Loose WEP key every day or two. - DirecTV

My directv dvr continues to loose it's WEP key after a day or two. My WEP is a hex number. I have replaced the DTV box and I have removed all special characters from the SSID. Am at a lost why I continue to loose wireless connection and have to add the WEP key in every day or two.
