I have bought Tp-Link Deco S7 about a week ago. It is a 3 pieces set, first satellite is the main one, then second one is connected wireless and the third one is connected throught ethernet backhaul throught unmoderated swtich Tp-Link TL-SG1005D. The problem is that even though internet is still working, main satellite is shining red and other two satellites is blinking red. After I do restart of all satellites, it is ok for about half a day and then again. Software is updated, set as dynamic IP and application is saying, that everything is fine. What seems to be the problem? Thank you
