Problem with configuration of single radio TP-Link CP510 with encrypted mesh

Problem with configuration of single radio TP-Link CP510 with encrypted mesh

netzcoop opened this issue 6 years ago · 9 comments

The TP-Link CP510 (having only 5G) creates a mesh over the 5G (encrypted) and we can see him with bmx6 (orin the other setup with bmx7), but he is not in the configured subnet (10.5*.*) instead he uses the ip 192.168.1.1.
So it is not possible to use the router as Gateway.

We want to use this router as a bridge for longer distances and to offer net over wdr4300 or the TP-Link CP210.

We tried with bmx6 and bmx7

Packages used:

lime-basic-no-ui hostapd-mini lime-debug -dnsmasq -wpad-mini wpad-mesh
(For the bmx7 setup: bmx7 additional: lime-proto-bmx7 bmx7 bmx7-auto-gw-mode)

Our configuration lime_defaults:
config lime system
option hostname '%M4%M5%M6'
option domain 'mesh.camp.local'
option keep_on_upgrade 'libremesh base-files-essential /etc/sysupgrade.conf'

config lime network
option primary_interface eth0
option main_ipv4_address '10.5.0.0/21'
option main_ipv6_address '2801:01e8:2::/64'
option bmx6_mtu '1500'
list protocols ieee80211s
list protocols lan
list protocols anygw
list protocols batadv:%N1
list protocols bmx6:13
list protocols olsr:14
list protocols olsr6:15
list protocols olsr2:16
list resolvers 8.8.8.8
list resolvers 4.2.2.2 # b.resolvers.Level3.net
list resolvers 141.1.1.1 # cns1.cw.net
list resolvers 2001:470:20::2 # ordns.he.net
option bmx6_over_batman false
option bmx6_pref_gw none
option bmx6_publish_ownip true
option anygw_mac "aa:aa:aa:%N1:%N2:aa"

config lime wifi
option channel_2ghz '1'
list modes 'ap'
list modes 'ieee80211s'
option ap_ssid 'CAMP'
option ap_encryption 'psk2+ccmp'
option ap_key 'PASSWORD'

Do we need a special Package config to get the Setup working with Hardware with Single Radio?

thank you for your good support!

Hi!

'bridging' is a layer-2 concept. you can do that with batman-adv, but what bmx6/7 does is routing, ie. setup routes between layer-3 subnets. Please elaborate a bit more **which** router cannot be used as a gateway into **which** network and why.

you miss all the mesh-specific wifi settings in the wifi section. maybe add something like: option htmode_5ghz 'HT40' option channel_5ghz '36' option country 'NL' option ieee80211s_mesh_id 'LiMe' option ieee80211s_mesh_fwding '0' option ieee80211s_encryption 'psk2' option ieee80211s_key 'MESHPASSWORD' Once you got that, call lime-config and see if it complains about anything. Wrongly set network stuff is often caused by lime-config falling apart due to missing settings in /etc/config/lime or /etc/config/lime-default Cheers Daniel

my bad you are right, i copied the wrong "config lime wifi" we (have multiple tried) use:
config lime wifi
option channel_5ghz '36'
option htmode_5ghz 'HT40'
list modes 'ieee80211s'
option ieee80211s_mesh_fwding '0'
option ieee80211s_mesh_id 'camp'
option ieee80211s_encryption 'psk2+ccmp'
option ieee80211s_key 'xxxxxxxxxxxxxxxxx'
option ieee80211s_bssid '15:26:F5:16:44:15'
option ieee80211s_mcast_rate_5ghz '6000'

With the CPE510 we don't use lime-smart-wifi, as i understand it should not be needed if we have a single radio (5G)
is the country option obligatory?

And for clarification for readers of this topic the setup is working for:
tl-wdr4300-v1 ubnt-unifiac-lite with the following packages "lime-basic-no-ui hostapd-mini lime-debug -dnsmasq -wpad-mini lime-smart-wifi wpad-mesh"
And the Full lime-defaults (for 2 2.4G and 5G Radios) config:

config lime system
option hostname '%M4%M5%M6'
option domain 'mesh.camp.local'
option keep_on_upgrade 'libremesh base-files-essential /etc/sysupgrade.conf'
config lime network
option primary_interface eth0

list channels_5ghz '44 128 100'

As in the other topic sayd i will fix the channels to: 1 5 9 13

the tip with lime-config is good now I can see the errors by myself (the problem is that we don't use the routers all time of the year so we are not in it so deeply ):

option channel_5ghz '36'

list modes 'ieee80211s'
option ieee80211s_mesh_fwding '0'
option ieee80211s_mesh_id 'camp'

And I added to the config:
list modes 'ap'
option ap_ssid 'CAMP'
option ap_encryption 'psk2+ccmp'
option ap_key 'PASSWORD'

no it is working! thanx a lot!
should it not be possible to configure a device just for mesh without ap? with the encrypted setting the ap must be dissabled on a single radio router it is only possible to use mesh or ap....

Answer 3 · 2018-08-07T11:12:27.000Z

i tested with the bmx7 setup and bmx6 setup...

Answer 4 · 2018-08-07T12:34:05.000Z

should it not be possible to configure a device just for mesh without ap? with the encrypted setting the ap must be dissabled on a single radio router it is only possible to use mesh or ap....

You can totally do that, however, a lot of values (like addresses) are calculated on the base of the ap_ssid, so you still need to set that even if you don't actually use the device as an AP.

Answer 5 · 2018-08-07T12:38:19.000Z

ok i understand,
thx for the info

Answer 6 · 2018-08-08T11:47:36.000Z

can you tell me what is the preferred/best way to disable the AP if not needed.

The problem (with TP-Link CP510) is that the wlan0-mesh changes from Mode: Mesh Point to Mode: Client even if the AP is disabled....

Answer 7 · 2018-08-09T00:00:00.000Z

Remove ap and ap-name from the wifi modes section in the lime config file.

Answer 8 · 2018-10-01T19:11:13.000Z

@netzcoop can we close this?

Answer 9 · 2018-10-10T11:16:48.000Z

yes it can be closed
