Wifi Limited Access

[AryaN]

I have been facing this problem from a year but this time the problem started occurring frequently.

[I'm using Windows 7, Wifi driver is - Broadcom 4313GN 802.11b/g/n 1x1 Wi-Fi Adapter]

Problem - While using my wifi, I often encounter "No Network Access" problem along with 'Limited Access' displayed beside the wifi icon.

Spoiler for Hiden:

It randomly occurs every 10-15 min.
I tried diagnosing and troubleshooting but whenever i perform these tasks, it usually hangs my laptop while troubleshooter is  'restarting the wireless adapter'. Sometimes my wireless adapter disappears from the network panel.

To fix this, i simply restart or hibernate my laptop which fixes the problem but its only temporarily. The same occurs again after 10-15 mins.

LAN is working fine but WLAN. Also, this occurs to all wifi networks, not just mine. Its a Software problem, no any hardware issue.

ALSO, If i shake my laptop a little or just shift/move it a bit - I instantly get wifi limited access issue (Happens all the time)

I have gone through internet for like 100 times, still haven't found any solution that permanently fixes the problem.

Methods i tried -
Resetting TCP/IP
Re-installing/updating wifi driver
Changed dynamic to static ip config
Reset a heck lot of things using commands in cmd
Made another windows account
Reset the wireless router
Tried hitting my laptop's backside while raging.
Scanned for the virus, none found.
Checked manually, gone through all active services and processes. All are good. No trojan/malware whatsoever.
Checked battery settings - all good

Any suggestions?  Formatting my laptop is the last resort.

The problem seems to be at your router. Maybe the WiFi network is set on wrong channel broadcast. Navigate to router's WiFi options and if possible upload your settings.

Could also be your laptop's WiFi module being faulty and it's cheap to replace fyi.

Try with a "usb wifi" device so u can see if ur wifi card is broken.

Mine laptop have a similar problem, it disconnect alone every random time, and sometimes i need to restart the laptop
