Default N vs G Range with G devices

Thanks in advance for any help.

I'm currently using an 802.11g wireless access point. The devices in
my house that connect to it are all 802.11g. I am having some signal
issues in parts of the house.

I know I won't get faster speeds, but is there any advantage to using
an 802.11n device as the access point in terms of range, if all the
devices are 802.11g?

Thanks again

No, I don't think an N router operating in G mode will offer any
advantage. In fact, may reduce your current options if it doesn't
have removable antennas.

Instead, why don't you go ahead and give us a description of your
router model and the various devices that connect to it. Describe your
house layout and where the problems are.

There is almost certainly a good solution using G, perhaps with a
higher gain antenna (or reflector) perhaps adding a second AP
connected by cable or powerline networking to your existing router.

Thanks very much for the help.

I have an older, brick, plaster-walled house. There are two stories
and a finished basement. I have a Linksys BEFSR81 router in a room on
the second floor into which the Comcast cable comes and my main
desktop PC lives. This room is wired to 2 bedrooms on the second
floor, one room on the first floor, and the main living area in the
basement. In one of the bedrooms on the second floor, I have a Linksys
WAP54G with the 7dB antennae. I put the WAP in a bedroom because the
room with the cable has a ton of electronics. The room on the first
floor has not been good for the WAP because it's built on a concrete
slab and really is apart from the rest of the house. That room has the
family computer, wired to the BEFSR81.

I have 2 daughters in college who use their laptops when they are home
for breaks and the summer. They work in a room on the first floor that
gets good, but not great, signal. I'd like to get better signal in
that room.

On the first floor, just below the WAP, I have a TiVo and a music
device (SquuezeBox) that essentially plays music from the internet. I
don't use it to connect to a music server in the house. I also have an
iPod Touch and a cellphone with wifi that I like to roam with. We have
an outside porch and I get no signal there. In addition to better
signal for the kids' laptops, I'd love to be able to get signal on the
porch.

I have tried the Linksys range expander. It worked well for signal to
the laptops (but not the outside porch), but kept disconnecting from
the WAP. I kept having to reset it.

Thanks very much for any suggestions.

Definitely not. Indeed, as 802.11n APs has a natural coverage
advantage (due to technology) vendors are building them with an
average output power lower than traditionally found 802.11g AP (not a
rule, but it is for sure a tendency). So replacing your G AP with N AP
will - very likely - reduce your 802.11g devices coverage range.

You are absolutely correct. I tried it, just for kicks. My results
were worse with the N router and I returned to my all-G setup.

Thanks for the response.

OK. That's great that you have ethernet everywhere already. I'm not
totally clear on the setup, but close enough, I think, to offer
suggestions and comments:

First, consider the 7dbi omni antenna on your existing WAP. It
radiates in a disc for 360 around the antenna. Because it's 7 dbi,
it's actually a narrower disc than the doughnut shape of a stock 2dbi
omni.
So, ff you have it pointed up (normal) on the second floor,then
anything above or below it is in the dead zone. Or weak zone.
Tilting it down so that the side of it points to your most distant
area (porch) may help. Putting a reflector on it should help even
more:

http://users.picknowl.com.au/~gloaming_agnet/ant2.html
http://www.freeantennas.com/projects...te2/index.html

Try it with your old stock antenna as well as the 7 dbi one to see
which works better with the reflector.

But I wonder if upstairs is where you want the WAP. Is there any
client upstairs that connects wirelessly? If not, more it downstairs
and you can even try a reflector there towards the porch. Anything
in the room with the AP will probably work no matter what you do with
the antenna pointing, so you are looking for improving the most
distant point that needs to connect to the router.

If this doesn't work or you need to keep that WAP upstairs for some
reason or another, add on another inexpensive wireless G Access Point
or router to your ethernet in a strategic location downstairs - closer
to the porch. Because you have brick construction, it's going to have
to be pretty close to the porch to work, but you'll see. Play around a
bit. The reflector may allow you to place it a little further if you
point towards the porch.

Location in the room is important. Higher is often better for distance
to other rooms, as there are less things in the way.

I mentioned getting a wireless router because it can also act as an AP
and has the advantage of acting as a switch and allowing you to
connect 3 more items to the back, thus multiplying one ethernet
cable. The ethernet from your main router connects to one of the LAN
ports, not the WAN on the additional router-as-AP.

To find a decent router, just go to Newegg.com and start with the
cheapest until you find one with good ratings by a lot of people. Or
just get a Linksys since you already are familiar with the interface.
The WRT54GL (L important) has several advantages over the plain
WRT54G, so get that if you are willing to pay $60. http://tinyurl.com/3q8e3u

Come back with setup questions or whatever else here.

