For example, an older range extender that supports WEP and WPA will not be able to boost a WPA2-encrypted signal from a router. Security encryption compatibility also matters and must be at the same level of compatibility for the signal to be extended. 802.11ac equipment is backward compatible with 802.11n, 802.11g, or 802.11b equipment.Īn older range extender will not be able to repeat the signal of a newer generation router. 802.11ac is the most recent and third-generation Wi-Fi standard for wireless home networking. However, 802.11ac runs at 5 GHz and requires an access point capable of 5 GHz operation. Most 802.11 compliant devices are backward compatible. There are wireless range extending devices that conform to all 802.11 protocols. Some wifi range extenders have an ethernet port to also provide a wired connection. With those repeaters, you can still use your wall socket while using the repeater. Some wireless repeaters have a power outlet. USB supports not only the data transfers required for networking, but it also supplies a power source so that these adapters do not require electrical plugs. These USB adapters add Wi-Fi capability to desktop PCs and other devices that have standard USB ports. Some wireless range extending devices connect via a USB port. Older devices don't always support WPA2, so while the original network might be secure, the secondary one is potentially open.įurthermore, the quality of the connection to an extender is generally worse than if connected to the host access point.
