Internet speed on Tunnel Client LAN

Quick question please:
Recently setup a couple of Trevor's Internet Mesh Nodes and sure appreciate the work he did to present this system.  I noticed that the internet speed on the tunnel's LAN is greatly reduced from the speed offered by my home wireless network.  My 2.4G home network runs at about 50 mbps while the speed on the internet when connected to the tunnel's AP is under 5 mpbs.  Any ideas on what causes this and possible ways to correct same?
Many thanks for any input.  :)

Well not knowing your network

Well not knowing your network layout my first question would be is your internet on your mesh node being routed out another remote mesh node? Or if this is over a cellular link that would be a slow down. A traceroute might help to verify that.

I don’t think anyone has ever profiled tunnel performance speed as is not intended to be a primary path so I am not sure what our max tunnel speeds are (any sort of VPN Connection like tunnels is usually less than wire speed performance)

Traceroute info and clarification

Thank you very much for the quick response!  Please allow me to apologize for the inaccurate description of my network.  I'm a real newbie at AREDN and TCP/IP in general.  My Internet Mesh Node is an exact copy of Trevor's and is currently obtaining internet access via it's AirGateway which is connected wirelessly to my home network on 2.4g.  When I connect directly to my home wireless network on 2.4g I get about 50 mbps speeds.  When I connect to the AP of the Internet Mesh Node and perform the same speed test I get approximately 5 mbps speeds.  Here are traceroutes to performed in these two configurations:

VIA:  Macbook Pro connected wireless directly to home wireless 2.4g AP.

This is not so good, we’re seeing some packet loss from localnode to This isn’t a good sign. Since the mesh node is responding ok in the previous hop I would question the cables and switches and devices between the mesh node and, also it’s a question if this wireless client/bridge is having trouble connecting to the Access  Point due to its position or how it’s mounted in your kit. Your going to want to look at the RF link quality at this stage as well. In theory it could also be the mesh node itself is having trouble routing from its LAN to WAN port but I usually expect that to show up on hop 1.

 > 3 (  90.700 ms  82.213 ms  14.622 ms
By this point everything is so slow with such high latency and variability in the packet latency I would expect slow downs to be occurring.

Considering I haven’t built a Trevor setup that is about all I can offer on what I’m seeing but that should provide a starting point to review what is going on.

slow tunnel

I am having similar speed issues.
Running traceroute from within the node to the tunnel server internet IP yields 74ms direct and 1350ms (avg numbers) through the tunnel over the same path.
I am going to try different hardware for the client to see if it makes a difference.

Tunnel performance through AT&T

After some troubleshooting and research, I have concluded that the AT&T 5268AC modem slows down the tunnel by a factor of 10!
There may be some setting on it that I can change, but I haven't found it.
Does anyone else have AT&T service and good tunnel performance?
I can ping the non-tunnel internet IP at 70ms, But when I go through the tunnel, it's 1500ms.
Testing with other hams who have Time-warner cable modem, show no speed drop.
