I think that there is a problem with Linksys website.
I have V2 and wanted to look at whether I had the latest firmware.
I went to
www.linksys.com/uk and followed the products link. I then chose the "Access Points, Routers and gateways" link and then the BEFW11S4 link. Choosing firmware from the menu on the right seems to assume that you have version 3 of the BEFW11S4.
Firmware Date : 2/12/2004
Firmware File Size : 292 KB
Firmware Version : 1.50.11
Going through
www.linksys.com the same way gives you another screen that asks you what router you have via a drop down box.
Anyone else get this?
