Network error about WLAN (ping fails) on special device

[Michl]

My ping command to device "AXIS 5400+" (print server) fails if I activate/using my network card "Realtek RTL8191SE" (bridge) in Virtual Box (4.1.12r77245).

It's strange because a) on host system (win 7) pings are successful (to print server) b) pings (in VM) to other devices works well

If I change to my LAN card "Atheros AR8131" (in VM settings, bridge mode) and connect my print server directly, all works!?

For more details, please contact me.

It would be nice to get a solution. So, I can't print (over tcp) in my virtual machine :(

4.1.16 don't work yet

On 4.1.18 ping fails also. Is any developer interested to fix this issue??

Wireless network cards are special. To be able to connect to such a network device we have to do some tricks which is probably the cause of your problems. I don't see a chance to fix your problem in short term, sorry.

I suspect this is a manifestation of a bug with ARP replies fix-up that has been fixed in later 4.3 versions. Unicast ARP replies were not rewritten correctly. So your first two ping requests cannot be sent (host unreachable). Eventually the peer replies with a broadcast ARP reply and hence the next two pings are sent and you get the replies.

Marking as fixed. Please, reopen with more details if it's still a problem.
