How fast is Wireless?

.11b = 11Mbps
.11g = 54Mbps

Comparing this to a wired setup where a router is 10/100. 10 = 10Mpbs and 100 = 100Mpbs correct? So the .11g would be roughly half of the throughput speed as a wired 100Mpbs connection?

If I convert the 54Mpbs in KBps I come up with ~6912 KBps.

However, when I transfer between my two computers on my .g network FlashFXP is averaging around 850-900KBps or ~6.64Mpbs.

Am I missing something here? Because this seems AWFULLY slow. According to my DLink Diagnostic info:

Signal Strength is- 88%
Link Quality is- 100%
Tx- going between 54Mpbs and 48Mbps depending on where I'm at in the house.

Any clarification would be great.

Thanks!

Correct - note that these are the *max* transfer rates.

In theory, an 802.11g connection is roughly half the throughput of a 100Mbps link, but in reality it's very unlikely to see a wireless setup with throughput that high.

If I convert the 54Mpbs in KBps I come up with ~6912 KBps.
I get 6975KBps: 54Mbps * 1000 = 54,000Kbps / 8 = 6975KBps

However, when I transfer between my two computers on my .g network FlashFXP is averaging around 850-900KBps or ~6.64Mpbs.

Unfortunately, a wireless connection will rarely (if ever) reach its' rated peak speed. Someone else here could probably go into more detail on this, but factors such as interference, channel crowding, obstructions, and so on will reduce the average throughput of the connection. :(

According to my DLink Diagnostic info:

Signal Strength is- 88%
Link Quality is- 100%
Tx- going between 54Mpbs and 48Mbps depending on where I'm at in the house.
Hmm... I'm not sure why the diagnostic program is telling you that it's running at 48-54Mbps. Here's a great (free!) program to determine what type of throughput you are actually getting between any two points on a LAN. :thumbsup:

Thanks!

But I am still getting slower speeds then I "SHOULD" be getting. Or at least I think. According to that website: Typical 802.11g at 60? = 15Mb/sec = 1920KBps. I average about 1100-1200KBps even when my laptop is right next to the router FTPing into my XBOX which is hardwired into the router.

I'd be thrilled if I could get around 1500KBps...all I'm trying to do is stream DVD .vob files between my computers or between my computer and Xbox.

Also- Since all my cards and the router are DLink I activated the "Super G" mode which should bump speeds up to 108MBps (of course that isn't the "real" speed). But I see no change in transfer speeds from changing from the 54mpbs and the 108mpbs.

Hmm...

I know very little about X-Boxes so I do not know how the TCP/IP is optimized and the efficiency of the ftp.

If you have a second computers that is Wired you can download and install (as mentioned above) Qcheck and study the problem, and evaluate the situation between a Wired and a Wireless Computer.

Click on Qcheck Download.

You have to give some personal info, but this Application really worth it.

Down load the Main program and a copy of the stand alone End Point.

Install the Master program on one computer (Main computer, or serve). Install the End point Client on all other computers on the Network.

I have installation with the D-Link and it works within the expected limits.

However, if f none of this help you might be one of many that got a poor QA Wireless Hardware and you might try to take it with the Brand Support.

Yeah, I'll hook up one of my computers to the router and go from there.

Thanks!

What will you be using it for? If this is for broadband internet access, wireless is faster than the typical 3Meg cable or DSL access.

No, using it for streaming DVDs
