MR70/MS70, no wired backhaul?
I am trying to get wired backhaul to work. Wirelesly the satellites are found. They connect and show up in the admin ui as connected wirelesly. When I plug in a network cable to the satellite the led...
I have some cables running through the wall but don't feel like putting more on the wall.
Anyhow, I connected it as per the Netgear diagram I posted earlier and the WAN port was connected to the 16port switch. It threw off my whole network :o It also started mapping all devices in my network which seems curious to me, as the MR70 was effectively mapping network device in the network at the WAN port. So there definetely seem to be a few routing tricks happening. Also, perhaps most important, backhaul never switched to wired. It stayed wireless. In a few hours I'll do my last test by actually putting the MR between the router and 16gbit switch. But after the test I just did I do not feel confident that it will work.
There are indeed some more data eputin tricks involved.
First point: You talk of "switch" or for the further test multiple "switches".
Crux is that Netgear Nighthawk Mesh are (all!) making use of Easy Mesh. Under the hood this translates to IEEE 1905.1.
Rule #1: Always tell us what kind of switches (make, models, firmware, network layout and configuration) are involved.
This means that switches configured with any kind of loop protection will see the same device dynamically (resp MAC address) not only on roaming on different edges of the LAN, respectively a loop protection can and will detect a loop - and therefore block sine ports.
Rule #2: Disable any kind loop prevention or loop protection.
Even on a LAN operating on Spanning Tree, issues can arise.
Rule #3: In a networks operating any kind of Spanning Three (RSTP preferred) configure all ports facing such mesh systems as Edge Ports.
Not sure by how far in AP mode, the MR70 needs to be in the middle of the network - certainly a good starting point for testing as already suggested
With a Mesh system based on pure Gb Ethernet, I can't see on how you can reach a better overall performance by deploying 2.5 GbE or faster MulitGig cores.
#1 and #2: network switch is a Netgear GS116v2 16 port 1gbps smart switch. Loop prevention was already disabled. Looked into that already.
#3: my router is already 2,5gbps. When I buy a 2,5gbps switch and the MR70 is between the router and switch the MR will bottleneck it at 1gbps.
Will look into IEEE 1905.1. Thanks.
#1 and #2: network switch is a Netgear GS116v2 16 port 1gbps smart switch.
GS116Ev2 in this case - the GS116v2 is an unmanaged model with no way to disable the loop prevention.
#3: my router is already 2,5gbps. When I buy a 2,5gbps switch and the MR70 is between the router and switch the MR will bottleneck it at 1gbps.
Each MR70 and MS70 will be a bottleneck if operated on Ethernet due to their 1 GbE ports.
Important details - yes, the GS116Ev2 :) And yes, the MR70 will be a bottleneck between WAN and wireless connection due to 1gbit ports. But in the suggested (necessary) installation method the MR would also be a bottleneck for wired connections. So plan is now to put the LAN side of the MR in a seperate VLAN together with the satellite. Will take some time though, Iḿ familiar with the theory but not practice and don´t want to shutdown internet for everyone in the house ;)
So you have a GS116Ev2? If so, then this is considered a Smart managed switch. Not an actual unmanaged switch. These smart or managed switches have known issues with MESH systems, especially in between the MR and MS while in AP mode. The GS switch I used yesterday is not a smart or managed switch thus saw no issues with it in between the MR and MS.
You said this configuration worked for the MR and MS: router -> main 16p switch -> WAN port - MR <- LAN port <- MS satellite.
However, you said that this configuration failed? router -> main 16p switch -> WAN port - MR <- LAN port <- 5p switch <- MS satellite.
Could it be this 5port switch in between the MR and MS causing problems here?What brand and model# is this 5 port switch?
I do have some smart managed switches I can help check this with...
Yes the 16p is a smart switch. The 5p switch is a Ubiquity Flex Mini 5p 2,5gb. https://eu.store.ui.com/eu/en/products/usw-flex-2-5g-5
So time to fire-up the UniFi Network Console application. Some Internet ressources claim the Loop Protection and/or RSTP might be enabled by default - for that switch, or for the complete scope, the UniFi Zone-Based Firewall...
Ya, this switch maybe smart/managed as well which if so, would be a cause of the problem with it in between the MR and MS which seems to be failing here.
See if you can make any adjustments to this switch.
If not, or nothing changes the issue, since the connection rate in between the MR and MS is only 1Gb, find you a native non managed switch, the the one I used, GS105 0r GS108, GS305 or GS308 will work too. There cheap these days and should be easy to find you something to use there. I'd put the ubiquity switch upstream, after the host router would be best.
