Networking and Home Storage

Networking is the part of a setup people only think about when it breaks, and then they buy the wrong fix. Nine times out of ten the problem isn't your internet plan, it's the box your provider gave you or where you put it.

Routers and Wi-Fi Standards

Start by getting off the ISP's rental unit. Those are built to a price, the software is usually dated, and you're paying a monthly fee forever for the privilege. A decent retail router pays for itself in a year or two and generally has better range, better settings and longer support.

On standards, Wi-Fi 6 is the sensible baseline and it's cheap now. Wi-Fi 6E added the 6 GHz band, which is fast and clean but doesn't travel as far or punch through walls as well, so it's best in the same room or an open space. Wi-Fi 7 adds more of the same plus the ability to use multiple bands at once, which helps in dense apartment buildings with a lot of competing networks. Real talk though, if your plan is 500 Mbps and you're streaming and browsing, Wi-Fi 6 is already more than your connection can feed. Upgrade for coverage and device count, not for the number on the box.

Mesh vs Extenders vs Access Points

If you have dead zones, mesh is usually the answer and a plug in extender usually isn't. Extenders rebroadcast the signal they receive, which cuts your speed roughly in half and often creates a second network name your phone refuses to switch off. Mesh systems use dedicated backhaul and hand your devices between nodes without you noticing, which is the actual thing you wanted.

The best version of mesh is wired backhaul, meaning each node connects back to the main router over ethernet instead of Wi-Fi. If you have ethernet in the walls, or you can run one cable, do that and the system will roughly double in performance. Also, node placement beats node count. One unit halfway to the dead zone works better than three units clustered at one end of the house, and a router shoved in a closet behind a TV is fighting for its life.

Wired Networking

Cable categories are wildly oversold. Cat 6 handles a gigabit over any run length in a house and 10 gigabit over shorter runs, which covers basically everything you'll ever plug in at home. Cat 8 is for data centers and the premium is marketing for a residential buyer. Buy plain Cat 6, spend the savings on length so you can route it neatly.

If you can't run cable, MoCA is the underrated option, since it sends network over the coax already in your walls and it's far more stable than powerline adapters. Powerline works over your electrical wiring and its performance swings wildly depending on the age of your house and what circuits things are on. It's worth trying if it's your only option, just buy from somewhere with a return policy.

NAS and Backups

The rule worth memorizing is 3-2-1. Three copies of anything you care about, on two different types of media, with one of them off site. Sounds like overkill until a drive dies or ransomware encrypts your photos, and then it's the only thing that matters. A NAS covers the local part nicely, gives you a shared drive for the whole house, and doubles as a media server or a place to dump phone backups automatically.

The thing people get wrong is thinking a NAS is a backup. It isn't. RAID protects you when a drive fails, and it does nothing when you delete the wrong folder, your house floods, or something encrypts everything on the network. So pair it with a cloud backup or a rotating external drive you keep somewhere else. Two bays is enough for most homes, four gives room to grow, and drives are the real cost so plan for buying them in pairs.
