I am seeing some progress when building 5.3.0-rc1+ with the wireless-drivers-next patch for the rtw88 kernel module. Before the patch, my realtek r8822be was not recognized at all. After the patch, Realtek ethernet as well as wireless card r8822be are recognized and I can see a list of wireless access points. But for some reason, ping to my local gateway servers (both Ethernet and wireless) fail. Running tcpdump on my wireless and ethernet interfaces shows that ARP requests are showing up, but dns resolution doesn't work. I can associate with a wireless access point with wpa_supplicant and my ethernet port is getting a DHCP lease from my dhcp server, however. And for YH~ Here is a dropbox link to debug info containing the output of dmesg, lsmod, and journalctl -b0 zipped up into a tarball: https://www.dropbox.com/s/pl85ob09y6q2qky/debug_5.3.0-rc1%2B_with_rtw88_pat= ch.tar.gz?dl=3D0 Thanks for your help!
