DIR-825/ACFEOL EOS
תאור
USB Port
The router is equipped with a USB port for connecting a USB modem, which can be used to establish connection to the Internet. In addition, to the USB port of the router you can connect a USB storage device, which will be used as a network drive, or a printer.
Ethernet WAN
Any Ethernet port of the device can be configured to connect to a private Ethernet line.
Wireless Interface
Using the DIR-825/ACF device, you are able to quickly create a high-speed wireless network at home or in your office, which lets computers and mobile devices access the Internet virtually anywhere (within the operational range of your wireless network). Simultaneous activity of 2.4GHz band and 5GHz band allows performing a wide range of tasks. The router can operate as a base station for connecting wireless devices of the standards 802.11a, 802.11b, 802.11g, 802.11n, and 802.11ac (at the wireless connection rate up to 1167Mbps1).
The router supports multiple functions for the wireless interface: several security standards (WEP, WPA/WPA2), MAC address filtering, WPS, WMM.
In addition, the device is equipped with a button for switching the Wi-Fi network off/on. If needed, for example, when you leave home, you can easily switch the router’s WLAN by pressing the button, and devices connected to the LAN ports of the router will stay online.
Security
The wireless router DIR-825/ACF includes a built-in firewall. The advanced security functions minimize threats of hacker attacks, prevent unwanted intrusions to your network, and block access to unwanted websites for users of your LAN.
Easy Configuration and Update
You can configure the settings of the wireless router DIR-825/ACF via the user-friendly web-based interface (the interface is available in several languages).
Now you can simply update the firmware: the router itself finds approved firmware on D-Link update server and notifies when ready to install it.
