But usually, we use DHCP.<\/p><p>For cellular connectivity, it\u2019s available in a choice of high-speed networks Cat 6, Cat 4, low and medium-speed networks (cat1 and Cat M) as well as NarrowBand network NB-IOT.\u00a0<\/p><p>Wireless Wi-Fi network which can be configured as STA mode and then connects to the SSID that can be scanned nearby.<\/p><p>let\u2019s go further with the Reliability. Here comes the multi-layer mechanism.<\/p><p>\u00a0<\/p><p>Within the single link like cellular connectivity, it basically has dual SIM failover, The main purpose of dual-Sim is to provide failover between different operator networks.<\/p><p>Between the wired, Wi-Fi and cellular connection, there is Link Backup, and that keeps you always online because it provides you with hot backup and load balancing. Once the main link is down, the backup link is automatically switched.<\/p><p>VRRP provides a better option among the two networking devices. It groups multiple devices into a virtual device, whose IP address is configured as the default gateway address to back up the default gateway. If a gateway fails, VRRP elects a different gateway to forward traffic, thereby ensuring reliable network communication. When the master device fails, the traffic destined for the default gateway is forwarded by the backup device.<\/p><p>\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d6e3a4d elementor-widget elementor-widget-image\" data-id=\"d6e3a4d\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"1400\" height=\"525\" src=\"https:\/\/www.inhand.com\/wp-content\/uploads\/2026\/03\/IR615-S-Failover.png\" class=\"attachment-full size-full wp-image-960027\" alt=\"IR615-S router highlighting its failover features for network reliability and redundancy.\" srcset=\"https:\/\/www.inhand.com\/wp-content\/uploads\/2026\/03\/IR615-S-Failover.png 1400w, https:\/\/www.inhand.com\/wp-content\/uploads\/2026\/03\/IR615-S-Failover-300x113.png 300w, https:\/\/www.inhand.com\/wp-content\/uploads\/2026\/03\/IR615-S-Failover-768x288.png 768w, https:\/\/www.inhand.com\/wp-content\/uploads\/2026\/03\/IR615-S-Failover-18x7.png 18w, https:\/\/www.inhand.com\/wp-content\/uploads\/2026\/03\/IR615-S-Failover-600x225.png 600w\" sizes=\"(max-width: 1400px) 100vw, 1400px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-1e87d53 e-con-full e-flex e-con e-child\" data-id=\"1e87d53\" data-element_type=\"container\">\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-a14c13b e-con-full anli_l_st e-flex e-con e-child\" data-id=\"a14c13b\" data-element_type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;,&quot;sticky&quot;:&quot;top&quot;,&quot;sticky_offset&quot;:90,&quot;sticky_effects_offset&quot;:100,&quot;sticky_anchor_link_offset&quot;:100,&quot;sticky_parent&quot;:&quot;yes&quot;,&quot;sticky_on&quot;:[&quot;desktop&quot;,&quot;tablet&quot;,&quot;mobile&quot;]}\">\n\t\t<div class=\"elementor-element elementor-element-1da7e082 e-con-full e-flex e-con e-child\" data-id=\"1da7e082\" data-element_type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t<div class=\"elementor-element elementor-element-69473ed elementor-widget elementor-widget-heading\" data-id=\"69473ed\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Read More <\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-108ac635 elementor-widget elementor-widget-shortcode\" data-id=\"108ac635\" data-element_type=\"widget\" data-widget_type=\"shortcode.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-shortcode\">    <style>\n        \/* --- \u8fd9\u91cc\u7684\u53c2\u6570\u5168\u90e8\u4fdd\u7559\u4f60\u7684\u4fee\u6539 --- *\/\n        .vpro-wrapper {\n            width: 100%;\n            max-width: 25rem;\n            height: 38.5rem;\n            overflow-y: auto;\n            overflow-x: hidden;\n            \/* 1. \u589e\u52a0\u5e95\u90e8\u5185\u8fb9\u8ddd\uff0c\u5236\u9020\u865a\u7a7a\u611f *\/\n            padding: 0.3125rem 0.3125rem 0rem 0.3125rem;\n            scrollbar-width: thin;\n            box-sizing: border-box;\n        }\n\n        .vpro-wrapper::-webkit-scrollbar { width: 0.25rem;
