Hi,
Newbie here, so gently please
New Raspberry Pi 4 2GB. Bought with Piaware SD install. Netgear Orbi Router home network works a treat with everything else.
Raspi repeatedly drops wifi randomly with “carrier lost”. Maximum connection is about 1 hour. Minimum 10 secs.
iwconfig gives
lo no wireless extensions.
wlan0 IEEE 802.11 ESSID:“Wi-Fi Network”
Mode:Managed Frequency:2.472 GHz Access Point: 3C:84:6A:51:45:9F
Bit Rate=150 Mb/s Tx-Power=31 dBm

Power Management:off
Link Quality=70/70 Signal level=-23 dBm

eth0 no wireless extensions.
Worked my way tenaciously thru google and this site trying everything mentioned, anywhere.
power saving off.
IPv6 disabled
noarp
All to no avail!

Tried a different sd card with a Etcher image of 3.8.1.
Default settings. Still the same issue. Drops repeatedly.
Then tried FR24 image instead to see if I had a dodgy wifi chip.
Using FR24 image on new SD card I have rock solid wifi connection for hours at time.
So, to get to the point!!
I think there is something about the 3.8.1 image build that doesn’t play nicely with ?my Netgear mesh wifi? I see one similar comment on the forums - but no solution
I am a complete novice in Linux and networking so there has been a huge amount of learning, and trial and error. Beginning to wonder if I’m going mad!
I can use wired connection for now (no problems, rock solid) but would dearly love to get wireless working, as the best location for my antenna is in the middle of a field and I wanted to set up a solar powered remote site, which obviously I can’t cable to, so need reliable wifi !
In desperation I now post here, to see if anyone has any guidance to offer as to where I go from here?
I see that dhcpcd is under active development and wonder if a newer version of that may help, but I’ve absolutely no idea how to do that or if its even possible without wrecking the install.
Any help gratefully received
Pretty please
ps tried DHCP and static IP address. No difference. Still “wlan0 carrier lost”
