How many walls are they going through between the unspecified model
wireless router and whatever style of computer they're using in the
living room. In general, you can go through one wall fairly easily.
Two walls are a crap shoot. Three or more are very difficult. If
there's aluminum foil backed insulation in the inside walls, forget

Ok, you have cable modem service. Thanks.

The basics... Find the connection manager on your unspecified model
wireless client adapter and get the wireless connection (or
association) speed. With 802.11g, it will vary between 1Mbit/sec and
54Mbits/sec. The actual thruput is half or less the connection speed.
Note that the connection speed can be different in each direction.
When I see the upload greater than the download, I look for RF
interference at the client end. Wireless camera, TIVO, security
camera, cordless phone, etc?

It might be haunted. Please consult an exorcist or building

It's easy. Just find either a wireless access point or ANY wireless
router. Run a CAT5 cable between your existing unspecified model
wireless router and the 2nd wireless box, from LAN port to LAN port.
On some ancient models, you might need to wire one end of the cable as
a cross-over cable.
The setup on the 2nd wireless box is detailed here:
You'll also find the same thing on the manufacturers support web pile.
There are some decisions to make. You can use the same SSID for both
wireless access points, and hope that you'll get seamless roaming. The
reality is that you probably won't unless the access points are
identical, and support 802.11r:
With a random mix of access points, it probably won't work. Note that
this is fast BSS switching, not seamless roaming. You'll loose a few
bits during the disconnect and reconnect cycle, but it won't loose the
The client software must also be compatible for roaming to work. Many
clients will tenaciously stick to the initial access point connection
and not switch to a stronger signal, unless you first disconnect. Even
worse, some will remember where they connected last, and will
reconnect even if it's the weaker signal.

It can be done. Have your checkbook ready.
Instead, I suggest you give up now while you're still sane. Pick two
different SSID's and two different non-overlapping channels (1, 6, 11)
for your two devices. If you want to switch location, disconnect, and
reconnect to the desired SSID. If your parents have a difficult time
with this, you might be able to automate it with a script.

Yeah, that's a worthy goal. One should always be downloading
something while walking around the house. However, I don't know of
any consumer grade hardware that will do 802.11r. I can probably find
something if you give me a clue as what you currently have to work
with and how roughly how much money you want to spend in order to
waltz around the house while downloading.
