I have an Apple Time Capsule and a Brother HL2170W printer. My printer worked fine with the time capsule for the longest time until last night it started acting up. I followed brother's online manual and temporarily use an ethernet and the printer works fine. However when I try and set up a wireless connection it never works. I am asked my network Authentication method and I chose WPA/WPA 2 since thats what my router uses. However for the encryption mode I am given choices of AES and TKIP. For neither of those does my printer connect with my router. I understand my router uses a ASCII encryption. Someone please help.
