I will try to do a factory reset to see if that solves the problem Coming Soon when i have the time,I mean the second problem from the bottom

  @Liverpool20 

I fixed it in 2 ways when I logged out of the admin panel and reconnected quite strange or did a factory reset and I hope I don't have this problem again

i don't use iphone only samsung about changing the wireless security from WPA3 to WPA2 I I haven't changed anything, it has the same factory settings again quite strange

The problem is Firmware from my experience this router requires an update to be as stable as possible unfortunately those from tp link do not offer monthly updates,from what I've seen, they provide updates when they remember or get bored

before I had an ax50 eu v1, after almost 2 years they made a pathetic update and this model is quite poorly made

at 05.01 AM in the morning I took a quick picture on the phone when the 5ghz was not working

Screen 1:

I quickly checked the wifi network with my phone and the band 2.4GHz it went without any problem but the band 5GHz did not appear

Screen 2:

When I woke up the next morning same problem 09:20 AM but after a few seconds I think it connected to the band 5GHz clearly the firmware is not stable and needs an update

Screen 3:

if there is another similar topic with problems of this kind, it should be posted in this topic I already posted the problems I found,this router has strange moments when it doesn't work properly from my experience Firmware it is still at the beginning and has not received a serious update because of this, strange problems also appear

if many users don't keep this topic in the top, I can't do it alone

question is ? when will those from tp link start to focus on this model as well ? no one knows as always

Hello unfortunately, I cannot monitor this router model 24/7 to see how it behaves,all I can do when strange problems arise to post them,

System Log View a detailed record of system activities. I think I posted these files twice I don't know if it helps but they are posted

  @Kevin_Z 

hello and sorry for replying late, I just got home from work currently both bands were set to manual they are no longer set to auto,I think that when they are set to auto, this strange problem appears this is what I believe,but the problem appears only on the 5ghz band 

well my sister has 1 iphone 11 but me and my parents i use samsung A8 4g,A71 4G and A53 5G when the problem occurs on the 5ghz band it crashes on all phones the strange part is the 2.4 ghz band has no problems at all with samsung j3 and samsung j6 old model

I have a gaming laptop that is not connected to wifi I have it on the normal cable UTP CAT 6 connected  because I play games online and I need all the power on the internet

2.4GHz Channel manual 3 and 5GHz Channel manual 40 Well, the channels that use them are not crowded the program I use is netspot

I deleted the password so that it is not visible in the picture the settings are from the factory, I have never changed them [WPA2-PSK, AES.]
