Dell WiFi cards vs Intel

Gotta love ProSupport and yeah it is pretty simple. Kind of reminds me of when I needed a replacement keyboard, no one made a fuss about the fact that I wanted to install the kb myself, in fact, they asked if they should send the tech or I'd do it myself.

 

with my belkin n750 router and 6300 i can get connected to a 450Mbps network and maximum copy speed i can get is 25-27 MBps. with my older laptop with double antena max copy speed i get over 300Mbps network is 15-17MBps.

From my experience card itself has little effect on "signal range". Biggest issue is quality of integrated antenas. Which I've tested sometime back (around 3 years ago) with few older a/b/g cards in my older hp 8530p and acer 5520. Conclusion was, even "crappiest card" in hp got better reception than "best" card in acer. Signal strenght according to backtrack was always around 30% better with any card in hp.

I've had to test my wifi card from hp in my m6600 and i was getting same results about copy speed rates and lost packet counts in comparison to current 6300 card.

 

I am a little confused...Are the antennas in the E6530 a separate part(s) from whatever WiFi card the system is originally ordered with, i.e. the antenna(s) are the same for either a Dell or Intel factory installed card, (and built into the case) as opposed to them being attached to and come with the card?

 

Yes they are the same, the card has connectors on it where you plug in the antennas. Your laptop should have three antennas, how many are plugged in depends on the capacity of the card, the 6300 takes 3 antennas, the 6200 and 1504 will take two. Each antenna amounts to one stream or 150 Mbps per antenna. When you see 3x3 in the description of a wi-fi adapter, it means three streams in and three streams out , in other words 450 Mbps both ways.

 

So all antennas in the unit are Dell OEM, and the same get plugged into whatever WiFi the unit was factory configured with, rather than you get Intel antennas with a 6300 card or Dell with the Dell card?

 

All the antenna(@ least for laptop) are more or less the same. Exactly, for one model, it only have 1 type of antenna.

I think when people refer to performance of antenna, it is more about how they are placed and the chassis design. ie a generation of XPS 15 or some samsung wifi were total crap regardless of wifi card due to their design.

 

So switching from a Dell card to a better Intel card will give the same WiFi performance as if the Intel were installed at the time the unit was factory configured?

 

Correct, the antennas should be the same.

 

Perfect...thanks to everyone for walking me through this clarification .
