slow vpn connection over wan

April 24, 2009 at 00:34:40
Specs: Windows XP, 344
In our network (w2k3 domain, and xp workstations) connecting with vpn to the internet is just very slow. Especially loading the the default intranet home page takes much time!

Here`s the scenerio:

- The VPN software client is Cisco VPN client
- Workstations are all XP
- The VPN access server is in Australia, while the branch office is in Tokyo also the INTRANET server is in Tokyo
- The wireless network/data card is Fujitsu AH-F401U

Here`s the problem:

With this wireless connection, when a user initializes either internet or intranet connection, it takes as much as 2 minutes and 30 seconds (2:30sec) for the INTRANET site (default home page) to fully open.
On the other hand with direct LAN (via LAN cable) connection, it takes just about 0.5 seconds to open up the same INTRANET site.
I`ve tried all sorts of work arounds with no success. Including changing the BTU size, and various other twick-settings in the VPN connection, and Wireless NIC connection`s property settings.

Specifically what we want to achieve here is to reduce the time it takes for this INTRANET site to fully load.
Anyone gone through this before? Any solution please?

So if I'm reading your post correctly:

- When connecting wirelessly over the VPN from one site to another, it's very slow

- When connecting via a wired connection over the VPN from one site to another, it's fast.

correct?

If this is correct, then it's pretty obvious the issue would be the wireless network. If the problem is your wireless, there may very well be nothing you can do about it. Wireless is subject to a lot of issue that slow it down compared to wired connections which is one of the many reasons I'm not a fan of wireless. It's insecure, it's subject to latency and lag issues that you don't get with wired, it's slower and well, you pay for the convenience of it by having to put up with all the aforementioned issues.

Including changing the BTU size, and various other twick-settings in the VPN connection, and Wireless NIC connection`s property settings.

I'm thinking you meant MTU as a "BTU" is a "british thermal unit" and is a measure of how much heat is produced by something like a heater.

Get rid of the wireless.

"Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, are in my top 10
