WiFi simply isn't designed for the constant, high bandwidth, load of surveillance cameras.
This!

It's way more complicated than bandwidth. I have 3 wifi cameras, and they struggle even though I am running a Google mesh system with all ethernet backhauls. When I had an issue with my mesh, the cameras would drop out often, no reason - just Poof!! Gone for a minute or three and back. This even though the cameras take about 1% of the actual sustained throughput of my wifi system.

I have posted this before.

I did a WIFI test a while back with multiple 2MP cameras each camera was set to VBR, 15 FPS, 15 Iframe, 3072kbs, h.264. Using a wifi analyzer I selected the least busy channel (1,6,11) on the 2.4 GHZ band and set up a separate access point. With 3 cameras in direct line of sight of the AP about 25 feet away I was able to maintain a reasonable stable network with only intermittent signal drops from the cameras. Added a 4th camera and the network became totally unstable. Also add a lot of motion to the 3 cameras caused some more network instability. More data more instability.

The cameras are nearly continuously transmitting. So any lost packet causes a retry, which cause more traffic, which causes more lost packets.
WIFI does not have a flow control, or a token to transmit. So you devices transmit any time they want, more devices more collisions.

As a side note, it is very easy to jam a WIFI network. WIFI is fine for watching the bird feed but not for home surveillance and security.
The problem is like standing in a room, with multiple people talking to you at the same time about different subjects. You need to answer each person or they repeat the question.

For a 802.11G 2.4 GHZ WIFI network the Theoretical Speed is 54Mbps (6.7MBs) real word speed is nearer to 10-29Mbps (1.25-3.6 MBs) for a single channel

11G is ancient. While I only use it for laptops, phones and tablet, my Wifi at home is 802.11AX, I get 500Mbps INTERNET speeds on my phone using 5Ghz. speed test I just ran had zero packet loss, 20mS latency and sub 10mS jitter. I am using a pair of Ubiquiti U6-L4 access points, one at each end of the house, wired to the house gigE

I know there's a way. I'm really hating drilling into anything and my attic is tight. I'm 6'4"and close to 300 lbs. I physically can't do it and can only imagine what it would cost for a professional to run it.
take some preliminary pictures of the beginning, end, trouble areas of pulling a wire. There are wire pullers here (like myself) that may be able to make some magical suggestions!

It does not matter what your new fast network is. Most all camera are 802.11G 2.4 GHZ WIFI so that is as fast as you will go. The slow network has better wall penetration, and covers greater distances. There WIFI interface hardware in cameras is as cheap as they can build it.

ah, I was thinking of where you'd use a wifi P2P link to a cluster, with poe to several actual cameras at the remote end, rather than wifi to each individual camera.

I'd love to have a camera or two out near the end of my driveway but I have no way to get power or wire out there, so they'd have to be solar, which is a whole other can of worms, considering the number of tall trees lining said driveway. Well, never say never, but it would involve 200+ feet of trenching my driveway and parking area asphalt.

If there is a will, there is always a way.
