So, I have a D-Link DIR-615 wireless router at my office, set up in "bridged" mode (LAN only), WPA pre-shared key. The problem is that while N9 can connect to the network and gets a DHCP lease, mail web etc times out. I get no replies to ping (either way), same for ARP unicast requests to N9. However ARP broadcast works.

Attached are dmesg and syslog output from a connection attempt.

Interestingly, I tried to reboot the router, and voilà - everything worked perfectly... for about five minutes

I wonder if this is a problem with the router, N9 or maybe both? iPhone and SGS have no such issue.
