Hello OpenWrt community,
I've encountered a persistent issue with my Comfast EW72-V2 router regarding the 5GHz WiFi network. After a reboot, the 5GHz WiFi fails to come up, and sometimes, along with this issue, the router also fails to provide DHCP services. Interestingly, a simple reboot resolves both issues temporarily. However, upon subsequent reboots, the same problems recur. I've attempted to address this by testing different firmware versions, including OpenWrt 23.05.2 Stable and 23.05.3 Stable, but unfortunately, both versions exhibited the same issue. It appears that the problem may be related to the loading of the mt7663pr2h_rebb.bin firmware file. Despite trying different firmware versions, the issue persists, suggesting a potential hardware or configuration issue.
Issue Reproduction:
- Reboot the router.
- Observe that the 5GHz WiFi network does not come up.
- Additionally, DHCP services may not be available.
- Reboot the router again to temporarily resolve the issues.
Additional Information:
- Router strong textModel: Comfast EW72-V2
- WLAN Hardware: MT7603BE 2.4GHz 802.11bgn, MT7663BEN 5GHz 802.11ac
- Firmware: OpenWrt 23.05.2 - Stable, 23.05.3 - Stable
- Both firmware versions exhibited the same issue.
I appreciate any insights or assistance in resolving this issue. Thank you.
