I am searching for a solution to an issue I occasionally experience. This includes my Linksys WRT54G router will just stop working for wireless clients.
Wired connections work just fine and have no issues. The wireless... no so good.
I am able to quickly power cycling the router without a problem. The wireless then just starts working once the router comes up.
This happens with the Linksys firmware or the DD-WRT firmware I am running now.
BTW - if you have a Linksys router (or any other supported hardware) and are not running DD-WRT, you need to (HAVE TO) check out the DD-WRT project for your basic home router software needs.
