Dell Laptop Wireless Card Upgrade?

My Dell XPS laptop has a defective wireless card. OEM was Intel Centrino 6320. I believe it was replaced under Dell warranty with an Intel Centrino 6205 card. My research shows both cards were problematic with continuous losing the WAN/LAN connection. I finally pulled the card and installed a broadcom card from another Dell laptop. Intel has discontinued the 6205 I found out. How do I determine what card would be newer and an improvement over the 6320 or the 6205? It is a mini half size card, PCI-E.
Thanks

 

Which XPS do you have?

If you want hardware help, people reading the thread need to know exactly what Dell XPS laptop you own.

 

XPS 14Z L412Z

You sure it was 6320 and not 6230 ?
based on drivers that Dell offers for the original, I think you have the digits reversed.

If it was 6230, this is the card that was in it

Yes 6230 was original card. I was at work and guessing card number. I discovered incorrect card when trying to restore lappy back to original Win 7 from screwed up Win 10 upgrade. But anyway, it seems a lot of people were having difficulties with frequent disconnects from the internet with OEM card. I suspect this laptop was no different as the card installed was a Centrino 6205 with a Dell part sticker on it. This card also suffered the same issues. Intel could not resolve the issue for many consumers, and ended up discontinuing the cards. I borrowed another card from another older Dell laptop that works just fine, but I want to put a newer card in this laptop and put the other one back in service.
But the bottom line is I need a newer compatible card to put into this XPS 14Z machine.

 

If the other (Broadcom) card works just fine in that machine it sounds like you could save time by just buying a new one of those cards.

 

I am looking for a card that would be an upgrade to the original, not a step (or 3) backwards.

 

So the current card you are using doesn't perform well, and with visible symptoms to show that?
In that case yes, search for something better and I am sure Dell Support will make some suggestions based on that system.

 

The Centrino 6230 card was a dual-band with Bluetooth which, BTW, probably means it was faster than your internet connection unless you are paying for a premium service. As an aside; too, the built-in antennae are almost always far superior to the ones included in any USB device.
