Thanks for replying.
Ok, I know OpenWrt is almost usable just tout of the box.
However, I think there are settings that can be improved because I have the feeling that signal strength is a bit weaker than the shitty ISP router before. As an example, today, while I was in my home office (by other words, bathroom), signal was like with 2 out of 5 bars on my smartphone. Usually I get all the bars with ISP router, so is it reasonable that something might just be improved?
I'm also looking to change the DNS servers but I'm not sure where that should be changed. Too many options for a newbie to pin point it right away.
If you can give me a hint on where to change that, I would appreciate. I'm trying to do things from SSH where I have already configured SSH keys to connect without the need of sending plain text passwords, so I'm trying to use SSH, for now!
Is the way to setup different DNS servers the one stated here:
on section DNS Forwarding??
I guess it's a bit down further in the page.
