Cisco VPN :: 5540 Slow Downloads When Using VPN Clients
Jul 22, 2012
We have had a shift in our work force and find a large number of uses now working from home. Lately (this weekend) they have been complaining about VPN client downloads being very slow. I have tested the IPSec client and the SSL client and compared them to an Internet download on the network using the exact same laptop and the exact same web site www.speednet.net. Here at the office I see 50M, over both VPN's I see (if I am lucky) 1M, all reading within a 15 minute period and all over the same 600M pipe to the Internet
We have never noticed this before this work force shift to home. Eliminating all other factors, which we think we have, would you expect VPN clients to behave this way?
MTU is set at default from day one. The only thing we have done to VPN configuration over the last week was to add a tunnel gateway to the ASA 5540 VPN configuration which is only a hop away from the firewall inside interface.
I will provide configuration data if you request but my question is just a general one at this point. Is this normal and can you make a suggestion as to how we can improve? We are research, running wireshark on the test laptop so as the day progresses we will have more information to provide if needed.

I used to get speeds that exceeded 2 mb/s and now when i download steam games it fluctuates from 0 kb/s to 2.1 mb/s in an oscillating pattern. What is wrong with my internet? games that should take less than an hour to install now take 3.

i recently done a clean install of windows xp on this laptop after having vista on there for a couple of years and ever since doing this the download speeds have seemed so much slower im not sure weather its got to do with the OS or weather its just the internet has been slow since ive installed it. Im using wireless connection to connect to my router also.

I ran a speed test with my new DIR-655 connected to my PS3 and my download is 768kbps and my upload is 1.5mbps. However, my internet connection is 50mbps and 2mbps upload on my computer connected via LAN. While I understand SOME decrease, that's slower than the previous Wireless G router that I had.
I've reset the router twice and it's currently set to the factory defaults. I've even tried setting a static ip address for the PS3 and put it into DMZ mode. However, I'm still getting the slow speeds.
Also, my iPhone 4 is getting about 14mbps download and 2mbps upload. Is that expected?

I have one customer who is complaining about slow FTP sessions, and timeouts. Depending on the file size, it gets to about 98% down and hangs. The ASA has a CSC SSM-10 on it, and even bypassing FTP through it, the problem occurs. It is running 822-17-k8 OS. Turning the SSM off does not make any difference.

I just built a new computer with most of the bells and whistles. Asus P8Z77-V pro motherboard, Intel I7 3770K CPU, NVIDIA GTX 560TI, SSD for my boot drive, HDD for storage both running on SATA III, 16 GB of RAMMy problem is that when I connect to the internet via an ethernet cord, my download speeds are about 58 MBPS which is fine but upload speeds are only about .3 mbps. I have changed cables 3 times and connected directly to the modem rather than the router which would indicate an ISP issue. The kicker is that when I disable the LAN network and enable my wireless network, I get slower download speeds as expected but my upload speeds are closer to 5 MBPS, more than 10X times faster which throws my ISP theory out the window a bit.

I have decent Bandwidth, high download speeds (25.67mbps) low ping(16ms) And okay upload speeds (4.47mbps). I usually browse Reddit and my father usually plays CoD. The problem is, whenever I try and download anything, his game slows down to where he gets kicked from the room.

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 recently switched to cable with Comcast. I am getting 20+Mbps wired, but I only get 1 Mbps w/wireless download. I am getting 4+ upload via wireless. Is my set up wrong? I reset my modem and Internet worked fine without any other changes. I am planning on buying a modem (instead of leasing) should I buy a gateway? I didn't think this router was out dated yet.

I have a Cisco 871w that has been a very great product for many years. I recently switched to Windows 7 x64 on my main machine and now i am having all sorts of issues with it.. I have done a bit of research and found that it appears that it might be the firewall on the SDM that is causing the slowness issues. what does happen is that downloads from known good sites will run really slow. If i hook up my Macbook Pro or my Windows XP laptop i have no issues at all. i have tried Disabling IPv6 as well as SMB2.0 and this has not resulted in a fix at this point.

i have a 4Mbps DSL internet connection with 3 PCs connected through a router. 2 are connected wirelessly and the other is wired via an ethernet cable. i noticed that when downloading a file from an international server, the transfer rate on the wireless PCs is 2-3 times slower than on the wired PC. the wireless PC would get about 150-200kb/s, whereas the wired PC can max out to 450kb/s on a single download. however when i download from a local or nearby server instead, the transfer rate on the wireless and wired PCs are the same and can both reach up to 450kb/s per download. i don't understand why the wireless connection is slower to international servers compared to the wired PC.my wireless signal is at 54Mbps with "excellent" strength. i also tested the ping results from both the wireless and wired PCs to international servers and they are pretty much the same.
- all PCs are running windows XP SP3
- the modem/router is a D-Link 2640B

I'm having a throughput problem with a new ASA 5540 running version 8.2 (1). When trying to access a database server using tcp port 1521 (sqlnet) it is about 10 to 20 times slower than when the database is not behind the firewall. We've been running the same software on a database behind an ASA 5520 running version 8.0 (3) with no problems for years. When I check the cpu usage on the 5540 at the ASDM home page, it is rarely above 20% and never above 30% while this is being tested. I tried testing ftp throughput over the same interface and it was normal with ~320 Mbps average rate transferring a 500 MB file.

We have ASA 5540. We setup Site-to-Site VPN and Remote Access VPN (Cisco VPN client). If are running full tunnel on the Cisco VPN client, the internet access is slow. For example, when we are running full-tunnel, the internet speed is 16 Mbps based on Speedtest.net. When we go to Speedtest.net, some of the graphics do not load. If we are running Split-tunnel, the internet access speed is 78 Mbps based on Speedtest.net and the Speedtest.net web site loads all the graphics.

