Extend Wifi using two tg799vac gateways

Answered

Hi,

 

I am wondering if / how I can extend my home wifi coverage using two TG799vac gateways and some powerline adapters (as per the diagram below).

Is it just a matter of plugging the second gateway to the powerline extender using the WAN port? Is there any config I need to do on either of the gateways?

 

Thanks

Re: Extend Wifi using two tg799vac gateways

I have now tested this out using 2 TG797's successfully so it should work with 2 799's

 

  • Modem 1 is just setup as normal and is the main modem (I.e the one plugged into the phone socket)
  • Run Ethernet cable from LAN on modem 1 to WAN on modem 2. Using powerline adapters as well should work
  • Connect to modem 2 via ethernet cable or wirelessly. ( I did all this wirelessly on my phone). If doing it wirelessly, temporarily disable wifi on main router (button on top next to lights on a TG799, ECO button on a 797)
  • First go to modem config > WiFi
  • Adjust Wifi Network Names and Keys to Match modem 1's
  • Next go to to modem config > Advanced > Local Network
  • Firstly I adjusted Local Device IP address to 192.168.0.1 (This is useful later when needing to differentiate the 2)
  • Uncheck DHCP then save and reboot
  • Afterwards set your ethernet/wireless adapter to static with:
    • IP: 192.168.0.10
    • Subnet Mask: 255.255.255.0
    • Router/Gateway IP: 192.168.0.1
    • DNS: 192.168.0.1
  • Reconnect to modem 2
  • Go back to modem config > Advanced > Local Network
  • Press Bridged Mode and turn that on, then reboot router
  • Afterwards you can reconfigure your Adapter back to Use DHCP/Configure Automatically

From there you can turn the wifi back on on modem 1. Just to note the internet light will appear red on modem 2 but provided your WAN light is solid green everything should work. If you ever need to reconnect to modem 2 to get to its settings, disable wifi on modem 1 and disconnect cable in WAN slotm and then connect using the static details above and you should be able to access it. You may also be able to set modem 2's IP, disable DHCP, and enable bridged mode all in one go but I know that my method will work. You may from time to time see a wifi dropout on your devices if you are moving around the house at it swaps which modem it connects to but it seems to work quite well

 

Went from getting 20mbps (won out at my new address) at the back of my house where the phone socket is and 2.5mbps at the front of the house, to getting 15-20 mpbs across the whole house wirelessly, and saved forking out for a seperate router

Re: Extend Wifi using two tg799vac gateways

I'm not sure that the firmware in the TG799vac will allow that to work. I believe that the Pure AP functionality has been disabled.

 

You could do that kind of setup using a third party router in place of the 2nd TG.

 

@Yastiandrie, you've posted on this topic before I believe?

Never be afraid to back yourself when trying new things, just always make sure you have 3 escape routes if things go wrong.

I currently have an old router doing this at the moment but it only support 802.11n and I wanted to extend ac.

 

Thanks anyhow

Re: Extend Wifi using two tg799vac gateways

I think i posted about setting it up wirelessly, hard connection may be different. I'm still pretty skeptical of it working due to firmware limitations. Try plugging the ethernet into the LAN, disabling DHCP and  changing the wifi name and passwords to match the main modem

Re: Extend Wifi using two tg799vac gateways

Interesting.

 

I don't know how you "Uncheck DHCP" using the GUI that was supplied with the TG797n V3.

 

It can be done with the Turquoise (15.3) GUI which comes with the TG799vac but not with the GUI that comes with the 797n V3.

My software release is 10.3.v.9  (variant BN, Boot Loader Version 1.1.4).

 

Has your firware been upgraded so that it uses the new GUI?

Re: Extend Wifi using two tg799vac gateways

Yes both had their firmware updated automatically. If the modem is plugged in and connected to the internet it should update up to 15 over the course of a few days. Barring that I'll have to check the old gui out tomorrow to see if there are equivalent settings and where they are

Re: Extend Wifi using two tg799vac gateways

Just had a look at my old emulator for version 10 and if you do not want to try and get the version 15 GUI on it, i'm pretty certain you do this:

 

First adjust the wifi to match your other modem by:

  • Going to Home Network on the Left
  • Clicking on WLAN
  • Then either clicking on Configure on the top right side or "Configure the main WLAN" in the "Pick a Task section"

 

Then to bridge the modem:

 

  • click on Technicolor Gateway
  • Click on Setup my Gateway in the "Pick a task section"
  • You'll get to a service selection area. I'm reasonably certain there should be a bridge mode there. If not post what options there are there
  • Go through the rest of the steps

This should also disabled DHCP at the same time (In theory). The downside to the own firmware is that there does not appear to be a way to change the routers IP Address unless you can during the "setup my gateway" area, so if you want to make adjustments to the modem after bridging:

 

  • Unplug the ethernet cable between the two modems, also disable the wifi on modem 1 if you want to connect to modem 2 wirelessly
  • Set you wireless or ethernet adapater to static with:
    • IP: 10.0.0.50
    • Subnet Mask: 255.255.255.0
    • Gateway: 10.0.0.138
  • Connect wirelessly or wired to modem 2
  • Make adjustments or run through the "Setup my gateway" as required

Alternatively you can just factory reset modem 2

Re: Extend Wifi using two tg799vac gateways

Thanks for your help.

 

I seemlessly swapped my TG797 for my Gateway TG799 and waited for Telstra to update the software.

 

They did this within the hour and I was able to turn off the DHCP Server and assign a new IP Address from the "Local Network" Tile.

 

I can now use the TG797s as a Wireless Access Point

Re: Extend Wifi using two tg799vac gateways

Afterwards set your ethernet/wireless adapter to static with:

  • IP: 192.168.0.10
  • Subnet Mask: 255.255.255.0
  • Router/Gateway IP: 192.168.0.1
  • DNS: 192.168.0.1

Which modem is this step for the main, or the 2nd bridge modem? Also how do i do it? after i changed the local IP and turned off DHCP i was no longer able to connect to the bridge modem via entering 10.0.0.138 or 192.168.0.10 into the url.

Re: Extend Wifi using two tg799vac gateways

Thats to gain access to the bridged modem.

 

You have to make sure you are connected directly to it

Re: Extend Wifi using two tg799vac gateways

Do the two gateways need to be permanently connected once set up.  I have two Sagemcom F@ST 5355 gateways (one branded ADSL the other VDSL) but both work on the NBN.  Can I do the same?  Currently I switch between the two depending on what and where I'm using in the apartment.  The start up time switching on and off these things can be quite long.

 

The WiFi from the Sagemcom F@ST 5355 gateways is extremely weak.  They only have acceptable strength for about 1 and half rooms distance.  Not much better than the Thomson TG782T that they replaced. 

 

Note running an either net cable from one side of the apartment is not an option.  Connecting via the power points is not an option (the power is on two different circuits from the power box).  An extender is not an option (no where to put in the middle of the apartment).

 

I would be grateful for your help.

 

Thank you

Extending using 2 x TG797's successfully. Thank you Yastiandrie...

NOTE setting ethernet to static in order to connect to modem 2 further instuructions posted in response to jack37.

I also found manually changing my channel number to a less congested frequency beneficial.
