Kada su u pitanju ADSL ruteri preporučujemo Efficient Networks - Siemens SpeedStream 5861 ADSL Firewall VPN ruter 4 x UTP LAN. Radi se o odličnom uređaju sa velikim mogućnostima i brojem opcija koji omogućuje jednostavno spajanje više računara na Internet preko ADSL linije. Što se SpeedStream 5861 rutera tiče možete na Internet spojiti i par stotina računara, maksimalan broj je ograničen praktično samo zagušenjem ADSL linije. Zahvaljujući ugrađenom Firewall-u SpeedStream 5861 čini izlazak na Internet neuporedivo sigurnijim nego ukoliko koristite običan modem. U slučaju prekida ADSL-a ima mogućnost uspostavljanja back-up veze preko analogne telefonske linije. Uređaj je nov i nekorišcen ali bez kutije. Dajemo standardno godina dana garancije.  SpeedStream 5681 već funkcioniše i kod nas na par stotina linija. Dobijate bez sumnje vrhunski brand uredaj po ceni povoljnijoj od no-name opreme !!!
