The first step is to decide on a tariff plan. Letai offers 3 to 7 options depending on the region, but not everyone needs speed 1 GbpsHere's how to choose the best package:

• 📱 For smartphones and social networks: enough 50–100 MbpsThis is enough for watching videos simultaneously in Full HD on 2-3 devices and comfortable work in messengers.
• 💻 For remote work: minimum threshold - 150 Mbps, if you use Zoom/Teams + cloud services. If you have frequent video conferences, it's better to take 300 Mbps.
• 🎮 For gamers: the priority is not speed, but ping (Delay). Choose plans marked "Gaming" or check reviews for stability in your area.
• 📺 For 4K streaming: one device requires 25–50 Mbps, but if you watch on several screens, take it 200+ Mbps.

Please note traffic limits: in basic tariffs Letai Sometimes the "unlimited" plan is only available at night (from midnight to 8:00 a.m.), and during the day, speeds can drop after downloading 1 TB of data. Check with your manager! Also, ask about promotions for new clients — often the first 3 months offer a 30–50% discount on the tariff.

Login: letai
Password: the last 8 digits of the router's MAC address (found on the sticker)

Step 2. Setting up an Internet connection.

Go to the section Network → WAN (or Internet → Connection). Select connection type:

• 🔄 Dynamic IP (DHCP): automatic tuning (most commonly used) Letai).
• 🔐 PPPoE: If your provider has provided you with a login/password (enter them in the appropriate fields).
