Hi
We're providing a free pubic-access WiFi network against ads using MIKROTIK RB951 UI
actually Users select the WiFi hotpsot in Settings and the captive network assistant for apple or the "sign into network wifi" for android open the micro-browser to display our spalsh
the microbrowsers are limited and they didnot support many features like video, landscape, no redirection...the quality of image is not the same VS safari, chrome or firefox

how can i force the devices to open safari, chrome or firefox instead of microbrowsers and ignore captive network assistant for apple or the "sign into network wifi"

some forums speak about firewall the following link:

can you help me to resolve this issue

Thanks

>how can i force the devices to open safari, chrome or firefox instead of microbrowsers< You can not.
As it is a functionality of the users device. However, you can switch to the philosophy, that user has to _explicitly_ open the browser to connect to the WiFi. _And_ you need to fake the internet connection then, _not_ to open the microbrowser automatically and to suppress the small pop-ups.
I did that for several hotspotsystems, based on openwrt/LEDE: Which is much more suited for hotspot systems with special requirements (like yours and mines) compared to MT.
