I have a Linksys Wireless Router, WRT54G, that I'm using to link to other
computers and to a DSL modem. While I'm fairly satisfied with the
performance of the wireless link with my Dell Inspiron 600m, I think it
might be nicer still if the range extended beyond about 30-40 feet or so.

Linksys is offering a high-gain antenna for this router and some of their
other wireless G products. The Linksys antenna kit, HGA7T, is claimed to
have a 7dBi gain. No speculation on how much that might improve range.

Another product offered for Linksys wireless routers is from Radio Shack.
Catalog #: 278-844. This product is claimed to have a gain of 5.5 dBi.
Slightly less gain than Linksys and at a slightly lower cost.

Has anyone tried either of these products? Pros? Cons? etc? Does the high
gain come at the expense of response pattern? For example, I currently have
coverage on two floors of the house. Would a high-gain antenna improve
coverage upstairs while sacrificing portions of the basement?

I'm not sure that an antenna is the best solution for my setup. The cheapest
thing would be to simply move my router since I suspect that the path that
I'm trying to punch a signal through has some serious problems. I also
wonder if the miniPCI card in the Dell has the range of a full-size wireless
card. However, a stronger signal is almost always preferable.

RKHenry,

I have the same Linksys router, and I tried their high-gain HGA7T
antenna to provide a stronger signal on my new 2nd floor deck. The
improvment in signal strength was marginal...not worth the $69.99,
in my opinion. Now I'm thinking of moving the route closer to the
deck.

It also depends on where the router is vertically. This antenna probably
achieves its gain by increasing the signal in the horizontal at the expense
of the vertical (with the antenna pointing up). The router should have two
antennas and only one is in use at any given time. Try rotating one of the
antennas.

To all who responded, thank you.

I think I'll pass on buying either of these high-gain antennas and save the
money. It's cheaper to just move the router.

The idea of a reflector intriges me though. It might be fun experimenting
with that.

I sometimes wonder about the wisdom of combining a wireless AP with a
router. Many times the router is forced by its cables to be tethered to one
spot while the wireless antennas need to be in another spot to give optimum
signal coverage. I notice that Linksys also offers a remote antenna mount.

Lots of hobbyists. Maybe you'd like this large antenna:

I've heard that one several times here. In my case, the reflector was
enough, even though the WAP is at one end of a long house.

For a laptop, I favor a USB adapter instead of a PCMCIA card for the same

It's not done "it's the best way to do it", but because adding router
capabilities to an AP is pretty inexpensive.

Stefan,

I have 3 computers wired to a Linksys wireless router (and, I'm looking
to wire a fourth PC). Would it work to replace the router with a switch or
hub and then run an ethernet cable from the switch/hub to the wireless
router? I want to move the router closer to the deck (about 25 feet from
the current location) for stronger signal.

I'm not sure of the terminology. Am I looking for a router, switch, or
hub? And, can my cable modem connect first to a switch or hub (for
the wired PC's) and then connect to a wireless router downstream?

Thanks!
Scott

Your cable modem is likely configured to issue only one IP address. You can
put as many switches between the modem and the router as you want -- as long
as they do not request an IP address (they should not). I'm not sure why
you would want to use a switch between the modem and the WAN port of the
router -- a long ethernet cable would suffice. If you would like to add
additional devices to the LAN ports of the router (e.g. if you have more
that 4 devices), you would put the switch there.

Overall, you probably do not want to connect any computers between the modem
and the router. The cheapest solution would be to buy two long ethernet
cables and run one from the modem to the WAN port of the router and another
one back from a LAN port to a switch that is close to your wired computers.
If you do not want to buy a switch (a 4-port switch should be pretty cheap),
you could also buy a few more long ethernet cables.

If you could start from scratch, I would recommend getting a standard router
(they're more expensive than switches) and connecting it to the cable modem.
Then, get a wireless access point and run a cable to it from the router (or
connect your current router via a LAN port instead of the WAN port and turn
off DHCP). If you do not want to run a cable to it, you could also use a
wireless solution (costs more though).

Yves,

Okay, I like your suggestions about running a long ethernet cable to the wireless
router, and then a cable back to a switch...for the wired PC's.

Come to think of it, I suppose the router should come directly off the modem,
for firewall purposes.

One other basic question: The difference between a switch and a hub. Does
one of them split the bandwidth and the other doesn't?

Thanks!
Scott

As Clarence was saying, hubs repeat everything on every port (i.e. the
network ends up being no better than thinnet or wireless) while switches
know what devices are connected to each port and only send what needs to be
sent. Thus, switches allow two devices to talk to each other without
creating unnecessary noise for other devices. While hubs were OK for 10
Mbit/s ethernet, I think that the 100 Mbit/s ethernet standard only allows
for a maximum of two hubs between any two devices connected to the network
and hubs do not support the use of long cables at 100 Mbit/s. This limits
things severely and so switches are preferred. Given that just about
everything sold for ethernet these days runs at least at 100 Mbit/s, there
is no real use for hubs anymore.

Or modem to router, then a long cable to the second router. The WRT54G
(wireless) router has an option for making it a router instead of a
gateway, "The Setup Tab - Advanced Routing - Operating Mode".

Hubs repeat everything on all ports. They are dirt cheap because nobody
wants them, and they are probably all discontinued. Switches only put data
out on the port that needs it. Routers might be cheaper than switches with
rebates, because they are the high volume item. You could get a second
wireless router, and expand your coverage area.
