🌐 Home internet ‘from day one’: temporary 4G/5G router and permanent contract

🚀 Temporary internet upon arrival

📡 Mobile router/modem: plug & play

• What to get: a pocket 4G/5G router or a stationary ‘home LTE/5G’ (better for long calls).
• SIM/eSIM: separate data profile for the internet (so you don't have to rely on your personal SIM).
• Limits and FUP: check the ‘hidden’ shaping policy after N GB and whether tethering is allowed.
• Where to place it: closer to a window, at a height, away from concrete/metal and microwaves. For 5G, look for a ‘view’ of the base station (at least approximately).

📱 ‘Phone as a modem’ — backup plan

• Suitable for 1–2 days of protests or as a backup.
• Plug your phone into a power source and cool it down (stand it by a window, switch to 4G mode if it overheats).

🔗 Permanent contract (overview)

🔍 What to look for when choosing

• Speed and symmetry: for 1080p calls and cloud backups, 100/100 Mbps and above is more comfortable; if there is asymmetry, check the upload speed (key to video/screen sharing).
• Ping/stability: benchmarks — ping < 30–40 ms, jitter < 15 ms.
• Equipment: your own router (WPA2/3, 5 GHz) or rented from the operator; check the bridge mode if you need your own firewall/mesh.
• Term and penalties: contract term, termination fee, equipment rental/purchase, address transfer.
• Access type: fibre/coax/DSL/5G home internet — check coverage and connection times at your address.

📶 When to leave 5G as a ‘permanent’ option

• Good signal in the apartment, stable upload, no fibre optic lines in the building.
• Paired with Ethernet to your desktop and an external antenna/proper installation location.

📶 Wi-Fi in a rented property: ‘sharing with neighbours’ — risks and how to protect yourself

🔒 If Wi-Fi is ‘shared’ by the landlord

• Ask for a guest network (Guest SSID) with a separate password and no access to local devices.
• Change the router's admin password and use WPA2/WPA3.
• For work, use a VPN on your laptop; do not store sensitive tokens on shared devices.
• Disable IoT on the working SSID (smart lamps/cameras — on a separate network).

📊 Performance and stability test

🕒 How to check in 20–30 minutes

1. Speed test at 3 points in time: morning/afternoon/evening. Look at upload, ping, jitter, and packet loss.
2. Wi-Fi coverage throughout the apartment: 2.4 GHz — for ‘distant’ rooms, 5 GHz — for the workplace.
3. 10-minute test call: video + screen sharing; check the backup channel (mobile/router).
4. Interference: switch the router to a less congested channel, place it higher and closer to the ‘lines of sight’.

✅ Checklist before the working week

• Router in place, passwords changed, guest network enabled.
• Stable upload ≥ 10 Mbit/s, ping < 40 ms, jitter < 15 ms.
• Ethernet to your desktop (if possible) or stable 5 GHz.
• Backup: mobile hotspot / second 4G/5G profile.
• VPN working, corporate services open without lag.
• Router reboot timer once a week (optional).
