Hi all. I connected my Dell Vostro 5581 laptop to the new router via 802.11ac (wifi 5) and it worked stably for some time. But at some point, every few minutes, the connection is constantly lost. At the same time, a phone is connected to the same router via 802.11ac and it has no problems with communication. Most likely the reason is in the laptop. Any ideas?

Do you have other device for A/B Testing? I suspect your network card may be due for an upgrade as the Dell Vostro 5581 network card is infamous for faulty and top the return item in Amazon.
Iβd suggest, after confirming with A/B Testing, better to upgrade to wifi6e and above e.g. here. Just make sure the correct socket i.e.
