Linksys WRT54G problem after updating firmware

I have a WRT54G connected to our main LAN to give wireless access to
our users. Our main LAN is driven by a Cisco 2651 and Cisco switches.
We have a command in the 2651 to route the appropriate traffic to the
WRT54G. This worked perfectly until I upgraded the firmware to the
current 4.20.7. I think I used to have 2.04.7.
My problem is that I can no longer see wireless clients, or the
WRT54G config page, from the main LAN. I used to be able to access the
WRT54G from it's address on the Cisco network, 192.168.0.187 or by its
own rotuer address of 192.168.9.254. Now I can not access either from
the main LAN and I can only ping it on the 192.168.0.187 address, I
used to be able to ping both.
I am thinking it has something to do with the firmware, since it
worked fine prior to the upgrade. I have the firewall turned off - it
does not appear to be a setting. Any idea?

Thanks,

Chris.

1. What hardware version of WRT54G? I could probably figure it out
from the firmware version, but I'm lazy today.

2. Your upgrade of the firmware reset all the settings. Your WRT54G
is now at the default IP of 192.168.1.1. You probably also lost all
your other configuration data. Did you make a backup of the setting
before the upgrade?

Hardware is verison 2. Actually, most of the settings were retained
after the firmware upgrade, but as per Linksysy tech suppoprt I reset
the router and then changed all the serttings back to the way they were
previously. As a test I have also tried to get our other branches
routers on the network and they do not want to cooperate either. They
are all at 3.03.1. Again - they work great as far as the wireless
client is concerned. The wireless client can ping anything on the main
network, but we can not get back thorugh to the wireless client from
the main network. Seem like some extra security measure in the newer
firmwares, but I can not figure it out.

Thanks.

What version of the hardware do you have, and does 4.20.7 match that
hardware?

Fixed it - I do not remember doing this before, or having to do this
before, but I changed it to router mode from gateway mode and all is
better. For some reason I still can not access the admin page via the
LAN address now, but I can from the Router IP. The important thing is
that I can access the clients again.
