Avoid ISP Routers

Using routers provided by Internet Service Providers (ISPs) is generally discouraged due to various security concerns. ISP routers often come with default passwords, indicating a lack of attention to security. They are typically configured for convenience rather than security, which can lead to vulnerabilities. ISPs may also implement backdoors in their devices, potentially allowing unauthorized access. Additionally, ISP-provided routers are prime targets for hackers due to their widespread use, making them more susceptible to attacks.

Many ISPs restrict users from changing critical settings, such as DNS servers or firmware updates, which can further compromise security. There have been numerous incidents where ISPs failed to address security flaws in their routers, leaving millions of devices exposed. For example, Sky routers in the UK had a significant DNS rebinding flaw that took 18 months to fix, and Virgin Media left users vulnerable for over two years.

Moreover, ISPs often charge rental fees for their equipment, making it financially sensible for users to invest in their own routers and modems. This not only provides better security but also allows for greater control over the device's settings and updates. Overall, purchasing independent hardware is recommended for enhanced security and reliability in home networking.
