Kao što je već tradicija na ovom blogu, stiže još jedna lozinka Telekomovog rutera, ovaj put je to misteriozni Nokia G-240W-C ONT! Uživajte u administracionom pristupu na vašoj opremi :)
Jedno malo „novogodišnje iznenađenje” za korisnike MTS-ovog xDSL Interneta sa Iskratel Innbox V46 modemom - šifra za superadmin i admin nalog na modemu!
Nailazim na sve više korisnika Interneta na raznim forumima koji se žale da im ne radi port forwarding, tj. “otvaranje portova”, na modemu, i da ne mogu da koriste video nadzor, hostuju servise lokalno, koriste BitTorrent, itd. Odlučio sam da napišem ovaj članak kako bi korisnici mogli lakše da se informišu o ovom problemu i o načinima rešavanja.
Mesh WiFi sistemi predstavljaju relativno novu inovaciju na tržištu kućnih WiFi rutera, koja omogućava lakše pokrivanje većih objekata sa stabilnom i brzom WiFi mrežom, uz jednostavno podešavanje i održavanje. U ovom članku ću objasniti šta su to Mesh WiFi sistemi, i uporediću ih sa WiFi ripiterima - tradicionalnim rešenjem za povećanje pokrivenosti.
Propaganda o “5G revoluciji” od strane medija je dostigla svoj vrhunac, ukazujući na “četvrtu industrijsku revoluciju” uz pametne gradove, veštačku inteligenciju, samoupravljajuće automobile, hiperpovezane sisteme, itd. Jasno je da je u pitanju klasično napumpavanje nadolazeće nove tehnologije, i da bi navedeno moglo biti štetno po komercijalizaciju i razvoj 5G mreže. U ovom članku želim više da se fokusiram na realna unapređenja koja će 5G tehnologija doneti u naš život.
In this post I show you how to install the excellent OpenMPTCProuter software, and achieve true dual-WAN Bonding, the “holy grail” of people who want high speed Internet but don’t have access to it. Oh, and it's CHEAP!
Korisnici većih Internet paketa često imaju problema sa podrškom svojih provajdera, jer podrška jednostavno ne želi da prihvati reklamacije na brzinu na WiFi i tvrdi da provajder nije odgovoran niti može da utiče na brzinu Interneta preko WiFi. U ovom članku ću pokušati da korisnicima približim način rada WiFi tehnologije i legitimne razloga zašto brzina Interneta na WiFi nije ono što očekuju.
U ovom tekstu ću vam pokazati kako da aktivirate Telnet pristup na Ubee EVW32c DOCSIS 3.0 Voice Gateway uređaju. Telnet pristup možete koristiti za napredna podešavanja, nadzor parametara uređaja, instalaciju softvera, i još mnogo drugih stvari.

Južna Koreja je u decembru 2018. postala prva zemlja koja je uvela 5G mrežu, i moramo priznati da je mobilna industrija dostigla neverovatan napredak od kada je je prvi poziv putem mobilnog telefona obavljen „davne“ 1973. godine. Da bismo zaista razumeli kako smo stigli dovde, moramo ispratiti nezaustavljiv rast i razvoj bežičnih standarda od prve generacije (1G) do mesta gde se danas nalazimo, na početku globalnog širenja 5G mreža.
