How to tell if my router has been hacked?

Question

I've noticed that my home broadband speed seems to be a bit slow in recent days. I noticed, last night, that my Wireless Router had given a DHCP lease to a public IP address with an odd formation; something like 111.10.11.110.

Should I consider these warning signs of my ZyXEL router being compromised in some way?

Answer 1

First things first, change your passwords and check your configuration settings.

That being said, I don't think it's been compromised, though a lease to a public IP address sounds funny. Perhaps you are mixing up some terms?
