All N wifi routers also do B/G wifi automatically unless you lock it on N only mode in the settings.

CURRENT PROJECTS Retired couple (retired electrical contractor) 100% hardwired both security w cameras & network Tech couple w teens (chip design mgr) wireless security, 100% network no cameras + 7 extra conduit runs Tech couple under 30 (design & finance) hardwired security, 9 camera runs, full network w several repeater points SECURITY NOTES At the point we will remove security prewire from our proposal templates as the big wireless providers have installed in 3 of last 4 completions, and 1 of 2 in process. Each of the wireless installs required visible to the eye white sensors on all exterior doors which some might find surprising and tacky in custom homes Typical wireless contact install. The lower photo is an 84" x 120" entry pair for scale. What bothered me most is the salesperson told the client they would use the prewired contacts and prewire to control pads he had just installed and paid for. An hour later the install mgr made flimsy excuses why they couldn't (but was able to use in a prior build). Client paid $1600 to the wireless company. NETWORK Home uses a hardwire camera system hardwired network w repeaters. All clients are set up to work from home using their cell phones, so high quality wireless network is also critical. MISC "Smart" aftermarket doorbells w cameras don't connect the same as typical door bell buttons. Typically the units need an internet provider installed, up and running and the transformers in the doorbell system need to be modified, replaced, etc. Cryptic translated install instructions. Similar with some smart thermostats.

I'd like to be able to turn the lights in an outbuilding on and off from the house, as well, of course as in the outbuilding. I'd like a simple on/off switch (no dimmer) that I could install in the house, wired to power, so no batteries to mess with, that will work on its own, without any kind of home automation hub. It would be great if it could look (and work) like an ordinary toggle switch. The switch location in the outbuilding is about 150 ft from where I'd like to put the switch in the house. There's good WIFI signal in both places. RF would be fine if the range is adequate. Does such a beast exist that works relaibly? I'm finding much more complicated systems and a bunch with pretty mixed reviews. Thanks!

@wdcruise Thank you for your help so far! The issue is that he, for some reason, can not access above the wall/from the attic down into the wall. There is something preventing the wires from being fed down the wall to a switch. Of course, I would not mind the drywall cut out for the addition of a switch. But, it is the wires from the switch into the attic and powersource that is the issue - they can not feed them down the normal way. The only way would be to cut from the attic down, to see why the wires will not feed, and then try to correct that. They have already wired power to the pendant light. I just need a remote way to switch that power on/off.
