Bpi and gateway with wire

First, I have test with a bridge without ap, after I have a bridge with ap0 I have the same problem. I can make a test without bridge…

My /etc/network/interfaces for the bridge :

auto br0
iface br0 inet static
#auto wan
#auto lan3
#iface lan3 inet static
#iface wan inet static
  address 192.168.2.1
  netmask 255.255.255.0
  bridge_ports lan1 lan2 lan3 lan0 ap0
#  bridge_ports lan0 ap0 wan lan2 lan3
  bridge_fd 5
  bridge_stp no
  pre-up /home/root/wifi/wifi.sh
  up /etc/init.d/firewall start

And this is the end of your wifi.sh

if [[ $? != "0" ]]
then
	echo "Error, device no available, ap0"
else
	echo "Done, all good, ready to lauch hostapd"
	sleep 2
        hostapd -dd /etc/hostapd/hostapd.conf &
	    sleep 20
	    #ip addr add 192.168.3.1/24 dev ap0
	    #sleep 20
 	    #systemctl restart  isc-dhcp-server
        #sleep 20
        #hostapd -dd /etc/hostapd/hostapd.conf
fi

When I see this file, I remenber I have do test without bridge…

The problem is only between my computer and the bridge of the bpi-r2… With a other computer : no problem.

Now, I test this network :

Internet <=>Modem<=> BPPI-R2 <=> Switch <=> 2 computer (my computer and a other)

For this test, I don’t use the wifi. If I ping the other computer with my computer :

--- 192.168.2.100 ping statistics ---
158 packets transmitted, 158 received, 0% packet loss, time 160779ms
rtt min/avg/max/mdev = 0.163/0.213/0.509/0.067 ms

If I ping the bpi-R2 with my computer :

rtt min/avg/max/mdev = 0.349/0.466/0.559/0.054 ms

If I ping the bpi-r2 with the other computer :

rtt min/avg/max/mdev = 0.269/0.334/0.490/0.038 ms

If I ping the modem with my computer :

rtt min/avg/max/mdev = 0.540/0.894/1.055/0.078 ms

If I use the wire with my computer, the network is not good. If I use the bpi-r2’s WiFi the network is good.

please test without bridge…

why a modem between r2 and your Computers?

10

Oups… A switch ( D-LINK DGS-108 ).

11

you have connected only 1 port of bpi’s lan-ports to the switch? have you tested with another port? and without the switch?

12

I have tested without the switch and the same lan-port of the bpi-r2 with the same wire was not good with my computer and good with a other computer.

Since my PC had no problem communicating with ssh with the wan port of bpi-r2 via a swith, I tried to put the swith between my PC and the lan port.

13

Have you tried without bridge and different port?

Without bridge and lan3

Without bridge, without wire (wire in lan3 and 192.198.2.1 in lan2 : a error), via the wifi (wifi in 192.168.3.XXX)

I think that’s it’s good with this config lan0 for internet ans the other for the bridge :

root@bpi-r2:~# grep -v \# /etc/network/interfaces
source-directory /etc/network/interfaces.d
auto eth1
iface eth1 inet manual
  pre-up ip link set $IFACE up
  post-down ip link set $IFACE down

auto eth0
iface eth0 inet manual
  pre-up ip link set $IFACE up
  post-down ip link set $IFACE down

auto lan0
allow-hotplug lan0	
allow-hotplug wan
  iface lan0 inet dhcp
  pre-up ip link set $IFACE address 32:D1:55:7D:03:39 up
  up /etc/init.d/firewall start

auto br0
iface br0 inet static
  address 192.168.2.1
  netmask 255.255.255.0
  bridge_ports wan lan1 lan2 lan3
  up /etc/init.d/firewall start

Why ???

16

I don’t know if you can bridge wan to lan…but at least this line should be dropped from your config

allow-hotplug wan
17

I have try the port wan and now, I try the port lan2. The netwotk work with all.

Now, I try with ap0 in the bridge… Why not. I think that’s it’s good. I did not understand why it should not work.

You have see a error :

allow-hotplug wan

I will try without this error.

18

With or without the wifi in the bridge, it works better when the network does not go through the bpi-r2

19

do you still have Packetdrops?

can you test with latest 4.19 (main/gmac-tree)?

have you take a look on cpu-load, memory consumption and ethernet-interrupts (cat /proc/interrupts) while doing your speedtest?

20

I have less Packetdrops. But I have.

rtt min/avg/max/mdev = 23.661/24.219/26.133/0.346 ms

I can test your kernel, but where is it ? I don’t have many time before the 6/1/19…

I don’t do test with speedtest. I go to internet and when the bpi-r2 is between my computer and internet, I have to many problem, it’s slow.

21

it is slow because of packet-drops…every dropped packet have to requested and sent again

source:

compiled Package:

backup your old uImage before overwriting. you have to change kernel-var in uEnv.txt if using another name than “uImage” for kernel

but something is strange in your system/with your r2

made test from my client over r2 (forwarding+nat/pat) to internet

have you looked on soldering-points of ethernet-ports? there were some bad ones on sata of some people here…maybe your ethernet-ports are affected with same issue

22

The welds seem normal, How did you see the welding problems? My BPI-R2 is in a box : https://e.banana-pi.fr/2165-thickbox_default/boitier-acrylique-pour-le-routeur-banana-pi-bpi-r2.jpg

Why backup my kernel ? If it’s don’t run I make a new sd-card. With a new config, first only for forwarding+nat/pat to internet. Start from nothing… And try now…

Now, I run with the new kernel…

The bpi-r2 is in the network (wan with lan0) and I can not communicate with the bridge.

No time now…

23

Error… I can’t remove this.

24

You have a usb2serial-cable?

You have copied uImage to first partition in bananapi/bpi-r2/linux and modules to second partition (/lib/modules)?

Basicly folder-structure inside the archive

25

I don’t have some time… But I have do test.

I think that’s bridge do not run. hdmi do not run. I have a usb2serial-cable, but I don’t remember who :disappointed_relieved:

26

if you use lan0 as wan and bridging lan1-3 why not using wan as management-interface with fixed address?
