Unique problem with intermittent wifi on alienware m17x with qualcomm killer wireless

Jump to solution

Hi, I have a alienware M17x with windows 8.1 and qualcomm killer wireless. I have a severe problem with intermittent wifi, which shows up when i use programs like skype, steam, multiplayer-games, etc.

Even though the wifi is connected, the connection will suddenly stop working sometimes, mostly when i'm using the above mentioned apps. (if i try to load a webpage during this time, the page gets stuck on "resolving host"). Weird thing is, if i disconnect and reconnect to the wifi network, the internet starts working immediately. Or i can wait a few mins and the connection gets restored automatically. This is not a problem with the network, because i've had this problem on innumerable wifi networks i've worked on, and all my other devices work just fine at the same time my laptop stops working.

Also, this problem only happens on wifi, if i use a cable connection, this never happens. (it is not even a case of the wifi signal strength, as this happens even when i'm sitting right next to wifi router, and the wifi icon in the notification area is showing full signal).

Over the last few months, i've tried various possible solutions, but none of them have solved this issue:

-Updating to windows 8.1

-Updating qualcomm network drivers

-Shutting down various applications which i thought might've been causing the issue

-Uninstalling different applications completely

-Shutting down all antivirus programs

Still after all these steps, the problem persists. It wouldn't be such a big problem, as the loss of connectivity isn't permanent, but this makes multiplayer games completely unplayable on my alienware machine. Smiley Sad

Just today i tried running the AlienAutopsy test for my Killer Wireless-N 1103 Network Adapter multiple times, and each time the "Data transfer Verification test" failed because of no connectivity (all other tests passed just fine, only this one test failed all 6 times). I thought this might be related, and gave me some hope that i might be able to zero in on the cause of this unique problem. Therefore, i am posting here. If anybody can help me, it would be very much appreciated!

+++S.O.L.U.T.I.O.N.+++

Go to Network -> Network and Sharing Center -> Change Adapter Settings -> Killer Wireless-N 1103 Network Adapter -> (right click) Properties -> and the finally UNCHECK (the f*cking) »Qualcomm Atheros Bandwidth Control«

Enjoy the rush.

Cheers

rajata,

What virus program and firewall are you using?

On wireless, can you run Network Interface and post the results back here.

See if this tweak helps...

Hit the Windows key and the x keys at the same time, device manager. Click on Network and then right click on your network adapter, left click properties, power management. Uncheck the box, allow computer to turn off this device to save power.



Go to the power options, and changed the Wireless Adapter Setting, from Maximum Power Setting to Maximum Performance.

Hi Rick, thanks for the reply!!!

Below are the results for Network interface:

There is 1 interface on the system:

Name : Wi-Fi
Description : Killer Wireless-N 1103 Network Adapter

SSID : RAJATAGA
BSSID : 00:1b:2f:df:01:54
Network type : Infrastructure

Both the tweaks you mentioned, i had already implemented a couple of months earlier when i was searching the net for solutions, but unfortunately no improvement Smiley Sad

I don't have any 3rd party av/firewall installed, just Windows defender and Windows Firewall.

rajata,

I use these Recommended Wireless Router Settings I use channel 11. There may be something in the settings that may help. I may suggest you try WPA2-PSK(TKIP)Security (Personal) I turned off my firewall in my wireless router and just use the firewall on the computer.

I have not used the Killer Wireless-N 1103 Network Adapter.

Hit the Windows key and the x keys at the same time, device manager, network adapters, right click on Killer Wireless-N 1103 Network Adapter left click properties, click on advanced. Look and see if this adapter has Antenna Diversity. It may or may not have this. If it does have Antenna Diversity, try changing it from Auto to Aux.

Did you install this adapter on this system? Did you install the operating system on this system?

Hi Rick,

thanks again for responding! i doubt it is a router issue, because i've had this problem with my laptop on all the routers (around 5) i've till now at home/office, etc.

But i changes the settings to the ones mentioned in the post, also updated by router firmware, and changed the security to WPA-PSK(TKIP).......i then switched on all the applications which usually cause the issue like steam, mmos, skype, torrent, etc., and surely, after 5 mins the problem resurfaced Smiley Happy

I checked the adapter settings, it does not have Antenna Diversity. This adapter/OS(w8) was pre-installed on my system when i ordered from alienware.

Can't help but think that this problem is due to the killer wireless adapter, and i made a mistake choosing it. My laptop is still under full warranty, but i'm not sure how/if the support guys will even be able to figure out the problem here. Smiley Sad

I Called and they got me to Update my BIOS and the Qualcomm Killer Driver individual driver, not the one that covers Lan also but only WiFi (i think) and so far its worked but ill see if it goes bad again.

Hello,

I have this exact same problem.  It primarily happens when using steam but it also affects all of my online gaming.  I have spoken with tech support over the phone and did all driver/software updates, and even adjusted my power settings all to no avail.  Next, they sent a tech to replace the wireless network adapter and that didn't fix it either.  This problem has been going on since I bought the computer last summer I'm out of ideas at this point.  Any more insight would be great.

Thanks,

Feels good to hear that i'm not the only one with this problem Smiley Happy

i'm all out of ideas here, i was beginning to think that maybe it was faulty hardware, but it seems even changing that didnt fix it for you......disconnections every now and then for 1-2min doesnt sound like that big of a problem but when it happens everytime, and specially in online gaming (which we specially buy alienware for), it starts to get very frustrating Smiley Sad

Just to add I'm also suffering this problem, alienware m17 r4, same wireless card. (win 7 though)


It seems to disconnect whenever a large amount of bandwidth is used. If I try and do a speedtest (100mb connection) it will always disconnect, likewise if trying to download files and the speed goes above 50mb.


No idea how to sort this, if anyone does please shout up!
