XPS-13 wireless: Broadcom vs. Intel

I'm getting tired of the flaky behavior of the Broadcom wireless card in my XPS-13. Some have said replacing it with the Intel card resolves this. Could anyone confirm this is the correct card: www.amazon.com/.../B00STV5UKW

If not, could someone post a link to the correct one?

The intel wifi card was a huge improvement for me.  no signal issues, great performance...  i'll consider myself as a lucky XPS13 owner.

Yes, it is an improvement, but nowhere near what other devices have. A speed test of uploading/downloading the same file to the same server one time with a MacbookPRo and the XPS13 on the same network sitting next to each other, reveals that the Macbook is faster by about 2 seconds (every time).

Also the connection stability is much better with the Macbook. I can walk with both laptop around and see that the XPS13 is showing "lower bars" in the menu.

I'm not saying it is horrible, just that the XPS13 might be prone to interference more than other devices.

I also found the Intel card a huge improvement but the signal sensitivity could be better though it's still acceptable and stable.

Interesting comparison! Thanks for the details. Hopefully this improves. I don't think Dell can currently do anything about this though. First let's just hope they switch to Intel wifi, then maybe we can focus on getting better Intel driver.

I'm not so sure it's a driver problem. It might as well be the physical construction of the XPS.

Ah, such as something blocking the signal? Could be. I never thought of that. One way to test between your theory and my theory would be to know how the wireless signal is on Windows. However, I am not at all interested in installing Windows to find out.

You are right but I don't have Windows and will not be interested to install Windows too. Hopefully somebody else will do.

I found this on a Debian forum:

Known Issues

Frequent disconnections can be experienced. This may be resolved by disabling power management via:

iwconfig(8) (e.g. iwconfig wlan0 power off)

laptop-mode-tools: set WIRELESS_BATT_POWER_SAVING=0 within /etc/laptop-mode/conf.d/wireless-power.conf

It worked for me! I finnaly stopped experiencing the annoying disconnections!

I still found a problem in the solution above. The power management was going back to ON whenever the power cable was unplugged. There is a solution here: http://askubuntu.com/questions/606446/power-management-for-wireless-unable-to-turn-off-in-xubunu-15-...

I have had some serious issues with the Broadcom working properly.  I would have to uninstall/re-install the driver constantly just to get the wifi to connect.  Just bought the Intel 7265 and installed it.  Wireless performance is much better already.  From a stability standpoint, too early to tell, but I have a good feeling this will solve my issues.  Shame on Dell for putting a *** Wifi card in a high end laptop.
