So I'm having real trouble getting the Google Wifi set up with the existing network in a place I've moved into. We have Fibre with Trustpower that goes from ONT into the provided modem which is a Netcomm Wireless NF18ACV. Fine if you a near the modem but the house is big so struggles to cover the place.

 

I have three Google Wifi units but I just can't even get the first one connected. The annoying thing is, it isn't even failing in the same place, sometimes it is because it will keep telling me the ethernet cord needs to be plugged in, other times I get past that and go through naming the network and setting a password, only for it to fail at "finalizing your WiFi network". Telling me that something has gone wrong and looks like they lost contact with the Wifi point.

 

So I have tried setting this up using both an iPhone and a Moto G6 android. I get further in the process with the Moto than I do using the iPhone. I've tried factory reseting the Google units, swapping out different units for the initial set up, as well as different (new) ethernet cables.

 

I had done some reading on here and Google about Bridging and tried that but honestly i'm not 100% sure I did it right and it didn't work anyway.

 

So I'm not sure if I need to bridge Trustpowers provided modum, if I have double-NAT that is stopping it or Trustpower uses VLAN tagging that won't allow it (or all of the above)

 

I am ok technicality and happy to give things a go but my knowledge is more Google-Fu and I'm just stuck now. Hoping I haven't just got some useless Google points.

 

Here is the modem information

 

 

Here is the WAN info

 

 

Happy to provide or answer anything else but would really appreciate some help to get this sorted. Thanks

Hi, I dont believe you can bridge the ethernet wan of those routers, only the vDSL port, but I could be wrong, so the only solution for now is to double nat, and to achieve that simply put the GWiFi wan in DHCP mode.

 

To fix the problem I recommend you get a small managed switch, and use this to drop the vlan, and get rid of the Netcomm from the network, this will get around double nat and provide the best solution.

 

If you need more lan ports at the ONT/GoWiFi main location then you can also consider an 8 port switch to give those extra ports.

 

If you want details on how to setup, just say

I'm not a fan of any mesh product, but of all of them Google WiFi is one of the worst.

 

It doesn't support VLAN tagging so it can't be used as your primary router with a RSP that requires VLAN tagging. I also don't believe an NF18AC will bridging like you are trying because it's not something you'd ever use a router for. Google WiFi also has a terrible bridge mode.

 

Your options are

 

a) replace Google WiFI with something newer and better that is suited to your requirements

 

b) run Google WiFi behind the NF18ACV in standard NAT mode. Because you're with an ISP already using CG-NAT this will mean you have triple NAT occuring.

 

c) buy a cheap managed switch or Mikrotik router to handle your VLAN tagging.

Ok brilliant thanks for that advice. So I didn't do something wrong with the bridging attempt apart from trying it on something that couldn't actually be bridged. lol

 

Switch seems to be the way to go next and to also to make sure I don't have a double NAT happening. Don't think I'll try for the Google behind the NF18ACV unless I really have too.

Option C can be done for under 50$ for an entry level mikrotik configured with a bridge containing one vlan10 port and one normal port

You will still have double NAT as you are with a RSP that is providing you a CG-NAT connection. You will simply avoid having triple NAT, which in itself isn't really a big deal considering you have double NAT now and hardware that will have no trouble with routing performance.

From the screenshots you have attached above, it also looks like you are on CGNAT which will be triple NAT'ing your connection.

 

If you jump on the Trustpower Website/App and chat with the Webchat team and ask them to have CGN removed from your connection they should be able to move you to a Dynamic Public IP at no cost.

Honestly, I don't know if I'm just stupid or what but I just can't get it to work. I hate giving up but getting close to just bloody selling them. Im going to give some screenshots that may give away to much information but personal I need to solve this.

 

 

 

So got the Netcomm Wireless NF18ACV from Trustpower, that learnt you can't bridge. The ONT goes into this in the WAN port. Out of the router from Ethernet 1, it goes to the new TL-SG105E into 1 and then I had going out of 2 the cable going to the Google Wifi to set it up.

 

Here is the first screen oon TP link when it is plugged into the laptop

 

 

Here is the IP Settings, set up told me to leave it as is

 

 

I set up VLAN so that port 1 coming from the router was tagged and left other ports as they were.

 

 

Now have I done something wrong? Unless the ethernet cable is plugged in from the switch, I can't log into it using the TP-Link program. Is that correct or have I missed something and why I'm having trouble in later bit? I have the IP that the switch is supposed to be on but can't get into it, I also noticed there is two IP addresses showing. One showing the IP address which I think will be the original and the "located on IP network" is the switch?

 

I ping them and can get the original but the second IP comes back with this weird information as below

 

 

So then I tried setting up the Google Wifi running from the switch, but it isn't completing set up. It was telling me it failed but it was appearing on the app. However it was dead and meant all the google products (Chromecast, minis, assistant) couldn't be reached. Had to delete it all and log them back into the old network again.

 

Just I am feeling that I'm not as computer-literate as I thought I was and its really bugging me, as my room (down other end of house) has no wifi and I need it fixed.

Typically you would EXCLUDE two switch ports, say 4 and 5 from the native vlan. Then setup port 4 as vlanid=10 TAGGED and port 5 as vlanid=10 UNTAGGED. Remove router and connect switch port 4 to ONT and port 5 to Google Wifi WAN. You could also put a static address on switch in order to connect to it once router removed and no DHCP server exists.

Ok so I'm taking out Trustpower modem and plugging straight from ONT to the switch and then from switch to the Google Wifi? The Google Wifi isn't a modem, its a router so will still work with no modem in the link?

Trustpower device is a router with an Ethernet WAN interface, Google Wifi is the same, a router with an Ethernet WAN interface.

With fibre the modem is technically the Ont, so all you need is routers.

As mentioned before using both the netcomm and Google WiFi will result in double nat, while this will work its a ill conditioned configuration.

Further, as mentioned a small managed switch can remove the vlan for you, or alternatively if you can turn off Nat on the Google WiFi and put in routes to link the two together you can circumvent double nat, but the switch solution is superior.
