Re: Wireless speed is half that of Wired
said by guppy_fish:I understand there are limitations, interference and overhead, etc. BUT a whole half of the speed disappears? That's a lot by itself and especially so considering I subscribe to 50/25 - that means 25/17 just gone - that's a lot of bandwidth that has vanished! I've never seen that before. I can understand and accept maybe 10% or even 20% but not 50%.
... so its working at what your environment is limiting it to.
There are many factors to what is your wireless speed will be, distance, channel congestion, interference from other devices.
More importantly, the environment is pretty optimal:
The computer is about 10 feet from the VZ router.
Practically no obstruction in between.
I scanned the neighborhood and picked the least crowded channel - there is only one other network that use the same channel 1.
I have no cordless phone.
All my devices are wireless N, so no b/g to slow them down.
I just don't understand.
You're thinking about this wrong - it's not that some percentage of your speed is being taken away. It's that there's a bottleneck (the WiFi connection) and increasing any other part of the chain has zero effect because of the bottleneck. It's not an overhead problem.
I agree 25Mbps is very slow for 802.11n, but that may just be the best you can do given your setup and environment. Do you have any other wireless cards available (I don't trust those tiny little plug in ones very much)?
Do you have multiple computers? If you could transfer a file between a wired and wireless computer, you'd get a good sense of what the limiting factor is.
BTW, if the computer is only 10 feet away, why not just use an ethernet cable? Or do you mean the computer is 10 feet away while your testing it?
