Slow Ipod wifi on lan

moneyuser

Hi

I have tried several Ipods on several different LANS and they all appear to suffer terrible network speeds, e.g. I pinged my ipod from my PC and got these times

When I ping another PC I get < 1ms so I know it's not the network, and as I say I've tried different LANS anyway and also different Ipods.

Is there any way to improve the Wifi speed of an Ipod on a LAN?

Thanks

Is this an issue for any 'real world' applications?

Yes it is as these devices will be used to run a web app that will be used for taking orders in restaurants.

... and you'll notice a difference between a 1ms response and a 38ms one ???

(I'm guessing that 38ms is the average of all the times you quoted - same applies for whatever the true average is....)

:rotfl: Blink and you'll have missed several, average blink is 300-400ms

PC is hardwired to the network ipod is wireless of course it will be slower, what speed is the wireless part of the lans you tested this out on?

Thanks for doing the maths for me.

I could see the difference being an issue for high-usage applications with loads of transactions , but for pinging orders between table and kitchen in a restaurant....?

I'm not reading this wrong, we are talking milli-seconds here, aren't we.... one thousandth of a second?

Well if you are I am , but ping always reports millisecs ... and the first measurement allows for the overheads in the transport layer ie MAC address, route etc....

The PC I tested was wireless. The router speed is G. I've tested b and g wireless cards on the PC. Both speeds are fine. The ipod is v2, so is b I think.


The difference is noticeable. Wireless PC works fine, Ipod does not (slow to retrieve menu items, saving order, printing).

Therefore a difference between < 1ms and the ipod times is the obvious place to look to solve the problem.

Why?

If someone showed you the difference between a 1ms and 300ms response time, would you see it? Probably not. If the difference between one device and the other in real-world use is noticeable in terms of whole seconds, and the difference between ping times is 299 milliseconds (less than 0.3 of a second, if my maths is sound....), I'd suggest the problem lies elsewhere.....

ipods won't be able to process the data or move it around as fast as the pc, I suggest that's got more bearing on the overall performance than the wifi ping times
