Guest network works for all devices except android phones

persephone · May 28, 2026, 2:47pm

(Title changed for clarity)
I have set up a guest network. I can connect to the guest network and the internet on 2 rokus, a laptop and a pc without issue. Three different cell phones (all android, various models) connect to the guest network, nut receive a message "Connect to network but no internet access"

The same cell phones are able to access internet if they connect to the default wireless channels.

I can't find any posts or anything on the internet with this specific problem, so I'm sure I've done something wrong. Any help would be greatly appreciated.

For starters try to set wireless security to WPA2 + CCMP instead of SAE mixed

persephone · May 28, 2026, 3:13pm

Thank you, I actually did this, as well as disabling the password altogether. It does not matter. The phones will connect to the network, be assigned an IP, etc, but are not able to access the internet.

When you change the dnsmasq listening port, the DNS server address must be specified in each pool section using DHCP option 6.

uci add_list dhcp.puddlejumper5.dhcp_option='6,192.168.5.1'
uci commit dhcp
service dnsmasq restart

persephone · May 28, 2026, 3:18pm

Thank you, that did it! (Edit: everything works perfectly!) I'm curious, do you happen to know why this would not have affected any of my other devices?

pavelgl · May 28, 2026, 3:30pm

The only explanation I have is that the browsers used on the other devices have hardcoded DNS settings or use DoH/DoT.

persephone · May 28, 2026, 3:32pm

Thanks, I think the rokus are hardcoded, at least. I really appreciate your time and help.
