WiFi Adapter Suddenly Stops Working!
I've strange issue with my laptop, it stops working (showing no network), after disabling/enabling it starts working for a while and than again stops.
When I listen to the songs or watching movie, i heard some sound glitches, mouse hang too. and WiFi stops working.
its happening abruptly not necessarily when i was watching movie or listening a song. Disabling/Enabling solution works but its not a permanent solution, it's happening since i purchased, i have purchased it in August 2011.
its Dell inspiron 15R n5110, Core i5 2410 Sandy Bridge, Dell Wireless 1702 802.11b/g/n, using Windows 7 SP1.
I have tried everything to fix this problem but nothing is working and its still encountering that problem. i have also claimed the warranty and they have changed the wireless adapter but its encountering the same problem.
Kindly fix my Problem.
Regards.

There is no one size fits all fix.
Certain Intel based cards have a power management issue.
(-config wps mfp infrastructure disable) is for WPA2 clients.

Symptom(s):
The following symptoms may be seen if a Wi-Fi access point (AP) or broadband Wi-Fi router does not properly support the Power Save Polling (PSP) feature:
These symptoms may be more pronounced when on battery power.
Cause:
PSP mode is a feature that provides extended battery life for notebook computers. It 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:
Contact the AP or router vendor for updated software or firmware to correct the problem.
Alternate Solution:
An optional workaround is to 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:
Set CAM using Intel® PROSet/Wireless WiFi Connection Utility
From the Intel PROSet/Wireless WiFi Connection Utility:
Set CAM using network control panel applet (NCPA)
Put the wireless adapter into continuously aware mode using the following steps:
If the slider is already at Highest / Maximum Performance, move the slider to another setting and then back to Highest / Maximum Performance.

Hey note, he said 1702, Which is Dell branded ATHEROS, not Centrino.
He needs to read the DPC latency issue on Audio dropout for XPS15Z which identifies the wired Atheros card interrupting network flow, causing dropout.
Read -
Change power settings (network, win7 plan 55% or above)
Update Atheros driver to latest
Pg 5 of Audio Link (& fwd, ignore gigabit cnnxn notes, those are wrong)