Default Re: N vs G Range with G devices

Steve,

Thank you very, very much for the detailed information.

I do have the 7db omni antennae on the WAP54G. In addition, I have the
do-it-yourself "WindSurfer" parabolic reflectors on the antennae. I
have done some very limited testing and am pretty convinced that the
reflectors offer a small, but real, improvement.

The reason the WAP is on the second floor is that the only wired room
on the first floor is the awful (for signal) built-on-a-slab room.
It's just not a good place for the WAP. (The outside porch to which I
want to get signal is just outside that room.)

I have set something up that now gets very good signal to the porch.

I resurrected the Linksys Range Expander and placed it on the first
floor, at the opposite end of the wired-room-with-no-signal. It is
behaving well and getting great signal to the laptops.

In the first floor room next to the porch, I added a Netgear wireless
router configured as a repeater of the Linksys WAP54G. It's giving me
great signal on the porch.

But ... I'm more the "tweak it until it's as good as possible" rather
than "don't fix what ain't broken" kind of guy. And I don't mind
spending a few more dollars.

So ... would I be better off using the WRT54GL in place of both the
WAP54G and the Netgear? Or replace the Netgear with another WAP54G
configured as a repeater (since they'd both then be Linksys)?

I don't need the extra ethernet ports of a router in any location. Is
a router configured as a WAP better than a dedicated WAP? It seems
counter-intuitive to me.

Finally ... it seems the best configuration given the constraints of
my house are ... the WAP in a middle room on the second floor, a
repeater/range expander at one end of the first floor, and a repeater
at the other end of the first floor (in the "dead" room). Which
device(s) do you recommend for the 3 locations? Three WRT54GL's, one
configured as a WAP and the others as repeaters?

Thanks a million.

I have seen a real improvement over stock antenna. A 2dbi omni with a
windsurfer works better than a 7 dbi omni on a Linksys I have setup.
When I put the windsurfer on the 7 dbi, it helps a bit too, but the
2dbi is better for the reflector, I think. I only used one antenna
and disconnected the other when using the reflector.

The slab is bad because you need the signal to get thru below it? I
don't see how it would hurt if not trying to pass through. For side
to side it should be fine. Only you really understand the layout, but
it seems a waste to have the WAP upstairs. Again, tilting the antenna
side towards intended hot spot helps.

These range expanders have reliability issues as you saw before.
Also, can you get it to do WPA (which you should be using) security?
From experience and advice from experts here, I'd avoid them, but if I
had one, what the heck. It does seem to work.

Actually as a repeater, or as a wired AP? Again, wire it if at all
possible. Really.

Not better or worse by nature, just cheaper and more possibilities
when setting things up or expanding. And routers that take
replacement firmware can operate as a router/repeater/ AP/ Wireless
Client. The wireless client mode is particularly useful not only as
a client but with a wireless client feeding an AP, you can make
superior two-radio repeater.

So you have a good working configuration ! Very good.

Again, it's hard to second guess you from here, but IF I was starting
from scratch, I'd probably do it this way:

Router/WAP in both ends of first floor (different channels) connected
to main router by wire. Forget wireless upstairs. Forget simple
repeaters.

For the room without wiring, I'd either run powerline networking
(Netgear XE103 is fast and reliable) from the router to it that room
and then go into the WAP from there, or...

Instead of using powerline you could make up that two radio repeater
using one device in client mode and another as AP connected by a short
ethernet cable to each other. You can optimally position the client
to see the nearest AP and even use a directional on it (reflector or
panel antenna). The AP would probably have just it's stock omni for
best coverage in the local area.

Your Linksys WAP or Netgear router might take DD-WRT and could be the
client bridge side of the "two radio repeater". Check here:
http://tinyurl.com/2a6y96 Find links from there to see all the great
setup advice on their wiki. Ask here for advice on making a repeater
from two wireless devices.

>Which device(s) do you recommend for the 3 locations? Three WRT54GL's, one
> configured as a WAP and the others as repeaters?


Don't particularly recommend Linksys (not bad choice though) and
nothing in simple repeater mode. Again, just talking for fun (you
have it working !), if best range is your priority, then the Buffalo
Whr-HP-G54 is probably the winner for under $100. They are no longer
legally sold in US, but find one on Ebay. Used to be $60, but
scarcity raised the prices. It beats out the Linksys L, and also
takes DD-WRT.

