5 Ghz WiFi Issue

So I'm having an odd issue that really has just started to happen lately. First of all the router I am using is an tp-link ARCHER AX3000. My 2.4 Ghz network is fine on all my devices in the house Apple or not. My 5Ghz non Apple devices are fine too. However on both my iPhone and MacBook Air I will have full signal but my internet just stops working, only way to fix it on either device is to turn the Wi-Fi off and back on. So I'm thinking this has to be some sort of issue between Apple and my router on the 5 Ghz Network side. Since I'm only having an issue with my Apple products on the 5 Ghz and everything else is fine.

Any suggestions? Maybe an more Apple friendly 5 Ghz router setting?

Sorry for the delay but I was busy last night digging around and changing some settings. I did change the channel on my 5 GHz to 136 and so far my iPhone and MacBook Air haven’t been losing connections. I ran the Macs built in Wi-Fi analyzer and it recommended that channel for me and honestly so far so good. Hoping it holds! Thanks for the help.

A little update on this, I continued to have issues. I actually ended up hard resetting my router and starting over, everything seems fine now. My internet is working great now and my devices are good now too.

How about you tell us what are your current 5 GHz radio settings on the router:

Channel
Channel Width (20, 40, 80, or 120 MHz)
Wireless Security type (WPA, WPA2, WPA3). If WPA2, is it configured for TKIP or AES?

When your notebook is connected to the 5 GHz radio, what the values for:

Security
Channel
RSSI
Noise
Tx Rate
PHY Mode
MCS Index
NSS

Although not as common as the 2.4GHz band, there is still a possibility of Wi-Fi interference on the 5GHz one as well. Just changing the channel may have just resolved it for you.

I'm not that Wi-Fi tech savvy so I'm glad that it seems to be that fixed the issue. I also made a channel change and bandwidth change to my 2.4 GHz since I saw online some recommendations for that as well. Sometimes my smart plugs were slow or would lose connection as well on the lower band and that seems to have fixed that too. So I'm all good now just a couple of tweaks and all seems fine now!
