How to solve wifi problem on macbook?

Question

WiFi

Has anyone encountered the fact that the Macbook Air and iPhone synchronously stupefied? I mean that the update, etc. are downloaded at a very low speed, you can practically say they are not downloaded, but everything else, torrent, etc. downloaded as it should at 5Mb/s. Can you tell me what's the matter?

Answer 1

There may be problems with the DNS at the provider. You know, torrents do without DNS...
