Need to extend a SonicWall TZ 400W ( wireless)  with  Sonic Wave  or Sonic Point ?

I manage a small legal office and have a SonicWall TZ 400 wireless that covers the current building ( 15 people on the LANand only one using wifi)
The owner of the company will be expanding into a separate building across a 30 foot Breezeway next door.
I have tested the current TZ 400 Signal and it "peters out" just outside the current office facing the new office space.
 the new office space will only have two people in it)

I cannot move the existing TZ 400 closer to the new building. ( I cannot use the AC wiring to extend the wifi)

QUESTION:  SonicWall just came out with a new "mesh" Sonic "WAVE" that are around $850 each . And it requires yearly fees but support is probably great and an integrated package may make sense.  But I don't even really know if the "Wave" is the right product.  Will a SonicWall Point that not on a ethernet lan act like a mesh ?

But it  seems like a pricey solution  and I might really need two of them ( $1700)
One to boost the TZ 400w inside the edge of the existing office and one to pick up the signal in the new building.
I would like to have a ethernet port from the  device in the new building and would also like to lower the cost (above)
Does anyone suggest the SonicPoint or Ubiquity or Meraki or even Google  Wifi mesh to accomplish this ?

If the buildings are linked with a 'Breezeway' there must be cable ducting running across? I would be looking at running something physical to hook up to an Access Point (AP) on the other side. With a mesh setup you are still going to have to have multiple devices to stretch the network that far. Overall speed of the wireless will also decrease if your only uplink is on Building 1 (as each user will need to be connected to an AP, which will then have to send packets through the mesh to the uplink AP).

Failing the availability of extending the current network directly, look at the costs of getting a new uplink in Building 2 and connect them via VPN, route internal traffic over VPN and external direct to internet (once again to reduce bandwidth).


Thank you for that comment, that is a keen observation and you have two good alternatives in many cases,  Unfortunately I did not mention that we are unable to do any building wall penetrations ( the landlord is extremely difficult to deal with ) and the VPN would require our internet vendor to face the same penetration issue.,

Are both buildings owned by the same landlord? Were they both built at the same time? If so there is probably shared ducting that already exists you should be able to piggy back off.

Surely your Landlord must be providing allowing you to have a leased line, at the very least he should be providing connectivity to a secured comms room? Any building these days, for office use, should come pre-wired for power and network connectivity back to a patch panel/comms room.

Working within your current constraints, do you actually have locations you can power the additional AP's from to even form a mesh?


While I appreciate your comments and valuable insights, I need to move this question into the RADIO-MESH direction. ( I have over 20 SonicWalls with site to site VPNs at other businesses I have installed and maintain on a regular basis , I know  my constraints on this one and need advice on current RADIO MESH product options with SonicWall as a base firewall.

Nobody is questioning whether you know your constraints, but sharing them can also help in case there is a feasible alternative you haven't thought about.

As far as mesh products go, you'd get a much better value going the Ubiquiti route than Sonicwall. Sonicwall wireless products are blatantly overpriced for what they are. Ruckus products aren't cheap by any means, but can also do fairly well in areas with lots of walls blocking signals. I've heard good things about Xirrus, but I've personally never used them. In the scenarios I'm naming, it doesn't matter what your firewall is, however you're obviously not using the firewall to manage them.

As far as the UniFi mesh products go, here's an article from Ubiquiti themselves: https://blog.ubnt.com/2017/01/29/moving-beyond-conventional-wireless-network-unifi-mesh/