It's cheaper little brother, the Buffalo WHR-G54S is still perhaps
better than the Linksys L and close to the Buffalo HP (high power)
once you install DD-WRT and raise the power output a bit. Buy on Ebay
also.

Besides the Linksys L, the ASUS WL500G line has USB ports, gets great
reviews and takes DD-WRT. Check at Newegg.com

As you can see, I wouldn't buy anything that didn't take DD-WRT. The
Linksys do too, of course.

But, you already have a bunch of gear and you have at least one
solution already. All good.

Glad to be helpful, I've benefitted a lot here and elsewhere myself.

Default Re: N vs G Range with G devices

OK. Looks like the Linksys range extender will do WPA when using with
WRT54G. From a Newegg customer review:

WPA and the WRE54G, May 27, 2008
By S. Mcneill (Northern Virgina) - See all my reviews
OK this is how I setup the Range Expander:

1. Connected my laptop directly to my Linksys WRT54G router via CAT5.
2. Plugged in the WRE54G extender into the wall and hit the reset
button.
3. Log into the WRT54G router, 192.168.1.1, and set wireless security
to "disable".
4. Unplugged the WRE54G extender from the wall.
5. Connected the WRE54G extender to the WRT54G router via CAT5.
6. Plugged the WRE54G extender into the wall.
7. Hit the Auto Configuration button on the WRE54G extender; should
get two blue lights.
8. Log into the WRE54G extender, 192.168.1.240, (password: admin).
9. From the WRE54G configuration menu select "Edit Security Settings".
10. Select "pre-shared WPA".
11. Create a WPA key; then highlight and copy. Change the group
renewal key to 3600.
12. Hit save settings. Should get settings saved reboot required in
your browser.
13. Log into the WRT54G router and select wireless security and change
the security settings to WPA, paste the WPA key you created in the
extender into the router field. Ensure the group renewal key is set to
3600 and save settings.
14. Should have two blue lights on the extender. Unplug and move to
the desired final location.

Why does one antenna work better than two? If you remove one, does it
matter which one?

No, the slab isn't bad in and of itself. It's bad because the room
must have been added, at some point, to what was the ouside of the
house. The walls of the room are more like exterior than interior
walls. I've tried it and the signal doesn't really get outside the
room to the rest of the interior of the house - but does do well
enough on the porch just external to that room.

I plan to get rid of the range expander as soon as I get my Provantage
order (see below).

>Actually as a repeater, or as a wired AP? Again, wire it if at all
>possible. Really.


Sorry ... yes, as a second wired AP. I put the main WAP on the second
floor on channel 11 and the Netgear (for now) on channel 1. The only
function of the second WAP is to get signal to the porch, which it
does well. Because of the physical boundaries of the room and the wide
separation of channels, I think I'm OK with 2 wireless networks.
Although I'm going to ask about that in a few paragraphs.

Not an option ... the "slab room" is the only wired room on the first
floor. My wife will kill me I mention wiring another. One WAP has to
be upstairs.

I tried it and it didn't work well - the speed was awful and I blamed
the old wiring in the house.

I've spent some time the past couple of days reading the DD-WRT wiki
and plan to flash the firmware of a WRT54GL (see below).

OK ... I ordered 2 WRT54GL's from Provantage. I'm going to replace
both the WAP54G and the Netgear WPN824 with them. I love Newegg, but
have had great experience with Provantage as well. They also have a
distribution site in Harrisburg, PA, about 10 miles from me. I get
stuff the next day when I pay ground shipping.

I ordered Linksys because I'm comfortable with the interface and I'm
confused enough already.

So, I will have 2 WRT54GL's. I plan to flash one ar both with DD-WRT.
I have 4 7dB antennae that I can use (or not). One WRT54GL *has* to go
in a second floor room wired to a Linksys BEFSR81 router. The second,
I believe, has to go in the only room on the first floor wired to that
same router, the "slab room" next to the porch. Ideally, I'd like to
have only one wireless network (so I don't have to switch when I go
out on the porch), but can live just fine with 2.

What do you suggest for the two WRT54GL's relative to (1) flashing
with DD-WRT, (2) type/number of antennae, (3) relationship to each
other, ie, none (2 networks) or a repeater. I plan to eliminate the
range expander from the equation.

Once again, thank you very, very much for your time and patience.

Great. You are really on the ball. I'm not much ahead of you!

It seems kind of odd to be dumping what you've got, but it's a good
plan otherwise. Just sell them on ebay.

We are traveling for a couple of days. I'll give you a long answer
when I can.

Did you really try powerline networking with 103 s? or some other
system? There are various standards and they are not equal.

