(This is an experiment. Don’t know if you guys appreciate getting this kind of ask here at lobste.rs and a kind moderator (Irene) suggested I go ahead and ask as a try out)
These are two tech support questions whose answers I have not been able to get from my web searches. They are probably not related, except they both seem to be software related on the same machine and they are both slowly driving me mad. I thought to ask it here because you guys are my go to place for techie people.
Machine: MacBook Pro (Retina, 13-inch, Early 2015) OS X El Capitan 10.11.6 (15G1108)
Issue 1: Periodic network drop outs
Symptom: pinging a website, or even the router, will result in a string of small trip times (say 20ms) punctuated by much longer trip times (say 500ms - 1000ms) or even packet loss.
Internet search hit: https://discussions.apple.com/thread/1208774?start=0&tstart=0 (look for the answer by eyepac: https://discussions.apple.com/message/5748265#message5748265)
Solution: delete /Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist
Problem: The problem comes back after a while and the only solution is to delete the file again and reboot the machine
Issue 2: USB HDD drives no longer recognized
Symptom: USB mice, USB flash drives all work, but different USB HDD which work on other macs and windows machines no longer show up in DiskUtility or the System Report.
Solution: Reboot the machine.
Problem: It works for a while, but then stops working.
Thank you so much for considering this problem!
