Why does the Seriallink 4G router reboot repeatedly in a few minutes without a card?Our router has the function of hardware and software watchdog by default. When logging on to the router, we can configure a PING host IP address in “Service-Watchcat”. If this IP is not accessible, the router will automatically restart every six minutes. While restarting the router, we will give a hard reset signal to the 4G module to restore Internet access by searching the network from a new way. If you connect to a dedicated intranet (not a big one like Baidu), you need to configure a gateway IP or server IP address to Watchcat to prevent the router from restarting continuously.
How to Insert SIM Card Correctly in the SLK-R4008 4G Router?Firstly, use a sharp object to hold the Yellow button, and then a SIM card tray will be popped up. Secondly, insert a SIM card into the gap angle of the SIM card, ensuring the card core is inserted downward. After the card is plugged in, re-plug the power adapter, and then the router goes into normal working state when starting up.
Whether the Seriallink router supports 800MHZ frequency band of telecom?800MHz frequency is known as the “golden band” in the communication industry. It has long transmission distance and strong penetration ability, which is very important for the construction of 4G network in remote areas. All industrial 4G routers support telecommunications 800 band LTE.
What is 7 modes, 5 modes? What is the difference?Different mobile card operators have different network bands. The 7 modes of 4G router refers to seven different communication network modes supporting GSM, CDMA200 1xRTT, CDMA2000 1xEV-DO, WCDMA, TD-SCDMA, TDD-LTE, and FDD-LTE (2G/3G/4G network of China Mobile, Unicom, Telecommunications). It fits all kinds of networks, which means the cards of the three major operators in China can be used in any network environment. The 5 modes supports TDD-LTE, FDD-LTE, TD-SCDMA, WCDMA, and GSM (China Mobile&Unicom's 4G, 3G and 2G networks, Telecommunication's 4G network). All Seriallink routers are 7 modes products, except customization.
