Hello everyone! I use the ASUS RT-AX55 router and have encountered the following problem with the 5G network: my iPhone X is not working stably with the 5Ghz frequency. The speed does not rise above 100-150 Mbps, although my channel is 1 Gbps. However, if I reboot the phone, the speed on Speedtest immediately becomes around 500-600 Mbps. After some time, this situation repeats. I also have a second phone - the Samsung Galaxy A54, which does not see the 5Ghz network at all. The firmware version of my router is 126.96.36.199.386_52041.
