I have a small but frustrating problem.

 

The wifi signals on my Dell Latitude D630 laptop completely diminish whenever it's not in the same room as my modem.  I don't have this problem with all of my other laptops and tablets, just this one.  I recently replaced the motherboard cause of a GPU issue. But what could be the problem with the wi-fi? Does it need a new network card?

Hello,

Right click your Wireless Adapter in Device Manager. Select Propterties and under the Details tab select Hardware IDs in the dropdown box. Copy and post the first line in your next post. If it's an intel wireless card, the drivers can get wonky. The updated driver may help.

Device Manager shows that I have two connections under Network Adapters; here's the IDs for both of them:

PCI\VEN_8086&DEV_1049&SUBSYS_02321028&REV_03

 

PCI\VEN_8086&DEV_4222&SUBSYS_10208086&REV_02

The first is your NIC and the second is your wireless. Sorry, I forgot to ask what your OS is and is it 32bit or 64bit.

Go here for the latest driver. The larger download includes the intel wireless software which I would recommend. Wireless_15.3.1_s64.exe

 

Version: 15.3.1 (Previously released)
Date: 11/15/2012
Size: 77.23 MB
Language: English
 
I would create a restore point first and if you have not done so yet create a System Repair Disk.

I installed the driver but it's still having the issue.  The closer it is to the modem (literally) the higher the wi-fi signal; but I step outside the room, the Wi-Fi signals drop lower or get a red x over the bars.

Your wireless card may be going bad. You can try changing the wireless channel on your router to see if that improves the signal. If that does not help you can get a USB wireless dongle like this.

I am assuming before you changed the mother board it was just fine?

Your wifi antenna is usually located behind the screen. Your wifi card is usually under a hatch on the back of the computer or under the keyboard. There are two small cables with very fragile connectors that run from the card up through the hinge to the antennas. My bet is one or both of those cables didn't get reconnected to the card or the connector got mashed when the motherboard was changed. Careful inspection may identify the problem. If you are lucky, just reconnecting the cable may get you going. If the cable or connector are damaged they still cost less than a new WiFi card. The connectors "snap" on and off directly perpendicular to the board - minimize side to side motion. There is a tiny pin or contact in the center of the connector. Make sure it isn't bent before you reattach.
