Hi sorry if I'm using poor LAN language.

I find that plugging in a second ~~"router"~~ breaks the internet connection - is that possible or just a coincidence?

UFB -> Asus Modem/Router -> wifi x3

Asus Modem/Router -ethernet-> Safesurfer ~~"router"~~ -> wifi x 2

Asus Modem/Router -ethernet-> Xbox

Asus Modem/Router -ethernet-> PC

Asus Modem/Router -ethernet-> TV

The devices that don't get internet are mainly Apple iphones and ipads. The windows PC/Xbox/TV works 100% fine. Windows laptops on wifi are usually ok but sometimes randomly don't get internet.

The solution seems to be unplug the Safesurfer router (keep it unplugged), reboot modem, everything ok. Then after a few weeks i decide to test out the theory, plug in the Safesurfer, and within a couple of weeks the internet breaks. Exclude the safesurfer + reboot -> everything fine. (In the past if i don't exclude the safesurfer rebooting only the Asus fixes Windows wifi but does not fix apple wifi).

Any ideas?😕

What port are you plugging into the safesurfer with?

What channel wifi is the safesurfer using and what channel is the Asus router using? They should be different. I assume it gives you a separate wireless connection to connect to?

umm in think it's plugged into ethernet port 2 or 3

i cannot control the safesurfer's wifi channel - one is 2.4GHz one is 5GHz

Asus channels are set to auto for 2.4GHz x1 and 2x 5GHz

in total 5 different wifi SSIDs

You'll likely need to disable the ARP protection on your ASUS. These 'safe' routers work by ARP spoofing / Poisoning which routers often will see as malicious.

Is the second router using a static IP?

Is the DHCP disabled on the second router - using only the first router to manage addresses and avoid conflicts?

If not, is it causing double-NAT to happen?

Why do you need a second router in first place?

I will look into my Asus (RT AC3200) later. I don't think it is on static. It likes to crash when I touch it - it's fine if I don't touch it so I'm happy with it for the moment .

The second router cannot be configured so I am presuming yes to second question.

Why because the wife wants me to. Now she might change her mind.

So I take it the symptoms I'm describing is very possible caused by the safesurfer?

It's actually useless. It doesn't block anything useful.

My mate on stuff fibre is amazing he can contol everything (blocking content from kid devices) from his phone.

Unfortunately I'm with spark and I'm quite happy with it. But might have to change to stuff as kids are growing up.

Out of interest, try changing your DNS on your devices which aren't working to Google's 8.8.8.8 or Cloudflare 1.1.1.1 and see if this fixes it?

Your issues mirror that of mine which were DNS related.

Are you talking about the Safesurfer Lifeguard?

Yes that's the one. I hope I've named it correctly as a "router" 😬 !!!

thanks, but that is a bridge too far, I don't want to play with the settings of each device, if the safesurfer (which is useless, just to keep wife happy) is the problem I'll move it on.

Ok, that is not a "router". These devices hijack your router address and intercept all traffic. These devices can easily cause trouble in a network and can't be easily configured.

The best option would be to use a DNS service like OpenDNS or 1.1.1.1 for Families if you wanted to block access to specific types of content.

Reading the FAQ and the "How it works" it seems to just be a DNS filter, much like a Pi Hole. As to whats breaking your network connections cannot say from afar, but first thing I would do is try a different DNS on broken devices to see if that fixs them, ie 8.8.8.8 just as a test.

Edit, just saw the post above, that too

might i recommend going with an uncomplicated option of removing the safe surfer and just using netshield basic?

It does the same as your doing.....

The box doesn't intercept traffic from my asus does it? Only the devices connected to the box?

Thanks I'll look into those. Might ask more questions when have them.
