Megacable: a bit of a warning (somewhat technical)

[grumbalina]

Honestly, the more I think about it, the less worried I am. For someone to exploit this readily available information about your router, they'd actually have to be on your network intercepting your wireless signal. The default gateway is the same for everyone with a certain type of router, and it's not like there's some central website you can go to and access someone's specific router number to gain access. For example, I have a Telmex router and I'm sure that most people within my wifi range have Telmex routers, but I can't only access my own router with the default gateway, even though we all have same default gateway.

And the severe security glitch listed in the link you provided isn't that your router login information is listed online, it's that there's a default administrator that you can't delete or change the password for, which again, is only an issue if someone has direct access to your network. It's probably more of an issue when the router is used by multiple users.

More than likely, you have an app or a device installed that is pinging your router with various IP addresses. There are lots of stuff to be worried about online, but I think your router security concern isn't as severe as you thought, especially for individual users.
