ethernet wireless bridge WET 54G: IPconfig seems to work, but cannot get to setup

I have a WET 54G Linksys Bridge (wireless to ethernet port/hardwire)

My colleague was able to access and set it up successfully using my laptop prior to my leaving for a business trip, which i'm on now.
(I;m at the location where i'll be using this for a month, the reason i got the bridge)
I have the same laptop but a different switch to interconnect.  Neither my laptop nor tower can "see" the device.  I"m using 192.168.1.226 as the IP address (in a browser window in addition to trying to PING).  Also, the wizard on the installation CDrom cannot see it.
I need help for steps to try to debug the connectivity.  I am optimistic that once i get connnectivity, it will work (it worked fine before leaving for this trip)
ANy suggestions?

p.s.  the non-visitbility is the same from either my tower or laptop.
From my tower(the one i'm trying to connect), interestingly, ipconfigure shows :
dhcp enabled
autoconfiguration ip addr 169.254.195.109 (compared with laptop's direct wireless connection here: 169.254.195.109)
subnet mask 255.255.0.0
default gateway 169.254.195.109  
So i'm guessing that there's some connectivity.
Also, the switch's port ethernet LED lights and extinguishes when i connect and disconnect the cable at the tower's connection

please suggest any debugging steps or corrective action...

thanks
