My Doorbell V2 has been working flawlessly since I bought it in December 2025. All of a sudden recently the signal became unstable. The mechanical doorbell still works, it records doorbell rings, and sometimes motion. I can see the live feed but only for a few seconds then it would freeze. I see the time stamp would update about every 5 to 10 seconds. Settings get erased no matter how many times I set it. Sometimes when I open the app I can see the doorbell is offline until I click the button. Then it would take a while to connect. I troubleshot with Wyze support and we completed all troubleshooting steps to no avail. Wyze ended up sending me a new device. After installing the new device, the issue remains. Nothing have changed with my WiFi and power to the doorbell. The only thing I can think of is some kind of interference from outside. I would also like to add that I have 5 other Wyze cameras connected to my 2.4 GHz WiFi and they are all fine. Need assistance thank you.
Welcome to the Forum, @Flipsonic! 
What detail can you share about your doorbell’s transformer? Specifically, I’m curious about its rated output (in AC Volts and Volt-Amperes) and the voltage you’re measuring at the Video Doorbell v2’s installation location.
Well the doorbell is connected via 2 wires (white & red) from the wall outside the by the door. It has always been connected the same way since it was installed 5 months ago and it worked just fine. Nothing has changed. It worked with the mechanical doorbell in the house. My house was built in 2003 so voltage should be fine. But I can check that.
Just checked. It is 16.7 V at the doorbell.
I would do that to see if you can rule out power as a possible contributor to this problem for a couple of reasons:
- I don’t believe Wyze Support ever asked me about this when I went through troubleshooting with them after developing chime problems with my Video Doorbell v2. They replaced my Video Doorbell v2, but then I did some additional independent troubleshooting that revealed my home’s built-in mechanical chime had been wired incorrectly before I moved into this house: The wire from the transformer had originally been connected to my chime’s FRONT terminal, and the wire from the doorbell button location was connected to the chime’s TRANS terminal. That difference is practically irrelevant when a simple “dumb” doorbell button is being used, but when you install Video Doorbell v2 and Chime Controller into the system, it’s important to have all the connections be accurate and correct.
- I’ve seen some Forum users report performance problems with their Wyze video doorbells and then later discover that they’re using an under-powered transformer (like 10 V AC, 5 VA).
Thanks for checking! 
That seems low to me, and it’s at the low end of what Wyze recommends:
I’ll rephrase one of my original thoughts: What is the rated output of the doorbell transformer you’re currently using? If you can find the transformer, then this information should be stamped or embossed somewhere on the transformer’s housing. As a point of comparison, my transformer is rated 16 V, 10 VA, and I have consistently seen in excess of 18 V AC when measuring with a digital multimeter at both the transformer and the doorbell button’s wiring location.
At this point I’m wondering if you should replace the transformer, but before doing that I’d want to know if the transformer you have is supposed to be compatible (i.e., meet the minimum specs Wyze advises) and if it’s correctly wired to the chime (i.e., the FRONT [or whichever] and TRANS terminals had the correct wires in place before you started).
But as I said, it has been working just fine since I installed in December 2025. It was installed according to the (2 wire) wiring diagram from the installation instructions. So you think the voltage at the transformer degraded when the problem started?
No. I don’t yet have enough data to make that determination, which is why I’m saying that I’d want to know what the transformer’s actual specs are if I was investigating something like this in my own home. It could be like you speculated:
It could be power. I don’t know at this point, so I’m trying to eliminate power and wiring as possible issues.
My Video Doorbell v2 worked fine for months after installation…until it didn’t, and I didn’t change anything that caused the chime actuation issues. That’s when I went through the rigmarole with Wyze Support when they had me go through their scripted troubleshooting and then eventually sent me a replacement. That’s also when I did my own tracing and discovered that the transformer and doorbell button wires were on the wrong terminals before I ever installed my Video Doorbell v2 and Chime Controller.
Why did my Video Doorbell v2 and chime work for months and months and then stop? I have no idea. What I do know is that correcting the wiring to the chime resolved my problem, so that replacement unit Wyze sent me is sitting in its box as a spare. 
I probably should’ve mentioned this earlier: 
I am not an electrician.
Right, but did you do any testing at the time to ensure that your baseline wiring and transformer rating and output were all correct and adequate?
I didn’t check the voltage when I installed it because it worked just fine. If it wasn’t working, I would’ve troubleshot further. I guess I can look at the doorbell to see what the specs are. I haven’t looked since I first installed the doorbell. Thanks.
Are you doing continuous recording to microSD? If so, then that’s something else you could check, as gaps in the timeline might indicate a power issue rather than a problem with the Wi-Fi signal.
I have fixed the problem. It’s definitely not a power issue. It is related to signal whether it is weak or interference. I connected a wifi extender and placed it close to the doorbell cam. That made the signal on the cam from 2 to 3 bars. I think it was due to interference because it had 2 bars before and was working fine. My other 5 cams in the house have 2 bars as well and are working fine. I noticed my neighbor has an EV charging station at his driveway. Not sure if it has been there for a while but that is the only possible source I can see right now. In any case, the problem is fixed. Thanks for all your help.
