58u is good up to around 15-20ft of solid wifi performance. @ 30 feet, the speed drops significantly. A high quality 4x4 AC router is better at this distance.
Im using a RT-AX58U right now as I write this and the router is on the second floor and I’m approximately 30 ft. away. I’ve got full isp speeds and a -60db signal on the 5ghz band. I also have a RT-AX88U and the 58U range and performance is pretty close to the AX88U. If you have a AX58U and it can’t throw a strong signal 30 ft. it’s defective.
