A low MTU setting might cause issues when loading data-intensive webpages, potentially triggering errors like ERR_SSL_BAD_RECORD_MAC_ALERT in Chrome. This happens because a smaller MTU leads to the fragmentation of data packets, which can disrupt SSL communications.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">To increase your router&#8217;s MTU:<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Check your router&#8217;s manual or the label on the router for the correct IP address.<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Open a web browser and enter the router&#8217;s IP address into the address bar.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Press Enter to access the router&#8217;s login page.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Enter the username and password.

If this doesn&#8217;t help, move on to adjusting settings in your router, particularly the MTU settings, and review configurations in any network optimization tools you might be using. For browser-related issues, tweaking browser settings can also be effective. If these steps don&#8217;t resolve the problem, it may be helpful to consult a technology expert for a more tailored solution. Additionally, regularly updating your software and drivers is a good practice to prevent similar issues in the future.<\/span><br \/>\n\r\n<style>\r\n  #ctablocks_inline_90{\r\n          background-color: #000000;\r\n        color: #ffffff;\r\n    border-radius: 6px;\r\n  }\r\n\r\n  #ctablocks_inline_90 p{\r\n    color: #ffffff;\r\n  }\r\n  #ctablocks_inline_90 .button{\r\n        background-color: rgb(51,57,241);\r\n      color: #ffffff;\r\n    border-color: #3339f1 !important;\r\n  }\r\n  #ctablocks_inline_90 .button:hover{\r\n    background: rgba(51,57,241,0.8);\r\n    color: #ffffff;\r\n    opacity: 1;\r\n  }\r\n        #ctablocks_inline_90 .ctablocks_content_info p {\r\n        padding-left: 36px;\r\n      }\r\n      #ctablocks_inline_90 .ctablocks_content_button {\r\n          margin-left: 37px;\r\n      }\r\n  @media screen and (min-width: 768px) and (max-width: 1260px) {\r\n      #ctablocks_inline_90 .ctablocks_content_button {\r\n          margin-left: 37px !important;\r\n      }\r\n  }\r\n  ;\r\n<\/style>\r\n<div id=\"ctablocks_inline_90\" class=\"ctablocks_container inline_type\r\n        \">\r\n\r\n  <div class=\"ctablocks_content clear\">\r\n    <div class=\"ctablocks_content_info\">\r\n      \r\n            <div class=\"title-wrap\">\r\n\t\t\t\t\t                  <img decoding=\"async\" src=\"https:\/\/10web.io\/blog\/wp-content\/uploads\/sites\/2\/2024\/04\/info-icon-cta.png\" alt=\"Say goodbye to website errors\" title=\"Say goodbye to website errors\">\r\n\t\t\t\t\t            <h4>Say goodbye to website errors<\/h4>\r\n        <\/div>\r\n              <p>Achieve peace of mind with 99.99% uptime on 10Web Managed <br>WordPress Hosting, powered by Google Cloud. <\/p>\r\n          <\/div>\r\n    <div class=\"ctablocks_content_button\">\r\n              <a href=\"https:\/\/10web.io\/ai-website-builder\/\" class=\"button\" data-gtag=\"sign-up-blog\" data-buttontype=\"sign-up\" data-gtag=\"cta-90\" data-buttontype=\"cta-inline\"\r\n\t        >Learn How<\/a>\r\n            \r\n    <\/div>\r\n  <\/div>\r\n    <\/div>\r\n\r\n<style>\r\n  #ctablocks_scrollbox-with-icon_89{\r\n            color: #ffffff;\r\n    border-radius: 6px;\r\n  }\r\n\r\n  #ctablocks_scrollbox-with-icon_89 p{\r\n    color: #ffffff;\r\n  }\r\n  #ctablocks_scrollbox-with-icon_89 .button{\r\n          background-color: rgb(51,57,241);\r\n        color: #ffffff;\r\n    border-color: #3339f1 !important;\r\n  }\r\n  #ctablocks_scrollbox-with-icon_89 .button:hover{\r\n    background: rgba(51,57,241,0.8);\r\n    color: #ffffff;\r\n    opacity: 1;\r\n  }\r\n  #ctablocks_scrollbox-with-icon_89.ctablocks_container {\r\n    left: 100%;\r\n  }\r\n  @media screen and (max-width: 1300px) {\r\n      #ctablocks_scrollbox-with-icon_89.ctablocks_container {\r\n          left: 0;\r\n          margin: 0 auto;\r\n      }\r\n  }\r\n  #ctablocks_scrollbox-with-icon_89 .ctablocks_content {\r\n      background-color: #000000;\r\n  }\r\n<\/style>\r\n<div id=\"ctablocks_scrollbox-with-icon_89\" class=\"ctablocks_container scrollbox-with-icon_type\r\n      \">\r\n\r\n  <div class=\"ctablocks_content clear\">\r\n    <div class=\"ctablocks_content_info\">\r\n              <h4>Say goodbye to website errors<\/h4>\r\n        <h4 class=\"mobile-title\">Fix all the website errors in one click<\/h4>\r\n              <p>Migrate your website to the world's best Managed WordPress Hosting.<\/p>\r\n          <\/div>\r\n    <div class=\"ctablocks_content_button\">\r\n              <a href=\"https:\/\/10web.io\/ai-website-builder\/\" class=\"button\" data-gtag=\"sign-up-blog\" data-buttontype=\"sign-up\" data-gtag=\"cta-89\" data-buttontype=\"cta-scrollbox-with-icon\"\r\n\t        >Migrate For Free<\/a>\r\n            \r\n    <\/div>\r\n  <\/div>\r\n    <span class=\"close_ctablocks\">\r\n      <img decoding=\"async\" class=\"close-icon\" src=\"https:\/\/10web.io\/blog\/wp-content\/plugins\/cta-blocks\/assets\/images\/close_w.svg\" class=\"close\">\r\n      <img decoding=\"async\" class=\"floating-icon\" src=\"https:\/\/10web.io\/blog\/wp-content\/uploads\/sites\/2\/2024\/04\/Info-icon_Blog.png\" alt=\"Say goodbye to website errors\" title=\"Say goodbye to website errors\">\r\n<!--      <img decoding=\"async\" class=\"arrow-icon white\" src=\"\/cta-blocks\/assets\/images\/arrow-icon.svg\" class=\"close\">\r\n-->      <img decoding=\"async\" class=\"arrow-icon purple\" src=\"https:\/\/10web.io\/blog\/wp-content\/plugins\/cta-blocks\/assets\/images\/arrow-icon-purple.svg\" class=\"close\">\r\n  <\/span>\r\n<\/div>\r\n<br \/>\n <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Stumbling upon error messages while surfing the web can be quite a hassle, particularly when you encounter obscure ones like the ERR_SSL_BAD_RECORD_MAC_ALERT.
