Use SH2 for digital voice and Asus router for wired / wifi internet

JerryLee — Mon, 09 May 2022 11:04:50 GMT

Hi all,

This has been asked before I think... digital voice phone while using other router.

Got 900 full fibre on Friday. Also got ( unwanted! ) move to digital voice, and service on copper ended.

Currently use Asus AX86U as router for wired connections, AX wifi, AC wifi and backhaul to Asus repeater which is wired to 8 devices ( Playstations, Sky Q, TV etc. ) mainly on static IP.

I know I need the SH2 in the network to use the DV phone.

Trying to put it AFTER the Asus router as a device with internet access. As asus uses a 192.168.2.XXX network range I have given the SH2 a static address in that range, plugged into a LAN port on Asus and I can see the management page via the Asus... but SH2 does not get internet! Turned on and off DHCP, set custom address range into the .2.XXX range and Asus sees that, and it remains set on SH2 after saving.

So far not got phone working as no internet seen by SH2 hub.

Is the proposed above possible / likely to work?

If I use SH2 as first connection from ONT and plug router in to SH2, will Asus still provide the network connections as currently ( SH2 DHCP of? does it's IP need to be in same range as Asus or reset to .1.254? )

Not tried it yet but read I'd need to set Asus up as an access point not router ... but wouldn't that mean SH2 assigns the IP's to the devices? Can I still use the 5GHz backhaul from the repeater?

Sorry for the long post!

Thanks for any help!!

@imjolly Yes thanks, first page workaround needs some device i don't even know what it is! As well as a router.

Don't think i got to page 27 though ... I'll read on.

Via Asus router or direct to SH2 I can access the SH2 management pages..

@juiceof2limes @imjolly

Thanks for the heads up and the great info @juice!

Read most of that thread, the info on page 26 was great, easy and quick.

So got the SH2 as primary connection to the ONT and then Asus AX86U next, kept same Asus net / IP range and all worked fine.. little or no speed drop !

Many thanks all

Glad the info was helpful 🙂

I've not noticed any speed degradation or other issues with SH2/ASUS setup this way either.

One other thing, if you need/use DDNS, then you can either continue to use it on the ASUS but changing the "Method for Retrieval" to "EXTERNAL" otherwise it will pickup internal IP or you set it up on the SH2 and disable on ASUS.

I had moved it to the SH2 to do but noticed in the log that it appeared to be doing something odd and attempting to update NOIP every 15 mins approx even when IP had not changed. So I disabled it and went back to ASUS using EXTERNAL.

Struggling with move to BT DV and trying to follow the recommendation from back in 2020 from @choppyc (Message 3 of 400) https://community.bt.com/t5/Archive-Staging/Digital-Voice-with-different-Router/m-p/2105648#M1251296

We have a modern, super insulated house. Downside each room is effectively a faraday box due to foil backed insultation in walls/ ceiling. We have cat6 connections in most rooms.

We have a very successful set up.

We don't expect to get FTTH for another 24 months! We still have FTTC with copper connections to the house via telegraph poles.

This is our setup:

Openreach Master Socket -> ASUS DSL-AX82U -> all LAN connections terminate in a cisco 24-Port Unmanaged Gigabit Switch -> 7 AP connected as a mesh that provide WIFI connectivity throughout the house using backhaul connectivity via the LAN.

DSL-AX82U-8F68, IP Address: 192.168.50.1, Submask:255.255.255.0
PPPoE setup

This setup works really really well! Its been in place for about 18 months. VERY happy with it.

As some background, we were forced to go down the route of LAN backhaul connectivity as there is virtually no WIFI signal transfer from one room to another, so WIFI mesh networks that use one of the WIFI channels as the backhaul don't work! The only option was to put a WIFI access point in each room and use the wired (LAN) backhaul to the router. It works really really well.

BT have forced us over the last little while to switch to Digital Voice. We lost our dial-tone two days ago. We want to keep our current telephone and BT landline number.

It seems the only way to maintain our landline with BT digital voice is to have the BT SH2 connected as the router.

I've seen so many different alternatives of how we use the existing set up.

The one complication is I really don't want to have the additional expense of having the alarm company sending an engineer back to the house to re-program the: Virtual Server / Port Fording setting and the DDNS that link the burglar and fire alarm.

I think the setup is

1) Openreach Master Socket -> BT SH2 ->
connect phone

Disconnect from BTSH2: WIFI and DHCP server. (login to BT SH2 192.168.1.254 go to Advance setting and turn off DHCP and wireless)

2) Openreach Master Socket -> BT SH2 -> ASUS DSL-AX82U

This is the part of the setup I am not sure about...

Logic suggest having disable the DHCP and WIFI in BTSH2 I plug the a LAN cable into ASUS WAN and the other end into BT SH2 LAN port 1 .... and that I need to set up on BT SH2 some sort of static link? This is the bit I am fuzzy about and would appreciate some help...

If you wish to keep using the Asus as a router then you need to configure the ASUS and BT hub as 2 discrete sub networks. Luckily you appear to be using 192.168.50.xxx subnet for the ASUS. Give the ASUS WAN port a static IP address of 192.168.1.10 and gateway 192.168.1.254 and connect to a Hub LAN port.

Turn off WiFi and DHCP on the Hub.

I'll give that a try tonight.

ASUS must have experienced this as out of the box as it came defined not at the normal default of 192.168.1.1 but as 192.168.50.1!

