Our organization's building has (internal) flint walls which effectively blocks wi-fi and 4g.
For this reason, we have an internal 48-port ethernet network delivering wired internet to most rooms.
Nevertheless, we need good wi-fi for our guests and visitors.
I tried to resolve this February 2019. We tested adding a wifi router from BT to the network via a local ethernet port.
The network crashes. DHCP (internal system IP address allocation) is conflicted. We attached an ethernet cable to the wifi router on a laptop, and reset it's preferred IP address (from the default 192 range), reboot login to check new config. We then attached the reconfigured wifi device to the BTHub6 ethernet system, and it crashed the network.
I called BT technical support, elevated the issue to a (helpful and knowledgable) specialist who didn't have a viable solution, although he had used an ethernet-through-mains-electric-circuit configuration to address a similiar problem.
Perhaps BTHub6 (Huawei) router software has been now been updated to accomodate wi-fi subnets ?
Is ther any other solution out there so we can simply buy the wifi routers of our choice and use them on our business network ? Thank you for your attention.
