I was primarily using a Mikrotik hAP AC on 5GHz (mostly because of the security and frequent firmware/software [security] upgrades: of which, nothing is better, seriously, nothing), and a mix of re-purposed ad hoc collection of old routers-as-APs.
Back then, offline was frequent for some V3’s, less frequent for others, and I think a couple just never had issues.
Then …my baby bro’ bought a couple of TPLink Omada EAPxxx AP’s, and said I should look at them (to replace my ad-hoc collection) …simply because he liked the UI.
Hmm …FWIW, I should interject here that I’m a sys admin, and support several remote client offices a couple of states away? (BTW, I’d long since previously moved all the offices to various models of Mikrotiks for the frequent security upgrades.)
Anyways. Not only did I end up upgrading my entire AP mix to all TPLink Omada’s (mostly EAP 610s) and such, but mandated it for all the client offices, too. (The Omada line also has frequent security firmware & software upgrades, though less than the Mikrotiks.) Note: for remote offices, we also mandate a TP Link Omada OC200 hardware controller (which makes remote support a no-brainer).
Since we completed those WiFi upgrades a little over a year ago, we have had zip-zero-nada issues with WiFi in the client offices. Nor any complaints. None. Just sayin.
And, not entirely coincidentally, and pertinent to this thread. None of the V3’s have had a non-power related offline incident.
(I did notice the Pan V2 had an offline a few weeks …mostly notable due to not having seen one in so long lol.)
Note: as part of my personal network upgrade, I also replaced the hAP AC with a Mikrotik RB3011 (non-WiFi) router …because I got a really good deal on it lol.
Anyways. My anecdotal recommendation (to the more techie inclined), is for a minimum Mikrotik router - the RB2011 is pretty powerful for home use (if it’s a hAP ACx then TURN OFF the internal WiFi) - and as many TP Link EAP 610’s as needed for your inside coverage area, along with as many outdoor versions as needed there.
(I have a couple of EAP225’s, but while “looking up model names” while writing this reply, I just noticed they have a new EAP610-Outdoor offering …which I will surely be purchasing to replace an EAP225 or two …mostly because the EAP610 support WiFi6 at 1GB+ speeds. Yeah, measured WiFi speeds are typically higher than wire speeds “depending on local environmental conditions”. Who knew.)
Summary.
Replace your consumer grade router system with a prosumer small business class Mikrotik RB2011, and add as many EAP610’s as coverage dictates (that would typically be qty 2 for a 2500 sq ft ranch style house, and maybe a single EAP225 outdoor for, say, a 1/4 acre lot).
CAVEAT EMPTOR: If you’re not a techie, or don’t have access to a friendly networking techie, there is a fairly steep learning curve involved here. For both the Mikrotiks and the Omada HW. But. It. Will. Be. Worth. It …especially as regards Cam V3 connectivity reliability. (Security peace-of-mind should be the real reason to upgrade tho’. Just sayin’.)
Uh. This was meant as a reply to the poster asking for specific router/WiFi recommendations. But it seems to have moved to the main thread. Sorry. (Dunno how to fix that.)
