Latest test result: if a WPA4220 is using an IP address, and a DHCP server assigns that address to some other device, the WPA4220 abandons the address and uses its algorithm to choose another. So...

That technique worked for me for a while; but eventually something caused my multiple WPA4220s to stop using their preferred IP addresses, and they all picked random IPs. You can not set a "fixed" IP...

No, since the factory default IP address i(192.168.1.1) is just a preferred IP address, not a fixed IP address. If multiple WPA4220s are connected with the same preferred IP address, most with...

There is actually no way to set a "fixed IP address" on the WPA4220. You can only set "preferred" IP address, which the device will use first when looking for a suitable IP address. But if the device...

Update. The WPA4220 has a non standard method of assigning itself an IP address. Here is my guess as to how it works. First it monitors the network to which it is connected to determine a possible IP...

For how long did it work like a charm? The TPLink device has most certainly self-assigned itself another IP address, which will work until some other device is assigned that IP address. It might take...
