Maybe you upset your modem with the sheer number of asterisks you use in communications lol

There is a post in the BB support area about troubleshooting 169. addresses but if it is due to an account suspension you would never find out unless you call CS. Running through the suggestions in the article though would help you discard the usual suspects which cause the problem before calling CS to look at other causes. At least that way you would have a headstart and might be able to steer CS into trying something else or looking further into the issue. Swearing at them rarely helps though I must admit
