If you are experiencing inconsistent Internet Speeds, it sounds like you will want to look into getting support for your router and or network connection. You could also check with Apple to do testing to see if perhaps you have a defective Wifi card? Does your iPhone get consistent high speeds, if so then sounds like you may have a defective wifi card or something. If iPhone is also intermittent would assume its your router setup/internet connection. As there isn't any wide spread internet connectivity issues with this model. My home gets 250mbps with Comcast. Depending on my location on the house, how many, and which devices are currently active and their load, I typically get about 220-240mbps. Plugging in via ethernet does give me consistently 250mbps, but that is the case with any computer. To note it did take a long time get my network setup to give the best speeds as there are so many factors that affect that beyond the computer.
