Reader Patrick O. recently wrote in asking, "Is there some way to extend the range of the guest feature of the AirPort Extreme N Dual Band models? I can extend the main network, but the guest network resists all efforts, and some online searches say it cannot be done."

Glenn replied, "Cannot be done, sorry. This is a limitation in how Apple has created the guest network, which is to create a virtual SSID, a kind of alternate but software-created network name."

Thanks to Patrick for asking, and I hope this blog post saves someone else from spending a lot of time hunting for a non-existent option.
