hi,
i want to link between 2 points with tp link cpe510 via mesh11sd. but cpe510 has 1 ethernet interface and it is configured as lan. there is no wan port.
how can setup this scenario?
something like this:
What is the default configuration with a new, untouched, OpenWrt reflash?
Normally you would expect either:
- Ethernet port is WAN, Wireless is LAN
- As it is a Customer Premises Equipment (CPE), you might expect Wireless is WAN and Ethernet is LAN.
Of course, the OpenWrt default is to have wireless disabled.
The answers to this are important because it will determine the settings required for mesh11sd.
It is unfortunate that in many countries, available channels on 5Ghz for outdoor use are very restricted.
There is no configuration yet. Because I am doing research for a project that has not started yet. How can I make the connection between two points most smoothly? mesh11sd seemed suitable. Do you have any recommendations other than mesh11sd?
What I really want is to embed all the settings into the devices. We are in a place where power outages are common. I want the system to work even with reset settings.
You have missed my point.
I asked what the default OpenWrt config was.
But really it does not matter because this is an 8/64 MB device with a low spec SoC and is really EOL as far as OpenWrt is concerned. It should not be used for a new project. If this is at the research stage, seriously consider something other than a CPE510 to use....
What is the range?
What is the expected traffic type?
yes I missed your point. ethernet is lan (br-lan). there is no wan interface. is there only lan interface in Network->interfaces.
My friend has no internet or telephone infrastructure in his new house. He wants to use wireless internet from his friends nearby. Since we already have a cpe510, we decided to use it. The devices are in direct line of sight of each other. There is no obstacle in between.
range: approximately 200 meters, clear view
traffic type: mostly online games and internet.
Simply configure one CPE as access point and the other as WiFi client. No need for mesh11sd on a point-to-point link. Make sure to only allow frequencies for outdoor use - this depends on your region.
You need to change the LAN subnet on the client from the default to, e.g. 192.168.2.0/24. This will give you double-NAT, but let's start with getting this to work first. We can address this later.
If you want something more future-proof, consider the CPE710 or the the KuWFi N650. They are both supported and are 16/128 devices.
I run a similar setup with 3 devices (2x N650, 1x CPE710) successfully over a distance of 1km.
200 metres might be optimistic with those devices - depends on a lot of things.
Bandwidth and latency may well be an issue for gaming - just trying to set expectations.
As @andyboeh says:
You don't even need WDS, let alone a mesh.
Mesh11sd would become useful if you have more than a single point to point and really needs omnidirectional antennas, at least for a central node.
You do need a separate access point or router for your friend's house because it will be very inefficient and give poor coverage inside the house if you try to use the onboard radio of the cpe510.

I'm not sure how the CPE510 is spec'd, but I see 100/100 for the N650 - N650 connection with sub-optimal antenna placement and 300/100 for the N650 - CPE710 connection (raw WiFi speed as reported by LuCI). With the latter I can fully utilize my 130/30 Internet uplink. Both links are roughly 1000m.
Right. I have separate APs on both locations for this very reason (ZyXEL WSM20).
I have used cpe510s before. I could use 50 mbit internet as 46 mbit from about 1000 meters. that was stock firmware. I don't know if the game was played at that time. There was no problem. Now the distance has shortened to 200 meters. I don't think it will be a big problem. There is no obstacle in search.
What I wonder is which one would be more efficient? ap - wifi client? mesh11sd?
A mesh, in general, doesn't have much advantages in a two-node setup - if at all. The only advantage that comes to my mind is if you need to support VLANs over the link. I've used batman-adv in a two-node setup for this very reason.
If you only want to provide Internet access, the AP-STA setup is much easier. You can still separate the networks by assigning a guest network on your main AP to the wireless link.
NB: There are, of course, other techniques to tunnel VLANs over the wireless link, e.g. via a GRETAP interfaces. When properly set up, this also works reliably.
Thank you very much everyone.
FYI, mesh11sd gives you by default a point to multipoint vxlan tunnel and sets up a guest network using it unless you turn it off - no vlans to worry about. You can then, if so inclined to go super clever, choose to enable a trunk mode to carry any vlans out to meshnodes in the vxlan group.
