I have the exact same issue & reported it several months ago. The only way I have to "fix" it is to periodically reformat the SD Card when it gets nearly FULL. Then it works fine for a week or so. Then I just Reformat it.

Mine was resolved by just moving my Router a little closer to the camera. And I mean by like 10 feet. It made all the difference.

Update: I have been working (via Email) with REO Tech support over the last few days. We confirmed that my issue was due to my ROUTER being too far away from the camera -- resulting in a very Weak WiFi signal. I moved our Router a little bit closer (as close as I currently can) and suddenly I am able to LOGIN and get LIVE VIEW without any interruption. So my next step is to see if I can move the Router even closer .. otherwise I will need to run a long ETHERNET cable; which I wasn't prepared to do.

Side note: the Camera is advertised as being WiFi capable 250 Feet -- "IN OPEN CONDITIONS" ... which of course, if Router is inside House, there are Walls that the signal must go thru.

Otherwise, this camera is very very nice image quality.

When this thing works, the image quality is GREAT. However I am having constant problems access the APP on both my Windows Client & my Android App. I get CONNECTION FAILED (Android) or LOGIN TIMEOUT (Windows) after launching the apps. I reboot the Camera (power reset) & suddenly it will work great as long as I keep the APP up and active. I close either APP and I can't get back in. I just let my Android APP Active and it constantly tries to connect ... (Connecting ... Connection Failed .. Connecting .. Connection failed.. etc.) The Camera is mounted just 50 feet away from the Router. I confirmed that It connects to the Router via 5G. After a successful connection/login, I get upwards of 500kbs speed to access the camera.

This thing is so BUGGY. Is TECH SUPPORT actually LOOKING at this Forum? Are there any plans for a FIRMWARE update? Kind of useless if I can't use it for what it is meant to do -- WiFi Camera.

Installed 7.2.2.7 after receiving our new RLC-411WS ... This PC Client software is horrific. For the following reasons:

My configuration: I have a Laptop, Android Smartphone, and the Camera all on the same home network router, using WiFi. (It is impractical for me to run 100' of Ethernet to direct connect the camera.)

- Immediately after launching the Client on my PC (windows 10), the Login constantly TIMEOUTs, even when my Laptop/PC is next to my Router
- What is the point of "TOUR" -- and setting it only at 5 mins? (no documentation in the Manual that I can find) How is this different than "LIVE" ?
- I go to LIVE VIEW at Launch of client, and it lasts as LIVE for like 5 seconds then freezes
- Non of the "Queries" work due to the instability of the Connection (Timeouts, etc.) - all I get are Blank screens the majority of the time, with the "Query Failed" at the bottom.
- Screens in the Manual do not represent all of the screens in the actual CLIENT installed
- Many other issues but I'll leave it there as a start

Side note: The Android App does the LIVE VIEW feature really well. The Time stamp compared to actual time is only a couple of seconds different, unlike the PC Client that is perpetually OFF by a minute or more, when it actually works.

Honestly, the DAYTIME STILL Images from this camera are awesome. But video Playback is very very "jerky" for some reason. Really 30 FPS ???

I really hope your Technical Group is working on a serious fix for the major flaws in this Client software. Otherwise it's kind of useless, IMHO.

Thanks for listening.

I just got the RLC423ws camera to replace the front of the house camera that was an Arlo. I am very pissed that this camera is having so manyh problems. I can access the camera only through the iphone app, I can’t log into the camera through the computer client software unless it’s plug into the router via cable. when I switch it to wifi and unplug the cable there’s no access through the computer, and only on the Iphone app. I can’t log into the camera on anything else because it says there’s a password and username error. I am about ready to send this hunk of crap back to Reolink, and leave a bad reviews about this junk all over the internet. FIX YOUR SOFTWARE, AND GET US BASED CUSTOMER SERVICE OR A US BASED 800 NUMBER!!

I am having the exact same issue. I can access LIVE via my Android App, but using the (latest version) PC Client, it constantly struggles getting a LOGIN ... it Times Out, or when it finally DOES connect, the LIVE camera lags behind and just STOPS .. I really struggle trying to modify SETTINGS - it often disconnects before a successful "Query" completes. I bought this to use via WiFi -- I do NOT have the ability/desire to run a 100' Ethernet cable. (And yes - a US Based 800 number would be a great benefit for many of us. Seems like Reolink is based out of Hong Kong.)
