Recently I updated my router's firmware to DD-WRT. None of my devices have problems with this update. None of the other MacBooks, none of the Windows laptops, none of the phones have issues.
Only my 2016 15" MacBook suddenly has connection issues, since the DD-WRT update. This laptop has no issues on any other WiFi networks. I tested this with at least 6 other networks.
What happens during connection issues:
- Wifi stays connected
- Can't ping to any IP outside of the first router's network.
- I live in the middle of no-where, with maybe one other wifi network around.
Where do I start searching for this issue? I searched the log files on the router, and the log files on the laptop, but I did not find anything suspicious.
This is the wifi.log.