I'll go dig out how I give the ASUS WAN a static IP of 192.168.1.10 and gateway 192.168.1.254

I assume in the BT SH2 all I need to do is deactivate WIFI and DHCP - I assume I don't need to do anything else.

@licquorice - many thanks, I will get back to you

Yep, that should do it.

Re: Use SH2 for digital voice and Asus router for wired / wifi internet

decimus_burton — Fri, 26 Jan 2024 19:53:00 GMT

Disabled the DHCP and WIFI in BT SH2 so that ASUS is in control

Connected to cable to OpenReach Master Socket and BT SH2.

Connected Phone to the phone connector... left it for a few mins... Checked phone. Dial tone. Yippee!

Plugged LAN cable from WAN on ASUS DSL-AX82U to Port 1 on BT SH2

The WAN on the ASUS DSL-AX82U was previously set to PPPoE - I swapped it to Static IP (picture attached)
static IP: 192.168.1.10
subnet mask: 255.255.255.0
gateway: 192.168.1.254

Having made the connection I never got an internet connection -

Have been force to remove the BT SH2 and revert to the ASUS at the front end back to PPPoE

I'm guessing I've got the WAN setup wrong?

WAN port settings on ASUS DSL-AX82U

Any suggestions?

Change DNS setting to Yes

What are the other options for wan type?

Re: Use SH2 for digital voice and Asus router for wired / wifi internet

decimus_burton — Fri, 26 Jan 2024 20:32:15 GMT

Connect to DNS Server automatically - Yes is not available! with the Static IP

Drop down option suggest varius DNS server- maybe Google 8.8.8.8 or 8.8.4.4?

Re: Use SH2 for digital voice and Asus router for wired / wifi internet

decimus_burton — Fri, 26 Jan 2024 20:41:36 GMT

WAN Type - DSL is only option

the next drop down offers two options
ADSL WAN (ATM)
VDSL WAN (PTM)

Re: Use SH2 for digital voice and Asus router for wired / wifi internet

licquorice — Fri, 26 Jan 2024 20:33:33 GMT

Yes, try Google servers

Re: Use SH2 for digital voice and Asus router for wired / wifi internet

licquorice — Fri, 26 Jan 2024 20:36:30 GMT

You can disable 802 1q, that is handled by the hub

Re: Use SH2 for digital voice and Asus router for wired / wifi internet

licquorice — Fri, 26 Jan 2024 20:48:56 GMT

Is there a fundamental setting somewhere to change the input from DSL port to wan port?

Re: Use SH2 for digital voice and Asus router for wired / wifi internet

decimus_burton — Fri, 26 Jan 2024 22:10:35 GMT

Checking into that - will try in the morning to see if by changing Dual Wan I can either change WAN or set a LAN port to a WAN?

Re: Use SH2 for digital voice and Asus router for wired / wifi internet

licquorice — Sat, 27 Jan 2024 09:29:58 GMT

I'm pretty sure there must be a way to change the WAN type from DSL to Static IP so that the device expects internet connection via the WAN port rather than the DSL port.

Hopefully our resident Asus guru @TimCurtis will be along to help

A big thank you to @licquorice for asking the right questions and helping me to SOLV the issues of how to fix our current network so we could keep our existing mesh network that uses wired backhaul (the joys of having a super insulated modern house) AND retain our BT landline

Here is a recap

1) ORIGINAL SET-UP
OpenReach Master Socket -> ASUS DSL-AX82U
(This setup used PPPoE) worked brilliantly Attached to the this router were 7 AP acting a wireless hubs though out the house.

New set-up where we needed to maintain our landline and use BT digital voice.

OpenReach Master Socket -> BT SH2 -> ASUS DSL-AX82U

Within SH2 I went into the advance section of the BT SH2 hub manager via 192.168.1.254 and turned off DHCP and Wireless. You'll need the password details on the back of the hub.

Out of the box the ASUS ASUS DSL-AX82U IP address range is setup as 192.168.50.1 to 192.168.50.254 so this was blessing in that we did not need to make any changes here.

2) NEW SET-UP to maintain using our BT Landline
OpenReach Master Socket -> BT SH2 -> ASUS DSL-AX82U
An ethernet cable is run from the blue WAN port on the ASUS DSL-AX82U to port 1 on the BT SH 2

The tricky bit was making the change to a WAN on the ASUS DSL-AX82U

It failed the first few times, this is where questioning by @licquorice was so helpful and I was able to research the issue

Under WAN the out of the box setting for the ASUS DSL-AX82U is the WAN Type is set a DSL , and on this page this cannot be changed.

WAN Type needs to be changed from DSL to WAN. To do this one has to go to another ASUS WAN tab: Dual WAN
Enable Dual WAN: OFF
Primary WAN: change from DSL to WAN (the other option was USB)
Then Apply. <- it took about 60 seconds for this to apply

Once this is done all that remains is to edit the Internet Connection for the WAN

WAN type: WAN (previously set to DSL)
WAN Connection Type: Static IP
Enable WAN: Yes
Enable NAT: Yes
Enable UPnP: Yes

Enable 802.1Q: No <- handled by BTSH2

IP Address: 192.168.1.10
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.254 <- BT SH2 gateway

There was one more ASUS setting and we used the drop down to pick two DNS servers, We picked Google.

That's it. All working. Thank you @licquorice for your help
