Same old same old.....

I've read several similar episodes, but am still not sure how to
proceed. I recently upgraded a win98se sys to Winxp home w/o issues.
This is wired to a cable modem (comcast). This works fine. I recently
upgraded an old GW system (cel 466) running win95 os2 to Win98se (clean
full install). This is my remote rig. I connected a Netgear MA814 v2
wireless router to the first system runnig xp as per instructions. All
the lights come on like they should. I setup the router the way the
help file/setup wizard suggests. The old remote rig has been fitted
with the usb wireles Netgear MA111 (all this stuff was dirt cheap last
week from CompUSA). It installs just fine with a l'il help from my
Win98se CD. The adapter card receives the signal from the router (60%),
and originally I was able to share the broadband connection (it went to
MSN and d/l'd about 17 critical updates). I had to reformat this rig
for some other OS problems. Now I can occassionally receive a signal
from the router, but not share the broadband connect. I've tried
several settings changes/ reinstalls, but no joy. Wherever I could I
checked "direct connection to the internet." Would someone like to walk
me through a fix before I return this gear to CompUSA. Cheers

I bought the homeXP with sp2 version. There is no b4......;-).
Wherever I've seen this phrase "I connnect through a local area
network", I've selected it. On both OS's. The updates were for the rig
running Win98se.
