wlan

While testing something with TFTP I noticed lots of timeouts (and slow speed as result) when I used my WLAN - and no problems when using a network cable. A quick test program sending/receiving UDP revealed that there are about 3-5% packets lost.

While it's obvious that WLAN has to be less reliable than LAN, I have no knowledge what loss rates are considered 'normal' - and when there is a need to further investigate the network infrastructure.

Are there 'typical' packet loss rates on WLAN (and other network technologies e.g. PowerLAN, WAN, ...?

Thanks
