I'm currently running freebsd-7.0-release GENERIC on a dell Inspiron 6400 (i386). I have a problem when networking via wifi. I have an intel 3945abg integrated card and I'm using the wpi drivers. I can connect to my wlan but after one minute or so of perfect connection the network starts to be terribly slow. I have tried pinging and I discovered that I have a 60% package lost when pinging something like google or other sites, that goes up to 90% or more when I increase the package size. When pinging my router or other computers inside my network I get even worse performances. (Something like 97% package lost or 100% if increasing the package size to something like 1400) With other OSes in my pc everything is fine, other pcs connect without problem. If I connect via etherneth to the same hub where the wifi transmitter is connected everything is fine. I have tried adding to resolv.conf, automatically generated by dhclient, the addresses of the DNSs of my ISP and browsing the internet has become a liiitle better, but still very far from the normal speed. And connecting to other pcs inside my network is still a pain.. Any idea? Thank you, Luca resolve .conf: nameserver 192.168.1.1 (my router) nameserver .......(my ISP DNS) #ifconfig wpi0 wpi0: flags=8843 metric 0 mtu 1500 ether 00:1b:77:23:a3:9e inet6 fe80::21b:77ff:fe23:a39e%wpi0 prefixlen 64 scopeid 0x1 inet 192.168.1.250 netmask 0xffffff00 broadcast 255.255.255.255 media: IEEE 802.11 Wireless Ethernet autoselect (OFDM/24Mbps) status: associated ssid Maldives channel 6 (2437 Mhz 11g) bssid 00:11:95:18:83:45 authmode OPEN privacy OFF txpower 50 bmiss 7 scanvalid 60 protmode CTS
