Routerimiz himoyasini sozlang. Buni amalga oshirish uchun, Security bo’limi va " Security Mode" punktiga o'ting, WPA2 Personal-ni tanlang. WPA2 Enterpriseni tanlashning hojati yo'q, chunki uning ishi uchun biz qilmagan server radiusiga muhtojmiz. Shifrlash algoritmi AESdan ajralib qoladi va kod so'zini kiritadi. Men Habrni namoyish qildingan.

8. 
   3 qurilmani (smartfon, noutbuk va kompyuter) qo'shing. Keyin rj-45 uchun ulagichlarni Wi-Fi antennasiga almashtiring (smartfonda, standart antennaga).
   
9. 
   Config ko'rinishida rouerga o'rnatilgan sozlamalarni o'rnating. Ushbu operatsiya barcha qurilmalarda bajarilishi kerak.
   

10. 
    Har qanday kompyuterning ish stoliga o'ting va buyruq xohishini oching.
    

11. 
    Router tomonidan chiqarilgan qurilmalar manzillarini tekshiring. Buning uchun ipconfig buyrug'ini kiriting.
    

Displeyda ko'rinib turganidek, router 192.168.0.100 dan 192.168.0.150 gacha manzillarni taqdim etadi.

12. 
    Ping buyrug'i yordamida har qanday qurilmadan tarmoq ishlashini tekshirib ko'ramiz. Biz router manzilini (192.168.0.1) va oq adresni (120.120.0.1)
    

manzilga 2 ta manzilga yuboramiz, ya'ni qurilmaning Internetga kirishini tekshiramiz.

Demak, hammasi ishlayapti.

Natijada 2-variantdagi rasmda ifodalangandek Wi-Fi tarmog'iga ega bo'ldik.

Topshiriq №1 (variant №3)

1. 
   Oldingi laboratoriya ishlaridan tugagan loyihani oching.
   

2. 
   Dasturning ish joyida kirish nuqtasini yarating va uni kalitga ulang. Agar so'ralsa, kirish nuqtasi sozlanishi (Port 0 - jismoniy port va Port 1 simsiz)
   

3. 
   Simsiz kirish nuqtasi uchun boshqa VLANni yarating.
   
4. 
   Router 0 VLAN-4 sozlamalariga qo'shing va Internetga kirish uchun ruxsat ro'yxatiga qo'shing.
   
5. 
   Biz buni oldingi amaliyotda (VLAN va PAT) qilganimiz uchun bunga batafsil to’xtalmaymiz, ammo qurilmadagi barcha buyruqlarni ro'yxatdan o’tkazamiz.

Ko’rinib turganidek, hammasi ishlayapti.
