Summary: I purchased the WRE54G version. 2.0. Unlike the version 1.0, the version 2.0 has a RJ45 jack (Ethernet jack). This allows you to connect it directly to the router for setup.

The unit comes with a choice of two power cords. One allows you to directly plug it into the wall and the other has an approximate 6 ft cord. This is a very nice feature and it also uses wall power and not an adapter.

Like other reviews, the setup using auto search from the CD is useless. The only good about the CD is the user manual on it. It would have been very simple for Linksys to create a quick setup sheet using pages 14,15 and 23 of the user manual. Basically the instructions should be like this:

1) Make sure a PC is either directly or wirelessly connected to the router.
2) Using a web browser, login to your router from the PC and change its’ IP address to 192.168.1.1 then logout. You may have to unplug or reset the router afterwards.
3) Using the supplied RJ45 cable (Ethernet cable) plug the WRE54G into one of the RJ 45 ports of the router.
4) Using a web browser, login to your router at 192.168.1.1 and change the DCHP range to go from 192.168.1.2 through 192.168.1.240.
5) Using a web browser, login to the WRE54G at the factory default IP address of 192.168.1.240. It will ask for a user name and password. The default user needs to be left blank. The default password is: admin.
6) Setup up the WRE54G. For security you should change the login default password.

Once the WRE54G is setup you can change its’ IP address. This can only be done once it is setup because the default address is 192.168.1.240

Summary: Here are good instructions -> throw away the quick installation guide

To connect to the device, change your IP address to 192.168.1.99 with a subnet of 255.255.255.0

Using your Windows Wireless Network Connection, browse the availble SSID's and connect to linksysXXXXcc.

Open an internet connection to http://192.168.1.240 login with password admin

Change the password page first and save. Then Change the settings page to match your network.> > > Here is an important clue> > > Change the channel, SSID and WEP(IF USED)to match your existing wireless settings along with IP address, subnet and gateway.

I don't recommend using the autoconfig button on the Extender unless your the type that took your wireless router out of the box, plugged it in and is happy.

Summary: Had this unit running is 30 minutes - would have been quicker had I not tried the CD guide (had to try based on the reviews). Without security, the auto config worked first time out of the box w/o firmware upgrade or tech support. With security, couldn't get it setup using CD approach. I reset the unit, connected to the wired network, called up the utility using the default IP from the user's guide (192.168.1.240), set the parameters, and it came right up, blue lights and all. I walked around the house with the laptop and got very good to excellent signals at or near 54Mbps. My advice? Use the web based utility to set your SSID, channel, g only (unless you have 11b stuff), security enable, key number, code, shared (I use 128 WEP). I also bookmarked the page so I can easily change key periodically. My AP is a Motorola SBG900 wireless cable modem.
