At the risk of stating the obvious, I take it you've restarted the router as it needs a reboot to pick up the new settings?
did you use the link I posted then sent email to the consumer email address like I suggested that should get you some action
Yes - I've restarted the router multiple times before, during and after the long chat with the bot, and tried connecting a different phone as well. Nothing made any difference. The bot said there must be a problem with the connection at the exchange, but it couldn't fix this.
