1390 WLAN Mini Card
i am having problems with my 1390 Wlan Mini Card included in my inspiron 6400.
it only connets sometime to my wireless network.
does anyone else have a problem were it works for a while ok than it goes very slow than it disconnect and everythime i restart the pc i have hard time finding the wireless network.
it works perfectly with my other usb network adapter.
Customer service told me it's a software problem but i really don't think so.
i just like to know if someone else experienced these type of problems and if it was software or hardware.
thank you

I finally found the problem and fixed it, without help from dell support. It turned out to be the internal antenna. In Windows, go to Device Manager, open properties for the 1390 card, go to Advanced tab, select Antenna Diversity. The default value is Auto. If I change it to Aux, the card can connect to the router very quickly and maintain a stable connection. If I change it to Main or Auto, the card has trouble connecting to the router and if it does connect, the connection is unstable, and also the sensitivity is very poor. It can detect much fewer hotspots than using Aux. This has nothing to do with the position of the router.
To see if it is a problem with the card or with the antenna, I opened the hinge cover and removed the keyboard to expose the card under the keyboard. Both antenna cables were well connected. I disconnected the Main antenna cable (the white one). The Aux antenna cable(the black one) stayed connected. Then set Antenna Diversity to Aux, tested the connection. It worked. I then connected the Aux cable to the Main connector on the card, set Antenna Diversity to Main. It still worked. Then I disconnected the Aux cable, used the Main cable to connect to each of the two connectors on the card, set Antenna Diversity accordingly, and tested the connection in each case. In both cases, the connection was bad. After these tests, it can be verified that the Main antenna, not the card itself, is probably bad. But I'm not sure why the Main antenna is not working well. The antenna is inside the LCD panel. To troubleshoot the antenna I may have to disassemble the LCD panel assembly. That may void the warranty so I decided not to take the risk, even though I know how to do that. BTW, getting access to the 1390 mini card does not affect warranty, as tech support said.
This is my first time I order a Dell product and will be the last time, given so many troubles I had.

It's a shame Dell is still unloading these cards on its good folk that support their business. 1390 problem reports are all over this and other forums. After hours of troubleshooting mine, I finally got it to work. My lessoned learned here is do a bit more research before buying. Trust is something earned and I use to trust Dell.

did you run the diagnostics? - did you get an error?

Tried this as well and I believe (cross fingers) that it solved the problem...
I have 3 year complete care so I will keep an eye on it and just get them to fix it later if it crops up again....
Thanks again!
