I have locked up my x61 several times in a row by doing a download from a fast server and nearing 20mb/s over wifi. every time it starts to level out around 20mb/s it locks up with the wifi signal still flashing.

I have limited the incoming bandwidth to 2mb/s and have avoided any crashes yet. Windows 7 pro 64

Which wireless card do you have installed?

I'm guessing the wifi card is overheating causing a crash due to instability.

It has a 4965AGN. I have an Atheros 9285 around I will replace the 4965 with soon.
I was worried I was writing too quickly to the SATA bus and crashing that.

Cards that have proven good in the X61 are the Intel 6200N and 6300N.
Only difference between them: 6200 uses 2 antenna wires, 6300 can use 3, but works just as good with the (outer) two.
You'd need an extender, since these cards are half-size: http://www.ebay.com/itm/331161237621

If you have a copy of linux laying around, try downloading with that to confirm it's a windows issue.

+1 for the 6300N. I have one in my X61s.

RBS: Do you have a link for the 6300N card?

Is it this one?

That card has a Dell number (4WOON) on it, but it's the right model, and if you have Middleton's BIOS installed: no problem.

Thanks RBS, JPOESQ and others! I just purchased the 6300N and half-card adapter.

(P.S. RBS did that Atheros AR9380 card work out better for you than me?)

My X61s has a half-size 6300N with adapter, but it's currently not being used.
My current travel-X201 (with X200s 1440x900 LED-screen) has an AR9380.
Never had a problem with either card.
Not sure yet what to put in my X220 and X230, most likely a Killer card.

Will it work in and provide more functionality in a X61 over the 6300N?

It's a matter of preference, really. Killer cards are Atheros-chipped, and if one prefers that chipset over Intel (I do) it would likely make them happier...but they still get stuck with 300 Mbps using two antennae...

Having said that, the price is insane. You can have an AR9380 for 1/3 of that amount, and 9280 for even less...

What about their visual bandwidth control:

Or their Advanced stream detect:

Haven't tested any of them so I can't say.

Having said that...on an "average" router and within standard environment, with 2 antennae involved on the laptop you're extremely unlikely to notice a difference between Killer 1202 and AR9280.

10-4! Thank you.

@E350: You seem to have expensive taste! Again!

My potential Killer would be an AC-card, but not before I get an AC-router (if ever).
