Anybody here on a wireless network? What's your latency?

[Viper GTS]

I was just helping a friend configure her wireless internet connection through her school's network. I didn't know the proxy settings so I couldn't finish for her, but I noticed something disturbing...

Her ping times out to the internet by IP were 700-900 ms! That's nuts!

Should latency on a wireless network be that high?

shouldn't be that high, probably the network you are attaching to.

wireless adds only abou 5-8 mills of latency.

My ping times are pretty near my copper network. Could there be major interferance in the area?

I dunno, I suppose it's possible.

She got the proxy settings, I'm having her run a speed test. 700 ms seems absolutely insane, what are they feeding this with, a 56K dial-up?

:disgust:

thats almost one second!

probably some overhead, interference, traffic, and location while you were testing it. I had similar problem from time to time with my laptop at work.

I didn't know it was that low. What about those wireless broadband things....like the Sprint deal?

 

[Windogg]

I assume she is using 802.11b and there is a hub somewhere in the dorm or classroom. Perhaps there are too many people per access point. Kinda like too many people on a hub. Have you tried pinging the proxy server and then an outside server to compare ping times?

Yeah how far is she from the access point, is it like a all over the university thing?

 

[Viper GTS]

AFAIK the network encompasses the entire campus, she isn't very far off campus in her apartment. Definitely within the area that's supposed to be covered.

I'm assuming it's 802.11b as well, but she hasn't been able to get me any concrete info from them. Ping times to the IP they gave her for her proxy address came back at 0 ms, which doesn't seem right at all.

I might call them & ask what exactly they're running...

I'm on a wide area wireless DOCSIS network. On a good day I get about 6mbit down and 3mbit up, average more around 1.5down and .75 up. I'm not capped per say, only by network traffic. Latency isn't a problem. It's slightly more laggy than a cable modem, but pretty hard to notice.
