Speed of wireless netowork

Hi there. I have a linksys wireless g wrt 54g router.

I notice that sometimes when I am streaming videos from my pc to my ps3 i get buffering. Is this because my router is not fast enough?

Is there a way to make it faster so that I can view videos without the buffering?

I understand there is wireless N now but not sure how fast it is..

Any suggestions will be appreciated..

The G router is 54 Mbits and Wireless N is much faster. 802.11n or N is 160 Mbits or faster
But you can't get MIMO performance from your hardware. N is not possible on a wrt54g

No, I'm talking about the wireless router/device. Yes, a wireless N router would definitely help. But try to tweak your existing one carefully first
at caldwell...

i know it will not speed up my internet but i want to know about streaming local content e.g my videos from my mac to play on my ps3 without buffering..

also i must admit that the router is located near to our cordless phone...

what exaclty do you mean by multiple input output  
hey man if i tweak the speed i can move it from 54mb to over 100 mb?
802.11 N using several new technologies, one being Multiple Input Multiple Output which allows you to increase speed, this along with others get us above 54 Mbit.  This will only work if you box supports 802.11N, it can/will speed up how data can flow.  Buffering is required for anything playing over a network but this should only happen one time and only for a second or two when running on the local network.

Are you streaming laptop -> wireless -> router -> wireless -> ps3?  If so remember your going wireless twice which adds possible problems into the mix, putting one or both on wire would speed things up...

to be honest everything is wireless...my laptop is wireless as well as the ps3...nothing is wired....the only connection on the router is the connection from the internet modem...
You may want to first play around with your channels, perhaps your on 6 as well as everyone else around you... There are a lot of things which can effect wireless signal including phones, microwaves, etc...  If you can go wired anywhere that would help you out..
nama  here is the info u wanted

Thanks. According to your screenshots, it appears that there are 3 wireless 2.4GHz networks.  Two of them have an RSSI (signal-to-noise ratio) of -90.  This means that your wireless client can see two other networks (but barely).

It appears that yours has an RSSI of-35 (which means your client was physically close to your wireless AP when the screenshots were taken).

Also, there does not appear to be a significant amount of overlap between the brian and joseph networks.

I have a couple more questions for you:
When does this network performance happen?
IE: At a certain time everyday or has it always performed like this?

Also, how far away (physically) are the devices from the Wireless AP?  If the wifi signal has to
travel a long distance or through concrete (through walls or floors) then you might have an environmental issue at play.

Try streaming something from your laptop when you are physically close to the AP and see how it performs.
Additionally it looks like the test was run close to the router, you may also want to run the test near to or next to the PS3 so you can find out the interference there... Perhaps you have different interference between where your computer is located vs your PS3 location.
Before we do that, take the laptop to the same location that the test was run and try to stream something (say, from Hulu or Youtube) and let's see how it performs.
hey here is the screen shot when i ran the test close to my ps3 img2.doc
slingingshot15: Can you stream a video from say Youtube to see how to performs.
it streams alright once it is not a very big video in hd......one other question I want to ask is normally if I am watching a video online and it starts to buffer, I pause the video for a few minutes so it can load out and then I watch it without the buffering...

Can I do that when watching local content as well on the netwrok?
As for watching local vs. network network.... That depends on how you're accessing the content.

Most internet sites will stream their media (netflix, youtube, etc).  However; most content on your local lan will treated as a file across the local network.  

Some exceptions can apply.
For example, some home NAS devices have the ability to "stream" an iTunes library across the LAN. The speed of this will depend if your lan is very chatty or not while you're streaming the music.

However; if you have say an .AVI file and you're telling your media player to "open" the file then the program as a file.

If you're streaming data across the lan then there should not be a bottleneck.

Getting back to the original question, your LAN network performance. Is your Linksys AP (wrt54g) up to date in terms of the firmware?
I wish I could say yes or no, but it depends on the software program your using to stream.  All programs have a buffer size to deal with network issues such as sudden sifts of bandwidth.... Most online ones have a larger buffer size due to the internet bursting data.  I am not sure what you using on your home network but in theory it would fill up the buffer but there is a limit, after you hit that no more will be buffered until you start playing

I personally would sift you access point to Channel 6 since it doesn't seem to be used in either of your locations...

One additional test you could do is to eliminate the wireless and go wired, you can either use the access point and two wires or a cross over wire... See if its fast or if you have the same problem.  If you had the same problem it could be the software or you computer or on the PS3....

Never know it can be strange things like that...

As you can see its not a simple get a new faster router....
Also, there has some discussion regarding wireless N improving the performance.
It will help but keep in mind:  To use the 5ghz radio frequency as opposed to the 2.4ghz radio and all wireless devices/clients will need to dual-band N-capable.  Otherwise, some devices will handle the traffic differently than others on your LAN.
Thanks for the grade. Good luck.
Thanks!  If you have any further questions about this then let me know.
