Region : Austria

Model : TL-WR841N

Hardware Version : V8.4

Firmware Version : 3.13.33 Build 130506 Rel.48660n

ISP : Linz AG


Hello!

I have a little problem with my TL-WR841N. Almost every time i try to connect my laptop (Lenovo Ideapad U430 touch with Intel Wireless-N 7260 chip - latest driver) with the WLAN the wireless network breaks down for every device in it. The connection works for a few seconds on the laptop before breaking down. I had a look at the traffic and found out that after a couple seconds the router keeps sending ARP requests which my laptop does receive and answer, but the router keeps sending ARP requests for this device. Already tried adding the laptop the the ARP table, but that didn´t fix the problem. Any suggestions? I heard a couple people have problems connecting the laptop wirelessly with networks. Wired connection works absolutely fine and also keeps working when the WLAN breaks down. Status LEDs in the front remain in normal status (WLAN status led blinking, System LED blinking aswell).

Thanks in advance!

Cheers,

DoktorMetal

just to test try
Wireless Settings
Mode: BG Mixed
Channel Width: 20 MHZ


Ok trying that. Had it in BGN Mixed mode until now. Currently works, but there also were periods of time were it kept working with bgn mixed mode for a while. I will return if the error keeps occurring.

Still - thanks for the fast answer.

After a few days of testing I think it´s safe to say that solved the problem!
Thanks!

Same problem. My company just issued new Lenovo Laptops with the Intel 7260 wireless chipset. Same thing was happening to a few of us with TP-Link TL-WR841 routers.
Turns out that this is an issue with running the laptop in battery mode.

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

Kudos to your thread.
Looks like quite complicated. Fortunately, I am NOT using a laptop with Intel 7260 wireless chipset.
