Hello, I got an new Laptop (Lenovo T14 Gen2 AMD) and it has RTL8852AE chip, it can connect to WiFi, but its very slow and unstable: --- 8.8.8.8 ping statistics --- 100 packets transmitted, 60 received, 60% packet loss, time 99514ms rtt min/avg/max/mdev = 578.297/4515.244/10612.149/2763.037 ms, pipe 11 I'm running on Debian bullseye with backport Kernel Linux 5.16.0-0.bpo.3-amd64 I reported this on github (https://github.com/lwfinger/rtw89/issues/133) and I added the following (as recommended): cat /etc/modprobe.d/50-rtw89.conf options rtw89_pci disable_aspm_l1=y disable_aspm_l1ss=y but it still unstable. Here are some sysinfo, and also some (dmesg) logs: BIOS Information Vendor: LENOVO Version: R1MET43W (1.13 ) Release Date: 11/05/2021 Address: 0xE0000 Runtime Size: 128 kB ROM Size: 32 MB
