I have been using my DIR-655 with no problems for a short period now. I have a windows vista laptop that has been connecting wirelessly with no problem. The the other night the wireless went out. I hadn't changed any settings. The indicator light is no longer on the unit itself. I can not find the signal when I have the computer search for it. I went to the router setup page and found that under the DEVICE INFO that the wireless radio states "init failed". I can't figure out how to get this running again. I am connected via hardline cable right now. I have not upgraded the firmware yet. I am currently at 1.02. I'm a relative novice. I know just enough to get myself in trouble.
