MACBOOK PRO 2015 WIFI DISCONNECT FROM SLEEP YOSEMITE AND EL CAPITAN HELP :/
Hello, I recently bought a brand new macbook pro 2015 13.3 inch edition last month and when I close the display lid or put my laptop into sleep, and wake up the display my network settings says that my wifi is connected but safari web pages and other internet features don't work and I have to turn wifi off and on again for it to work again. I've tried absolutely everything already to try to fix the issue such as reseting; pram, smc, removing plist files, removing and reseting pefferred networks, adding new location and reseting service order, clean install of El Capitan 10.11 and updated to 10.11.2 and even got my airport card replaced and macbook pro replaced shorty after. Before I replaced it, it ran El Capitan. And now the replaced macbook pro is running Yosemite 10.10.5 and the issue is still here.
I found a temporarily solution which was to download nosleep program extension Yosemite version which permanently disables sleep function but eventually it may damage my display. I want to know if anyone found a proper solution to this problem? My wifi works well on all my other devices such as my: 2 pc's, chrome book, iPad and iPhone. It just gives problems on my macbook pro only. Is anyone else experiencing this issue? And have you found a proper solution that I didn't mention? also I have Time Warner Cable and I have a 2 in 1 modem router by Arris model DG1670A which has 2.4 and 5G bands and the issue happens on both frequencies. I also have the 300/20 DL/UL plan which allows to connect multiply devices to the internet if that helps. I tried my macbook pro on a neighbors wifi connection and on the apple store wifi connection it didn't disconnect and worked properly but I didn't get to try it for that long to determine if it was working well.
Im thinking of buying another internet modem router but I don't want to spend the money if its not gonna fix the issue and if this problem can't be fixed would it be wise to return my macbook pro?