I’m glad you were able to find a solution. Thank you for taking the time to post an update!
Well after just a few days, the unstable signal is back. I confirmed the Wi-Fi extender i still online so I don’t know what the issue is this time. This is frustrating.
I feel your frustration, especially since Wi-Fi connectivity issues can be tricky to troubleshoot. That’s another reason I suggest investigating the power:
- If you can determine that there is a power issue and solve that, then that may resolve the connectivity problem.
- If you determine that power is sufficient and can be ruled out as a cause of the problem, then you know you can shift focus to the Wi-Fi itself.
- If you ignore power as a possible contributor to the problem and start doing things to your Wi-Fi, then you could still potentially have an issue with power but not be aware of it.
It might not be a power thing in your case, but that’s something I’d want to rule in or out, because those kinds of issues are often more straightforward than troubleshooting the Wi-Fi.
Having said all that, I commented on my own use of a range extender in another topic earlier today:
I don’t know what kind of range extender you’re using or how you have it configured, but if you have mixed-mode WPA3/WPA2 enabled for security, then I’d try setting it to WPA2 only to see if that improves your performance. If you have easy access to your doorbell’s transformer and can see its rating and measure its voltage at the transformer, then I’d still do that, too.
I submitted the logs to Wyze support. They said it’s not a power issue and looks to be a signal issue. They suggested that I move my gateway closer to the doorbell. I can’t do that as my Xfinity XB8 gateway is on the 2nd floor and the coax cable isn’t long enough. That’s why I used the Wi-Fi extender. It is on wpa2 security, same Wi-Fi as the other 5 Wyze camera. These cameras are older than the doorbell camera and they all have stable signal. Why would signal on the doorbell be stable for a few days right after I added the Wi-Fi extender then back to unstable again? Could it be another bad camera? I’m really scratching my head on this one.
If it’s one of Xfinity’s xFi Pods, then I don’t have any experience with those, but I believe my brother-in-law experienced flaky performance when using them in his home. He eventually got tired of paying Comcast’s equipment rental and had me help him set up his own cable modem and router (plus mesh attached to the router) and has had better network performance since doing that.
It’s also possible that—whatever extender you’re using—the Video Doorbell v2 is trying to connect to your gateway’s Wi-Fi signal rather than the extender’s signal if you don’t have the doorbell bound to the extender (i.e., forcing the doorbell to use the extender as its access point rather than being allowed to “roam” to the gateway). That might be more of an issue if you have the extender and gateway using the same SSID (which is what I did when I was using an extender, because I wanted to be able to roam without creating a secondary SSID). If you haven’t already done so, then you could possibly try giving the extender a unique SSID and then re-initiate device setup on the Video Doorbell v2 with this new SSID as the Wi-Fi source.
Could be. If you bought it from Wyze and set it up just a few months ago, then Support may offer to replace it. They might have you go through a few troubleshooting hoops first. Since they’ve already replaced one for you and you’re experiencing the same problems, then I’m guessing it’s somewhere on your end.
Thanks for the suggestions. Unfortunately, I can’t name the xfi Pod to something different than my gateway ssid since it is a mesh network using band steering. You might be correct that the doorbell may be connecting to the gateway and not the pod. I have to look in to that. But why would the pod work for a few days only after I added it? Flaky pod? Also why would the signal only to the doorbell degrade when nothing has been changed? It’s not like I moved anything around. As I said my other 5 Wyze cams are unaffected.
I don’t know, and my experience with those xFi Pods is limited to assisting family with those, as I haven’t had any myself. I’m still curious about this:
Yes, continuous recording with sd card. I do see gaps but I thought that was due to the unstable signal. I ruled out the power issue since the doorbell worked for a few days after I connected the pod. I’m beginning to think I may have a flakey pod and this is a signal issue. But again, my other cams are unaffected.
If the timeline isn’t showing a solid green recording stripe, then I would interpret that as interruptions to microSD recording. I would expect microSD recording to continue even if the device loses its Wi-Fi signal if the wireless connection itself was the only issue here, because all that microSD recording is local to the device. Whether or not the device has a constant Wi-Fi signal should not affect microSD card recording, or at least that’s my understanding.
As a test, I blocked my Video Doorbell v2’s access to my Wi-Fi network for 5 minutes, and during that time I was unable to view its live stream. The device also failed to return pings that entire time. Once I restored the device’s access to my Wi-Fi network, it began returning pings again. When I went to check the microSD card recording timeline (it’s set for Continuous recording), there was no gap or interruption of the green stripe for the time that the device was blocked on my network, so microSD recording continued even though the device’s Wi-Fi access was interrupted.
That’s not the inference I would draw based on what you’ve described so far.
That could be. Like I said, my brother-in-law’s experience with those wasn’t entirely satisfactory.
If it’s a power issue, would I see a constant 16.7 v when I have the meter probes touching the terminals on the doorbell? I’ll definitely look in to the power issue. Thanks.
