I, like others here, have had the problems of cams and bulbs dropping off wifi besides a host of other problems. I was using a quality TP-Link router and extender and still had problems. I was reading an article concerning the number of items that we connect to our routers and that tends to cause a problem.
Because I have a boatload of cams, bulbs and other assorted items connected to my wifi, I decided to gamble on a Wifi 6 router. I purchased a TP-Link AX-6000 and used that by itself without the aid of the extender.
Holy cow. Now, realize that I am not trying to sell anyone on this, I am just reporting what worked for me. Once I had this set up and all of my Wyze products connected, I was amazed. My 3 outdoor cams which are the farthest away from the router connected with no problem and have stayed that way. Actually, all of my Wyze stuff has worked flawlessly since. I’m a happy guy.
I was just looking at that same TP-Link model. Glad to see this worked for someone before I bought it. 
Do you need to give the 2.4GHz channel a separate SSID for the Wyze cams to login ? Or just one name for all wifi channels ? Currently I am using a Netgear R7900P wifi router and have to name the 3 bands different SSIDs for the cams to pick up the 2.4GHz specifically. Thanks!
I have one SSID for the 2.4 GHz band and another SSID for the 5 GHz one. I put 2.4 and 5 in the names to distinguish between the two.
Great tip @RZRguy
I just want to be clear here so that others with limited wireless networking knowledge can understand what is going on.
WYZE devices (and most IOT devices for that matter) run on the following WiFi - 802.11 b/g/n 2.4GHz (does not support 5GHz network).
What this means is that WiFi 6 does not work with WYZE IOT devices. (General Terminology: WiFi 6 = 802.11ax, WiFi 5 = 802.11ac, WYZE = 802.11 b/g/n 2.4GHz). (i.e. it is not the WiFi 6 making WYZE devices work better)
What @RZRguy points out is that the equipment providing your WiFi network (Gateway, Access Points, MESH, etc.) is the most important part (hub of the network wheel) of your smart home installation.
The cheap equipment your Internet company gave you or that you purchased for $16 on ebay will cause you more headaches than money saved. Quality equipment will support the latest standards as well as be backward compatible (with correct setup) to maximize the performance and function of all connected devices.
If you are going to build a smart home full of WiFi devices, in an area that may be congested with other WiFi signals (apartment, condo, etc.), you need to have good networking equipment or your installation will not meet your expectations. You get what you pay for.
My suggestions (home installation):
If you know what you are doing and want to be technically involved, use ASUS gear for your home.
If you want a simple to set up, MESH system that can grow and expand with little technical knowledge, get an EERO MESH system (I have not tried the ASUS MESH system).
**FYI - TP LINK (as many manufacturers) has had some critical password vulnerability issues in the past (2019). As with all devices, make sure you are following best practices and keeping your firmware up to date.
Hope this helps someone - JM2C
I have been running a wifi 6 mesh system for months with no issues with my Wyze products. It’s been great.
What mesh system are you using? Recently I bought a TP-link deco x60 from Costco when it was on sale. It worked awhile for my many v2 and couple v3. Then shortly afterwards either streaming is very slow or cannot connect at all. In the end I factory reset my 1.5 year old Netgear R7900p since the 2.4Ghz channel is full and cannot add new v3. And I avoid all my phones, tablets, smart tv etc from using the 2.4Ghz channel and preserve it only for active Wyze devices. Bought a Tp-link AX11000 router from Costco when it was on sale but haven’t tried it yet. I believe this router will work for my Wyze devices since it can have different SSID names for the 2.4Ghz and 5Ghz channels .
Wifi 6 AX also covers 2.4 Ghz and extends range of 2.4 Ghz as well as speed, but is also backward compatible. Please search on Wikipedia for 2.4 GHz (802.11b/g/n/ax).
I experienced a similar issue. I pre-ordered 5 Wyze V3 cams, but currently am using Canary cameras. At the end of September I noticed my cameras dropping off line frequently and they eventually stopped connecting completely. At first I thought it was a bad firmware update, and after much back and forth with Canary, determined that wasn’t the issue. The cable modem was brand new, purchased in July, so that was fine. Then I began running speed tests on phones and tablets connected to the WIFI and found the network was much slower than the speed I was paying for. Thinking back, my cable company provided router was installed over two years ago, and probably was a refurnished older model when they installed it. I researched wifi6 routers and decided to spend a few bucks at Bestbuy knowing I could return it if it didn’t help.
I was blown away at the results. Not only did all my old Canary camera reconnect to the network, they haven’t dropped offline a single time since I bought the new router in early December. The new router also has a far greater range than the old one. Our house is two stories plus a basement and we have no issues whatsoever with range, speed or connections. I purchased the ASUS AX5400 Dual Band (RT-AX82U). The quick start guide helped immensely and set-up was a breeze for someone with minimal computer knowledge.
wifi6 is the bomb! Very much looking forward to the arrival of my v3 cameras. FedEx should be delivering them tomorrow!
I’m running the Asus Zenwifi
I used to use two Asus RT-AC5300 routers in mesh mode. They worked flawlessly with 14 Wyze cams, along with 10 Ring cameras.
Since then, I’ve updated my entire network. Now using a pfSense appliance, 3 Grandstream GWN7660 access points (WiFi 6) in wireless mesh configuration. I’ve created 6 SSIDs, and 4 VLANs. IoT, Media, Main, & Guest. Segments being in separate broadcast domains provide for both security and performance.
I have posted a bunch of information about TP-Link mesh network and sporadic issues I had with streaming my cameras. ultimately ,I ended up changing to the ASUS ZenWiFi AX (XT8) and have not experienced any issues since. Went from 3 nodes to 2 nodes. Coverage and performance is great and handles the load quite well. I have 17 Camera’s including Doorbells connected, HMS with a bunch of Sensors, Door locks, Bulbs, Strips, Vacuum and Plugs. All connected and running great.
@R.Good has a TP-Link Router which works well for him, but it is not a Mesh Router, I believe.
My TP-Link Deco X60 are not in the closet collecting Dust 
Does anyone have experience with the NETGEAR MK63-100NAR Nighthawk Home Mesh WiFi6 System? Looking at a refurbished system on eBay at a reasonable price. Don’t want to waste my time if others have had poor results with them.
Sorry, I don’t.
I bought the Deco X60 3000 and had trouble connecting Wyze cameras and a doorbell. Nothing would connect. I repeatedly reset and scanned the QR code. The cameras would error out saying the wifi password was incorrect, when it was not.
In frustration, I left one camera in the “trying to connect” process after it errored out. A few days later I checked on the Deco app and discovered that something named “IEEE” had connected. It was the camera I left in the connect process! Knowing this, I was able to get all of the other devices connected and functioning normally.
Simply do not shut down the phone app. Let the device stay in the “trying to connect” process after it errors out and eventually the device will connect. I hope this helps!
