Question about Dell Inspiron 6400 Notebook

1 Answer

WiFi turns itself off

After i have switched on the laptop and working on WiFi , the WiFi connection switches off on a unexpected moment after pressen the knob on the front side it will switch on again on this moment i am working with a sweex WiFi usb , and that is working perfect , but i want to use the internal WiFi connection .
On the same time sometimes the keybord and touchpad won't work , when i take the batterie out and plug it back again everything is normal again .
This laptop is just over a year old and the problem with the WiFi is from the very beginning .
I know it's difficult but can you give me some suggestions .

I have a Dell inspiron 6400 and also have a problem of the Wifi turing itself off when in use. I then have to restart the laptop to reconnect the Wifi until it turns itself off again. It doesn't have a trend of when this is likely to happen.

Hi Troy,
Don't know if this will work with your Dell, but on my Averatec, I had to do the following.
Go to Start>Right click on My Computer and select Properties. Click on the Hardware tab, and Device manger. Click on + by the Network Adapters. Right click on your wireless, Intel or Broadcom wireless adapter, and click on Advanced. Findd the Minimum Power Consumption and make sure it is disabled. If you have a Power Management tab, click on it, and uncheck both boxes.

Good Luck!

SOURCE: WiFi turns itself off

You may want to consider replacing the motherboard, since the Wifi 'is on the motherboard' and the Keyobard connects directly to the motherboard. You may want to check to see if there are any firmware (BIOS) updates available for your particular model.
Also, check Acer's or whoever your manufacturer is, on their support site to see how to perform a BIOS reset.

Kyocera milano 5121 recognizes and remembers my att uverse gateway, but switches to disabled within a few moments.

Click on your wifi connection and have it forget the uverse connection, and then turn wifi off.. Then reboot your phone. When it comes back up, turn wifi on, search for your uverse connection, put in your password, and see if that fixes it. Sometimes the connection becomes corrupted.

I turn on net book plug in dongle that connects then i press internet connection it comes on for about ten seconds the goes off

What is going off - the internet or the netbook itself? When you say internet connection, do you mean the wifi toggle switch or the windows internet settings pane?

First, check and see if there are any buttons that get stuck (power button or wifi toggle button). Second, try using a software switch to turn on your internet connection.

I am not getting internet connection. It keeps saying that there is no ethernet adapter connected but I have the ethernet cord plugged in. When I turn the switch on the right of the computer for the WiFi,...

The Ethernet is still can't use for WiFi so far,but it isn't not a problem for the WiFi connect matter because there is a Net Work card itself for most Laptop today including Dell Inspiron 1525 PC Notebook, it may be the Drive matter for the Net work system,you can update it ,or there is no WiFi Net work in your place obsolutely.

Wifi switch is turned on however, when i try to search for a wireless network i get a message saying that i need to turn on my wireless switch

So I understand that your wifi card doesn't work?If that is correct go to Toshiba site and check their support-from the other computer-of course.If card is dead, you will need usb wifi.

Where is the wireless switch

Okay the laptop is only pertaining to itself, so depending on the laptop make and model there is a button that has a little tower above the keyboard or a left to right switch somewhere on the chassis. If that is turned on, then make sure the wireless network adapter is enabled in the control panel
