| Problem | Likely Cause | Solution | | :--- | :--- | :--- | | (Power light flashes endlessly) | Wrong firmware version or corrupt upload | Use Method B (TFTP) with the original correct firmware . If that fails, you need a JTAG or serial console recovery (advanced). | | No Internet after Update | VLAN IDs or LOID erased | Log in, go to WAN Configuration . Re-enter your ISP’s VLAN (e.g., 101 for data, 102 for VoIP). Call your ISP for the LOID password. | | Wi-Fi Missing (No 5GHz) | Firmware lacks drivers for your radio chip | Downgrade to your previous working firmware. This is a hardware mismatch. | | VoIP (Phone) Dead | SIP server details erased or protocol changed (SIP vs H.248) | Manually reconfigure from your ISP’s old settings backup. | | Admin Password Not Working | Firmware reset to default user/pass | Try root/admin , admin/admin , telecomadmin/admintelecom . If none work, use the physical reset button for 30 seconds. |
