This is a defective Speed Wi-Fi L13. It takes a very long time to start up, and the procedure is complicated. When the power is connected, it will not start or be usable unless the WPS button is pressed. Also, it may suddenly restart, making it very unstable. - There are no restrictions on network usage. I tried to update the device's software, but it failed. This product is a UQ WiMAX device, and because it was using a Rakuten Mobile SIM (mobile data), that may be the reason for the update failure. • Due to the defect, it is being sold at a low price. • Not recommended for beginners. For those who can repair it, or for parts or those with knowledge. • Accessories: Main unit + genuine power adapter • No returns or exchanges are accepted, so please consider carefully before purchasing. Thank you for viewing.
