HaLowLink 1 is Morse Micro's Wi-Fi HaLow (802.11ah) access point and extender platform, designed for long-range, low-power IoT connectivity. The software runs on OpenWrt and is managed through the device's web-based user interface. Release 2.11.13 addresses security compliance improvements by updating the MM6108 driver and firmware (1.17.8 → 1.17.9). Customers running v2.11.12 are encouraged to upgrade. To upgrade your device, navigate to the Upgrade page in the web UI. An active internet connection is required. ## 2 Software Change Summary ### 2.1 Release 2.11.13 Release 2.11.13 is a maintenance release for HaLowLink 1 following release v2.11.12. It updates the MM6108 driver and firmware package to version 1.17.9, which fixes the reported security vulnerabilities. There are no new end-user features in this release. #### 2.1.1 New Features * There are no new features in this release. The MM6108 driver and firmware have been updated to version 1.17.9; this update delivers the security improvements described below and introduces no new end-user functionality. * For a full list of MM6108 driver features, refer to the MM6108 Linux Software Release Notes (1.17.9). #### 2.1.2 Resolved Issues and Improvements **2.1.2.1 Security compliance improvements** * Hardened parsing of 802.11 management-frame information elements (IEs) against malformed input: * Added bounds validation for vendor-specific IE lengths, preventing out-of-bounds reads. * Protected against a buffer overflow when parsing the Traffic Indication Map (TIM) information element. * Protected against a buffer overflow when parsing the S1G Capabilities information element. #### 2.1.3 Known Issues All known issues reported in release 2.11.12 are carried forward unchanged into 2.11.13; this release does not resolve any of them. They are listed again below for completeness. **2.1.3.1 Unbalanced downlink distribution in multi-STA scenarios** * In multi-STA setups, an unbalanced downlink distribution may be observed when traffic is sent simultaneously to more than four stations, with the first two associated stations potentially monopolizing the medium. * Workaround: Enable airtime fairness on the HaLowLink 1 (enable\_airtime\_fairness=1). **2.1.3.2 Performance constraints** * UDP throughput over IPv6 is lower than IPv4 when using 4 MHz and 8 MHz channels * In regulatory domains with duty-cycle restrictions (e.g., EU, Japan), MCS10 may not provide usable bandwidth without Burst Mode * Workaround: Enable Burst Mode **2.1.3.3 Networking and protocol behavior** * In rare cases, the STA may associate more slowly than expected and report an “MFP required” error * In rare cases, DPP provisioning may fail and require retry ### 2.2 Release 2.11.12 Release 2.11.12 is the third maintenance release for HaLowLink 1 following release v2.7.6. It includes security compliance updates, stability improvements for high-density deployments, and an upgrade to the MM6108 driver and firmware package (1.14.1 → 1.17.8), bringing cumulative enhancements in performance, reliability, and standards compliance. #### 2.2.1 New Features * Driver and firmware upgrade (1.14.1 → 1.17.8)\ Updated MM6108 driver and firmware package, incorporating multiple enhancements in performance, stability, and standards compliance across intermediate releases. * Scheduled Scan support\ Enables periodic background scanning to improve network discovery and roaming behavior. * Additional driver capabilities (internal enhancements)\ Includes support for features such as improved provisioning workflows, enhanced power management capabilities, and extended platform compatibility introduced across driver releases. For full details, refer to the MM6108 Linux Software Release Notes (v1.17.8). #### 2.2.2 Resolved Issues and Improvements **2.2.2.1 Security compliance improvements** * Updated OpenSSL configuration to meet current security standards, ensuring compatibility with stricter TLS requirements and audit criteria. * Addressed a CWE-125 security weakness. **2.2.2.2 Multi-STA performance** * Multi-STA performance has been improved for up to 8 stations. * Improved buffering and delivery for power-saving and 4-address mode stations * Enhanced stability in high-density deployments: resolved a firmware crash that could occur when operating with 32 or more connected STAs. **2.2.2.3 System stability and performance** * Improved PHY behavior for more stable medium access and link performance * Enhanced Automatic Channel Selection (ACS) * Fixed issues where noise was not measured correctly * Avoids use of disabled or invalid channels * Improved handling of wider channel configurations * Prevents unnecessary disabling of channels due to sub-channel restrictions * Improved QoS behavior: * Fixed excessive transmission of inactivity QoS NULL frames * Improved resilience to QoS priority mismatches * Improved scan and association behavior: * Fixed issues with scan timeouts and standby recovery * Fixed incorrect probe response bandwidth handling * Improved driver stability: * Resolved memory handling issues during hardware restart * Fixed firmware crash scenarios in mesh configurations **2.2.2.4 DPP push-button reliability** * Improved robustness of DPP provisioning workflows, including push-button pairing reliability **2.2.2.5 802.11s Mesh** * Resolved issues affecting multi-hop traffic delivery, including DHCP propagation across mesh nodes * Optimizations to 802.11s mesh routing (HWMP) for improved multi-hop performance * Improved mesh self-healing behavior through default configuration changes * Avoided unnecessary HWMP frame generation when alternative mesh protocols are in use * Fixed issues affecting mesh stability, including crash conditions and traffic forwarding inconsistencies **2.2.2.4 Documentation** * The user guide now lists all open network ports, with justification and usage context for each. #### 2.2.3 Known Issues **2.2.3.1 Unbalanced downlink distribution in multi-STA scenarios** * In multi-STA setups, an unbalanced downlink distribution may be observed when traffic is sent simultaneously to more than four stations, with the first two associated stations potentially monopolizing the medium. * Workaround: Enable airtime fairness on the HaLowLink 1 (enable\_airtime\_fairness=1). **2.2.3.2 Performance constraints** * UDP throughput over IPv6 is lower than IPv4 when using 4 MHz and 8 MHz channels * In regulatory domains with duty-cycle restrictions (e.g., EU, Japan), MCS10 may not provide usable bandwidth without Burst Mode * Workaround: Enable Burst Mode **2.2.3.3 Networking and protocol behavior** * In rare cases, the STA may associate more slowly than expected and report an “MFP required” error * In rare cases, DPP provisioning may fail and require retry ## 3 Revision History | Release Number | Release Date | Release Notes | | -------------- | ------------ | ------------------------------------------ | | Version 2 | 04 Jun 2026 | Third maintenance release OpenWrt 2.11.13 | | Version 1 | 01 May 2026 | Second maintenance release OpenWrt 2.11.12 | Morse Micro provides this information "as is" without warranties of any kind, express or implied.
