If you currently have 2.4GHz cordless phones, replace them with models that use the 5GHz or 900MHz spectrum band. Get New Phones Swap your cordless phones or baby monitors for new ones that use another band. The procedure for updating older versions of Bluetooth varies by device check the manual. Bluetooth devices using those versions avoid hopping onto frequencies that are in use. Update Your Bluetooth Make sure all your Bluetooth equipment is using version 1.2 or later. Does your Wi-Fi connection stutter or fail when you’re talking on your cordless phone? Is your Bluetooth keyboard missing keystrokes? Do your cordless phones produce static when the Wi-Fi network is busy? If so, you need to do something about those devices. This frequency hopping can degrade Wi-Fi networks.Īssuming you’ve ruled out other Wi-Fi networks as the cause of your AirPort woes, these other devices are your next suspects. Instead, they hop from one channel to another in a preset pattern. (Though 802.11n can use 40MHz channels for faster transmission, Apple has chosen to allow that only in the 5GHz band.) Bluetooth equipment, cordless phones, and other devices use channels that are a few megahertz wide, but they don’t stay on them continuously. Wi-Fi devices stake out subsets of the spectrum available in each band, using 20MHz channels of the 85MHz available in the 2.4GHz band, or of the 550MHz available in the 5GHz band in the United States. But these and similar devices don’t transmit data the same way as your AirPort hardware, and that can also cause interference. All of Apple’s Core 2 Duo laptops and iMacs (except the discontinued 17-inch 1.87GHz model) can also use the 5GHz band with the build-to-order wireless option, so can the Mac Pro.Ĭordless phones and Bluetooth devices use the 2.4GHz band, too. The newest AirPort Extreme Base Station is one of the few Wi-Fi base stations designed for home use that work in that 5GHz band. Use the 5GHz BandĜompared with the 2.4GHz band, the 5GHz band is practically empty. ![]() Netgear, and other networking vendors make power-line hardware. You then plug another power-line adapter into an outlet near an interference-free spot somewhere else in the house, place your base station there, and run an Ethernet cable from that adapter to your base station’s WAN port. You can run an Ethernet cable from your broadband modem’s LAN port to a power-line adapter plugged into a nearby electrical outlet. ![]() You could move the plug, but doing so would require an expensive service call to your cable or phone company if you’re a renter or if the plug is located on a stone or brick wall, moving it might be impossible.īut there’s another alternative: home power-line networking, which carries data across a home’s electrical wiring. But this can be tricky if your AirPort base station has to connect to the broadband feed coming into the house and that feed happens to enter at a particularly interference-prone spot. Move the Base Station If interference is particularly bad in one part of your house or office, move the base station to another location.
