Description

Telstra Smart Modem Gen 3 (Cobra XH) Wi-Fi 6 Modem Router

The Telstra Smart Modem Gen 3, model Cobra XH, is a Wi-Fi 6 modem router with a built-in VDSL2/ADSL2+ modem, a Gigabit Ethernet WAN port for NBN connection boxes, four Gigabit LAN ports and an integrated 4G LTE module for mobile backup. It is graded Excellent by Reboot IT in Melbourne and comes with a 12-month warranty from Reboot IT. Please note: the power adapter is not included.

Key Benefits

  • Wi-Fi 6 (802.11ax). 4x4 on both 2.4 GHz and 5 GHz bands.
  • VDSL2 and Ethernet WAN. VDSL2 with vectoring (17a profile), ADSL2+, or a Gigabit Ethernet WAN port.
  • 4G LTE backup. Integrated LTE module (bands 3, 7 and 28) with an external SIM slot.
  • Graded Excellent. Tested, cleaned and graded by Reboot IT in Melbourne.

Performance in Use

The Cobra XH connects to an NBN connection box through its Gigabit WAN port, or directly to a phone line through its VDSL2 or ADSL2+ modem, and shares the connection over Wi-Fi 6 and four Gigabit LAN ports. Two FXS ports take analogue home phones for a VoIP service, and a USB 2.0 port is provided. The integrated 4G LTE module with an external SIM slot can keep a connection running if the fixed line drops. The unit powers on and was tested; it is supplied without its power adapter, so a compatible adapter is needed.

All-in-one Solution for Home Office

I was looking for an in-expensive all-in-one solution for my home office to replace my existing desktop and monitor. I found this EliteOne 800 on reboot IT for under $200. I wasn't sure what to expect. It arrived within two days!!!! I upgraded the RAM, replaced the HDD and installed Windows 11. This is unbeatable value and was the cheapest price online. Coupled with a 3-month warranty, Reboot IT are by far the best online refurbished retailer I have used. Awesome!
