Mwan3 interfaces always down

gfucka · May 21, 2019, 7:09am

Hi,
I have a TP-Link TL-MR3420 v1 with OpenWrt Barrier Breaker 14.07 / LuCI Trunk (0.12+svn-r10530).

I configure two wans (wan and wan2). The two wans work fine, I have internet with each of them.

I install mwan3 1.5-10 and luci-app-mwan3 1.3-5.

The wan iterfaces in MWAN live status are always Offline though it are online and working good.

This is the /etc/config/network

config interface 'loopback'
	option ifname 'lo'
	option proto 'static'
	option ipaddr '127.0.0.1'
	option netmask '255.0.0.0'

Can you help me to understand why mwan not recognize the interface status.

The MQAN Interface Systemlog show me this errors:

And if I go to diagnostic I can ping default gateway and tracking IP but Check Ip rules returns

Missing both of the required interface IP rules

and Check routing table returns

Missing required interface routing table 1

Please help me.

Thanks

Try remove gateway on lan interface

config interface 'lan'
	option gateway '192.168.2.1'

gfucka · May 21, 2019, 8:43am

I do it

config interface 'lan'
	option force_link '1'
	option type 'bridge'
	option proto 'static'
	option netmask '255.255.255.0'
	option _orig_ifname 'eth0 radio0.network1'
	option _orig_bridge 'true'
	option ipaddr '192.168.2.1'
	option ifname 'eth0.1'

but interface still offline....

leeandy · May 21, 2019, 9:08am

Does you reboot router ? Why don't you upgrade it to Openwrt 15.05 ? BB 14.07 is no longer supported.

gfucka · May 21, 2019, 9:18am

Ok yes I will try to update OpenWrt, I find on official page the 17.01.5 version for my router.
I try and then tell you.

Thanks

leeandy · May 21, 2019, 9:30am

I think 17.01 is not recommend for 4MB flash 32MB ram router, it not enough space for install mwan.
See this warning: https://openwrt.org/supported_devices/432_warning

gfucka · May 21, 2019, 9:44am

So what do you advise to do?

leeandy · May 21, 2019, 9:49am

Try with 15.05 or change another router with more ram/flash.

gfucka · May 21, 2019, 9:53am

Ok I will try 15.05 but where I can find the upgrade firmware for my router. In this page https://openwrt.org/toh/tp-link/tl-mr3420 I find just the 17.01.5...

leeandy · May 21, 2019, 9:54am

here: http://archive.openwrt.org/chaos_calmer/15.05.1/ar71xx/generic/

gfucka · May 21, 2019, 9:58am

Ok thanks.
I will flash and start all again.
Please can you indicate me a good tutorial to setup a multiwan with 2 wan.

leeandy · May 21, 2019, 10:01am

Pls see official guide here: https://openwrt.org/docs/guide-user/network/wan/multiwan/mwan3
If you have any other problems, just ask questions.

gfucka · May 21, 2019, 10:20am

Ok thanks.
I will try with 15.05 and official guide. I hope it works.
So in case I have problems with this router do you think this one (https://it.aliexpress.com/item/Cioswi-Senza-Fili-WiFi-Router-300-Mbps-802-11b-g-n-MT7620N-Chipset-Usb-wifi-ripetitore/32933932628.html) can be a good one?

leeandy · May 21, 2019, 10:41am

This router has many versions, i'm not sure it is bad or good.
See device page: https://openwrt.org/toh/zbt/wr8305rt
I suggest you use this site to find the right router for you: https://openwrt.org/toh/views/toh_available_864

gfucka · May 21, 2019, 10:45am

The one I post is 8/32. Do you think is good memory and flash or I must choose 16/32?

leeandy · May 21, 2019, 10:47am

Recommend > 8/64 for future use.

gfucka · May 21, 2019, 11:19am

Ok so I will search for a better one.

In the mwan3 official guide I read

IMPORTANT: Before doing anything with mwan3 (installing or configuring), ensure that each WAN interface is working and that the default routing table is correctly configured for each WAN connection. Test each interface with a manual ping before installing mwan3! There have been multiple reports of mwan3 problems on the forum when the problem is actually at the OS level and visible before mwan3 is even installed.

What means default routing table? And how can I check if is correctly configured?

leeandy · May 21, 2019, 11:26am

In that guide, Verify the routing table example:

root@OpenWrt:~# ip route show
default via 10.0.3.2 dev eth1  proto static  src 10.0.3.15  metric 10 
default via 10.0.4.2 dev eth2  proto static  src 10.0.4.15  metric 20

Verify outbound traffic on each WAN interface, example:
root@openwrt:~# ping -c 1 -I eth0.1 www.google.com

gfucka · May 21, 2019, 11:28am

Ok I not have yet upgrade to 15.05 because I'm not phisically near the router (i'm connect remote to it) but on actual firmware (BB) if I run ip route show nothing is show.
Can be this the problem of interface always down?
