Ural0 Connectivity Issues

[Olivier Wouters]

Hi,
I am relatively new to FreeBSD (I use 6.0-RELEASE-p6) having only used 
it for approximately 2 months, and have run into a little bit of a 
problem with my wireless setup.  I am currently using a WUSB54G ver. 4 
(Linksys Wireless-G USB network adapter: 
http://www.linksys.com/servlet/Satellite?c=L_Product_C2&childpagename=US%2FLayout&cid=1115416827517&pagename=Linksys%2FCommon%2FVisitorWrapper)
with the router ( a Linksys WRT54G Wireless-G Broadband Router) being 
downstairs.  My particular network adapter uses the Ralink RT2500 
chipset, and the Ural driver, which was ported over from OpenBSD, 
supports this particular chipset.   I have gotten ural to work on boot 
by adding the following into /etc/rc.conf: ifconfig_ural0="DHCP netmask 
255.255.255.0 ssid holo wepmode on wepkey 0x[wep key] weptxkey 1".  
However, my connection is rather poor to my router, with my connection 
strength staying at 7%, intermittently jumping up to 85% every now and 
then.  I can't quite understand why my connection is so bad, and it is 
irritating me as I often lose connection entirely and am forced to as 
root run the the ifconfig line and then dhclient ural0 to regain 
connection.  Here is the output of dmesg for my nic and usb:

$ dmesg | grep usb
usb0: <Intel 82801DB (ICH4) USB controller USB-A> on uhci0
usb0: USB revision 1.0
usb1: <Intel 82801DB (ICH4) USB controller USB-B> on uhci1
usb1: USB revision 1.0
usb2: <Intel 82801DB (ICH4) USB controller USB-C> on uhci2
usb2: USB revision 1.0
usb3: EHCI version 1.0

usb3: <Intel 82801DB/DBL/DBM (ICH4) USB 2.0 controller> on ehci0
usb3: USB revision 2.0
$ dmesg | grep ural0
ural0: Cisco-Linksys Wireless-G USB Network Adapter, rev 2.00/0.04, addr 2

ural0: Ethernet address: 00:12:17:75:c8:a8
ural0: if_start running deferred for Giant

Has anyone encountered similar difficulties or happen to know what may 
be the cause of this problem.  I had no problems with connection or 
connection loss in Windows XP, so i am quite clueless for this strange 
connection loss and low connectivity.  Thanks in advance for any aid.
