The RPi seems to have lots of difficulties keeping the network connection open. Putty reports network closed error quite often and it’s a bit sluggish typing things on the terminal.
Could it be that the Wifi module is actually dying? Today I had one network disconnect in the RPi and it didn’t reconnect until I powered it off and on. I’m unable to do a sudo apt update to start updating packages, it seems to just timeout even if I’ve tried different servers in the config file.
All the other wireless device seem to work fine. It’s been connected to my 2.4GHz all the time I’ve used it. I actually thought it supported only that and not 5GHz. The router doesn’t show any errors in it’s logs.
