RBS and RBR 750 wired backhaul

I have an RBS750 connected to a netgear switch via a wired connection 

I also have a RBR750 connected to that same switch, again via a wired connection (

 

The RBR750 is not acting as a router, just as an access point (so WAN port unused) 

 

The RBS750 is running V7.2.6.31

The RNR750 is running V7.2.6.31_5.0.24

 

 

Currently I can reach either device over the wired interfaces, and wireless devices can connect, via either AP, to the internet. 

 

However, the RBR750 shows "satellites connected: 0" 

 

Is there any reason the RBR isn't seeing the RBS as a sat here?

Re: RBS and RBR 750 wired backhaul

What is the brand and model# of this switch? 

Be sure the switch is connected behind the RBR:

While in AP mode, be sure to connect the RBR to the host router using the WAN port on the RBR. This is required for AP mode. Then Switch connected to one of the LAN ports behind the RBR.

Re: RBS and RBR 750 wired backhaul

My setup is as per the third diagram in that link - with the router also connected to the switch.

When you say: 

"

"

Maybe that is the problem then. As it stands, the RBR WAN port is disconnected 

 

 

The RBR LAN port is connected to a GS116LP switch 

The RBS LAN port is connected to the same switch 

The Router (openWRT) is also connected to that same switch 

 

The above worked fine when the RBS was not wired - and the RBR saw it as a satellite

Now that it is wired, it works at one level - things can connect to it fine....it's just that the RBR doesn't think it has any sats - so maybe it is working more as a "dumb AP" than a mesh network

Re: RBS and RBR 750 wired backhaul

go:

openwrt router---->orbi RBR wan port---->lan port out to switch------>switch------>satellites. 

when hardwired, the satellite has to be wired into the rbr's lan port and the RBR needs to be connected to the primary router via wan port.

Re: RBS and RBR 750 wired backhaul

Yes, not using the WAN port will cause problems. Set up the configuration as suggested...should work for you. 

 

Let us know how it goes. There maybe something on the switch that may need configuration since that is a managed switch. Hopefully you won't.

Re: RBS and RBR 750 wired backhaul

Thanks 

 

It turns out I don't have enough copper laid under the floor to run the router through the RBR750 WAN port as well as connect the LAN port to the switch

 

However, as a check I removed the wired connection from the RBS750 

Within a minute or so the RBR750 detected it as a satellite - and all continued to work 

 

So I guess the question becomes: 

 

Is it better to have the RBS on a wired connection, apparently working fine, but with the RBR unaware of it, OR have the RBS on a wireless only connection, and have the RBR aware of it. 

 

It feels like the advantage to the second option is nice handover between base stations 

The advantage to the first option is better connection from the RBS to the wired network 

 

So it is probably a "suck it and see"...

Wirelessly connected.

At somepoint, when and if you get time and resources, I'd run another line from the RBR to the switch that way you can then enjoy the ethernet BH. For now, leave it as wireless and see how things work for you.

Re: RBS and RBR 750 wired backhaul

Thanks, I'll do that 

I'd a bit reluctant to run the whole wired network through the RBR, given it isn't actually doing any routing - since it introduces another possible failure point for all the wired stuff in the house 

 

I'm assuming that when I had things set up on wired earlier tonight, when it was "working" but the RBR could not see the RBS, the system was operating as two standalone access points, woth none of the mesh cooperation

 

But for now the wireless option is working fine

You don't have too. Only for the one segment for the RBS to be ethernet connected, when you get to this point.

Oh, my.  This sounds like a house built on a foundation (rather than a slab) which makes it possible to crawl around under the house and install Ethernet cables.  (Dirty, claustrophobic, etc.  But doable.) 

 

Technically, there is a method to use a single Ethernet cable between the switch location and the router location to carry both the WAN and LAN connections.  It involves creating VLANs on two managed switches. An investment of about $75 and some technical work.  Paying a teenager to crawl under the floor might be simpler.

 

If the system meets expectations using the WiFi connection between router and satellite, "problem solved".

Re: RBS and RBR 750 wired backhaul

Yep, I agree with the pragmatic "if it's working on wireless, leave it"

I don't have a crawl space - well, maybe if I were a gerbil....just enough room under floorboards for some joists 🙂 

 

The setup sketched (badly) in the attached image is what I had earlier. This worked at some level, but the RBR was unaware of the RBS 

 

The current situation is the same as the above, but with the green wired link removed. This seems to be working fine.

 

From what people have suggested here, the other option would be to run the red cable into the RBR WAN port directly. But this would have a possible risk that then all traffic from the switch to the world has to pass through the RBR

 

Thanks in any event for all the pointers

Re: RBS and RBR 750 wired backhaul

Why would you think it would be a risk? 

Can be done, however for best configuration, at some point, try to get a 2nd wire ran if possible.

One could check into Power Line adapters between the RBR and RBS as well. Others have posted this as a solution too.

Re: RBS and RBR 750 wired backhaul

Only a risk in that it is one more possible failure point on the wired network - not that I expect it to fail. 

 

 

When you suggest a direct link between RBR and RBS I guess that would be as attached. That I might be able to arrange. In the morning 🙂

No. router WAN to switch (and then to OpenWRT)  router LAN to satellite.

Re: RBS and RBR 750 wired backhaul

Let us know how it goes. Just need the WAN port of the RBR connected then the RBS connected some how behind the RBR. Got another switch on hand that you could deploy? Something like NGs GS305 or 105 would work.
