I have read a discussion about wpi driver in September this year. I have also a problem with the Intel 3945ABG, but the other kind. Symptoms: 802.11 connection is established smoothly and without interruption, however, any active tcp connections, which is fast data transfer, are interrupted in a few seconds. That is, for example, ssh connection is not interrupted (only sometimes), because it is not as active as, say, downloading files from ftp or http servers. This happens even if I did not move with my laptop (HP Pavilion dv6840er) in the next roomof home (10 meters-1 wall). Stable and fast tcp connection can be established only at a distance of 1-2 meters from the access point (dlink dwl g700ap in the bridge mode) and only stationary (then im not moving around with laptop). If i shift with laptop to 10-20 cm in any direction, smoothly or rapidly, the transfer of data in established connections is terminated. It was observed that the delays in icmp (ping) is not affected, that is, if im moving with laptop at home, the icmp answers is not increasing. I think this is because no connection in icmp request-reply. I admit that the reason may be in access point, but... Some info: connection to AP is OPEN wpi is not in the kernell 7.1-PRERELEASE #2: Tue Nov 18 19:34:00 MSK 2008 src/sys/dev/wpi/if_wpi.c,v 1.5.2.4 2008/03/18 18:52:52 # kldstat Id Refs Address Size Name 1 24 0xc0400000 41fbf8 kernel 2 2 0xc0820000 29d38 linux.ko 3 1 0xc084a000 2204c snd_hda.ko 4 2 0xc086d000 5c03c sound.ko 5 1 0xc08ca000 5558 acpi_video.ko 6 2 0xc08d0000 762b8 acpi.ko 7 1 0xc0947000 15d68 if_wpi.ko 8 1 0xc095d000 25f50 wpifw.ko 9 1 0xc0983000 711edc nvidia.ko 10 4 0xc5b5f000 18000 netgraph.ko 11 1 0xc5ba7000 3000 ng_ether.ko 12 1 0xc5baa000 6000 ng_pppoe.ko 13 1 0xc5bdb000 4000 ng_socket.ko # ifconfig wpi0 wpi0: flags=8843 metric 0 mtu 1500 ether 00:1f:3c:3d:8d:f1 inet 10.178.155.243 netmask 0xfffff000 broadcast 10.178.159.255 media: IEEE 802.11 Wireless Ethernet autoselect (OFDM/48Mbps) status: associated ssid onet channel 12 (2467 Mhz 11g) bssid 00:1e:58:2b:d8:c8 authmode OPEN privacy OFF txpower 50 bmiss 7 scanvalid 60 protmode CTS roaming MANUAL # cat /etc/wpa_supplicant.conf ctrl_interface=/var/run/wpa_supplicant network={ ssid="onet" bssid=00:1e:58:2b:d8:c8 scan_ssid=1 key_mgmt=NONE auth_alg=OPEN } Please help me out in this situation,i will be grateful for any advice.
