Hi, I have a 2014 Macbook Pro and I've been experiencing on and off a very annoying slow loading of web pages. They take tens of seconds to load, and in most cases the browser just gives up and displays the error message "There is no internet connection", "The site can't be reached" or "is taking too much time to respond". Here are some facts: 1. It happens with ALL my browsers (Chrome, Safari, Firefox), on ALL the networks I tried (home, work, cafes, you name it...), and as far as I can tell on ALL webpages. 2. The problem usually lasts for a few days, then it works correctly for a while, then it stops again for a few days, and so on. 3. It happens both with WiFi and with Ethernet connection. 4. The data transfer speed of the Wifi and Ethernet seems fine: - speedtest.py run from the terminal gives Download 49.67 Mbit/s, Upload 5.43 Mbit/s. - I also measured the speed directly by downloading a 80Mb file, it took less than a minute with Wifi. 5. I have no problem using ssh and scp from the terminal and they work as expected. On the other hand if I try to load a webpage from the terminal using wget I get the same slow loading. So I suspect the problem is with http. 6. I have an iMac on my home network and I never experienced this problem on the iMac. When connected to the home network, the iMac and the Macbook use the same DNS servers. 7. I tried using the Google Public DNS servers it does not changing anything. 8. Closing and reopening the browser or the connection doesn't do anything. Restarting the computer sometimes, but not always, resolves the problem temporarily. Any help greatly appreciated.
