and the wider network. How you configure it affects security, speed, reliability and how easy it is to troubleshoot problems. Small mistakes at the router level can create big headaches later, so it&#8217;s worth following sensible rules from the start.<\/p>\n<p><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Basic_setup_steps_to_get_right\"><\/span>Basic setup steps to get right<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><\/p>\n<p>These are the essentials you should do during initial setup or when bringing a router into production.<\/p>\n<p><\/p>\n<ul><\/p>\n<li>Change default admin credentials to a strong, unique password and a non-standard username if possible.<\/li>\n<p><\/p>\n<li>Set the correct time zone and enable NTP so logs have accurate timestamps.<\/li>\n<p><\/p>\n<li>Assign a clear IP addressing plan (static address for the router, DHCP range and exclusions, documented subnets).<\/li>\n<p><\/p>\n<li>Disable unused services such as Telnet, WPS or unused ports in the router GUI.<\/li>\n<p><\/p>\n<li>Set a <a href=\"https:\/\/hostadvice.com\/blog\/domains\/difference-between-hostname-and-domain-name\/\" target=\"_blank\" rel=\"noopener\">hostname<\/a> and description that identifies the device and location for easier management.<\/li>\n<p>\n  <\/ul>\n<p><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Security_best_practices\"><\/span>Security best practices<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><\/p>\n<p>Security should be the first priority.
