WLAN latency any good?

(1/4) > >>

Weaver:
I did some measurements of the timings for pinging my router over a wireless LAN. Could you tell me how these compare with your WLAN ? I'm using WPA2-PSK and did IPv4 pings below

--- IPv4 ping statistics ---
64 bytes: icmp_seq=0 ttl=64 time=4.794 ms
64 bytes: icmp_seq=1 ttl=64 time=43.95 ms
64 bytes: icmp_seq=2 ttl=64 time=27.174 ms
64 bytes: icmp_seq=3 ttl=64 time=29.226 ms
64 bytes: icmp_seq=4 ttl=64 time=3.45 ms
64 bytes: icmp_seq=5 ttl=64 time=43.282 ms
64 bytes: icmp_seq=6 ttl=64 time=55.626 ms
64 bytes: icmp_seq=7 ttl=64 time=35.226 ms
64 bytes: icmp_seq=8 ttl=64 time=33.965 ms
64 bytes: icmp_seq=9 ttl=64 time=28.499 ms
10 packets transmitted, 10 packets received, 0% packet loss
round-trip min/avg/max/stddev = 3.45 / 30.519 / 55.626 / 15.554 ms

I'm using a ZyXel NWA-3560-N WAP. The results with IPv6 pings are a bit different. The minimum is about the same, but the average is quite a bit higher. I should perhaps try to do both types with longer packets so that the packet size could be made the same.

Why the enormous variation?

The shortest time I’ve ever seen is ~2.5 ms, the longest is ~90 ms !

Hi weaver

I hope you don't mind, but I usually use fing from the App Store, which is very useful

Mine are 2ns min to 116ms max, where max is always at the very start

Fing also shows you graphically but I'm not sure if it's available for iPad, it is for iPhone

We usually use fing when we first look at a new network

Many thanks

John

Weaver:
Will definitely take a look at Fing. Btw, tried two different iPad apps, just in case the results were a red herring.

Weaver:
Fing app works nicely on an iPad. Big weakness, doesn't speak IPv6. Pretty much the same range of values obtained, so it's not a red herring to do with one particular app.

ejs:

--- Code: ------ 192.168.0.1 ping statistics ---
20 packets transmitted, 20 received, 0% packet loss, time 19025ms
rtt min/avg/max/mdev = 2.020/2.679/4.720/0.637 ms
--- End code ---

It's a nice simple 11g wireless router. The signal doesn't have far to go, only through a floor. I even reduce the tx power on my computer a little.
