RT-AC68R trouble connecting to peers on local wireless network

[veggiebenz]

I have RT-AC68R with 374.43_2 (Merlin build).

I have a raspberry pi on the network, connected thru edimax wifi adapter.

When I try to ping from OSX, i get a bunch of these:

$ ping 192.168.1.72
PING 192.168.1.72 (192.168.1.72): 56 data bytes
Request timeout for icmp_seq 0
Request timeout for icmp_seq 1
Request timeout for icmp_seq 2
ping: sendto: No route to host
Request timeout for icmp_seq 3
ping: sendto: Host is down
Request timeout for icmp_seq 4
ping: sendto: Host is down

Then after a couple of minutes it starts to return ping. No discernable pattern - sometimes after 40=-50 tries, usually 130-140 at most.

ping: sendto: Host is down
Request timeout for icmp_seq 129
Request timeout for icmp_seq 130
64 bytes from 192.168.1.72: icmp_seq=131 ttl=64 time=66.406 ms
64 bytes from 192.168.1.72: icmp_seq=132 ttl=64 time=6.358 ms
64 bytes from 192.168.1.72: icmp_seq=133 ttl=64 time=2.055 ms

Then i can connect / ssh etc.

A couple things are odd about this.

1) My old router had no difficulty at all - I would always be able to ping and connect to the raspberry pi immediately. No settings have changed on RPI.

2) There is a way to ping the RPI from the ASUS router itself -- this always is able to connect immediately, so there is no issue with Pi waking up.

PING 192.168.1.72 (192.168.1.72): 56 data bytes
64 bytes from 192.168.1.72: seq=0 ttl=64 time=40.756 ms

64 bytes from 192.168.1.72: seq=4 ttl=64 time=31.147 ms

--- 192.168.1.72 ping statistics ---
5 packets transmitted, 5 packets received, 0% packet loss
round-trip min/avg/max = 31.147/67.002/111.651 ms

3) once I am connected through the above method, if i am inactive with the connection (this time about 10 minutes), I will lose connectivity and I will have to do the ping exercise again.

Any ideas would be much appreciated.

Thanks

I have also tried new Firmware Version:3.0.0.4.376_1665, with same symptoms.

Also, trying to connect to my daughter's ipad running minecraft PE - it can see her server but hangs trying to connect.

EDIT: This turned out to be a bug in minecraft 0.90

Still have the same problems. Reset to factory defaults for kicks, did not fix my issue.
