I switched my router over from the stock firmware to DD-WRT and now the two Fire HD 8 tablets and 3 Fire TV sticks I have can only see the 2.4Ghz wifi but they cannot connect to it, they get "authentication error" after about 30 seconds. None of them can see either of the 5Ghz networks either, which they could all see and connect to before changing.
I also have a Fire TV Stick 4K and a Fire HD 10 which can see all the networks fine and connect to all. All other devices I have, Macbook Pro, iPhone's, Chromebook, consoles, etc... can also all see all networks and connect ok.
Does anyone know if there are settings that need changing to allow these Amazon devices to see the wifi and connect?
I'm very new to this, so I'm not sure what the dhd driver is or how to change it. Would going back to the "latest release" version, 40559, be the best solution overall? I'm not particularly looking for any specific feature, I just want the router to work better than it did on the stock firmware, with which I had lots of speed issues and stalling connections, which I've not had since changing to dd-wrt.
So, after trying several different versions of dd-wrt and lots and lots of different settings, I spoke with a friend who suggested trying FreshTomato instead of dd-wrt and that worked for me "out-of-the-box" with no issues with any devices. It's a little sad as I think dd-wrt has some better features, but FreshTomato has everything I need. It fixes the speed issues as well as fixes various other issues I had with the stock firmware, so I'll stick with that.
