I am encountering a weird issue regarding the Wi-Fi speeds on my (Apple Refurbished) Macbook 15" Mid-2015. On my home network, sometimes the wifi speeds would be extremely slow. I ran "ping google.com" in terminal and the ping times are >1000ms. The weird thing is that this rarely happens on my school network, only when it is connected to my home network is when this issue begins to arise.
Solutions attempted -
- Switching between 2.4 and 5 Ghz networks. Issue still persists.
- Deleting a .plist file which stores wifi configuration information. Issue still persists.
- Removing the Wi-Fi service in system preferences and added it back in. Issue still persists.
I have also tested if the problem exists on a ethernet connection, and it does not happen on it. Other Wi-Fi connected devices on the network never had this problem, even my old macbook didn't seem to have it aswell.
Macbook Specs -
Intel Core i7 2.8Ghz
16GB 1600Mhz DDR3
1TB Flash Storage
Intel Iris and AMD graphics.
OSX Sierra 10.12.5
I might go to the apple store and see if it can be fixed there since it is still under warrenty.
