Mobile Internet disappears every 8 minutes for 20-30 seconds?

Question

Computer networks

I distribute the Internet to the computer from the phone, when I sit in it I noticed a pattern that every 8 minutes the Internet disappears tightly for 20-30 seconds. And the connection with the Internet does not disappear, but the speed drops to zero. Connected both by distribution and by yusb. Everything is fine with the computer, since there are no problems through any other Wi-Fi. Phone Huawei p40 lite.
