Turns out it was my ISP. Came out 3 times. Told them it was something on their end but they insisted nothing on their end and replaced all fittings etc. After they left still had the problem. Called to have lead supervisor check but a couple of days later mysteriously resolved.
I should mention that not only my PC but all other wireless devices in the house experience this. I'm only using my PC and ping to try to figure it out. So, it has to be either the router, modem or Spectrum service.
Still having intermittent connection problems so not the firmware. I've talked to my ISP (Spectrum) and they say everything's fine on their end. When I ping google I get occasional "timed out" (like every 10 minutes or so that last about 1 minute). Any suggestions?
ping -t google.com
I think the statement I made accurately and completely states the case "I upgraded firmware to v384.14 and some of my clients don't work with it (ASUS zenpad). I had to revert back to 384.12.". What more do you need?
