[DLS-140](https://go.skytrac.ca/knowledge/transceivers-and-hardware#dls-140) # How do I factory reset my DLS-140, and what does it clear? **Before you reset:** Download a copy of the configuration. Note any custom Wi-Fi name, password or APN. Check whether the aircraft uses a configuration we supplied. Make sure you can log in, because the reset is only done from the web interface. **After the reset:** 1. Reconnect to the default Wi-Fi (DLS-140-serial number, password skytrac!). 2. Log in with skytrac / skytrac. 3. Upload the saved or supplied configuration file. 4. Check routing, firewall and that both connections are enabled. 5. If the DLS-140 works with an ISAT-200A, check the ISAT-200A web page still opens at 192.168.111.120. **What it clears:** Wi-Fi name, password and security, APN, routing, firewall, network address and DHCP, reserved addresses, device name, and any configuration file we supplied. **What it doesn't clear:** Logs, firmware, service activation, serial number, IMEI and SIM details, and anything on the ISAT-200A. **Should I reset to fix a problem?** Not without direction from Skytrac. Because logs survive a reset, we can still see what happened beforehand if it is done, but most problems should not be responded to by resetting without a specific reason. - [Flight Following and Account Management](https://go.skytrac.ca/knowledge/flight-following-and-account-management#main-content) - [TrooTrax](https://go.skytrac.ca/knowledge/flight-following-and-account-management#trootrax) - [SkyWeb](https://go.skytrac.ca/knowledge/flight-following-and-account-management#skyweb) - [WebSentinel](https://go.skytrac.ca/knowledge/flight-following-and-account-management#websentinel) - [Asset Manager](https://go.skytrac.ca/knowledge/flight-following-and-account-management#asset-manager) - [Transceivers and Hardware](https://go.skytrac.ca/knowledge/transceivers-and-hardware#main-content) - [ISAT-200A](https://go.skytrac.ca/knowledge/transceivers-and-hardware#isat-200a) - [SkyNode S100 and S200](https://go.skytrac.ca/knowledge/transceivers-and-hardware#skynode-s100-and-s200) - [DZMx](https://go.skytrac.ca/knowledge/transceivers-and-hardware#dzmx) - [RockAIR](https://go.skytrac.ca/knowledge/transceivers-and-hardware#rockair) - [Sky Connect Trackers](https://go.skytrac.ca/knowledge/transceivers-and-hardware#sky-connect-trackers) - [DLS-140](https://go.skytrac.ca/knowledge/transceivers-and-hardware#dls-140) - [IONode](https://go.skytrac.ca/knowledge/transceivers-and-hardware#ionode) - [SKYTRAC Mobile](https://go.skytrac.ca/knowledge/skytrac-mobile) - [General Troubleshooting & FAQ](https://go.skytrac.ca/knowledge/general-troubleshooting-faq) - [Activation and Deactivation](https://go.skytrac.ca/knowledge/activation-and-deactivation) - [Installation Manuals](https://go.skytrac.ca/knowledge/installation-manuals) - [Cockpit dialers and displays](https://go.skytrac.ca/knowledge/cockpit-dialers-and-displays#main-content) - [CDP-300 and DVI-300](https://go.skytrac.ca/knowledge/cockpit-dialers-and-displays#cdp-300-and-dvi-300) - [MMU-II](https://go.skytrac.ca/knowledge/cockpit-dialers-and-displays#mmu-ii) - [Contacting SKYTRAC](https://go.skytrac.ca/knowledge/contacting-skytrac#main-content) - [Technical Support](https://go.skytrac.ca/knowledge/contacting-skytrac#technical-support) - [Sales](https://go.skytrac.ca/knowledge/contacting-skytrac#sales) - [Billing](https://go.skytrac.ca/knowledge/contacting-skytrac#billing) - [Aftermarket](https://go.skytrac.ca/knowledge/contacting-skytrac#aftermarket) [![SKYTRAC Logo-White](https://go.skytrac.ca/hs-fs/hubfs/SKYTRAC%20Logo-White.png?width=170&height=31&name=SKYTRAC%20Logo-White.png "SKYTRAC Logo-White")](https://www.skytrac.ca) Technical Support [support@skytrac.ca](mailto:support@skytrac.ca) [+1 250 765 2393](tel:+12507652393) Answered 24/7 Aftermarket and RMAs [aftermarket@skytrac.ca](mailto:aftermarket@skytrac.ca) Repairs and warranty Billing [ar@skytrac.ca](mailto:ar@skytrac.ca) Invoices and payments Sales [sales@skytrac.ca](mailto:sales@skytrac.ca) Quotes and orders Popular Topics [Flight following](https://go.skytrac.ca/knowledge/flight-following-and-account-management) [Hardware](https://go.skytrac.ca/knowledge/transceivers-and-hardware) [Activations](https://go.skytrac.ca/knowledge/activation-and-deactivation) [SKYTRAC Mobile](https://go.skytrac.ca/knowledge/skytrac-mobile) Resources [Documentation Center](https://www.skytrac.ca/resources/documents/) [Videos](https://www.skytrac.ca/resources/videos/) [Webinars](https://www.skytrac.ca/resources/webinars/) [Certifications](https://www.skytrac.ca/company/certifications/) News and Media [Press releases](https://www.skytrac.ca/resources/press/) [Case studies](https://www.skytrac.ca/resources/case-studies/) [White papers](https://www.skytrac.ca/resources/white-papers/) [Magazine](https://www.skytrac.ca/resources/magazine/) Connect [LinkedIn](https://ca.linkedin.com/company/skytracsystems) [Facebook](https://www.facebook.com/SKYTRAC-Systems-Ltd-344178569011082/) [X](https://twitter.com/skytracsystems) [YouTube](https://www.youtube.com/channel/UCQedmJEZf8TvepEuDm9W3tQ) Copyright © 2026 SKYTRAC Systems Ltd.
