Pcg81312l wifi driver wireless - Sony Nice Vaio Pcg-81312l Laptop Notebook 500gb 6gb I7 2.2 16.4" Pcg-81312l

The OS itself does not contain wifi. Wifi is hardware that is installed in the device. AS far as the OS is concerned, yes the OS does support the wifi networking protocols. You MAY have to load the wifi adapter driver(s) for you device if Windows does not have a native one that is compatible, however. You can determine whether or not the driver is installed by going to the DEVICE MANAGER and looking at NETWORK ADAPTERS. If there is no wireless adapter present or there is an exclamation mark alongside the adapter, then you need to load the driver to get wifi functionality within the OS.

step one (guessing #4 down fails)

1. are you at home, Starbucks ,air port or at work, (who's wifi)
2. do other wifi devices work there., PC, TV, cell phones on wifi or ?
3. if yes,#2, then move the laptop closer t the wifi router.
4. If no and device manager shows 701 errors "? that means the drivers are wrong even infected not using HP.com drivers for your unstated OS. windows 7?
5. on my HP laptops, it takes 2 drivers from them to work wifi,
6. the wifi card driver must match (of up to 3 or more used new)
7. and must have the control panel BUTTON driver working to control wifi.
8. did you up grade it W10 and now wifi is dead , ? oops!

dv6-2155dx , seems was window 7 new, and frozen there,.
HP has no support now for this old PC. (besides asking on THEIR FORUM)

HP has short list of wifi cards they used, and only those work
HP blacklists all other non HP cards (unlike wonderful DELL)
so wrong cards are doomed to fail., as is w10
the correct card (1) is here
Intel 5100 512an_hmw Half Mini Pci-e WLAN WiFi Wireless Card 572507-001 for HP Laptop. for windows 7 only.
802.11b/g/n WLAN

in that post note 2 the cards used. new. all 3 HP certified.

visit the official website of sony...it may help you...

Make sure that driver is installed properly. If it is, check for wifi switch. Make sure it is turned on. In some laptops do not have switches, they use the functions keys to turn them on. Use Fn+F2 or Fn+F3. Also, make sure that you just have one wireless utility activated in the computer. It is more advised that you use the Windows Wireless utility which is more compatible with most types of routers.
Lastly, check your wireless card and the wireless router if they are wireless a,b,g or n. If the router is wireless n, your card should also be wireless n. If your card is just b or g, it would not work.

Hi

You can;t install your wifi driver please install the wifi driver

Such Problem are caused when there is no wireless driver/wireless assistance software on the Laptop(COMPUTER SYSTEM)

SOLUTION.
Get the Wireless Driver of the External Wifi you use with the laptop , Re - Install it and also try to Install the WiFi assistance.
if the problem persist then you have to change your External Wifi

situation 1 :- if your (ur) notebook wifi driver are pre-installed by ur operating system then there may be the case of wifi hardware problem
situation 1 :- if not then check if the wifi driver are installed or not....
re-install wifi drivers . and even the problem persists, then please contact ur notebook manufacturer (for free repair if ur notebook is under warranty time period)

Question is did you download the correct WIFI driver. Dell likes to throw whatever they have in the bag in their computers. Thats why you see 2-5 different wifi drivers for one laptop on their site. Go to Dells site download all the wifi drivers and extract one at a time until you see the little wifi symbol pop up by your clock. Try the broadcom driver first they like to use that one alot.

With this Asus wireless B adapter even the new driver dont support WPA wireless security , because right now sicne WPA is a much newer and higher type of wireless encryption only some wireless B adapter supports that and sorry to say this wireless adapter that you have don't support it even with the latest driver so it will be better to get a new wireless G adapter that supports WPA 100% , you can get the wireless adapter from Asus or from other wireless device manufacturer like Linksys, Netgear. Dlink and Belkin....

does your wifi detect available wireless network when you try to check it? are you using a wireless router? do you have a 169 ip address? try resetting your wireless router
