The model in question is the third generation Apple TV, which is the most recent one. An internal Apple memo has been leaked by 9to5mac, wherein Apple confirms that “a very small number” of third-gen Apple TVs are affected by this Wi-Fi connectivity issue.
The Cupertino company is planning to launch a “Wi-Fi connectivity replacement program” whereby customers with an affected box can simply take it into an Apple store and receive a replacement.
The document dictates that a selection of devices will be eligible for the replacement program, with the serial number being key to knowing whether your Apple TV can be replaced or not. The third and fourth characters in the serial number need to contain one of the following pairs in order to be eligible;
H9, HC, HD, HF, HG, HH, HJ, HK, HL, HM, HN, HP, HQ, HR, HT, HV, HW, HX, J1, J2, J3, J4, J5, J6, J7, J8, J9.
You can check the serial number of your Apple TV on the side of the box it came packaged in, or on the side of the device itself. If you’re experiencing Wi-Fi troubles with it and your serial number matches one of the character pairs above then get in touch with Apple or pop it in to your local Apple store.
