I've had several clients looking for wireless adapters for Apple computers and they are almost impossible to find. It would be great for Best Buy to consider stocking the Edmimax AC1200 Wireless Dual-Band USB Adapter (EW-7822UAC) and/or AC450 Wi-Fi USB Adapter-11ac Upgrade for MacBook (EW-7711MAC) and stock them in the Apple accessory area.
While all new Macs have built-in WiFi, older Macs sometimes will have WiFi issues that prevent them from connecting to newer routers, some older Macs just plain didn't come with WiFi card unless you addded them (in the case of older Mac Pros) or sometimes the WiFi cards just go out and there's no practical solution to externally fixing this. Outside of technical isuses, if Best Buy employees were trained on these items, they could be sold as ways to upgrade older Macs from 802.11n to 802.11ac not only giving clients access to better speeds and better range, but also generating demand and revenue from the sell of Wireless 802.11ac routers that clients would want to buy to achieve these speeds/ranges.
Would anyone else like to see us carry these wireless adapters for Apple computers? Make sure you vote for an idea if you like it.
