No internet connection after battery died

My laptop ran out of battery yesterday and when I wanted to turn it back on again today, I wasn’t able to find any available connections. LAN isn’t working either… Both inxi -Fx and ip link show show the state as down and trying to set it to up doesn’t change anything. (sorry for not copy-pasting the direct output, I can’t access anything on the laptop and would need to type everything on my phone…). My wireless network adapter is QCA9377 and my kernel version is 5.4. I’ve tried pinging my router using a usb ethernet adapter but ping simply says that the network is unreachable. If I boot from a usb stick, I can access both WiFi and LAN without a problem, so it seems to be a software issue.
Any help would be much appreciated!
