I was facing WiFi problems

The only thing which helped me is disabling acpi in grub. But when my wifi started working good, the performance of the laptop decreased tremendously. Any ideas what to do, please?

Before i turned off acpi:

$ journalctl -b | grep ASPM
січ 10 22:35:15 kulak-HP-Laptop-15s-fq2xxx kernel: ACPI FADT declares the system doesn't support PCIe ASPM, so disable it
січ 10 22:35:15 kulak-HP-Laptop-15s-fq2xxx kernel: acpi PNP0A08:00: _OSC: OS supports [ExtendedConfig ASPM ClockPM Segments MSI EDR HPX-Type3]
січ 10 22:35:15 kulak-HP-Laptop-15s-fq2xxx kernel: acpi PNP0A08:00: FADT indicates ASPM is unsupported, using BIOS configuration

upd: When i am not disabling acpi i am facing errors on boot: https://ibb.co/WGDnZ68

Need a lot more info here... specifically outputs on `lspci`... could be anything from firmware to unsupported wifi card. It's likely those ACPI errors are meaningless, just extensions the vendor made for a proprietary driver that the kernel doesn't know how to use.
I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
