The strange thing is that it connects to the network, i have internet for some time (usually between 1 and 10 minutes) and then it disconnects. After that, the applet shows me something like device not ready and i can only restart the computer to connect. Then it crashes again... I also tried a fresh install with the same results. I used 19.04 and 19.10 on the same laptop as my primary operating system and wifi worked flawlessly. Since I do my work on this laptop i was forced to downgrade back to 19.10 for now. This is my lshw -C network (from 19.10 If I remember correctly it was RTL8822BE also in 20.04) *-network description: Wireless interface product: RTL8822BE 802.11a/b/g/n/ac WiFi adapter vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:07:00.0 logical name: wlp7s0 version: 00 serial: dc:a2:66:80:7d:7d width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=rtw_pci driverversion=5.3.0-46-generic firmware=N/A ip=192.168.0.146 latency=0 link=yes multicast=yes wireless=IEEE 802.11 resources: irq:141 ioport:4000(size=256) memory:a4300000-a430ffff *-network description: Ethernet interface product: RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:08:00.0 logical name: enp8s0 version: 15 serial: 8c:16:45:e9:e9:a8 capacity: 1Gbit/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix bus_master cap_list ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8169 firmware=rtl8168h-2_0.0.2 02/26/15 latency=0 link=no multicast=yes port=MII resources: irq:17 ioport:3000(size=256) memory:a4204000-a4204fff memory:a4200000-a4203fff and my lspci -nnk | grep -A2 0280 07:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd.
