The Internet disappears approximately every 20 minutes.

Good day everyone! Please help me figure out the problem. The bottom line is this: approximately every 20-30 minutes, the Internet disappears for a couple of seconds, sometimes for a couple of minutes. The cable is working fine, there are no interruptions with e-mail, there are no viruses on the computer through AVZ, ADWCleaner, DrWebCureIT. The Internet was connected normally, the provider also said that the connection from their side was normal. The driver for the network card has not been updated for the next month (I updated the last time a long time ago, but after the update everything worked stably). Internet from MTS. Windows 10x64 system lick. The cable is directly connected without any Wi Fi or anything else
