Has anyone noticed a drop in 5GHZ signal strength on 21.02 vs 19.07.8 (TPLINK Archer C7 V4) ? Performance near the router was normal but very poor at the out lying edges of my house .
I had to revert back to 19.07.8 .
I have no details so when I go back to 21.02 what info should I be gathering/looking at in order to figure out my issue ?
I installed 20.02.1 and ran iwinfo and here are the results
wlan0 ESSID: "ollie5"
Access Point: 50:C7:BF:DE:51:7B
Mode: Master Channel: 36 (5.180 GHz)
Center Channel 1: 42 2: unknown
Tx-Power: 20 dBm Link Quality: 57/70
Signal: -53 dBm Noise: -103 dBm
Bit Rate: 212.0 MBit/s
Encryption: WPA2 PSK (CCMP)
Type: nl80211 HW Mode(s): 802.11nac
Hardware: 168C:003C 0000:0000 [Qualcomm Atheros QCA9880]
TX power offset: none
Frequency offset: none
Supports VAPs: yes PHY name: phy0
These numbers differ considerably from 19.07.8
wlan0 ESSID: "ollie5"

I'm not sure what the fix for this might be
So why is the transmit power being set down to 20 on 21.02 ?
Is this a bug ?
Is there anyway for me to force it back to 23 ? I tied adding option 'txpower' '23' to the config file and it did nothing .
I found this info for this device's wireless
· CE EIRP: <20dBm(2.4GHz), <23dBm(5GHz)
· FCC Transmit Power: <30dBm(2.4GHz & 5GHz
So the issue as was pointed out to me by user craz was all I needed to do was set the country code to US . Never had to do this before but thats OK
