FC3, ndiswrapper .12, and LinkSys WMP54g v4 (RaLink) problems

at first this was just a basic problem: wireless card wasn't working in fc3, however; now that i have exhausted all my ideas i'm turning to the forums for an answer (hopefully). i'm running fedora core 3 (2.6.9-1.667) with a LinkSys WMP54g v4 (with the RaLink chipset... not whatever they have changed to for the new v4's).

i am not new to linux (i have been using mandrake/redhat/slackware since about 1998) so i know how to get around. however, i have never had the internet on my linux boxes because i always manage to get a win modem that will not work with linux (and i'm too lazy to buy a new one...), so this whole thing could be my lack of a networking background (but i doubt it). i have read everything (google, news groups, lugs, forums, ldp howto's, etc...) on wireless networking and any problem even remotely connected to wireless cards in linux, so no rtfm here

here's what i have tried:

to start off i find my chipset.

[root@localhost ~]# lspci
00:00.0 Host bridge: Intel Corp. 82845 845 (Brookdale) Chipset Host Bridge (rev 04)
00:01.0 PCI bridge: Intel Corp. 82845 845 (Brookdale) Chipset AGP Bridge (rev 04)

02:0b.0 Multimedia audio controller: Creative Labs SB Live! EMU10k1 (rev 07)
02:0b.1 Input device controller: Creative Labs SB Live! MIDI/Game Port (rev 07)

with that i go read everything i can find on wireless networking and installing wireless cards. i grab ndiswrapper 0.12, driverwrapper 2.23, the Ralink drivers for windows and linux from their site (since i read about people having problems with the LinkSys ones who got the Ralink drivers to work), and
the drivers from a-link (dot) com which i found out about from another linksys thread here titled "Linksys WMP54g help with hang" (i can't post links). with all those copied to my linux drive i figured installing the Ralink linux drivers would be the best option; however, i have no kernel source and didn't get the SRPM discs, so that will have to wait.

so i go with plan b, which is to install ndiswrapper. ndiswrapper compiles, installs, and loads the LinkSys windows drivers without a problem:

now at this point i noticed that iwconfig wasn't reporting the proper settings, but iwlist was (this is a brand new wireless tools package (downloaded about 3 days ago). except for the fact that my router's mac is 00:12:17:1A:BF:AD, not xxxx:AF. i figure i should
just be able to change that, run dhcp, and have a working connection. so i run iwconfig:

[root@localhost ~]# iwconfig wlan0 AP 00:12:17:1A:BF:AD

which does nothing. another scan says my ap is the same.
i figure i'll try dhcp anyway and see what i get.

[root@localhost ~]# dhclient wlan0
Internet Systems Consortium DHCP Client V3.0.1

DHCPDISCOVER on wlan0 to port 67 interval 4
DHCPDISCOVER on wlan0 to port 67 interval 8

i get nothing. thinking it might be dhclient (i read about some people having problems with it) i get dhcpcd. but dhcpcd wlan0 does nothing (the cursor just sits on the new line and blinks).

checking route returns:

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface * U 0 0 0 lo

my router's internal ip is
out of couriosity i ping but it has 100% packet loss (i do have a firewall on... but by the time i took it down i had other problems too so...) and i can't ping my router. i decided i would just edit all the files i needed manually but either my resolv.conf file contains nothing or something is up with it because nautilus/gedit couldn't open it and cat returns nothing. so before i go screwing with it i try route

route add default gateway fails with:
SIOCADDRT: Network is unreachable

and i can't remove that, everything i try returns:
SIOCDELRT: Invalid argument

since i read that the problem might be that the windows drivers need at
least 12k stack sizes and fc3 kernels only use 4 (and fedora removes the
option in the kernel for the stack size) i tried removing ndiswrapper and
installing linuxant's kernel. however, after doing that the kernel does freeze on modprobe ndiswrapper and the dhcp clients both segfault. i try rebuilding ndiswrapper just in case but on compiling i get "undefined symbol: get_user_size" compile errors.

i gave up on using ndiswrapper here and decided to go get the kernel source
and try the native drivers. throughout the above i tried:
kernels: 2.6.9-1.667 (fc3), 2.6.9-1.667stk16 (linuxant), my own customized 2.6.9 (with a stack size of 128kb - just to be sure
ndiswrapper 0.12 and 1.0rc2 with all the above kernels (except mine - explanation below)
and all the combos of the two kernels and two ndiswrappers with all four of the windows drivers (linksys winxp, ralink winxp, ralink win 2k (i heard they worked for some people), and the driver)
nothing worked.

so after getting the srpm discs and attempt to build the fc3 kernel source (but not install... i just needed them compiled) and get a scsi error:

/usr/src/linux-2.6.9/drivers/scsi/qla2xxx/qla_os.c: In function `qla2x00_queuecommand':
/usr/src/linux-2.6.9/drivers/scsi/qla2xxx/qla_os.c:315: sorry, unimplemented: inlining failed in call to 'qla2x00_callback': function not considered for inlining

make[3]: *** [drivers/scsi/qla2xxx] Error 2
make[2]: *** [drivers/scsi] Error 2
make[1]: *** [drivers] Error 2
make: *** [_all] Error 2

after going through the kernel config and trying 2 different ways of compiling i give up on the fc3 kernel. i go get the sources for a general 2.6.9 kernel from and try compiling those, but i get the same error. after 2 more compile attempts i figure i'll just use the libs dir because it should be very close if not the same to the fc3 sources anyway (depending on config). with that the RaLink linux driver compiles, i install it, and ra0 shows up. i reboot the machine and kudzu detects the card, however; it fails when trying to set it up and prints messages about delaying the card. lsmod shows the rt2500 driver installed so i try to configure the card myself with iwconfig but it says there are "no wireless extensions" on ra0. i try dhcp just to see what it says and it complains about the card not existing.

so after all this the closest i got was with the ndiswrapper/dhcp problem in the first place. so... if anyone has any ideas on this pass them along, i will be extremely gratefull if someone gets this going.

ok people... i fixed it... anyone with a large fish feel free to start swinging...
although i read all the man pages, etc i could find i was skipping one step; a temporary static link from my card to the router for setting up the dhcp routing.
