Ubuntu appears to never be properly tested with HP BIOS. When an OS triggers a high temp alarm, one of the first things it does is shut down the USB ports. Learned that the hardware while working on an iteration of IPOS for the marketing agency which had it. Go to lunch, come back, neither mouse nor keyboard would work. Took days until out of frustration I hooked up a PS\/2 keyboard and mouse.<\/p>\n\n\n\n<p>The whole temperature monitoring thing built into the Linux kernel is just sad. If someone finds documentation of how to tweak the &#8220;default&#8221; max temperature please let me know and I will update this post. Intel designed this CPU to run at 85c under full load. Do not trigger high temperature alarms at 35c. According to <a href=\"https:\/\/forums.tomshardware.com\/threads\/i5-3470-temp-gets-above-80-degrees.3441363\/\">Tom&#8217;s Hardware<\/a>, the throttle temp for this processor is 105c.<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>If it hasn&#8217;t happened to you yet, you must have a wired network connection because posts about Ubuntu&#8217;s disappearing wifi are all over the Internet.

He quickly became a consultant and president of Logikal Solutions, a software consulting firm specializing in OpenVMS application and C++\\\/Qt touchscreen\\\/embedded Linux development. Early in his career he became involved in what is now called cross platform development. Given the dearth of useful books on the subject he ventured into the world of professional author in 1995 writing the first of the \\\"Zinc It!\\\" book series for John Gordon Burke Publisher, Inc. A decade later he released a massive (nearly 800 pages) tome \\\"The Minimum You Need to Know to Be an OpenVMS Application Developer\\\" which tried to encapsulate the essential skills gained over what was nearly a 20 year career at that point. From there \\\"The Minimum You Need to Know\\\" book series was born. Three years later he wrote his first novel \\\"Infinite Exposure\\\" which got much notice from people involved in the banking and financial security worlds. Some of the attacks predicted in that book have since come to pass. While it was not originally intended to be a trilogy, it became the first book of \\\"The Earth That Was\\\" trilogy: Infinite Exposure Lesedi - The Greatest Lie Ever Told John Smith - Last Known Survivor of the Microsoft Wars When he is not consulting Roland Hughes posts about technology and sometimes politics on his blog. He also has regularly scheduled Sunday posts appearing on the Interesting Authors blog.\",\"sameAs\":[\"https:\\\/\\\/theminimumyouneedtoknow.com\"],\"url\":\"https:\\\/\\\/www.logikalsolutions.com\\\/wordpress\\\/author\\\/seasoned_geek\\\/\"}]}<\/script>\n<!-- \/ Yoast SEO plugin. -->","yoast_head_json":{"title":"Ubuntu Disappearing Wifi &#8211;

He quickly became a consultant and president of Logikal Solutions, a software consulting firm specializing in OpenVMS application and C++\/Qt touchscreen\/embedded Linux development. Early in his career he became involved in what is now called cross platform development. Given the dearth of useful books on the subject he ventured into the world of professional author in 1995 writing the first of the \"Zinc It!\" book series for John Gordon Burke Publisher, Inc. A decade later he released a massive (nearly 800 pages) tome \"The Minimum You Need to Know to Be an OpenVMS Application Developer\" which tried to encapsulate the essential skills gained over what was nearly a 20 year career at that point. From there \"The Minimum You Need to Know\" book series was born. Three years later he wrote his first novel \"Infinite Exposure\" which got much notice from people involved in the banking and financial security worlds. Some of the attacks predicted in that book have since come to pass. While it was not originally intended to be a trilogy, it became the first book of \"The Earth That Was\" trilogy: Infinite Exposure Lesedi - The Greatest Lie Ever Told John Smith - Last Known Survivor of the Microsoft Wars When he is not consulting Roland Hughes posts about technology and sometimes politics on his blog. He also has regularly scheduled Sunday posts appearing on the Interesting Authors blog.","sameAs":["https:\/\/theminimumyouneedtoknow.com"],"url":"https:\/\/www.logikalsolutions.com\/wordpress\/author\/seasoned_geek\/"}]}},"_links":{"self":[{"href":"https:\/\/www.logikalsolutions.com\/wordpress\/wp-json\/wp\/v2\/posts\/7364","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.logikalsolutions.com\/wordpress\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.logikalsolutions.com\/wordpress\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.logikalsolutions.com\/wordpress\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.logikalsolutions.com\/wordpress\/wp-json\/wp\/v2\/comments?post=7364"}],"version-history":[{"count":1,"href":"https:\/\/www.logikalsolutions.com\/wordpress\/wp-json\/wp\/v2\/posts\/7364\/revisions"}],"predecessor-version":[{"id":7629,"href":"https:\/\/www.logikalsolutions.com\/wordpress\/wp-json\/wp\/v2\/posts\/7364\/revisions\/7629"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.logikalsolutions.com\/wordpress\/wp-json\/wp\/v2\/media\/7204"}],"wp:attachment":[{"href":"https:\/\/www.logikalsolutions.com\/wordpress\/wp-json\/wp\/v2\/media?parent=7364"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.logikalsolutions.com\/wordpress\/wp-json\/wp\/v2\/categories?post=7364"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.logikalsolutions.com\/wordpress\/wp-json\/wp\/v2\/tags?post=7364"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
