Unknown, nobody properly tests this anymore. Personally, I feel like most high-end routers should have fairly similar range. These newer models have a new wifi SoC, they may possibly be slightly better. Whether it can be shown in day-to-date usage or only in a synthetic benchmark, that's the real question however.Well I'm mostly interested in Wireless range coverage. Are they the same in that department? Will they give better range than say the RT-AX88U or AX86U?
