We were never aware of anything, until I logged in onto our router. It referred to a different IP address and I was not aware to change that. Eeven a reset did not work. It didn't show any hacker's IP address or whatsoever. The IP address was something from a Brazilian site. We bought a new router. Fokke Is that as far as it went? Just vandalism on the router? Or did they get into your computers? I feel vaguely safe with two stages of passwords; first for access through router to my ISP, second for access to the gubbins of the router itself. Ed |

They have help. https://www.shodan.io/ https://en.wikipedia.org/wiki/Shodan_(website) You can use Shodan yourself if you want. ******* Or use GRC port scanner or something. https://www.grc.com/x/ne.dll?bh0bkyd2 In some cases, a better setting for a router, is to port forward an external port to an internal (non-existent!) IP address. As no response comes back to the Internet and it maintains your "stealth" rating. Closing a port gives a closed status, which tells you "someone is home". If scanners like that scan the ports too quickly, it triggers the "anti-port-scan" behavior of your router, and this invalidates the GRC test results. I'm sure over the years, GRC has had an opportunity to amend their test procedure, so the router "doesn't notice". I haven't use that thing in years, so I can't tell you today how good of a job it is doing. But if you could see yourself in Shodan, that would generally be a bad thing. That's how they find "open" home web security cameras for example. One of our schools, a security camera was available online to anyone from the outside. Shodan helps find that stuff, but only a white-hat will take action to inform authorities who need to know. Paul |

I do not know if resetting restores the original firmware, ignoring any firmware updates that I installed. The firmware is sort of like an Operating System. Resetting doesn't restore a previous firmware. It only resets some/most of the settings, usually enough to get you back to a known state. Most routers I've looked into can save the current firmware by logging into it, going into Advanced, clicking ok to the warning of perilous territory, and selecting Tools. That saves the settings, not the firmware itself. I haven't seen a router that provides a function to save the current firmware. There's no need to since you can download a fresh copy or use a copy that you've saved on disk. You can then restore from that saved file; or reset to factory default from a file held in the router itself. And after that you can hunt down subsequent updates on the manufacturer's website. Agreed, but saving or restoring settings will leave you with the same firmware that you had before you did those things. If you want to change the firmware, you have to download the new firmware from somewhere, then upload it to the router and boot into it. -- Char Jackson |
