Hello,
I am very new to the Mac world because I have just bought an iMac Core Duo 17" (and it is very, very great!). But I have a problem with the wifi connection.
When I booted for the first time, my WPA-encrypted wifi network was successfully detected and I was asked to enter the key. All went well.
But I noticed and notice a strange thing: the downloading speed varies from a high speed to a very low speed (near 0 KB/s) and vice-versa all the time. Moreover, web pages take more time to load than from another computer on the same network; and while pinging a machine on the same network the latency varies from 0 or 1 ms to ~250 ms.
All other computers on the same network, wired or not have a 1 ms latency with other computers and download constantly at around 4 or 5 MB/s on the LAN, and at around 600 KB/s on the 'net. Compared to this normal behaviour, my iMac downloads at an average speed of 200 KB/s on the LAN or on the 'net, and pings other machines with an average latency of 100 ms
=> Look at the screenshot attached to this post. At the bottom of the "Moniteur d'activité" window, you can see a graph showing the varying speed (green line); and in the "Terminal" window you can see low-to-high latency ping to a networked computer.
This is annoying and have only one idea (not sure at all) of what this strange behaviour could come from: the MTU parameter?
But if the MTU parameter is the problem, I don't know how to solve it.
Any help or even idea is welcome,
Thank you.
