VPN works for one wifi adapter but not another one
Posted on 2010-08-31
I am in an area where I subscribe to a local community wifi service. I have a Dell laptop computer with an internal Dell Wireless 1390 WLAN Mini-Card. I am on the fringe of the service area and the signal strength and quality are not very good. I can successfully establish a VPN connection to my remote work office network using Cisco VPN client. Once the connection is established, I can ping any of the computers at the remote office network.
I purchased a Realtek RTL8187 Wireless 802.11b/g 54Mbps USB 2.0 Network Adapter because I am on the fringe area of my community wifi service and I get a much stronger and better quality signal using this adapter. I can successfully establish a VPN connection to my remote work office network using Cisco VPN client. However, once the connection is established, I CANNOT ping any of the computers at the remote office network.
So the VPN connection works correctly when using my laptop computer's internal wifi adapter, but not with the RealTek USB wifi adapter. By the way, I have tried establishing VPN connections sponging off another unsecured wifi access point and the same thing happens. The VPN connection works for my Dell internal wifi adapter, but not the Realtek USB wifi adapter.
I am running Windows XP and McAfee Personal Firewall.
Your task is to provide a solution that will cause the VPN connection via the RealTek USB wifi adapter to work correctly (so I can ping the computers at my remote office network).
