1430263 2016-12-28 19:38:00 It sounds like DNS may be your largest problem.

Most routers are also a DHCP server.

This means your new equipment, and your old equipment, probably both have DHCP services. This is bad (unless you've done some advanced DHCP configuring on both).

A single DHCP server does a couple of things, and generally make your life easier. However two competing DHCP servers will likely cause general weirdness on your network.

However you can tell all device to ignore DHCP, and manually set your own IP addresses and DNS settings.

For example Google has a pair of public DNS servers at IP addresses: 8.8.8.8 and 8.8.4.4 (for normal IPv4 service)

You can manually tell any device to use these servers, instead of your ISP's.

Here's a web page that describes it for Windows 10.

1430264 2016-12-28 19:49:00 kingdragonfly my router has DNS servers set which I want to use. My new ISP supplied modem/router has DNS servers hard-coded and I can't change them. When I connect to my router which is connected to the modem/router, all my connections use the DNS settings of the modem. I'm trying to bypass the modem settings and use those of the router. I've had this work in the past when I was in NZ, but I didn't need to change anything to get it to work, it just did when I plugged it all in. I'm hoping to replicate the result here, but don't know what settings to change in the new modem or my router.

Cheers,
Mike.

1430265 2016-12-28 21:51:00 When I connect to my router which is connected to the modem/router,
You have an ethernet router?
You are connecting the WAN port to a LAN port on the modem?

1430266 2016-12-28 23:23:00 I think you're missing some knowledge about DHCP and what it does.

It's what makes network settings automatic. It's also the reason why more than one DHCP service can cause problems, if not correctly set up.

Here's some generic information about how DHCP works, and why it's so important.

1430267 2016-12-28 23:45:00 You have an ethernet router?
You are connecting the WAN port to a LAN port on the modem?I've tried WAN to WAN, WAN to LAN, LAN to WAN, and LAN to LAN. Sometimes I get internet, sometimes I don't, sometimes I lose access to the other device altogether. None of these have allowed me to access the internet through the DNS servers I've specified through the router.

whatismyipaddress.com I'll take a look at that. Are you recommending I disable DHCP on both the modem/router and on the router? Or just the modem (the one I want to avoid the settings from)?

1430268 2016-12-29 00:02:00 You want to leave DHCP on on both, connect the WAN port on your router to a LAN port on the modem, set your router to get WAN IP automatically (from the DHCP on the modem) and then set your LAN-side router settings as you like and plug all your client's into your router.
As long as you don't need incoming port forwarding this should be the easiest way to get what you want.

1430269 2016-12-29 00:03:00 You can't modify your current modem/router, because you don't have the password, correct?

For simplicity, at one PC
1) Figure out your current IP address
2) temporarily disabling DHCP
3) assign the same IP address temporarily
4) experiment with DNS IP address changes, such as using 8.8.8.8 (Google's public one)

If it works, great. if it doesn't, switch back to DHCP.

1430271 2016-12-29 00:04:00 Got it working thanks to kingdragonfly and fred_fish, thank you. Connected WAN (on router) to LAN (on modem), left DHCP enabled on both, but set different pools on each 192.168.x.x on modem, 10.1.x.x on router. Suddenly my router told me it was connected and DNS is working correctly!

Thanks heaps both (and all)

Cheers,
Mike.
