Hi, I was having a 11 mbps wireless routeur but I was thinking 1 meg sec was way to slow since I share a lot of big file between my two pc and I bought a brand new 54mbps network card (d-link extreme G)... so I bought a new router the dlink 624 54 mbps extreme G..

But to my BIG SURPRISE! now my liltle network go 1.50 !! I did not pay 100$ for only 500k/s! wtf ??! ok you guys will say its the distance but now my two pc are only like 5 meter ways from each other and separated by little wood wall. when I got to the wireless option on my client pc it say connect at 54 mbps I should at least send to 3 or 4 mbps ????

do I need to set up some thing I download both new driver for my network card and routers (but darn I got the rev A of the 624 can't upgrade to 108 megabyte !!! )

but in my router config I got this for my wireless connection do I need to boost some thing ?? or 54 mbps wireless thing its just when you got your pc at two feet beetween each other ??

TX Rate : Auto 1 2 5.5 6 9 11 12 18 24 36 48 54 (Mbps)

RTS Threshold : (range: 256~2432, default:2432)
Fragmentation : (range: 256~2346, default:2346, even number only)
DTIM interval : (range: 1~255, default:1)
Preamble Type : Short Preamble Long Preamble
SSID Broadcast : Enabled Disabled

pls help!!

THX!!

all seem normal to me even the connection said im connecting 54mbps only when I check my speed with dumeter I get around 11 - 20 mbps.... not 54..

Sorry to burst your bubble, but that is the normal speed. 54Mbs is theoretical speed.
 
so there is no really defference between 11 mbs and 54 mbps ?? since I was doing 1 mb with my 11 and now 1.5 mb with my 54... wow... darn I waste my money again DHOOO... so the 108 megabyte thing its also bullsh*t
 
So you had a system with 802.11b, and you bought a new 802.g and you get almost the same.

Well it means that either something in you environment is creating it or your Network System configuration on your computers is S*** Up.

Put the two systems 3 feet a part in same room and start working on your Network configuration.

If you can connect the two computers with Cable maybe you should start first with cable and check if you have decent transfer with Cable.

As a frame of reference I bought last weekend a $9.99 Wireless Router, using it with an old Proxim RangeLAN PCMCIA (this card goes for $5 at the Yahoo surplus stores).

Got it just in order to play around and do some experiments that are not even related to Networking. Out of the box 30' away it yields 4Mb/sec.

I have been reading that they are modifing how they test so the speed is more realistic.
But, I doubt we will see that for a while.

they really aren't lieing. The carrier truly is 54 Mbs. But its all the overhead and half-duplex and interference that drag your actualy thruput down.
 
Well the carrier is 2.4GHz.

11 or 54 Mb/sec. is the speed that the internal signal processor works.

You go somewhere that has good clean very Dry weather (i.e. as little as possible water molecules in the air). You take two units that passed rigorous Q.A and you put each on a little 50? high tower. Under such condition with a clear line of sight you will get 1500? range of decent connection.

As a second step in a similar climatic envioroment you rent a 300? long warehouse. You can partition the inside with office cubical partitions that do not reach the ceiling, and Voila you have 300? range of Wireless Indoor.

It this point you call your marketing department and give then the numbers, after all the Marketing department guys are not Geeks they are not going to ask: "How did you conducted the Tests?"

So it is 1500? outdoor. 300? indoor.

Real Life is very different.

No rule of thumb, it depends on the envioroment.

Indoor would be affected by.

Position of Antennae. Number of Walls. Makeup of Walls.

Closed Doors vs. Opened Doors. Amount of Water.

Amount of Noise from Microwave, 2.4GHz phones etc. And more.

Outdoor would be affected by..

Position of Antennae. Line of sight.

Building. Trees & Scrubs.

Water bodies. General Electrical Noise, and more.

As a result. (In a very loose terms).

You can expect 20-80' Indoor. 50-250' Outdoor.


 
I get 20-30 feet range from my wireless router. It's enough for me to sit infront of the tv at home 🙂 speed I never measured nor cared to because I know that at the very least it will match my dsl speed of 384.

@54mbps i assume..

I live in Phoenix ( thus dry air ) And can get every bit of 200ft outside of the house ( router inside ) and still pull about 11 mbps...
 
Also if you have a router that supports G and B, if you only have G cards, you should disable the part of the router that makes it look for both. That will slow it down as well. If the router is set to only look for G and not allow B at all, it runs faster. But even so I think the low - mid 20's is standard speed.
 
The signalling rate is what they are advertising. Be it 11 or 54 Mb, or even the step down numbers, 5.5, 2, or 1 Mbp on a .11b WLAN. As mentioned, it's the overhead and pure in-efficiency of CSMA/CA that results in your throughput, generally about half or less of what the radio signalling rate is. Very similar to why your numbers on 10 or 100 Mb hub are so poor. AP's are akin to wireless hubs. Add the modulation of CCK, OFDM, PBCC overhead etc..., interference, and obstructions (which cause resends) and it's easy to see why you don't really get 11 or 54 Mbps throughput on your WLAN.
 
wow thx guys , really nice reply. Now I understand why.. like you guys says its more a marketing thing. I love this forum 3 kick ass question and all was reply with professional touch.

I LOVE it. I'll be more carful now when buying wireless stuff. well maybe I dont get my real 54 mbps but its working well a little bit faster then 11 mbps.

 
It is NOT a marketing thing. It is just the way the technology works.

-edit- yeah, anandtech network forums are pretty good. We've got lots of professionals around.
 
right, no more than advertising for a 10 Mb is a marketing ploy, even though you won't transfer data at sustained 10 megabits per second. The vendors just leave the onus on the consumer to educate themselves about what their buying. Now if a twirp at Best Buy or Fry's tells you flat out you'll get 11 or 54 Mbps actual throughput, that would be dishonest. Of course nobody at either of those stores would misrepresent. snicker. From the conversations I overhear I think it's more sheer ignorance than outright lies though. A trip to one of the Electronics SuperStores is always good for a laugh or two.

Stating the ?Speed? of the device?s internal clock is a technological thing.

Stating the Distance of the Wirless Devices is a ?Marketing Ploy? it is Not done according to a published standard, and the conditions of the Test are Not Disclosed with the Ads claims..

I doubt that even the Cisco with the 100mW gets 300' in an Indoor with multiple Walls. :Q:brokenheart:😉
