VPN Download Speed Slow

My effective download speed off most websites is 52+ KB/sec, which is acceptable.  However, my VPV connection effective download speed is 5-7 KB/sec. with my firewall and antivirus software shut off.  All other users, all using Win XP and braodband, have download speeds of 50+KB/Sec., some as high as 135 KB/Sec.

My connection config is:
Win 2k Client ->Cisco VPN Client v 4.0.03(F)->Westell 2100 WireSpeed Dual Connect Modem->Verizon DSL(ISP)->T1 connection (2Mb/sec -no up/down split)->Cisco PIX 501 firewall with VPN firmware v 6.3(3)

I made the following registry changes that did not help:

HKEY_LOCAL_MACHINE/system/currentcontrolset/control/class/ Cisco Systems VPN Adapter:
      DriverDesc, VAMaxMTU = 1000 (it was 1500)
      MaxFrameSize of type DWORD = 1000

Any suggestions?

The slow download speed is even with no other users using the VPN connection.

There is a SetMTU utility that comes with the Cisco VPN client when it is installed. Can you have a look to see what the interface is set to?
I think it is normally set to 1300 but you could try lowering it even furthur to around1200.

I tried lowering the MTU to 1200, 1100 & 1000 using SetMTU, but none of theose setting helped.  I wonder if the VAMaxMTU setting in the registry is related.  I had changed it from 1500 to 1000, but it did not help.

I was not able to ping the host after I made your suggested change, so I reinstalled the VPN client.  I noticed that this install I had to add NetBEUI manually.  I was able to ping the host after I added it.  Browsing and downloading files are still very slow.

Thanks,

Why are you using NetBEUI?
It is an old protocol that can only be used on your local network.
Perhaps you mean NetBIOS?
