Vista vpn slow

I check out the code to a shared directory on my PC. Wednesday, July 18, AM. I wish microsoft would fix the problem instead of forcing us to buy 3rd party solutions though. Monday, July 30, PM. Hi Jennifer, Yes.

I work for Dynamsoft. I had the same problem over my LAN connection. Thursday, September 6, PM. Hi Nicola, Thanks for the input. Contents show. Pale Moon. Maxthon 5. Slim Browser. Comodo IceDragon. UR Browser. Every one of these failed xp install.

May want to append this article to Windows 7 and above. Please enter your comment! Please enter your name here. You have entered an incorrect email address! Thus, only when I used Remote Desktop was it slow. It was very odd, because from my Vista PC I could connect to many other machines with no problems.

After doing some more research I discovered that Remote Desktop 6. Receive Window Auto-Tuning continually determines the optimal receive window size by measuring the bandwidth-delay product and the application retrieve rate, and adjusts the maximum receive window size based on changing network conditions.

Receive Window Auto-Tuning has a number of benefits. It automatically determines the optimal receive window size on a per-connection basis.

And IT administrators no longer need to manually configure a TCP receive window size for specific computers. For typical client-based networking traffic such as Web pages or e-mail, the Web server or e-mail server will be able to send more TCP data more quickly to the client computer, resulting in an overall increase in network performance. The higher the BDP and application retrieve rate for the connection, the better the performance increase.

The impact on the network is that a stream of TCP data packets that would normally be sent out at a lower, measured pace, are sent much faster resulting in a larger spike of network utilization during the data transfer. For Windows XP and Windows Vista-based computers performing the same data transfer over a long, fat pipe, the same amount of data is transferred. However, the data transfer for the Windows Vista-based client computer is faster due to the larger receive window size and the server's ability to fill the pipe from the server to the client.

With your VPN connection active on your laptop, however, everything you download to your home laptop has to first be uploaded to you by your office VPN. This means that everything sent from the office over the VPN to your laptop has a maximum throughput of the office upload speed. Also consider that all remote users share this upload speed, so the speed you can achieve depends on how many people are using it. To do this we can open a command prompt and use the route and tracert commands.

Tracert is a command that lets you display the route and transit times of packets in a connection. For simplicity, the discussion below lists the IPv4 addresses, but when you run these utilities yourself you will also see the IPv6 values. In this configuration, the home laptop has no access to the office network, so all traffic goes through the home router, which has a gateway IP address of Running route print produces two interfaces and shows the gateway IP address.

A gateway value of On-link means that the client can connect directly, without routing. Running tracert verifies the route goes through the home gateway at address Now we connect to the office VPN. By default, windows makes the VPN interface the default gateway instead of using the home router as the default gateway. Running route print shows the new VPN interface number There is now also an On-link route for the interface at If only there was a way to route just the office specific traffic to the VPN, and everything else through your home ISP service.

That should solve our slow network woes. To do this, we will use a static route. A static route is an entry in the routing table that is manually configured, as opposed to entries that are automatically determined. You can add a static route to your laptop so that only traffic specific to This is very simple to do, and you can make it temporary just to test it out. We will discuss how to create a static route in the next section, but for demonstration purposes we will show the routing table and trace route when a static route is added for the office LAN address range of The route print command now shows an additional route for the As you can see in the first few entries, instead of using the office VPN as the gateway, we are now using our home network router!

Any replies to web page requests or file downloads will run at the speed of our home ISP, rather than be constrained by the upload speed of the office VPN. The result is that all office LAN traffic will go through the static route gateway, and all other traffic outside the home LAN will go through the home router gateway.
