54MBps wireless going at 11MBps

[Phillip]

any suggestion how to set/force this to 54?

trendnet 802.11g router, belkin NIC and a belkin 802.11g wireless usb adaptor

the first time i set it up it did get 54 a few times, but now seems to be at 11. signal strength is 'very good'

 

[OdiN]

If it doesn't have a great enough signal to get 54Mbps then there isn't much you can do. It might not be able to find enough wireless channels to get that speed reliably.

 

[destrekor]

a 54g router will never see 54mbps. my belkin 54g router (although it is a POS and needs to be replaced) only gets about 10-11mbps, and a linksys model only gets about 16mbps.

 

[melthemoose]

it may be that there is a spurious 11b signal dragging your 11g performance...

 

[SolMiester]

Well, I actually get the full 54mbps when I have a strong signal. This will lower with leaker signals pro rata. I would check to see if you are using mixed b & g signals.

 

[ssbpgsr]

Even though the signal strength is "very good", you may still have interference on that channel. Signal to noise ratio is just as important (if not moreso), than the signal strength. Try changing channels. Try 1,6, or 11.

 

[destrekor]

you've measured the bit speeds and received 54mbps ? I dont want to not believe you, but professional reviewers have conducted tests on some of the best routers and seen they dont receive the full bandwidth.

im not sure how you are coming to the conclusion you are getting full speed, so please use SiSoft Sandra's network bandwidth benchmark. its a good test
again i dont want to doubt you, and I hope that your router truely does get that speed because then I will have to buy one lol

and melthemoose, if you were speaking to me, i have the only wifi network in the surrounding area and theres no .11b equipment in my network. the belkin just plain sucks.

As a quick aside.

If you are showing connected at 54 Mbs, then you are indeed getting 54 Mbs per second. The access point and client will adjust transmit and receive speed depending on the signal - so if you maintain 54 Mbs then that's what you are getting. Please don't expect PC review sites to have any knowledge whatsoever about networking - they just don't have a clue.

If you can connect at 54 Mbs close the the AP and then it drops down to 11 then that screams signal strenth and interferrance issues. Try the normal 1, 6, 11 channels to see what offers the best for your environment. If you can, force the AP to not run in 802.11b compatiability mode and you could see increased performance if your radio/card/signal is strong enough.

Sounds like you are using usb 1.0

USB 1.1 allows a maximum transfer rate of 12Mbits/second

Ta spidey, didnt feel like doing tests to please destreker, I get 54-48 @ home most of the time, less in the back yard 36-24. Same @ work depending on location. Thats why G band is called 54Mps. Destreker, maybe you should get a better wireless setup?

 

[SolMiester]

Oh Zstream, good spotting.

 

[destrekor]

to sol and spidey
thats really interesting, and I didn't want to accuse anybody of lieing, i apologize if it came out that way

but it just seems weird to be able to get the entire bandwidth, because well, wireless is far from perfect. And when windows reports link speed, it usually only reports the rated top speed, and then next to it percentage of bandwidth being used.
you can say review sites know less than home users, but we can throw that out the window. to claim they dont know what they are talking about, when all they do is record the stats from actual product usage, they can't fudge that up.

I might have to invest in that router, or look for some reviews.
I've never even heard of wi-fi equipment ever reaching the rated speed. They are usually tested in perfect situations, but the amount of radio inteference in the air usually prevents perfect signal transfer.

but I am glad that you are indeed getting that kind of bandwidth
and sol, I am indeed searching for a better setup. This was cheap at the time, and I still cannot afford a new router. But its the first thing that needs to be changed. lol
but if you dont know, what are you using to measure bandwidth.

 

[spidey07]

destrekor,

My main point is review sites don't do this stuff for a living and don't have a clue as to what they are actually measuring or how the technology works. That is all.

Wireless adjusts its transmit and receive speeds depending on layer 1 errors. Its built in to the protocol.

there are many here in this forum that design and test wireless chipsets, design 1000+ access point wireless networks, etc. So the good thing about this forum is there are a fair amount of "pros" here.

then my belkin really needs to die office space style then lol

you'd be surprised at just how much noise is in the 802.11b/g spectrum.

try channels 1, 6, 11.

 

[destrekor]

different channels will increase performance that much?
im running on channel 11 now, will try 1 and 6 tomorrow

What usb are you using?

 

[destrekor]

no usb for me
i've got a 54g pci linksys card and a 54g belkin router

 

[nweaver]

It's amazing when you run kismet or netstumbler in an area...I can see 24+ AP's on the 2.4 Ghz spectrum sitting here at my desk...I see 4 (and that's with the isolation chamber door open) on 5 Ghz....I love A band.

 

[spidey07]

yep, we're deploying dual mode wireless for this very reason. there's just so much stuff in the 2.4 spectrum.

I have a belkin 7230-4 wireless router and used the Belkin USB wireless. I could never get a Cnet test that would ever run more than 1400 . Most of the time it would be arround 1000 . The wireless bandwidth network connection would show 50Mbps.
I found that the USB required USB 2.0. I then replaced the Wireless USB with a PCI wireless card and now the Cnet tests consistantly run greater than 3500.
Is your USB 2.0?
