Základní informace
Jsou tři typické příčiny problému síťové konektivity
- Počítač není správně nakonfigurován k tomu, aby mohl využít výhody síťových zdrojů.
- Síťový zdroj není na síti dostupný (nebo aktivní).
- Jedná se o problém s kabelem, který zabraňuje připojení.
Jak poznáte, v čem je problém?
Fluke Networks ukončilo tuhle tipovací hru svým NetTool Inline Network Tester. NetTool kombinuje testy kabelu, sítě a konfigurace počítače do jednoho malého zařízení, takže budete moci rychle vyřešit jakýkoli, i ten nejtěžší, problém s konektivitou.
