Hello, I am trying to find help with my problem to get a reasonable connection of my desktop Medion Akoya P7700 D MD8848, which has a built in Ralink RT2860 card.
The HW is working, I have installed dual-boot on the computer. Under Vista the connection works without problems. And under Vista I was able to identify the built-in WLAN chipset.
However starting up Linux, everthing is fine only for the first couple of kB. The transfer starts at good speed - and then it gets stuck. Sometimes it can be repaired for another few seconds by de-activating the wireless network and then re-activating it. But it works only in 1 out of 10 cases.
Here are a few simple Linux commands I tried to get a status, but I honestly admit - I have no clue of the details of Linux or WLAN under Linux.

I also include the results of a ping, which I did while the transfer was stuck. Don't know why a ping works, while any other internet activity is stuck.

I would be happy, if someone told me what other diagnostic I should do, in order to deliver some reasonable description of the problem.
Thanks for any help!
