What hardware version WRT54G router? Look on the serial number tag.
Extra credit for the firmware version.

Sure you can. There's data over phone lines, power lines, and CATV
coax. HomePNA, HomePlug, etc.

It takes two to tango and to do wireless. Buy an "ethernet wireless
cleint bridge". See:
<http://wireless.wikia.com/wiki/Wi-Fi#Wireless_Ethernet_Bridges>
for a partial shopping list of likely candidates.

What hardware version BEFW11S4. v4 sucks.

Nope. They won't talk to each other. You need something that has a
bridging or client mode. A wireles router that supports WDS (wireless
distribution system) will also work:
<http://en.wikipedia.org/wiki/Wireless_Distribution_System>
Your WRT54G *MIGHT* support DD-WRT firmware, which includes WDS
support:
<http://www.dd-wrt.com/wiki/index.php?title=WDS_Linked_router_network>
One gotcha is that some implimentations of WDS will only work with WEP
and not with WPA or WPA2 encryption. WEP is not very secure.

No 3rd party firmware for the BEFW11S4. Besides, it's 802.11b only.
Find something else.

Sorry Jeff, data over unshielded cables to a radio shack is an
anathema to a ham or swl (QRN).

I beg to differ. There's a big difference between BPL and HomePlug
even though they use similar technology. Outdoor power lines are
widely spaced and cannot really be considered a "twisted pair". CMRR
(common mode rejection ration) sucks and the power lines radiate. The
power used by the xmitters are also quite a bit higher than the home
version.

However, in the home, the power lines are much closer together and are
a better approximation of a twisted pair. They radiate considerably
less. Note that HomePlug really does meet -52dBm/Hz FCC transmit
power density limitations. That's about 50mw spread between 4-20MHz.
Some models even have notch filters in the ham bands.

<http://en.wikipedia.org/wiki/Homeplug>

I've done some sniffing around various hams houses trying to find the
sources of QRN (noise). In most cases, it's noisy switching power
supplies (i.e. cell phone chargers), laptop chargers, plasma TV's, and
computahs. Although several hams had HomePlug 1.0 systems, there was
no evidence that they were causing any QRN. Incidentally, an Icom
IC-756 Pro II transceiver showed the presence of HomePlug RFI on the
spectrum display, but it was barely noticeable.

I've done little with HomePNA (phone line networking). MoCA and other
forms of CATV networking is safe because the coax is shielded.

Err, that should "sucks more than the other versions, which also suck."

Like any of the ones listed on the dd-wrt.com website as being compatible.
