What are typical ping times for a WLAN?

Is it typical that ping times be higher when ping'ing machines within my LAN because I'm using wireless clients and encryption on top of that?

ie. Computers "lan3" and "lan5" are wireless laptop machines on my LAN connected by a Linksys WAP54G, BEFSR41, WPC54G, and a DELL MiniPCI WLAN card. The first response is always high then the ping time are normal. Either at 1ms or 3ms.

When the response to the first in a series of pings is significantly delayed (or lost), then odds are that this is due to ARPing (and so is not refletive of actual round trip latency over the network medium.)

So by adding the static inet_addr eth_addr values to the table on each machine in my LAN will make ping show faster response times?

try one, let us know OK , thanks.

(im fixed ip everywhere, mac filter/wep128 on 1-laptop) Ping statistics for 192.168.0.21: ((& thru .28 all same zero ping to server client cards)) Packets: Sent = 4, Received = 4, Lost = 0 (0% loss) Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 0ms, Average = 0ms

If I ping router and/or 2nd wired ap I get first 14ms then 0 0 0 = 3ms average

Yeah, for those "initial" pings --- but maintaining all your nodes' ARP tables manually hardly seems to be worth it, unless you have more free time on your hands than I can imagine ...
