Now I haveall do with my bpi-r2, but not the gateway. It’s run with your debian. I have server, wifi (with hostapd…) but if I do a gateway between wan and lan[0-3], the network in lan[0-3] is not very good. I don’t understand why. I have this problem witj debian or ubuntu. I have not tested other.
what means not very good? how do you test? how is your current config?
what have this todo with gateway?
can you please make more effort when creating threads or qustions? it’s really hard to know what do you want to do and whyts the problem
I have say all I have do. The ping between my computer and the bpi-r2 is not good. Internet is very slow.
I do not know what to test to understand.
what means not good? have you packet loss or high rtt? have take a look in dmesg?
can you show us the ping? which interface do you ping how is your network-setup (client,r2,switches,connection-points)
have you tested directly connected to r2 without any other equipment (only 1 cable)?
When I test the connection in the “lan” I have only 1 wire between the computer and the bpi-r2. I have 3 wires for the test : 1 black, 1 white and 1 yellow. I have try the yellow and the black between the bpi-r2 and internet (the network of my modem 192.168.1.XXX) : this 2 wires are good. I can do ssh with the bpi-R2 if my computer is in the network 192.168.1.XXX. I have put wan, lan0… in the network with my modem (192.168.1.XXX) : it was always good.
The bpi-r2 manages the 192.168.2.XXX network with a bridge where there is ap0.
If I use the wire (black, white or yellow) to do a ssh in the network 192.168.2.XXX, and I do “dmesg”, the display blocks and starts again after a pose. I have try this with 2 PC 1 mageia 7 (testing) the other mageia 6 (stable).
If I use the wifi (hostapd in ap0) to do a ssh, and I do “dmesg”, the display is instantaneous (try only with mageia 7).
With the network 192.168.1.XXX I can do “dmesg” instantaneous.

which interfaces have you bridged?
do not bridge wifi and lan to wan

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 :

rtt min/avg/max/mdev = 0.269/0.334/0.490/0.038 ms
If I ping the modem with my computer :

115 packets transmitted, 113 received, 1% packet loss, time 115951ms
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?
Oups… A switch ( D-LINK DGS-108 ).
you have connected only 1 port of bpi’s lan-ports to the switch? have you tested with another port? and without the switch?
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.
Have you tried without bridge and different port?

Why ???
I don’t know if you can bridge wan to lan…but at least this line should be dropped from your config
allow-hotplug wanI 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.
With or without the wifi in the bridge, it works better when the network does not go through the bpi-r2
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?
I have less Packetdrops. But I have.

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.
