My AXE7800 was bought 18 months ago. It worked fine for the first few months. After that the 6GHz signal disappeared and I assumed that it was the problem of my only 6E device which is a Samsung S23 Plus because it was right after upgrading to Android 15 and some users encountered similar problems. When Android 15 came to S23 Plus a few weeks ago, most S23 Plus users said that the problem has gone, and the cell phone can connect with Wifi 6E but mine still cannot. I factory reset my AXE7800 and the 6E signal appeared again and I could connect my S23 Plus to the router. However, the 6E signal disappears again after I rebooted the router and never come back again. Is this a problem that only happens to me? Any similar issues out there? I don't want to keep factory resetting it for the 6GHz signal.
