Place your router in a central location, away from obstructions and interference. You can also consider using Wi-Fi extenders or Mesh routers to extend your coverage.

Intermittent connectivity can be caused by interference, outdated firmware, or network congestion. Try updating your router's firmware and reducing interference from other devices. SUNNY-NET Online Support Request - Japan Should the problem persist, inspect the NTT modem's LED lamps for their status. A loss of lights during internet downtime suggests a potential fiber line issue. In such cases, promptly open a trouble ticket with us for resolution. *Important note: If the fiber line falls outside Sunny-Net's jurisdiction, please reach out to NTT directly, providing the NTT customer ID or billing ID of the fiber line. (NTT English support: 0120-064-337)

Check for any loose cables, update your router's firmware, and ensure your devices are within range of the router. If the issue continues, open a trouble ticket. SUNNY-NET Online Support Request - Japan

We will provide you with a router that fully supports IPoE and is optimized for our service. However, if you choose to purchase a wireless router, please ensure it meets the following minimum specifications: Dual-band Wi-Fi (2.4GHz and 5GHz): Dual-band routers can operate on both frequency bands, which helps reduce interference and improves overall network performance. The 2.4GHz band offers better range, while the 5GHz band provides higher speeds and less interference. Wi-Fi 6 (802.11ax): If possible, opt for a router with Wi-Fi 6 support. Wi-Fi 6 offers several advantages over previous standards like Wi-Fi 5 (802.11ac), including higher data transfer rates, improved efficiency in crowded environments, and better battery life for connected devices. This is particularly beneficial for households with many devices or high-bandwidth activities. Gigabit Ethernet ports: For high-speed wired connections, which are important for tasks that require stable and fast internet, such as gaming or streaming in 4K. MU-MIMO technology: Multi-User Multiple Input Multiple Output (MU-MIMO) allows the router to communicate with multiple devices simultaneously, enhancing network efficiency and speed. At least AC2200 speed rating: Provides sufficient speed for most household internet needs. However, routers with Wi-Fi 6 (AX) typically offer better performance and future-proofing compared to AC models. We generally recommend TP-Link routers for their reliability and ease of setup. We advise against Linksys and NETGEAR routers due to their more complex initial setup requirements. If you have any questions or need further assistance, please don't hesitate to reach out.

SUNNY-NET Co., Ltd. is a leading internet service provider in Japan, offering a range of services including broadband, VPN, pocket Wi-Fi, and streaming solutions in collaboration with NTT East and NTT West.

Installation typically takes 2-4 weeks after the order is confirmed, depending on the availability of NTT for the physical connection. If the location where you're requesting internet service doesn't have an existing fiber line, the installation may take more than four weeks. Fortunately, we will supply a complimentary temporary pocket Wi-Fi device for your use during this period.

IPoE (Internet Protocol over Ethernet) is a high-speed internet connection method that does not require PPPoE authentication, providing more stable and faster connections.

IPoE offers lower latency and higher speeds compared to traditional PPPoE connections, making it ideal for streaming, gaming, and other high-bandwidth activities.

Not all routers are compatible with IPoE. If you're considering buying a router, make sure it supports IPoE (tranSix) to achieve the best performance.

Internet speeds may fluctuate due to location and network congestion. However, our fiber optic internet services typically deliver the following speeds: - neXtreme Internet service: 100-550 Mbps - SN-Hikari Internet service: 50-150 Mbps *Important note: Speed test results can vary depending on the speed test server's location. Additionally, tests conducted over a wireless network may not be accurate due to various uncontrollable factors. For the most precise results, it is highly recommended to disable all VPN services and to perform speed tests using an Ethernet cable connected directly to the home gateway device provided by SUNNY-NET.
