I have two OpenWRT routers and plan to configure them like
https://forum.openwrt.org/viewtopic.php?id=26290 to expand WiFi
coverage. I keep however running into a connectivity problem between
them that I don't understand.
I disabled firewall, dnsmasq and bridged eth0.1 and eth0.2 on Router B
('tangerine') to use all ports
https://gist.github.com/4ac1ceff859b14e14251 and connected its now
bridged WAN port to one of Router's B ('selective') LAN ports.
Everything seems to be working, even IPv6 autoconfiguration (there's
radvd on selective) but there is a very high packet loss on
connections from selective to tangerine
root@selective:~# ping -c 20 tangerine
PING tangerine (192.168.13.2): 56 data bytes
64 bytes from 192.168.13.2: seq=0 ttl=64 time=1.521 ms
--- tangerine ping statistics ---
20 packets transmitted, 1 packets received, 95% packet loss
round-trip min/avg/max = 1.521/1.521/1.521 ms
the link is basically dead, while in the opposite direction it works
just fine (I use the IP address instead of a name because tangerine
doesn't get a response from named on selective)
root@tangerine:~# ping -c 20 192.168.13.1
PING 192.168.13.1 (192.168.13.1): 56 data bytes
64 bytes from 192.168.13.1: seq=0 ttl=64 time=1.437 ms
[...]
64 bytes from 192.168.13.1: seq=19 ttl=64 time=0.977 ms
--- 192.168.13.1 ping statistics ---
20 packets transmitted, 20 packets received, 0% packet loss
round-trip min/avg/max = 0.941/1.063/1.437 ms
Interestingly, clients connected to tangerine with a cable (I haven't
tested wifi) enjoy full connectivity, while clients connected to
selective both over wifi and cable, have the same problems with
reaching tangerine reliably.
Router A ('selective') is TL-WR1043ND running ATTITUDE ADJUSTMENT
(12.09-beta, r33312);
Router B ('tangerine') is an old WRT54GL running ATTITUDE ADJUSTMENT
(Bleeding Edge, r33460) which I compiled.
What am I missing? What can be the problem? What other info should I provide?
