{MOVED}Issue with wifi adapter on dell inspiron 7720r se

Hi,

Welcome to the community

By any chance have you tried connecting your laptop to LAN/Wired connection? Just to check if it also drops the connection. Also, try to logon to safe mode with networking. restart the computer, on Dell logo keep tapping F8. Choose safe mode with networking. Test the connectivity during safe mode login.

Let me know of the results.

Ive tryed lan connection, works even worse. In safe mode could not really do anything to spot problems.

When in safe mode with networking, will the connection work correctly?

It works, but i can not test any internet drops, because it takes time to lag, it lags randomly, when I use internet for a long time.

Hi, possible hardware issue. Can you add me as a friend and send a private message with service tag. Thank you

Hi, i've checked Event Viewer - Custim Views - Administrative Events, and i noticed the most frequent(or the only error) which occures more then 5 times a day at least. It sais following:

"Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 0x6236DD0AA145.  The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server."

I think i've solved my issue by Unchecking “Internet Protocol Version 6”. Tested online game, worked fine.

No, my problem did not solve keep getting time to time message above, during internet drops.

Try to back up files and reset the computer to factory settings by Windows 8 recovery.

For Windows 8, go to settings, click Power, then Hold down the Shift Key, while holding it down, click restart, then troubleshoot.

I 've done reset multiple couple of times (about 6), because i had issues with kaspersky antivirus. After 3rd or 4th reset i got this issue. I will try to reinstall windows completely maybe even use my previous copy of windows 7. Unfortunatelly i am not able to do it right now, because i have no time. I will do it as soon as i will have free time and report about issues if i still have them.

I understand. Just post back for any updates or if help is needed. Thanks

Hi, I re installed my windows, was not really helpful. I had an idea of replacing my wifi chip, with another one (it looks like it will fit). But i can not unscrew wlan chip from my dell. It seems like it was glued in there or something, can you give me a hint how to unscrew it please?

Hi anton27,

Please open the Owner's Manual that I have shared with you in my initial reply. Check page numbers 31,32 and 33 for complete instructions on removing and replacing the wireless card. For your reference below is the procedure to remove the wireless card:

• Disconnect the antenna cables from the connectors on the Mini-Card.
• Remove the screw that secures the Mini-Card to the system-board connector.
  
  
  
  
  
  
  
• Lift the Mini-Card out of the system-board connector.
  
  
  
  
  
  
  

Note: Please read through the pages for complete set of instructions. Also, make sure that you follow the all the safety guidelines.

Hope this helps. Reply if you have any questions, I'll be happy to assist further.
