it's two antenna ,you can find more Images at here

I don't think that is the issue. Because my 4.5 years old Dell was using Intel 4965agn, and it is a Draft-N. I am still able to reach 144mbps on the same router.

So, 4.5 years later BCM 4313 is still on Draft-N? And the speed is lowered?

Seems like BCM4313 is single stream only, hence max is 72Mbps

i also now ordering 8GB corsair vengence 1866MHz....hopefully to decrease my load/boot time

TQ, abang lee.can play gamelohhttp://static.lowyat.net/style_images/1/folder_post_icons/icon6.gif

How to install an Intel 5350AGN into Y580? We can't guarantee that it works right?

Check ur modem....
/my hometown house modem can only reach 54mbps as the radio only 802.11b

mine also 54mbps max,but whats the difference between 54mb and more?
my internet only 5mbps..so its well below the max speed,am i right? o.O

Someone enlighten me please,im not familiar with this..

What router you are using ?
and if you are using WEP authentication, change it to WPA2.
Since WEP only support 54Mbps.

For internet, not much difference.
For intranet, it matters..

owh,meaning it matters when you want to share files between several network?
Does playing lan included? 54mbps enough for playing lan?

Also,i notice my speed is never stable..It jumps up and down...highest i see is 52mbps while lowest is 6.5mbps.

Yup, it matters when sharing files over network.
LAN, well wireless is still fine unless your place got alot interference..

Not stable, try install inSSIDer and scan your environment, see which channel is crowded and change your channel in the router to the less crowded one.
or move your router closer to you.

linksys model (wrt54g)

Then the max speed is 54Mbps.
You need Wireless-n router and Wireless-n card in order to get more than 54Mbps
