A couple of weeks ago I bought a Beryl and last week I tried to connect it to a hotels wifi (Premier Inn in the UK). However I just could not get the captive portal up on my phone or laptop via the Beryl (but could directly). I had 2 Android phones with me and a windows laptop. None of these could get the captive portal via the Beryl. I turned off dns rebinding protection, signed into the wifi directly from my laptop then tried cloning the mac address to the Beryl but nothing worked.
I’m using the Beryl in repeater mode and it works fine with my home wifi.
I made some progress with this, this week. Here’s what I discovered:
I could connect to the hotel wifi with our without mac cloning. With mac cloning need to restart router after original device has left the wifi network otherwise there is a mac address conflict (obviously).
To get the hotels captive portal passed through I needed to turn off the nextdns dns profile I had active on the router and use the hotels dns server. I’m assuming that this means anything else from a dns perspective should be turned off until you’ve passed the captive portal.
The wifi blocked port 853 (DoT) so android private dns (nextdns in my case) didn’t work so I had to download and install their app which spoofs a vpn to work instead. I left nextdns turned off on the Beryl.
I had dns rebinding protect turned off, didn’t have the chance to try with it on
My Beryl would only stay connected to the hotel wifi for around 30min before being kicked off. I put this down to a combination of the hotel wifi being poor (1-4 Mpbs ) and the hotel being busy and will try again next time as I stay in the same hotel pretty much on a monthly basis.
The hotel was a Premier Inn in the UK with wifi provided by Virgin Media.
The neverssl link above seemed to be useful as sometimes some devices just can’t find a connection.
