My old Linksys E4200 router has performed admirably for quite a few
years now, but may be getting a little long in the tooth. I've been
browsing routers for awhile now. Yesterday an ad for the Linksys AC2200
popped up in my inbox. It looks perfectly well-suited for my home
network (3 Win 10 PCs, two android tablets, HVAC system, 2 Windows
phones, network printers/scanners, Amazon TV, and of course internet
connectivity)...

The kicker is that it requires downloading an Android or iOS app in
order to set it up. We still use Lumia 950 Windows phones. Why would I
need Android or iOS to install a router which will be running a Windows
wi-fi network?

Second question - when I do decide on a router, will I need to
re-install all the peripherals or will the new router recognize the
current network and take over from there?

Thanks in advance for any enlightenment! -Walt

The app is to allow remote access to your router; i.e., you are away
from home and want to see what's happening or reconfigure your router
when not at the router. You might want to consider the security
ramifications of allowing remote (external) access to your router. Make
sure to change the default admin logon password after getting the
router.

As the instructions mention, you can setup the router using a wired
(Ethernet) connection from an intranet host to the router. With a wired
connection, you connect to the internal web server in the router.
