Have connected to my network previously and had no trouble. Suddenly it doesn't want to connect. It sees my network but because I have already used it, it does not prompt for security key, it just tells me to troubleshoot. Have tried many thing but just can't get it to connect. This all happened after I connected my tivo wirelessly

Try what is mentioned: 1- Check if you've got a static IP address. If yes, it may be in conflit with another one. Son change it and check if your problem is solved or not. 2-Delete all the registed wireless networks and check if your problem is solved or not. 3- Re-install the wireless card driver and check if your problem is solved or not. If all what I mentioned changed nothing, try to restore your system state from a restore point and check if your problem is solved or not. Best regards.

Thank you so much for your kind reply. Yes I had tried all the above with no luck. Stubborn old me did not want to reset my modem though. After doing so, problem solved.
