Hi there and welcome
What happens when you do not power the Linksys on and off everyday?
And what have you tried to do to fix this?
Ok, you mean it does not connect to the wireless network anymore? Or it remains connected but no internet?
You will need to do a reset of the Linksys then set it up again to reload the firmware as this is the most common cause (a corrupted firmware).
On the back of the Linksys is a reset button. Using a paperclip, hold the reset button in for 10 seconds then release.
Wait 5 minutes then setup the Linksys again like when you first received it.
No need to worry about Mac Cloning though.
Then tell me how it functions please.
No, as your reinstalling it from the Rom, which is why I gave you these instructions.
Reply here when you know the results please, just post a message like you are doing now.
