Hey, need some help please.  Thank you in advance.

I can't figure it out for the life of me.

Its a Sony Vaio 14n13cxb (Tablet/Laptop) in one, running Windows 8.1.

The laptop has a terrible wifi connection, compared to 4 other computers.  the sony get half of the speed or less and disconnects frequently.  The router is only about 10 feet away in a closet.  No other computers have an issue. I'm baffled.

 

Things that have been tried:

*A different internal wireless card

*Sony updates

*Driver updates

*External wifi adapter (this works, temporarily, the length of the wire allows the wifi adapter to get about 3, 4 feet closer to where the router is, and the speeds become normal without disconnecting issues).

[just a guess]

If a different wireless card reacts the same way back up one step more - the power to the card. It sounds like you are getting a signal but a very weak one.

Wow, power to the card, didnt even think of that (so simple). I assume the power is provided by the slot that the Wifi card plugs into on the motherboard, right?  Meaning, in order to fix the issue I would need a new motherboard, correct?  Thank you!

And maybe this will help you nail down the culprit.  It could be that the laptop is just unable to cope with multiple interference.  Have you tried shutting down the other pc's to see if then your laptop gets a stronger signal?

hmm i dont think that link helps in my situation because ive tested other computers, in the exact same spot as the problem-laptop and they have no issues.  is it the wificard slot on the laptop motherboard that powers the nic? i have a strong feeling thats the issue

So the external Wifi adapter runs fine and does not disconnect? Open Device Manager, right click on your wireless adapter, select Properties and under the Details tab select Hardware IDs. Copy and post the first line shown.

That is an Atheros AR5B95 and unfortunately the latest driver I could find was for Windows 8 and not 8.1 even though it is dated 2014-12-22. It may work for 8 as it lists being for 8.1 but looking at the inf file it shows  OS 6.2 which is Windows 8. 8.1 is OS 6.3. I would be a little concerned installing it. You would to at least make a restore point.

 

I can link to the driver if you like. It needs to be installed via Device Manager > Update driver.

 

You say the USB adapter works fine. Is there any reason not to use that instead?

ive already updated the driver, didnt help.

dont want to use the USB adapter because its a laptop, and no one wnats a huge adapter (or wire, and then adapter) sticking out of it.

i already tried a micro wifi adapter and it wouldnt even install.  since theres no guarantee a micro one works as good, im going to leave that as very last resort.  i cant afford to waste anymore money towards this laptop, it was overpriced as it is.

Yes, there are no guarantees but the edimax does show 8.1 drivers listed. I have heard some bad things on 8.1 wireless. You may want to try the steps here and see if there is an improvement. Pay special attention to the netsh commands
