Re: How Much Speed Loss Due to Wireless Overhead?
I really don't see how you can have noticed this JUST because of having gotten "Fast DSL". Most DSL packages I've seen cap out at around 3 Mbps down. A good 802.11b setup will run 3-4 Mbps with good signal.
You don't give much details about your setup, hard to say beyond that. 11b or g? Makers? The better products show little or no speed change with using 128-bit WEP. The crap products, well.... |

| My DSL package isn't capped, and with my lines and distance from the CO I can get about 4 Mbps down straight from the modem to the laptop. Via the wireless network without WEP enabled I get around 3.7 Mbps down, with WEP enabled I get between 2.7 and 3.2 Mbps. My main question is this: Compared to a wired network, about what percent of overhead loss will the average 802.11b show? |

| Well what you can do is download a program like qcheck and run it on 2 computers on your network. Do a test through your wired switch first, and then over the WLAN. On my network I have found net throughput on a 100Mbps switch to be around 90Mbps or so (10%), and on an 802.11b WLAN net throughput is around 4Mbps unencrypted, and on a .11g WLAN, 18 or 19Mbps unencrypted. So if you do the math for the 11Mbps you see about 36% and for 802.11g 33%. These are just what I have found in my network and seem to be about what I have read for others. WEP does provide overhead, again, just do some testing and see for yourself. |

| I am using a linksys befwlls4 v2. that is a 11b set up. 4 computer 2 xboxes connected to the router. Two of the computers are connected wirelessly.
My connection is SBC dsl. My line is rated at 6016 Kbps (downstream)608 Kbps (upstream) I test consistently test at 5000/500 give or take on the wired computers.
ON the wireless conntection the numbers are more like 3500/500 give or take a few. |
