Help me see if I'm thinking this through correctly, please...
Briefly, my setup is the DIR-882 handing out IP addresses within a certain range, some devices with static IPs so I can always access their management pages easily, and a DIR-615 running DD-WRT set up ages ago as a client bridge, on the same SSID, basically to connect to the 882 via wireless but then to connect my NAS via ethernet. I don't know if this still makes sense, but it's how I set it up ages ago and I'm afraid to change too much. And, YES - I know my tech is outdated, but it still works.
I just added a Firestick, however, and they recommend that you connect to 5GHz if you can. So I hoped I could designate that in the 882 *by client,* but you can't do that. I'd have to set up 2 separate SSIDs and, because I'd prefer that my primary devices (notebooks, iPhones) connect automatically, I was going to take the original SSID name (let's say it's MyNetwork) and make it the 5GHz SSID, and then call the 2.4GHz band MyNetwork-2.4.
That means I'll have to reconfigure all of my older devices (at least 6 of them: cameras, printer, NAS, husband's old iPod) to connect to MyNetwork-2.4. I'd have to know which are NOT connecting to MyNetwork, and manually reconfigure them all with that new SSID. And, because I'm pretty sure that the DIR-615 is 2.4GHz only, I'll also have to ensure that its SSID matches the 2.4GHz SSID... right?
I'm not sure it's worth the effort or risk to my tenuous setup, but is this the only way to ensure that newer devices connect to the faster band?
