Using my mesh WAP’s management webpage there was a definite difference over signal strength from V2’s to V3’s anywhere from 2-5 dB difference was seen with cameras being in same exact location.
Many others have posted about the V3 being weaker in the WiFi compared to the V2.
All my cameras are on a very stable power system so that is not an issue for me.
