  • Hi Depo,

    Yes, you have the latest driver for the network adapter configured on your system. Normally an update driver is released incase there are some issues with the drivers.

  • Hi,

    I have the Alienware 18 with the Broadcom 802.11ac wifi card in it and I have a big issue.

    I'm experiencing microstutter in online games (specifically Battlefield 3 and 4) - in reading forums people said that if you FPS is good then the issue is likely the wifi card or overheating video or CPU. 

    I tested all theories and finally realized that my internal Broadcom 802.11ac is the culprit - I tested by disabling the internal card and used an external USB wifi card.  The problem was completely eliminated by using an alternate card.

    I'm assuming I have to put a warranty call in to have the Broadcom 802.11ac unit swapped out for a new one - must be a lemon.


  • I am having the same problem with the broadcom 802.11ac adapter in my alienware x51 

  • Update: I found a solution to the problem. I uninstalled the Dell drivers and while I was updating to Windows 8.1 (using a separate USB wireless adapter I had purchased) it seems that Windows 8.1 found and installed working drivers for broadcom 802.11ac adapter that came with my alienware. I have since returned the USB adapter I bought and running a ping test through the broadcom shows none of the ridiculously high packet loss or jitter that was occurring using the Dell drivers. I hope this helps.

    Please send me a private message with the computer's service tag, Name registered during the system purchase and email address so that I can check what can be done. To send a private message, click on my name and select ’Send private message’.

  • I'm having the same issue with my new Alienware 18 - specifically with Battlefield 3 (that's the only gave I've played on it).  I've read the "ac" protocol is causing some type of conflict with my AT&T U-verse router.  I have an external USB wifi card myself, I'll go grab that and try it out.  Looks like I'm waiting for either AT&T to update my router or send this massive thing back to replace the wireless nic card.  I don't see any new drivers available for the Broadcom 802.11ac wireless card I have to address this issue.  Not a happy camper...

  • Add me to the list of people with issues with the Broadcom 802.11ac... I have two identical Alienware 17s, one suffers from constant Wireless Adapter  resets. very aggravating anywhere from 3 to 10 minutes I am discoed and then moments later reconnected.

    Additionally, I have seen the major frame stutters, but I just associated that to the WLAN resetting or getting ready to.

    I have tried updating Drivers, I uninstalled the drivers and reinstalled them, I have disabled and enabled the device, I have spent at least four hours on the Dell Troubleshooting pages looking for a resolution, so far nothing has resolved the issue.

    I'm at the point I'm thinking it is the Broadcom 802.11ac Adapter

    The second Alienware 17 has worked without a single issue.


    I could use a little help on this one.





  • Also struggling with this Broadcom card in an alienware any fix yet? or should I play the warrantycard?

  • Hi, I called in to dell and had them replace the internal ac card in my system - all micro studder issues have since gone away. Note that I have the extended next day in house warranty support so it was a quick fix - if I had to ship the unit out I'd be pretty ticked... Good luck. I proved it was the internal card (even when arguing with dell technicians) based on the fax that my external USB wireless card worked flawlessly in the same games while the ac card was disabled.
