Mid 2011 iMac 21.5, MacOS High Sierra, WiFi/Ethernet failure?
Good morning everyone!
I purchased the in title mentioned iMac off of my cousin. I am not exactly sure why he was going to throw it out and I can't find out exactly since he is unreachable while being overseas. His family told me it was something to do with the keyboard and mouse. I have since purchased a cheap keyboard and mouse from the good ol' Walmart, erased the disk and reinstalled MacOS High Sierra following instructions found here.
Almost immediately while using the Mac, the wifi would lose connection to my router. It would then stop showing all possible wireless connections in the area. When this occurred, I attempted to use an ethernet cord which too would not work and the Mac wouldn't even recognize a cord was plugged in.
The only temporary solution I have found is to restart the Mac. After restart the wifi and ethernet port work for a short time and then fail out again.
I have since erased the Mac and reinstalled the OS as a clean slate, erased all other wifi connections and re-established with my router, compared network preferences with my MacBook which is connected to the same router, and other possible solutions found on the web.
A lot of the solutions I have found are on the part of the router it self, but with the Mac not finding any other networks, including my iPhone's hotspot, and the ethernet port won't work either I feel as though it is an internal issue on the end of the Mac.
I have not found another issue quite like this one in the community and have searched the internet for the past day now to no success. Absolutely any help and advice would be greatly appreciated.
