I need to get a new company router but am looking for a secure but low cost solution. My first idea was to get a 20€ TP-link router and flash it with DD-wrt, but the latest firmware is a year old and I can't seem to find an option to do an auto update.
Can dd-wrt update itself without any user input?
If not, are there any secure alternatives that I can use instead?
I want to set it up once and then leave it doing it's job on auto updates.
There is no official method of auto-updating the DD-WRT firmware. It would contradict with all the safety precautions suggested by the DD-WRT team because, if not followed correctly, might end up in a bricked router.
Here are a few links that might help you out:
Never restore old backups from previous versions! Skipping these steps could lead to a bricked device!
My suggestion would be to check for a new version once a month and then take the time to do it manually, just to make sure that no unexpected things will happen.
Edit: Just for reference, I bought a used TP-Link TL-WR1043ND for 20€ with a relatively up-to-date DD-WRT firmware. You can take a look here for newer firmwares: http://dd-wrt.com/site/support/other-downloads?path=others/eko/BrainSlayer-V24-preSP2/2014/
This software will automatically download new firmware images and update DD-WRT installations. It should be ran on a linux box with network access to the device(s).

To avoid update issues, make sure you are running a relatively recent DD-WRT image before using it.
