I currently have 6 cameras that have been struggling to connect to my network. I am using a tp link mesh system. The tp link allows for a “guest network “, so I repurposed it as a camera network. I went in and assigned static ip addresses to each camera and it’s been working substantially better.
The new network has its own ID and password.
Am running Wize Cam Floodlight v2, Wize Cam Floodlight v3, (2) Wize Cam v4, (2) Wize Cam v3
My cams are also all on an IOT (guest type) network with DHCP reservations (what I’m assuming you mean by static IPs here). They worked fine in my case without reserved IPs, I just like to organize my network.
With TP Link, often using a guest network will disable some of the features that can give these cams trouble, like band steering/smart connect, etc. So if you set the guest network up for 2.4ghz only, that’s likely what actually made things work better.
Having the cams isolated on their own network is a good idea (same for any IOT stuff). I have 5 VLANs and 3 wireless SSIDs on my network, but my setup is a bit overkill.
TP Link is a good value and I’ve set a few people up with them, however some of their more advanced stuff can be a bit buggy. I disable smart connect when I set them up for people - you can simulate basically the same thing by just giving both bands the same name and password, but it won’t try to “steer” clients to other bands, and it usually opens up some more options for tweaking too.
