"ping" shows different delay from two computer on the same network


I am using "ping" on 2 computers on the same wifi network.
One of them shows a bigger delay than the other consistently.
I am trying to find out what may be the problem.. Can someone suggest
a way to investigate this issue or isolate the problem?
Both of them sending "ping" at almost the same time.

First laptop (much newer laptop model)

Code:
PING www.l.google.com (64.233.181.104): 56 data bytes
64 bytes from 64.233.181.104: icmp_seq=0 ttl=48 time=1011 ms
64 bytes from 64.233.181.104: icmp_seq=1 ttl=48 time=1033 ms
64 bytes from 64.233.181.104: icmp_seq=2 ttl=48 time=648 ms
64 bytes from 64.233.181.104: icmp_seq=3 ttl=48 time=1081 ms
64 bytes from 64.233.181.104: icmp_seq=5 ttl=48 time=1027 ms
64 bytes from 64.233.181.104: icmp_seq=6 ttl=48 time=1051 ms

----www.l.google.com PING Statistics----
8 packets transmitted, 6 packets received, 25.0% packet loss
round-trip (ms)  min/avg/max/med = 648/975/1081/1030
Second Laptop:
Code:
$ ping www.google.com
PING www.l.google.com (64.233.181.104): 56 data bytes
64 bytes from 64.233.181.104: icmp_seq=0 ttl=48 time=51 ms
64 bytes from 64.233.181.104: icmp_seq=1 ttl=48 time=49 ms
64 bytes from 64.233.181.104: icmp_seq=2 ttl=48 time=49 ms
64 bytes from 64.233.181.104: icmp_seq=3 ttl=48 time=49 ms
64 bytes from 64.233.181.104: icmp_seq=4 ttl=48 time=102 ms
64 bytes from 64.233.181.104: icmp_seq=5 ttl=48 time=48 ms
64 bytes from 64.233.181.104: icmp_seq=6 ttl=48 time=48 ms

does the problem caused by the RSS? hummmmm... I mean, this caused by the network card's different process ability!
I am not sure about this, Just guess!

Are there same OS right? I think may be a first NIC got a problem perhaps driver incompatible with the device.
