Can 802.11a connect or can bridge to 802.11n? I do search the internet but it doesn't gave me a clear idea. I also searched in this site, but I saw, b to n, or ac to n.
I'm an amateur in this kind of field. TIA for someone who would like to answer/help! :)
You'll have to make sure that both APs support 802.11a. 802.11n is a technology supported on both WiFi frequency bands, so it does not indicate which band you are on. If AP1 supports only .11a and AP2 only .11b/g/n, it will not work, as both APs will be on different frequency bands. For example, your first research probably lead you to "b to gn" and "ac to an".
Consumer-side, the 2.4GHz is represented by 802.11b/g/n, and the 5GHz by 802.11a/n/ac. There is other WiFi standards but it is not relevant to the answer.
Yes, if it has the WiFi logo on the box. WiFi Alliance makes sure devices are backward compatible.
Wi-Fi CERTIFIED n products work with older Wi-Fi devices, including 802.11 a/b/g, and Wi-Fi CERTIFIED ac. Wi-Fi CERTIFIED n products have the very latest generation of security protections, WPA2™ (Wi-Fi Protected Access®), so certified products offer the highest level of protection.
