Alright, my Dell Inspiron 13z has an 54Mbps WIFI card and it supports N, G and B, but what's the difference between them?

Also my Router (SpeedTouch 780) only supports B and G. I can't watch HD movies through my network or Youtube, what's the cause of that
?

Thanks in advance

If it's a 54mbps Wi-Fi card, it will only be B or G. N is a helluvalot more faster than 54mbps.


802.11B has a maximum theoretical bandwidth of 11mbits/sec
802.11G has a maximum theoretical bandwidth of 54mbits/sec
802.11N has a maximum theoretical bandwidth of 300mbits/sec.

The actual (practical) throughput is realistically maybe 2mbits/sec for B, 15mbits/sec for G, and depending on hardware, ~100mbits/sec for N. These are *really* rough numbers since actual throughput depends very heavily on hardware.

----

The bandwidth requirements for streaming HD media pretty much require that you have 802.11n in-place. 802.11G's practical throughput is borderline for streaming HD... Just the way things are...

Alright, another question. If I get a Linksys WRT120N (270Mbps max.) will 1080p on youtube or in my network be smoother than with my SpeedTouch 780 (54Mbps max.)?

What is your download speed? Post a speedtest.net result.

Pointless to upgrade anything if your download speeds won't hack it...

For YouTube.... what IGP do you have? Did you install Flash 10.1 Beta 3 with hardware acceleration?

To stream 1080P from youtube your internet connect needs to be at lease
6Mbps or you'll have to way for it to buffer many times. The SpeedTouch 54Mpbs should be fine. My Linksys 54 Mbps runs just fine with WPA and full signal.

These are my results on my Dell 1397 WIFI card

My GPU is a G105M, AFAIK I've got the latest drivers and flash player, it does say Hardware accelleration in YouTube. And when I play an MKV file from my HDD, it's just fluently.

Sometimes my network speeds reach 2Mbps and sometimes it reaches 48Mbps, it's really choppy when watching 1080p or even 720p
.

Would it be better if I got myself a cheap Intel WIFI 5100 mini-PCI-e card to replace my Dell 1397?

Thanks for the input guys

The question first is why does it drop.

You don't want to buy another device and have the same problems.

Is there a microwave or a cordless in between your computer and the wireless router?

I've practically tried everything, I'm sitting 1m from the router ATM
And according to other people you'll need N speeds to watch 1080p content.

Oh, my internet is 54Mbps right now btw and it's still choppy.

I think know what your problem could be. I see you have SU7300 @ 1.3GHz.
When you go to youtube, open task manager and see if your cpu is at 100% when you try to watch a movie.

The OP did say that playing a movie from hard-drive is not an issue - so CPU is not likely the culprit.

I'm still suspecting the combination of wireless-G and borderline internet speeds...

First off youtube HD content is not Real HD.

Second, You do not need Wireless N to watch Youtube HD content.

REAL 1080p content will require a good amount bandwidth.

the test you need to do:

take your laptop over to your router.
Turn off your wireless cards.
connect it via hardwire.
Play Youtube HD video.
If this works fine, Try playing a different HD video.

This will isolate the problem to either:
a) your laptop
b) connection between the router and your laptop

Is it pausing with a circle in the middle of the movie or playing and jumping?

If its pause with a circle is the connect.

If its playing and jumping then its our CPU.

A single core 1.3 GHZ CPU with no H/T will most likely not be able to play youtube in HD because flash is a CPU hog.

I also think G speeds are too low

Actually it's a dual core @ 1,3GHz and the G105M (OC'ed 9300M GT @ 40nm) is doing the decoding, besides MKV files run really fluently on my laptop (1080p). CPU usage is 57% ATM.

Sorry my bad.
MKV files are easier on the system then flash. I have my system under clocked @ 1.2 Ghz and my HD2 movie play fine CPU @ 50%.

Youtube at HD 1080p with Flash 10.0 and playing CPU @ 100%.

Youtube at HD 1080p with Flash 10.1 and playing CPU @ 40%.

If your play youtube HD 1080p and it jumping its your CPU, if it pauses and you get a circle in the middle of your screen then its your connect.

Which one is it??????
