I have got hook a little bit on ebay so when I find something that I fell might be a steal that I could use I buy it. I purchased three wrt54gx4 linksys wireless routers for 21 dollars including shipping. They were as is sale stating that customer could not get them to work. I figure at least one would not need anything but firmware update so this would be worth the price. Well it turned out that two only needed firmware update and they worked great. The third did not have wireless with no wireless light even. I figure well I at least came out ahead. Tonight I took the screws loose from under the rubber on the bottom and removed the top and bottom. I then remove the tin cover from the bottom of the mainboard and there was the problem. There was a small board for the wireless that was not in the slot in the mainboard all the way. Pushed it in wireless worked. So if you ever have someone who has one of these routers and the wireless does not work have them follow these steps and in a lot of cases that will fix the problem. Not sure if other linksys routers use the same two board way of getting wireless but it they do then this also might work for them.
Just thought I would pass this along.
sorry about putting this under software should have been hardware next time I will open My eyes.
sure someone will move it.
