Battery on, and wireless stops working?

Hi
I recently bought an Asus N550JK (CN341H), which has windows 8.1 and wireless card Intel dual band wireless-AC 7260. Router is a TP-Link TL WR841N.

I have the following problem, which is very annoying and strange:

Wireless works without problems, but as soon as I go on battery, the wireless stops working. The strange thing is that the problem is not limited to the laptop, but it's the router itself which stops working too. Ethernet still works, however.
If I reboot my laptop, or try diagnostic, it still doesn't work, and I canot connect to the network.

The only fix is to shut down modem and router, wait, and reboot them...this is crazy.

I tried to download the latest drivers from Intel (17.1.0), but nothing changes. I uninstalled all drivers and reinstalled the latest drivers from Asus website (17.0.5), but still the issue. I already have the latest firmware of the router.

I contacted the asus support, but they basically say to update drivers and firmware, and then basically that it can be an incompatibility issue, and I should change router...of course I will follow up.

It makes no sense to me, since I see online that many complain about this wireless card (but I haven't found anyone with the same problem I have).

Do you know something about this issue, and how can I try to fix it?
Thanks

 

Are you sure?? I have never heard of that happening. If your Ethernet connection continues to work, I can't imagine the router and/or modem retaining any fault in this.

What are your Windows power settings for the wireless adapter?

 

Hi, yes I am sure about the issue.

It seems I solved it thanks to assistance from TP-Link. I copy here what they told me to do, in case anyone else has the same problem.


When you're using battery,Power Save Polling (PSP) causes connection issues with access points or with routers
Symptom(s):
The following symptoms can happen if a Wi-Fi access point (AP) or Wi-Fi router does not support the power save polling (PSP) feature:
•Intermittent loss of Wi-Fi connection
•Inability to initiate a Wi-Fi connection
•Poor Wi-Fi connection data performance
Using battery power can cause these symptoms to be noticeable.

Cause:
PSP mode is a feature that provides extended battery life for laptop computers. The mode requires coordination between the AP or router and the Wi-Fi adapter. Intel has discovered that some APs or routers may not implement the feature correctly or completely.

Solution:
1.Manually put the Wi-Fi adapter into continuously aware mode (CAM). This disables the PSP feature. Set CAM by using one of the following methods:
•Intel PROSet/Wireless WiFi Connection Utility
•Network control panel applet (NCPA)
Note:Using this way can cause your Bluetooth device to not receive signals. Contact your computer manufacturer for more information.

2.Disable U-APSD support
Go to Control Panel >> Hardware and Sound >> Device Manager >> Network Adapters >> Intel Dual Band Wireless-AC 7260 >> right click to select the "Properties">>Advance>>Diasble U-APSD support >>Click OK button

The following is steps for setting CAM:

Set CAM using Intel PROSet/Wireless WiFi Connection Utility

From the Intel PROSet/Wireless WiFi Connection Utility:
1.Click Advanced > Adapter Settings > Advanced tab.
2.Windows 7 or 8*: Select Transmit Power, change Value to 5. Highest.
Note:If the slider is already at Highest / Maximum Performance, move the slider to another setting and then back to Highest / Maximum Performance

Set CAM using network control panel applet (NCPA)
Put the wireless adapter into continuously aware mode using the following steps:
1.Click Start > Settings > Control Panel.
2.Double-click Network Connections.
3.Right-click the wireless connection and click Properties.
4.Click Configure.
5.Click the Advanced tab.
6.Windows XP: Select the Power Management setting, uncheck Default / Auto, and move the slider to Highest / Maximum Performance.
7.Windows 7 or 8: Select Transmit Power, change Value to 5. Highest
Note:If the slider is already at Highest / Maximum Performance, move the slider to another setting and then back to Highest / Maximum Performance

 

Interesting! Thanks for the follow up. Hopefully this will indeed help other users. :thumbsup:
