packet shaping and QOS. Also, I have set the firewall settings to Endpoint Independent for both TCP and UDP, and assigned static IP addresses to my computers. The problem I am having is that whenever I go to any secure websites, i.e. anything that starts with https, it takes an extraordinary long time to log in and to navigate to any webpages therein. I also cannot upload photos to a website and when I try the Speed-test.net website the download speed is OK but the upload test errors out, it doesn't connect.

A while ago I had to take my laptop in to have it formatted and reinstalled after I had picked up a virus. I use the internal modem behind the battery where you insert the card, if I insert an external dongle using the same sim card it seems to work just fine. Before the reinstall it was just fine, connection speed was great 3g etc, now it is slower than an old 56k dial up (no kidding) I have asked the company where I bought it, but they cant find the problem. Is there a setting or update etc that I need?

I have recently purchased a new Dell XPS 8500 desktop computer (running Windows 7) to replace my old Dell XPS 420 that died.
I have set up the internet connection on the new computer, however the Ethernet connection is painfully slow. Most webpages take forever to load, that is if they load at all. However, when I use my laptop on wireless, the speed is fine so there is no problem with the network - it must be an issue with the computer.
The laptop also works fine when connected via Ethernet.
Is there something hidden away in Internet settings that could be the cause of the slow speed, or could I just have a dodgy network card? I could easily buy a network card as there are empty slots to install. The computer will be under warranty, but would probably be easier to buy a network card for a few dollars and install myself rather than have someone come out.
I ran the Bigpond ADSL installation disk to install the relevant drivers and configure the settings automatically. I use a T-Gateway TG797n v3.

I have a problem concerning my Netgear XET1001 85 MBit/s Wall-Plugged Ethernet Adapter. My personal computer in my room is connected directly to our router and I'm getting arround 14-15Mbps download speeds. My parents computer is located in a different room and I bought them the Netgear Adapter thinking this was the most effective and simplest solution. Better than a Wifi-Adapter. I cost me quite a lot too to be honest. The problem is my parents are getting speeds of 0.05Mbps and the browser often doesn't even load the pages completely. To me it seems like the data can only travel through the thing very hardly if at all.
We thought this might have to do with the age and RAM of our computer. (512MB of RAM) So we bought a new one a couple of days ago. Turns out: nothing has changed.
The Wall-Pluggs are connected directly to the outlet by the way. I'm trying to give you the most amount of information I can think of so one more thing might be important. Yesterday I brought my parent's PC into my room, connected it to the Wall-Plugg and got speeds of 5Mbps. Although this is better, it's not what I bought this thing for. Even a WIFI connection would be faster would'nt it?
