Cisco 1921 vs. Cisco 1941 vs. Cisco 1941W

Cisco 1900 Routers are designed to meet the application demands of today’s small branches and to evolve to cloud-based services. They took over Cisco 1800 series becoming the most popular Cisco router today.

Cisco 1900 Series ISR include:

  • 2 RU and 1 RU units with up to 2 GE integrated WAN ports
  • Up to 1 Integrated Service Module (ISM)
  • Up to 11 LAN switch ports, two Enhanced High-Speed WAN Interface Card slots
  • Hardware accelerated DES, 3DES and AES for IPSec and SSL VPNs
  • Integrated 802.11a/g/n access point with 802.11i, WPA and WPA2 for security
  • 16 Wireless VLANs and 15 SSIDs
  • WAN optimization through WAAS Express
  • Secure cloud access with integrated intrusion prevention, content filtering and cloud web security
