Labthrift Labthrift What to buy. What to skip. Why.

Written 4 Sep 2026. This is a how-to, not a product card.

When the house share won't open

Finder, File Explorer, or the phone can't open the house folder. Check the computer is on, confirm the address, then match the error (path not found, login failed, can't write, disk full). You don't need a NAS.

Haven't made the folder yet? Start with a file share. Need the address? Find it on the house network. First open walk: open from a laptop or open from a phone. This note is only for when open fails, or used to work and now doesn't.

Skip until you have a real symptom

Copy the exact error from Finder, File Explorer, or the phone. "Network path not found," "login failed," "access denied," and "disk full" are different fixes. Don't buy a NAS for a wrong address or a stale password.

What this is

The house share needs five things that still match: the computer awake, you on the same house network, the right address plus share name, the Samba password, and room on the disk. One of those usually drifted. Soft-off, guest Wi-Fi, a new DHCP lease, a remembered bad login, or a full drive. The walk below is order of cheap checks.

Step 1: is the computer awake?

Power light. Fan. Screen if it has one. If it looks asleep or dead, start with is the computer still on?. Soft-off on purpose? Wake it from the house network: wake the computer from the house network. A laptop that slept with the lid closed needs don't let the laptop sleep before you chase share bugs.

Step 2: same house Wi-Fi

Your laptop or phone must be on the main house Wi-Fi (or a cable into the same router). Not guest Wi-Fi. Not a work VPN. Not cellular. Guest Wi-Fi often cannot see the computer on purpose — same idea as when guest Wi-Fi still shows ads. Turn the VPN off for this test. Stay on the house network only.

Step 3: confirm the address and share name

Don't reuse last week's number from memory. Look it up again: find it on the house network. Write down the address and the share name you set. Examples:

\\192.168.1.50\photos

smb://192.168.1.50/photos

Use the real number and share name, not those examples. Wrong share name looks a lot like "path not found."

Step 4: match the symptom to a fix

What you seeWhat to do
Can't find path / connection failed / network path not foundThe computer may be up, but Samba stopped or the firewall hid it. Check on the computer: systemctl is-active smbd. If ufw is on: sudo ufw allow Samba. Full walk: when the house share disappeared, check the computer.
Login / password failed / access denied at the promptWrong share password, or a remembered bad one. Set or reset it: set or change the house-share password. Then clear the device's saved copy: forget the saved house-share login (Credential Manager, Keychain, or the phone bookmark). This is not the SSH login unless you chose the same password on purpose.
Folder opens but you can't copy a file inFull walk: when you can open the house share but can't write. Short version: Linux owner is usually wrong. sudo chown youruser:youruser /srv/share (swap user and path), then try again.
Photos stop / disk full / no space leftThe share is fine; the disk is not. Walk it: when the computer's disk is full. Quieter look: see if the computer still has room. If the system disk is small, park the folder on a USB that stays plugged in: put the house folder on a USB disk.

Check

Open the share again from a laptop or a phone on house Wi-Fi. Copy one small file in. Copy one out. If that works, you're done. If it fails after a reboot, re-find the address — DHCP may have moved the number.

What this is not

This is not a reason to buy a NAS tonight. It is not SMB opened to the internet. It is not Synology Drive, a coffee-shop VPN, or a third-party "network drive" app stuffed with ads. House network only until you actually need remote access.

What next

First open walks: from a laptop, from a phone, from a Chromebook, or from a Linux laptop. Need a second person with their own login? Add another person to the house share. Someone should leave later: remove someone from the house share. Share password stuck? Set or change the house-share password. Device still using the old one? Forget the saved house-share login. Samba stopped? When the house share disappeared, check the computer. Disk full or getting tight: when the computer's disk is full. Quieter look: see if the computer still has room. Dump camera-roll photos: save phone photos to the house share. Opens and writes but crawls: when the house share is slow. Check live connections with see who is using the house share. When you want a second copy, that is a backup of the house folder. Soft restart without a full reboot: restart Pi-hole or the house share.
