I have a problem with wifi internet. OS LinuxMint 19.1 Cinnamon 64, Lenovo G30-50
From time to time my internet connection stops and I have to break and restore w-fi connection to cure it. I noticed that I have a 100% probability to get this effect when I try to download a big backup file from my web-hosting (ISP manager panel). The file is about 2 GB, and download process can stop between 100-900 MB, and when it happens I can not open any other sites (or they are loading very very slow). But! The Google search and Youtube still works perfect and fast! So, this is not a deep protocol problem like MTU (I set it to 1492 like in router settings) or IPv6 (I disabled it). I tried to use Google DNS instead given by provider - the same result. I have access to Google and don't have access to other sites until I turn OFF and turn ON the wi-fi in tray. These problems started when I changed the provider and router. So, I really don't sure is this a problem with linux-mint or this is a problem with provider/router. But if this is a problem with the router why I can cure it by OFF-ON switching my wi-fi connection in network manager in my laptop? May be someone can advise me something, or at least this topic can be useful for people who will discover the same issue of their wi-fi.
This is network manager in normal regime when all sites works:
And this is how looks network manager when all sites don't work (but Google and Youtube still works! with "0%" of wi-fi power!)
But at the same time when I see 0% wi-fi power in opened NM window the power is non-zero when mouse only hovers the Network Manager tray icon:
When I try to donwload other big file (for example, linuxmint iso from this site) all things are OK. But in the any case this is quite strange that (potential) problems on dowloading from one server can cause a problems with internet which affects all other sites.