I have an WRVS4400N configured as a WAN and Wireless router and can connect clients (PC's and laptops) wirelessly thru out the office. The clients that are farther away (10-15 meters and on another floor) connect at a very slow rate i.e. less than 10MBps. I have a WAP4410N configured as a repeater. Immediately after powering up it will allow connections to the 4400 and clients work fine for a 1-2 minutes, then the connections drop and I can no longer connect through the 4410. Nor can I ping the 4410 through the 4400 although right after the pwr cycle I am able to ping the 4410. After another pwr cycle the 4410 is available for another short period.I have attached some info on the configuration of the units and I also have the configuration files available.

We currently have an ASA 5520 communicating with 10 ASA 5510's, all on static outside addresses. I was asked to add 5 additional 5510's on dynamic address. All worked well in testing until it was decided that some of the dynamic clients needed to talk to each other.
My testing shows packets just dying in the 5520.

I have 4 desktops cat5 to Dlink DIR 615 router. All work fine. Any wireless clients, laptop or netbooks, see the desktop computers for a while then disconnect somehow. All machines can see the Internet through the router at all times. The desktops disappear from the laptop/netbooks but the wireless machines can be seen from the desktop computers but clicking on them gets 'Access Denied' message after a wait.3 desktops = XP, 1 98SE. All laptop/netbooks = XP

I have a Netgear WNDR4500 running the stock firmware, acting as a router for my home. I also have 2 routers that are flashed with DD-WRT (Linksys WRT54G and Asus WL-520GU) running as client bridges. The Netgear is 192.168.1.1 and the other 2 client bridges are 192.168.1.2 and 192.168.10.3. The Netgear router is performing DHCP giving addresses from 192.168.10.100 to 192.168.10.254. I have numerous machines connected to the Netgear, wirelessly and wired, and numerous machines wired to each client bridge. All machines have IP addresses that are 192.168.10.100, 192.168.10.101, 192.168.10.102, etc... Everything is working fine, but I have one question: When I access the Netgear router, it shows the client bridges as clients, machines that are wired and wireless to the Netgear router are listed as clients, but the client list does not show any clients that are connected to the client bridges. I assumed that since the router is performing DHCP that all clients would show up.

Very recently whenever I download a file which is in a package e.g. a rar file or an iso it always seems to be corrupt. For example I downloaded the windows 8 consumer preview multiple times and each time was corrupt. Now I know it isn't anything to do with my computer as I have this problem on all devices connected to my internet including my ps3, every game I download is corrupt and I cannot install it. I've tried all the obvious things like turning the router on and off and plugging the device directly into the router via ethernet

I recently switched providers and now i'm down to a 1.5 MBPS download speed (advertised at 3 MBPS but our area is only serviced for half that) so I'm trying to find something that will smooth out the capabilities of my PC's with streaming videos and such for my nephew on sites like disney.com and other sites. I can post specs later if you guys need em but one PC which I know its issue, it is around 10 years old so I'm not expecting great performance. The knew one though is only a year old with 1GB DDR2 Ram and windows XP Home. The older one has 512MB Ram....I think its SD with windows XP pro. Again I can post full stats later if needed but not really trying to trouble shoot. More looking to boost. We run 2 computers and a Wii off our wireless modem. I'm curious if somehow the computers could be configured to operate on seperate...ports I guess to minimize the lag on the modem. We are noticing that if one computer is downloading something it cause the second computer to lag or makes streaming anything all but impossible.

I have an RVS4000 with FTP download issues. I have the latest v1.3.3.5 software and the latest ISP (1.5). Regardless of any settings changes, my FTP downloads always timeout. I have tried a new basic router and had no issues, so it is not the PC, FTP software, or the ISP. I have even put my PC into the DMZ and still no resolution.

Running into a bit of a problem. Anytime I try to download a large file through our 5510 the download fails at different points. Cannot download via a download manger at all. I see nothing in the logs which are set to infomational.
I can connect my laptop to our internet connection outside the firewall and HTTP and download manager downloads connect and finish just fine. I go through and scrub my config for posting?

I have two computers, both of them running Windows 7. One of them has been experiencing an odd problem for about six months now, and now that school is out I have time to mess with it. When I try to do certain things, the download speed periodically drops to zero. Specifically, I've noticed it when using Firefox and Steam, but also for IE and a few other browsers I installed for the sake of testing. I know I'm not *losing* connectivity, because everything that isn't specifically downloading a file works fine. Skype calls work fine, Utorrent streams at a steady rate, but for some reason Steam and Firefox have speed graphs that look like the heart rate monitor of someone with a very weak pulse. It starts off strong, a nice solid 1 MB per second, and then after 10-30 seconds it'll slowly decline to 0, and sit there for anywhere from 10 seconds to half an hour before picking up to full speed again. I've tried reinstalling drivers, I've tried buying a new network card, I've tried running antivirus scans, and I've tried uninstalling my antiviruses. The only thing that works for sure is putting it into safe mode. In safe mode, the downloads proceed smoothly. I tried making a list of everything that ran in safe mode, and then rebooted into normal mode and closed each nonessential process and service, but that didn't work either.

I have an odd problem where http downloads will stop after a few seconds. I can stream video, do anything else with the internet perfectly. It's just when downloading files from websites will this happen.I use a wired connection. I have tried Firefox, Chrome, and IE10, and this problem happens in all of them. I use a WRT54GS router. I have tried downloading files in Ubuntu 12.10, Windows 7 using wireless, and WinXP, and they all can download files perfectly. Only Windows 8 seems to have this problem. Another thing is that my Windows 8 is a fresh install.I have also tried disabling Windows Firewall to no avail.
