I am currently using a 17 inch external monitor with my Dell Inspiron 9100 laptop. I would like to remove the laptop monitor. I have tried this and everything work fine except my wireless signal drops off. The antenna is in the monitor. Is there a way to connect an antenna to the laptop to get around this?

Hello tae111

and welcome at Gladiator Security Forums. Enjoy our small board.
Usually WLAN function will work as long as you don't disable or switch it off. Mounting an external display device does not harm up the WLAN functions!

Did I catch it corret? Please correct me if I am wrong. You closed the display of the laptop, connected the external screen with the notebook via data cable running it that way right? Or did you disasssemble the display of the notebook completly?

I took the laptop monitor off the laptop. I had it off for a few days. My signal was very week on my wireless network. I treid a few things to fix this but nothing worked. I just took a guess that the antenna was in the monitor . I put it back on and signal was back to normal. I would like to find a way to take it off as it does not work and am now using a 19 inch one. I am looking for a way to possibly hook up an antenna to the laptop base.

Happy New Year tae111

best wishes to you and ya folks.

Well must admit I've heard and seen a lot of unusual thing in IT business, but this is something special. First you're right. The antenna is located in the frame of the display. Usually it covers all sides ot the frame. To remove it, you have to open the frame and remove the antenna.

Your idea to hook up any other antenna-like building might be correct, but theye WLAN antennas have a defined and tight specified electrical and radio tedchnical parameters. Any changes beyond that norm will sure cause problems when using it.

Btw. any self-constructions might run into problems with mobile phones and related radio signals, so think over please if you're gonna go that way.

Did you have the vertical line problem with that 17 inch in the 9100 ? I have replaced a few of those already..see here.

In any case the wires to that mini PCI card which is your wireless card look like this including the antenna behind the bezel..you can take out the antenna and use it or make your own.

Adding Mini PCI Wireless Card AND Antenna

DocWatson's description is as follows:

"The antenna consists of two wires about 1.5 feet long each, with tiny gold coax connectors on one end each. Once the NIC is installed you need to open the laptop case again. Connect the antennas to the coax connectors on the NIC, then wrap them around the perimeter of the inside of the case. I used RTV to secure mine, but super glue would do as well. This NIC is now providing dual space diversity on the receive antenna, which is the same way most WAPs and wireless routers transmit. My signal strength is through the roof compared to my old Cisco card."


I think you will also find this link helpful..since many of us in the past added mini pci cards to laptops that never had the wireless capability in the first place.

Then you can also go to ebay and see what they look like and get an antenna

here is one that is is built into a circuit board to save space rather than a full wave coaxial type.

Thanks to all for the help. I did not experiance the vertical line problem. My screen just went dark. I could see the paged loading faintly through the black screen so I think it was the bulb. I am using an external monitor until I can get around to replacing it. To save space I removed the laptop monitor and thats where the problem began. I have since put the old monitor back on and have the external one next to it. Rather than messing with the wires of the internal antenna I think it will be easier just to fix the old one.

Thanks again
