Hi, and thanks in advance for any help you can provide.

I recently bought an ASUS N550JK from Amazon. It was new in the box. Everything works great, except the WiFi isn't very reliable. It seems like I have to be right next to the router in order for it to work. If I try to use the laptop in my room, the WiFi will work sometimes, but will constantly disconnect and get really slow. I tried running the network troubleshooter, but it doesn't find anything wrong. I've also checked that the WiFi card is connected properly, and uninstalled/reinstalled/updated the drivers. I still get the same problem. The laptop is showing about 4 bars as its signal strength, so I"m not out of range. I also have no problems with my phone, PS3, and other laptops in the same room. It's only this one that is causing me problems.

The wireless card that came with the notebook is an Intel Dual Band Wireless-AC 7260 with Bluetooth.l

Any help would be appreciated. Thanks.

The title of you post likely represents the true cause of the problem it is not just your PC is everyones that has issues.

Since you have good signal strength you hardware is likely fine.

Your problem is all your neighbors trying to use wireless just like you are. Pretty much everyone stomps all over each other and nobody get good results anymore using wireless.

What you are going to have to do is try to find some bandwidth all for yourself. Most the configuration is done on the router. You can try changing the wireless channels and maybe get lucky. On the 2.4g you only want to use 1,6,11.

This trick used to always work but there are far too many people. So now you are going to have to pretty much disable all the fancy...

This trick used to always work but there are far too many people. So now you are going to have to pretty much disable all the fancy features that give you high speed and live with a maximum of say 150m. You have to look at as slower is better than no connection.

802.11n uses 40mhz channels to get the base 150m speed which is then doubled by things like mimo to 300 or 450. You need to force the router to only use 20mhz channels. There is only 60mhz of bandwidth on 2.4g and 180mhz on 5g. So now you might find a single 20mhz block that is free rather than trying for 40mhz.

802.11ac is even worse. It wants to use 80mhz of bandwidth. This is why it can not run on 2.4g since there is only 60mhz total. There are only 2 blocks of 80mhz on 5g. The odds of you getting 4 5g channels with nobody using them is very small. Pretty much in a area with lots of other users you will not get 802.11ac to run cleanly. Unfortunately you will have other neighbors trying to run 802.11ac eating 1/2 the 5g bandwidth so even if you set yours to 20mhz you may still get interference.

There is no good solution to this problem....other to just admit WiFi is not going to be a reliable connection and likely to get worse in the future.

I've been dealing with the Intel AC 7260 Dual Band Wireless N card since February of this year, and I have seen it in Dell Latitude e5440, the e7420, and the Dell Ultrabook. Plus, Lenovo Thinbook's.....and in EVERY one of them, the driver itself is the problem. We have about 3000 users here, and probably 20% of them use one of those 5 models and each and every one of them have had a problem with intermittent connectivity, that typically lasts anywhere from 5 to 10 minutes, and then it will disconnect, and automatically reconnect. The ONLY solution that I have found was to get a copy of a legacy driver from the Intel site, the version was dated 2/20/2013 - and use that.....what sucks now is, they've pulled all of the 2013 drivers from the site! You can't get it any more.......This problem is 100% Intel.

If you have an Atheros WIFI adapter then I have a solution for you.

Atheros WIFI cards are scanning for access points, even when connected, making wifi connection unstable.
All you have to do is to disable the background scan by adding a few registry keys:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}\XXXX\Ndi\params\bkScanEnable]
"ParamDesc"="BackgroundScan On/Off"
"Base"="10"
"default"="1"
"type"="enum"
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}\XXXX\Ndi\params\bkScanEnable\enum]
"1"="On"
"0"="Off"

where XXXX —is your wifi adapter's number (mine was 0011)
After that open Device Manager, find your wifi adapter, open it's properties and set bkScanEnable = off.
