VERY URGENT before closing the order in a few minutes! Wireless

Hi, I am closing my order, a Latitude D830.
It is at the moment with a wireless intel 3945 ABG. In Italy and in Argentina there are no N routers nowhere, and internet providers at the moment do not provide enough speed for more than a G.
But I have read that a N card has got better antenna, also with a G router it will have at least a bit more range. Not speed, as it will work at G. But range, yes.
My agent says that this is not so, and a Dell technician said the same. What do you know? I think that here someone told me that in his experience it was true. more range.
Anyway, i wanted a Dell 1505 draft n, for just 10 euro more than the Intel 3945 abg.
She and some friend of her (she is the Dell Agent, her friends are Dell technicians) told me that the Intel has got more performances and maybe a more sure 100% compatibility. And suggested me the 3945 (as I did not wanted to pèay 60 euro more for the 4965 draft N).
Do you agree???
DO you thing that the 4965 being a Pre N could have compatibility issues in the future with the definitive N? Does it worth 60 euro more for an ipothetical more range and just the possibility to use it in the future as a real N, if it will be compatible???

 

Stick with the cheaper options. There's no need to pay that much for the Intel N. Personally I would get the intel G because there is no need for N cards yet.

 

I'm going to agree with Adinu - stick with the Intel 3945. Intel's wireless cards are excellent quality.

It sounds like they're charging a ridiculous markup on the 4965, though. Normally I see them for $5-$10 more than the 3945, which is worth it...60 euros? Not so much.

 

Well, and i am going to agree with both!!!
So, I close the order!!!
I wil let you all know about the notebook when it comes...
i promised a review, and I know that I am not able to do it, but I'll try to do what I can.

 

If you have an N router there is.

Which is why I have the N card.

 

Well, about myself it is all done, as I already closed the order, with a intel 3945.
But can you tell me when do you enjoy the N? As in Italy no one internet provider offers enough speed to just even match the G speed...

 

If you don't share files with other computers on your network, or you don't need an increase in range, then there's no real reason to go to 802.11n. I, however, stream moves, music, and do a lot of wireless file transfers between three computers, and the increase in speed saves a lot of time and makes for smoother multimedia transfers. I also have a large house, and the increase in wireless strength means I can centrally locate my router and not have to worry about losing speed or have weak connections when I'm at the far end of my house. My old 802.11g router also didn't have gigabit ethernet connections, and my DIR-655 router does, and that's fantastic when copying large files to my media server! Wireless is nice, but when I want to move files quickly, I plug in.

 

You actually utilize gigabit?

Even in 100mbit mode, I can only utilize around 80-90% tops, I can never max it out so I don't see how gigabit ports would help.

 

If you have a PCI bus, the GigE chip will share bandwidth with other components, thus lowering the overall speed you get. However, use a PCIe bus and you get GigE speed, since the 250 MB/s isn't shared with anything. Luckily, my desktop board is a PCIe motherboard, so that's how I get the GigE speed.

When I switched from my old Linksys router to my DIR-655, the difference was night and day.

 

Just because you have a PCI-E board doesn't mean you are in the clear. A lot of PCI-E boards still put the NIC traffic through the PCI bus.

 

That is true, so it's important that buyers research the board before buying. Often, boards with dual GigE connectors have one going through the PCI bus and the other going through the PCIe bus.

WARNING! SCIENCE CONTENT!
However, boards using the PCI bus can also achieve true GigE speeds. My other desktop uses the D865PERL motherboard, and the GigE connector bypasses the PCI bus entirely and connects directly to the MCH (Memory Controller Hub) chip, which means it gets 266 MB/s to the ICH (I/O Controller Hub). So, there may be people out there that can actually get GigE speeds, and didn't even know it!

 

Kegobeer, and, well, now it is too late to change my order, but, do you think that a N card (draft n, as the Intel 4965) used with a G or even B or A router can do its part of "increasing the range" and give me more space of action?

 

A card may be more or less sensitive, but the router determines the overall range of the network. I think the only difference you might see would be several feet one way or the other.

 

As nearly perfect as my Abit IP35 Pro is, the Gigabit Ethernet is PCI
