Building up a mesh network with my wrt1900acs


#1

Hello guys,

I wanted to know if it is possible to set up a mesh network with my wrt1900acs. The iw list command does not indicate that the hardware is capable of 802.11s at all.


Supported interface modes:
	 * managed
	 * AP
	 * AP/VLAN
	 * monitor
Band 1:
	Capabilities: 0x106f
		RX LDPC
		HT20/HT40
		SM Power Save disabled

Supported interface modes:
	 * managed
	 * AP
	 * AP/VLAN
	 * monitor
Band 2:
	Capabilities: 0x106f
		RX LDPC
		HT20/HT40
		SM Power Save disabled

I don't want to believe that the almost flagship of Linksys can't do that.

Thx for your help.

802.11s support depends on driver.

wrt1900acs uses marvell chipset. mwlwifi (the driver) doesn't support mesh.

You can checkout the mwlwifi repo on github. The main contributor said that mesh support is considered but not a priority.

Thanks guys for your quick answer. I feared it, but I didn't want it to be true.

The latest snapshot on my wrt3200acm seems to support mesh.. but I'm yet to be able to configure it...

Wiphy phy1

        Device supports T-DLS.

        Supported interface modes:

                 * AP/VLAN
                 * monitor
                 * mesh point

These are the command I ran.

root@LEDE:~# iw phy phy1 interface add mesh0 type mp mesh_id spiderweb
root@LEDE:~# ifconfig -a | grep mesh0
mesh0     Link encap:Ethernet  HWaddr 62:38:E0:BA:DC:B8
root@LEDE:~# ifconfig mesh0 up
ifconfig: SIOCSIFFLAGS: Operation not permitted

While there may still be device/driver issues, the post below shows my working, UCI-based configuration for 802.11s mesh
