The default username and password are usually found in the instruction manual (common for all devices) or on the device itself. [citation needed] Default passwords are one of the major contributing factors to large-scale compromises of home routers. [1] Leaving such a password on devices available to the public is a major security risk. [2] [3 ...
Some devices with dual-band wireless network connectivity do not allow the user to select the 2.4 GHz or 5 GHz band (or even a particular radio or SSID) when using Wi-Fi Protected Setup, unless the wireless access point has separate WPS button for each band or radio; however, a number of later wireless routers with multiple frequency bands and ...
Linksys manufactures a series of network routers. Many models are shipped with Linux-based firmware and can run third-party firmware. The first model to support third-party firmware was the very popular Linksys WRT54G series. The Linksys WRT160N/WRT310N series is the successor to the WRT54G series of routers from Linksys.
The Linksys WRT54G Wi-Fi series is a series of Wi-Fi–capable residential gateways marketed by Linksys, a subsidiary of Cisco, from 2003 until acquired by Belkin in 2013. A residential gateway connects a local area network (such as a home network ) to a wide area network (such as the Internet ).
A common method is to direct all World Wide Web traffic to a web server, which returns an HTTP redirect to a captive portal. [8] When a modern, Internet-enabled device first connects to a network, it sends out an HTTP request to a detection URL predefined by its vendor and expects an HTTP status code 200 OK or 204 No Content.
Remote management is turned off by default; users can turn on remote management through advanced settings. Firmware fixes are currently available for the affected devices. [32] In 2020, a vulnerability was discovered that affected many Netgear home WiFi routers. The problem was in a web server built into the router's firmware.
Many ISPs register the client's MAC address for service and billing services. [3] Since MAC addresses are unique and hard-coded on network interface controller (NIC) cards, [1] when the client wants to connect a new device or change an existing one, the ISP will detect different MAC addresses and might not grant Internet access to those new devices.
An application-level gateway (ALG, also known as application-layer gateway, application gateway, application proxy, or application-level proxy) is a security component that augments a firewall or NAT employed in a mobile network.