Actually, I tried the Linksys version. The utility it came with
indicated I was getting speeds of 9 Mbps, which seemed awfully slow.

OK. I'm back. Concerning the powerline networking, as I said, there
are various standards and some are more robust than others, it
seems.

You say the linksys was only 9Mbps, which makes me think it's an older
system. Still, how much speed do you need for internet? Apart from
streaming/transferring video around the house, 9 Mbps should be good
enough.

Netgear has an older, cheaper XE102 that is only 14 Mbps, but
reliable. I picked up a pair of them for a bit over $25 each on
Amazon. http://tinyurl.com/4d27pd
Here's the pair: http://tinyurl.com/55lhmm I bought them used from
netdirectbargains seller.


You may still want to consider this as a solution for downstairs
instead of repeating. Avoid the high speed Netgear, I heard, and go
with the XE102 for internet or XE103 if you need medium speed. Of
course there are other brands. Just suggesting what I know.

Thank you very, very much for all the help. You've been extremely
kind.

I do, in fact, want pretty good speeds because I am primarily using
wireless for media - music streaming and TiVo transfers. The Linksys
Powerline was "rated" at 100 Mbps and didn't really work well for me.
I don't think I need it though, as I have come up with what appears to
work great. I only set it up tonight, so I'll wait and see.

I got my two Linksys WRT54GL's and flashed each with DD-WRT. I set the
power of each to 80 and put one on the second and one on the first
floors. I set the SSID of each the same, but put one on channel 11 and
the other on channel 1. (This is how it was described in the "Roaming"
section of the DD-WRT FAQ to move from one are to another without
changing networks. I think.)

Anyway ... so far, so good.

One remaining peculiarosity ... the short antennae that came in the
box give better signal than the 7 dB antennae I have and I get better
signal when I don't use the WindSurfers.

Thanks again for everything.

OK. I had already started to answer your long one before, but now I
see you are getting it set up. Anyway, here' my answers, disregard if
inapplicable:

Once you go directional, whether reflector or panel antenna, I don't
think two help, so I prefer to reduce clutter. I kept the right one
(looking at the front). DD-WRT has option to turn antennas off, I
forget about the native linksys firmware.

But you used the Linksys..xxx. They aren't all the same, several
different speeds and standards. Somehow I think your wiring is not so
bad.

Consider trying powerline again, with Netgear XE102 or XE103 pairs.
Unless you think you are gonna stream HD video, that is. If doing
video, then find a recommended brand that uses the better standard- no
advice, but I think it's there. The Hi speed standard Netgear chose
is said to be problematic. But the 85 and 14 mbps they use seem
solid.

I've bought from them and been happy too. The Linksys should be good.
I'd keep the WAP as well - did you figure out if it takes DD-WRT
also?

DD-WRT is very similar to Linksys interface, just way more buttons.
Most of it you can ignore.
As an aside, they say the Tomato interface is very nice, less
powerful, but enough for most users. You may want to look at that
one.

I'd flash em both for consistency. As for placement, etc, it depends
on if you do want to check out powerline again or not. Either case,
you put one in the slab room. If you use powerline, then the other
router or AP can be optimally placed to fill in the rest downstairs -
and you decide if you still need a third one upstairs. No repeating
needed.

If no powerline, then make a two-radio repeater, I suppose. Run one of
the DD-WRT boxes as a client with a reflector towards upstairs AP and
run any other router or the WAP cabled to it with omnis. Two box
repeater allows you to optimize the antenna and placement for each
side of the link - point-to-point on the client side and point-to-
multi on the AP side.

Use a single reflector or small panel antenna for the upstairs-
downstairs link (if no powerline). Might use a reflector or panel for
the concrete room towards the porch and also to keep interference with
other downstairs network down.
Probably want to use omni for the main downstairs AP if it's
relatively centered in it's coverage area.

When using straight omnis (no reflector), might as well use two stock
ones if close to target area or two 7 dbi if more coverage needed.

I would keep everything on the same subnet, the same network. The
router upstairs handing out the addresses in all cases. What I don't
know is if you can keep the same channel downstairs and have them
overlap for roaming or if need to run different channels. Don't
know. Maybe somebody else will jump in.

But if you must still do the upstairs-downstairs link, then that
should be on a different channel than the downstairs broad coverage.

Hope that helps. It sounds like you are into it - you can play around
with antenna placement and stuff.

Cheers,
Steve

I still might be checking into it, not dismissing due to one try with
one brand. Netgear is not the one, though, not above 85.

Sure you've got the pointing correct?

If you need reach and the windsurfers don't do it, get an indoor
panel. More money, but sounds like you have some budget.
