[I hope this belongs here - if not, lmk and I'll delete the post. I've been mainly lurking here so far]

In a month I'll be in charge of "IT-stuff" in a small office. People are generally happy if there is internet and VoIP is working. I'd like to take the opportunity to learn what I can, while I have the chance. And maybe/hopefully contribute to make it a bit better. For now I want to look into how I should configure wifi and access for office/guests (and devices that are used obv.) Thing is, I don't know where to start and what I actually can do. Do I just google "how to configure wifi in the office?" and go from there? (I'm a bit hesitant to do that since I'll not be able to tell if what I find is good) Is there any good reference material you would suggest? Any suggestions are appreciated.

I studied business informatics (but it's been a while) so I'm not completely clueless (but still clueless hehe).

Eh, I think 1&7 aren't all that important. Sure, understanding the difference between a dumb switch and a smart switch is absolutely important, but the actual OSI layers isn't that important. Likewise with packat structure.

The important thing imo is to understand that networks are layered and what the tradeoffs and benefits are for generally going higher, but the specifics are super easy to reference later when needed (rare).

In general, don't get caught up in memorizing stuff, focus instead on practical ways to practice concepts. Set up a VLAN, configure QOS on a smart switch and then on a router, configure a guest LAN with no access to anything on the LAN, etc. Most people learn better by doing, so spend your time doing as much of that as you can.
