If you're able to access router via SSH you it should be possible to do so via WebUI as well. With 7.0 there's an issue with WebUI services and for some reason it becomes not responsive. For those cases you can simply restart WebUi services using command "/etc/init.d/uhttpd restart" or if you enter command "ps" and see that there's no uhttpd services running "/etc/init.d/uhttpd start" should start the services. Another thing is worth looking at is whether the default WebUI ports were changed or HTTP(S) access saw disabled at all. For that use command "cat /etc/config/uhttpd" to check config and "vi /etc/config/uhttpd" to change the config.After configuration is changed, don't forget to use "/etc/init.d/uhttpd restart" to restart the services and apply the changes.
