ping or understanding problems

hi all,

i am new here, and hopefully right.
i am trying to configurate a routerboard rb411u as a client for my pc.
i have a wireless card r52 in station-pseudobridge (wlan1), which is one port of my bridge. the other port is my ether1 (here is my pc connected to the routerboard).
i have assigned an ip-address to bridge1 (10.1.1.215/24).
as my first test i’ve tried to ping from routerboard to my pc (10.1.1.115) and also to an other pc (10.1.1.1) which is on the other side of the wirless connection. both worked well.
when i ping from my pc to 10.1.1.1 it worked also, but from time to time the request timed out. in order to understand what the problem is, i started to ping from my pc and from the routerboard to 10.1.1.1 the same time. as a result i noticed that either the request from pc was timed out or the request from Board timed out. this is something i cannot understand. i expected to be able to ping from pc when the routerboard is pinging well, and if the routerboard is unable to ping it will be impossible to ping from pc. i am confused :confused:
can somebody tell me if this is normal, and when not maybe you can tell me what i have done wrong.

i searched the older posts to find a solution, but it seems like nobody ever had this problem. therefore i hope you can understand what i mean.
i have upgraded my software to 4.13 and also the firmware of the routerboard.

thank you in advance.

you can check for bridge interface mac-address. try to set auto-mac=no and set up value of ethernet interface as admin-mac= value

hi janisk,

thank you for your reply.
i assigned a mac admin-address to the bridge
i’ve tried different addresses 1: the mac of ether1
2: the mac of wlan1
3: a different one
i changed auto-mac to no

i still have the same problem ehter ping works from pc or from rb.
as far as i understand it should be possible from pc and rb at the same time.
am wrong with this??

thx

as far as my understanding of ICMP is - you send ICMP packet to the remote host and when remote host receives it, it responds with new ICMP packet in return to notify you that it received the packet. So, Ping should work in both directions if network is not of complex configuration (with loops and asymmetric pathways)
