If you've been having trouble getting a third-gen Apple TV connected to your Wi-Fi network, you might want to take it to your nearest Apple Store to be replaced. in a leaked memo obtained by 9 to 5 Mac, Apple admits that "a very small number" of the set-top boxes are having Wi-Fi connectivity issues, and is planning a "Wi-Fi connectivity replacement program" to trade them for working ones. If your device has a serial number ending in DRHN, you could be eligible for a free replacement box up to two years after the purchase of the original.

According to the document, Apple employees and service providers will need to test your box, and the third and fourth characters of the serial number must contain one of these pairs: 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.

Brand-new Apple TVs might not be affected by the issue at all. This year, Apple made a very minor change to the design of the set-top box, swapping out only "minor components." While one of those components was an A5 processor which consumes less electricity, the other was believed to be a new Wi-Fi module.
