ヨアン 3 This product is very slow, I compared directly to softbank bb modem and the speed is not reached the compromised.First, the speed always drop in the night time around 1900-2430. The speed around 5 Mbps. However, when I changed to softbank bb router, the speed become 70-100 Mbps.I thought it is because of the firmware, but everything is updated and no problem. The problem occurs every night.In the day time, the product will show 100 Mbps. However, when compared to Softbank it will show 200 Mbps.We are not happy buying this product and we will return this product because of malfuction. We believe this product have some defect.
