VPN problems with wireless router & Microsoft MN-720 network adapter

Discussion in 'Wireless Networking' started by Mike Christie, Feb 19, 2005.

  1. I have a Linksys WRT54G wireless router. I have a laptop running
    Windows 2000 and use a Microsoft MN-720 802.11g wireless network
    adapter. I use 128-bit WEP encryption. When I connect directly to the
    internet everything works fine. However, when I use my company's VPN
    software to connect to my company internally I have intermittent Web
    access problems. Everything else works fine: Microsoft Exchange email,
    connection to network drives, instant messaging, Microsoft Netmeeting,
    etc.

    With Web access, sometimes everything works fine. Sometimes I can
    connect to my company's intranet, but not to the internet. Sometimes
    the opposite is true. Sometimes when I first start a VPN session,
    everything is fine, but after a while I lose either the internet or
    intranet. Often closing and restarting my VPN session will restore
    access. I can find no rhyme or reason to access or lack thereof.

    What is strange is that yesterday, out of extreme frustration, I
    disconnected the wireless, grabbed an Ethernet cable and plugged my
    laptop directly into the router. After that I had no problems at all
    with either intranet or internet connections.

    Is there a wireless setting on the router I should change?

    If the connectivity problems affect Web browsing only, my prime suspect
    would be the browser configuration for Web proxies. Try verious manual
    settings for your ISP/your corporate proxy, see if you'll achieve stable
    behaviour.

    I reckon the problems you have are notrelated to wireless connectivity.
