Issues - Twin Soho Surfs - One as router, one as AP

Good afternoon,

I’m having some issues with my new configuration. I’ve had a Soho Surf Mk3 for years and love its stability and functionality. I purchased a second one to use solely as a wireless access point/network extender in my home to ensure good signal and speed. I’ve done as much as I can figure to do, and although I’m sure the answer is simple, I’m stuck. Here’s what I’ve done:

  1. Direct wired connection from LAN port on Soho Surf router downstairs to LAN port on Soho Surf access point upstairs.

  2. Assigned upstairs access point IP address - downstairs router is

  3. Disabled DHCP on upstairs access point.

  4. Mirrored Wifi AP settings on both devices (SSID, security, etc).

  5. Verified and selected separate wireless channels for each.

  6. Mirrored port forwarding from downstairs router to upstairs access point.

  7. ATTEMPTED to create a WAN on upstairs access point with Static IP of xxx.11, default gateway set to downstairs router IP, DNS Didn’t seem to connect. This was my basic idea of how to get that access point work for internet access. Also not sure if IP passthrough needs to be selected but I’m hesitant to as I’ve “lost” other devices on networks with that feature sometimes.

Any assistance you all can provide would be much appreciated. I’m savvy enough to do most of this but nowhere near the abilities of most of you.



Hi Dan - welcome to the forum!

The SOHO acting purely as an access point is a little overkill and since its technically a router with an access point built in, its going to require a little bit more config.

The easiest way to set this up, is to do a wired connection from the LAN of the SOHO downstairs (lets call this one primary) to the WAN of the one upstairs (Secondary). Then change the default network subnet to something else (ie ) Then configure the SSID on the secondary and you’ll have a WIFI bubble upstairs to connect to.

The only issue with that is the Primary will see all traffic from clients connected to the secondary as coming from a single IP (the WAN IP address of the secondary) which is fine if you don’t need any advanced outbound policies to control traffic flow or any port forwarding / firewall configs to those devices (connected to the secondary soho).

However, if you do want to have visibility of the individual client / device IP addresses hanging off the Secondary soho and what they are doing bandwidth wise individually on the primary soho, then you need to do the following:

  1. Reserve an IP address on the primary for the WAN of the secondary (so the secondary’s WAN IP doesn’t change) or set a static IP there (ie
  2. add a static route to the primary for and point it to the static (or dhcp reserved) IP assigned to the secondarys WAN ie
  3. On the secondary SOHO change the WAN routing mode from NAT to IP Forwarding

Hi Martin,

Thanks so much for the welcome and especially for your time in responding. I’ve attempted to do as you suggested, but I’m coming up empty. The one thing I cannot seem to figure is how to change the default network subnet of the secondary to 192.168.51.x. The only place I can seem to do that is in DHCP which I have disable since I don’t want the upstairs (secondary) assigning IP’s. I’d prefer the downstairs (primary) assign all IP’s and policy and the upstairs merely function as a mirrored SSID access point. Maybe I am wrong here?

I did do a MAC ID DHCP reservation on the primary for the WAN MAC of the secondary:

Sorry, had to split into two posts:

I’ve configured the WAN of the secondary (upstairs) as you see here:

I cannot seem to add the static route you suggest. In any event, with these settings the upstairs (secondary) will not show an active WAN and is not accessible until I relocate my ethernet cable to a LAN port (which I do in order to access the device for configuration).

I’m sorry to ask for more of your expertise, but this has me confounded.

Thanks again,


Got to the LAN settings on the secondary (same as you show above but on the other SOHO) and change everywhere that says 192.168.50 to 192.168.51 then click save and apply. From that point onward you will have to access the secondary SOHO on its new IP address


Yes wrong. The SOHO is a router, the WIFI is on the LAN and we want to connect it to the downstairs primary SOHO using its WAN so you need the upstairs secondary router to have a different subnet range and for it to allocate that to the connected devices. Thats why we set the LAN IP to and the DHCP range to

On the downstairs primary SOHO navigate to Network > LAN | Network Settings and fill in the Static Route settings like this:

Then Click Save an Apply.

Actually. I guess although what I’m saying is ‘right and proper’ its not the simplest way to do this.
If you really just want to use the SOHO as you would a cheap Access Point then you could on the secondary SOHO:

  1. Set the LAN IP to
  2. turn off DHCP server
  3. Create a SSID that is the same as the one downstairs (same name, same password)
  4. Connect the LAN of the SOHO downstairs to the LAN of the SOHO upstairs.

Then the one downstairs would be the primary gateway / DHCP server and the SOHO upstairs just acts as an AP.

Just seems a shame since you lose out on all the good stuff the upstairs SOHO could do - but then maybe you really don’t need that… and if you don’t, then sell the SOHO on ebay and get a Pepwave AP Pro for upstairs :wink:



Thank you so much once again for your time. I’m attempting to configure this second unit for maximum functionality. Tomorrow I’m going to factory reset it to ensure that I haven’t made an error - start clean and see what happens. Just to be sure…was my WAN configuration for the secondary (upstairs) correct? I imagine that it will still be IP forwarding even though we’re going to allow the secondary to use DHCP on a different subnet. In the WAN setting for the upstairs, under IP, I imagine that’s the same as the LAN IP of that unit, i.e. (as you suggested). The gateway would have to be (the downstairs router).

Also, I was hoping you could confirm the setting you suggested on the Static Route to be installed on the downstairs (primary)…Destination network and Gateway. Also, just to confirm, I’ll need to change the DHCP reservation on the downstairs router to match the LAN MAC of the upstairs router as well as alter the reservation for the new LAN IP of

Thanks again for your time…hoping to nail this down tomorrow and see that green WAN status on the second router. I truly appreciate the help!

Yes still IP forwarding.

No WAN IP of upstairs unit has to be in the LAN subnet of downstairs unit. I would suggest you set the WAN IP to (Assuming downstairs LAN IP is

No. Either set the WAN IP of the upstairs SOHO manually to or set it to DHCP then when it connects go to the downstairs SOHO and reserve the DHCP IP it has been assigned. Remember to update the static route on the downstairs SOHO to forward all traffic for to the upstairs SOHO WAN IP (ie
