Previously Tuned relied on iwpriv by default, but Fedora dropped that package, causing systems to lose out-of-the-box WiFi power savings; the new release switches to using iw instead, which is now also an RPM build dependency, while keeping iwpriv for legacy support. Other changes include raising the AVC cache threshold to 8192 in the network-latency profile (versus the RHEL9/RHEL10 default of 512, which caused latency spikes), improved error messages, more build documentation, systemd integration changes, and additional network coalescing options. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why did Fedora lose out-of-the-box WiFi power savings and how was it fixed in Tuned 2.28? Fedora stopped carrying the iwpriv package, which Tuned relied on by default for enabling WiFi power savings, causing systems to lose this optimization out-of-the-box. Tuned 2.28 fixes this by switching WiFi power management handling to use iw instead, which is now an RPM build dependency for Tuned, while retaining iwpriv support for legacy systems. _Follow tuned power-management changes like this on daily.dev before they surprise you on production Fedora systems._ ### What changed with the AVC cache threshold in Tuned's network-latency profile? Tuned 2.28 raises the AVC cache threshold to 8192 in the network-latency profile. On RHEL9 and RHEL10 the default setting is 512, which has been observed to cause latency spikes for networking workloads, so the higher threshold addresses that issue. _Networking engineers tuning RHEL latency profiles can track fixes like this via daily.dev._ ## Similar posts on daily.dev - [Red Hat Releases Tuned 2.27 For Adaptively Tuning Linux To Different Workloads](https://daily.dev/posts/red-hat-releases-tuned-2-27-for-adaptively-tuning-linux-to-different-workloads-yqhhcnjpf) · Phoronix · 0 upvotes · 0 comments - [Test Days for Fedora 45: Help Us Test the Big Changes](https://daily.dev/posts/test-days-for-fedora-45-help-us-test-the-big-changes-yxwykgv4b) · Fedora Magazine · 0 upvotes · 0 comments - [Linux 7.2 Brings More Work Around WiFi Aware, WiFi 8 / UHR & More Networking Hardware](https://daily.dev/posts/linux-7-2-brings-more-work-around-wifi-aware-wifi-8-uhr-more-networking-hardware-e5jszmref) · Phoronix · 1 upvotes · 0 comments --- Tags: [#linux](https://daily.dev/tags/linux), [#red-hat](https://daily.dev/tags/red-hat), [#fedora](https://daily.dev/tags/fedora) [View this post on daily.dev](https://daily.dev/posts/red-hat-s-tuned-2-28-to-improve-out-of-the-box-wifi-power-savings-on-fedora-ahtt7gu3b) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Red Hat's Tuned 2.28 To Improve Out-Of-The-Box WiFi Power Savings On Fedora","url":"https://daily.dev/posts/red-hat-s-tuned-2-28-to-improve-out-of-the-box-wifi-power-savings-on-fedora-ahtt7gu3b","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/red-hat-s-tuned-2-28-to-improve-out-of-the-box-wifi-power-savings-on-fedora-ahtt7gu3b"},"datePublished":"2026-08-22T10:21:28.872Z","dateModified":"2026-08-22T10:21:52.172Z","description":"Tuned 2.28, Red Hat's tuning profile delivery mechanism for Linux, was released with a fix for WiFi power-savings on Fedora and similar distributions....","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/b0e63ba9de26b19974ab7bd1544c07ef?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/b0e63ba9de26b19974ab7bd1544c07ef?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Phoronix","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Phoronix","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/6a26ba379dd64932830aa0c9803dd7ee","url":"https://daily.dev/sources/phoronix"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/red-hat-s-tuned-2-28-to-improve-out-of-the-box-wifi-power-savings-on-fedora-ahtt7gu3b","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"linux,red-hat,fedora","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Phoronix","item":"https://daily.dev/sources/phoronix"},{"@type":"ListItem","position":3,"name":"Red Hat's Tuned 2.28 To Improve Out-Of-The-Box WiFi Power Savings On Fedora"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/red-hat-s-tuned-2-28-to-improve-out-of-the-box-wifi-power-savings-on-fedora-ahtt7gu3b#faq","mainEntity":[{"@type":"Question","name":"Why did Fedora lose out-of-the-box WiFi power savings and how was it fixed in Tuned 2.28?","acceptedAnswer":{"@type":"Answer","text":"Fedora stopped carrying the iwpriv package, which Tuned relied on by default for enabling WiFi power savings, causing systems to lose this optimization out-of-the-box.
