I have some hardware that runs horribly on 5GHz, so I need to 'force' a 2.4GHz. But we will be using hotspots that are 5GHz, so we need a router to 'convert' this from 5GHz to 2.4GHz. So we will create a hotspot on the router, and use a hotspot at the same time. Ethernet also needs to be available on the router for LAN access.
I'm looking for 'modern' routers, and ideally good in price. But if that's not allowed on this site (it's saying "The question you're asking appears subjective and is likely to be closed"), just any routers work. I can do the look up for price. But ideally, someone knows a good off the shelf router.
Ideally I don't have to install something like DD-RWT, but if that's actually really useful then I can install it.
I just need to be able to connect to a provided access point only outputting at 5GHz, and then output a 2.4GHz connection.
Thanks for any help.
