The router frequent drops the WiFi signal. The manufacture's tech support has made several suggestions to address the problem - everything from switching the frequency bands, re-setting the router, to replacing it. I have done everything asked, including router replacement and it still drops the WiFi signal. At this point, I may have to dust off my old R6300 NetGear router (which never had these problems).

I have taken the computer to an Apple store because the battery I purchase shows service red light, they tell me that this must be a refurbished battery as they do not put scan bars on any of their batteries. The battery show 157 cycles but it already shows service on the computer. I had to put my old Original battery back in the computer. Very disappointed as it was supposed to be NEW and Apple Batter. They told me that battery should last at least 1,000 cycles.
