jpg update causingwireless connection problems?

[Rod]

Hello...my first time here so I'll probably be very naive. I downloaded and
installed the recent jpg security update for Office XP Pro. Immediately after
the instllation, my wireless network connection became limited to the degree
that I was no longer able to access the internet. If anone else has
experienced this and/or has fixed the problem , I'd sure ppreciate hearing
from you.
Thanks,
Rod
