One MacBook Pro slower internet than two others (and an iPhone)
I noticed yesterday that the reason my kids were complaining about the games they were playing being "slow" was a legitimate slowness of internet on the MacBook Pro they were using. I am seeking advice on what I can do to determine the cause and fix the problem.
How do I know there is a problem?
I ran a few tests, putting the devices in the same place (about 1' away from an Airport Express that's plugged into Ethernet).
(Ping / Download / Upload / Model or Device / OS)
- 17ms / 2.58 Mbps / 0.75 Mbps / MacBook Pro (Late 2016 13-inch) / 10.14.6
- 14 ms / 92.21 Mbps / 27.86 Mbps / MacBook Pro (Mid 2012, 13-inch) / 10.12.1
- 11ms / 88.64 Mbps / 41.80 Mbps / MacBook Pro (2017 15-inch) / 10.14.6
- 19ms / 45.9 Mbps / 32.1 Mbps / iPhone 8 / iOS 12.4.1
Comment: when a 7 year old MacBook Pro beats a three year old one, 35 times faster, there might be a problem, right?
I have already tried the following:
- Updated to the latest updates for 10.14.16 (not upgrading to Catalina yet)
- Tested from a newly created user account on the slow MacBook Pro
- Reinstalled MacOS (Mojave) over the existing installation
- Checking the internet speed when plugged in via network adapter / 10BaseT to Ethernet (faster, but only half as fast as the other laptop in the same place)
- Reset the PRAM
At times, I've seen it as high as 7 or 8 Mbps (Download) but it is very often just piddling along in a range of 1 to 2 Mbps.
What do you all think I should look at next?
