Hi all,

I just installed a small wireless lan at home using Netgear wireless cards
and the setup seems to be a little slow to me.

My setup is

Machine 1
  Pentium II 350MHz
  FreeBSD 4.6-STABLE from a couple of days ago
  MA401 wireless card in a MA301 wireless PCI adapter
  running in hostap mode
  I've turned wep off.

  The card shows up as

    wi0: <Netgear MA301> port 0xe000-0xe03f,0xdc00-0xdc7f mem
        0xee001000-0xee001fff irq 5 at device 18.0 on pci0
    wi0: 802.11 address: 00:30:ab:1a:06:c6
    wi0: using RF:PRISM2.5 MAC:ISL3873
    wi0: Intersil Firmware: Primary 1.00.07, Station 1.03.06

  /var/run/dmesg.boot doesn't show any conflicts.

  ifconfig wi0 tells me

    wi0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 192.168.2.1 netmask 0xffffff00 broadcast 192.168.2.255
        ether 00:30:ab:1a:06:c6
        media: IEEE 802.11 Wireless Ethernet DS/11Mbps <hostap>
        status: associated
        ssid GavinsHomeNetwork 1:GavinsHomeNetwork
        stationname "FreeBSD WaveLAN/IEEE node"
        channel 3 authmode OPEN powersavemode OFF powersavesleep 100
        wepmode OFF weptxkey 1
        wepkey 1:128-bit wepkey 2:128-bit wepkey 3:128-bit wepkey 4:128-bit

  I've forced the card to 11Mbps, without this setting it was flapping
  between 1Mbps, 2Mbps and 5Mbps.

  The singal cache is
    chip# wicontrol -C
    [1/1]: 00:30:ab:1a:06:d1, 192.168.2.2, sig: -95, noise: -143, qual: 48
    chip#

Machine 2
  IBM Thinkpad 380Z
  Windows XP Professional
  MA401

  The card seems to stay set on 5Mbps.

The machines are about 1.5 metres apart and the two cards have line of site.

File transfers between the two boxes are slooooowwwww. FTPs and samba
transfers
lurch along at 36 KBytes per second.

Any ideas what I can tweak to get some decent speed out of the network?

Thanks in advance,
Gavin
