A couple of quesitons:
The MTU on the 8840 defaulted to 1480. I changed it to 1492, is this OK/required/not required?
What should the MTU on the WAN of the N16 be (defaults to 1500), or doesn't it matter?
Finally, I ran a trace route before and noticed that several times the first packet to the 8840 would report latency of several hundred milliseconds or more. e.g.
... over a maximum of 30 hops:
1 3 ms <1 ms <1 ms AsusRT-N16 [192.168.1.1]
2 467 ms 2 ms 2 ms 192.168.0.1
3 35 ms 74 ms 33 ms 222-152-216-x.jetstream.xtra.co.nz [222.152.216.x]
Any reason why this might be?
