Finding My Router IP Address - BiggyTwo

Hi All,

Windows Xp home; Nexxt Wireless Adapter; Laptop - Broadcom 802.11 b/g
adapter; Router- Linksys WRT54G.
In our home network I am seeing all the signal strength bars but
cannot connect to the internet.  Sometimes I get the limited or
connectivity message with 2 bars.

Question: I know the Hostname is "SunnyBoy" How can I find the IP
address to check the router settings using the Browser without
physically resetting the router?  I know it is not the default value.

Any suggestions on the connectivity issue?  (I read some articles
already on the net.)

Much thanks,

Biggy
