WiFi black box issues
I have the VM black box router, made by sagecomm.
I am having a peculiar problem. All of a sudden, devices were not connecting to the internet. When I checked on my iPhone, it showed a an IP address starting with 169 which seems like the DHCP is not giving IP addresses. When I manually enter 194 IP address on my phone, and all the other details, it the internet works fine. Same with my firestick. However for other smart devices, not possible to do that.
I have reset the router several times (unplugging everything and holding reset button for longer than 60 seconds) and still the same problem. However the problem seems to occur when I change the SSID name and password.
I contacted VM support and they could not do anything and they sent me a new box about a week and a half ago. All worked fine until yesterday and the same problem is encountered. I called VM support and they were not able to help, escalated it to their IT team.
Anything connect via Ethernet works fine.
Any suggestions?
