Covers mounting the SD card, locating or creating the NetworkManager .nmconnection file under /etc/NetworkManager/system-connections/, setting correct file permissions with chmod 600, syncing and unmounting safely, and verifying the new connection using nmap, Angry IP Scanner, ping, or SSH. Tested on a Raspberry Pi 5 running Raspberry Pi OS based on Debian Trixie; noted as possibly inapplicable to setups still using wpa_supplicant.conf. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do I change the Wi-Fi SSID and password on a Raspberry Pi without connecting it to a monitor and keyboard? Remove the microSD card, mount its rootfs partition on a Linux computer, and edit or create a .nmconnection file inside /etc/NetworkManager/system-connections/ with the new ssid and psk values under the [wifi] and [wifi-security] sections. Set file permissions to 600 with chmod, run sync, then unmount and reinsert the card into the Pi. _Developers troubleshooting headless Raspberry Pi setups can find similar hands-on fixes curated on daily.dev._ ### Where does Raspberry Pi OS store Wi-Fi connection profiles when using NetworkManager? Wi-Fi connection profiles are stored as .nmconnection files inside /etc/NetworkManager/system-connections/ on the rootfs partition of the SD card. Each profile file contains sections for [connection], [wifi], [wifi-security], and IP settings, and must be readable only by root with chmod 600 permissions to work correctly. _daily.dev helps hobbyists tracking Linux and Raspberry Pi config details stay prepared for these fixes._ ### Why isn't editing wpa_supplicant.conf enough to fix Wi-Fi on my Raspberry Pi? Recent Raspberry Pi OS releases, including versions based on Debian Trixie, use NetworkManager instead of wpa_supplicant for network configuration, so editing wpa_supplicant.conf has no effect on these systems. Instead, Wi-Fi credentials must be set in a .nmconnection file under /etc/NetworkManager/system-connections/ for the change to take effect. _Staying aware of tooling shifts like this NetworkManager change is easier when following Linux updates on daily.dev._ --- Tags: [#linux](https://daily.dev/tags/linux), [#raspberry-pi](https://daily.dev/tags/raspberry-pi) [View this post on daily.dev](https://daily.dev/posts/how-to-change-raspberry-pi-wi-fi-details-from-the-sd-card-k2bbfmkpl) ```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":"How to Change Raspberry Pi Wi-Fi Details From the SD Card","url":"https://daily.dev/posts/how-to-change-raspberry-pi-wi-fi-details-from-the-sd-card-k2bbfmkpl","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/how-to-change-raspberry-pi-wi-fi-details-from-the-sd-card-k2bbfmkpl"},"datePublished":"2026-09-02T09:18:58.949Z","dateModified":"2026-09-02T09:19:36.021Z","description":"A step-by-step method for reconfiguring a Raspberry Pi's Wi-Fi credentials by editing the SD card directly on a Linux computer, useful when the device has no...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/50b6fde24b6b5fdef4865f93b843cf89?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/50b6fde24b6b5fdef4865f93b843cf89?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"It's Foss","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":"It's Foss","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/582e3faed71842bfb9d3840a787d6700","url":"https://daily.dev/sources/itsfoss"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/how-to-change-raspberry-pi-wi-fi-details-from-the-sd-card-k2bbfmkpl","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"linux,raspberry-pi","timeRequired":"PT4M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"It's Foss","item":"https://daily.dev/sources/itsfoss"},{"@type":"ListItem","position":3,"name":"How to Change Raspberry Pi Wi-Fi Details From the SD Card"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/how-to-change-raspberry-pi-wi-fi-details-from-the-sd-card-k2bbfmkpl#faq","mainEntity":[{"@type":"Question","name":"How do I change the Wi-Fi SSID and password on a Raspberry Pi without connecting it to a monitor and keyboard?","acceptedAnswer":{"@type":"Answer","text":"Remove the microSD card, mount its rootfs partition on a Linux computer, and edit or create a .nmconnection file inside /etc/NetworkManager/system-connections/ with the new ssid and psk values under the [wifi] and [wifi-security] sections.
