Hi there
I recently got three TP-Link Deco M5 mesh units to fix the wifi black spots in the house. I'd seen the advice on here that it's unwise to have both the Hub 3 and the Decos working as DHCP routers and that your choice is either Hub as router and Decos as APs, but it's better with Hub in modem mode and Deco as router.
So, I did what I thought I needed to do- moved the Hub to modem mode and let it reboot to show a magenta light, expecting the Deco, already set up as a router, to have connection. Nothing happened (other than the Deco light turning red), and worse, I couldn't get into the 192.168.100.1 page (or indeed 0.1) on the laptop plugged in directly to the Hub, so I couldn't move it back to router mode. I could only manage that by phoning Virgin and getting them to do it, but they didn't offer any corrective advice.
Am I doing something wrong? I'd seen that on older hubs, only ethernet port 1 is usable for connecting devices, but I tried every port anyway, to no avail. I'm wondering if my hub is possibly faulty.
Cheers
Scott
