Via Vista Horizons we get the following info about some network routers and Vista issues:
Some old network routers might not be compatible with some of Windows Vista's new networking features. Microsoft has issued knowledge base article kb932134
In short, Vista has a new networking stack that provides for increased traffic and IPv6 technologies that older routers can't handle. If you want to use these features, you may be able to upgrade your router firmware if the router is fairly new or you may just have to get a new router.
The symptoms of incompatibility are:
- Page errors occur when you surf the Internet.
- Network performance is reduced.
- The network router may stop functioning, and you must reset the router.
Updated firmware for popular routers can be found via these links:
In my case, the old LinkSys wireless router 54G, which I purchased over 3 years ago worked just fine immediately. I did go and upgrade the firmware just to keep it up with changes since many issues are always resoled with a router firmware upgrade - not just Vista compatibility.
