Wi-Fi adapter is flawed
598540
I bought this laptop for my wife.  The Wi-Fi adapter in this laptop has major flaws.  This is *NOT* an isolated incident.  I was able to reproduce the issue consistently on the first one of these that I bought.  Hoping that this was a fluke, I sent it back and had a new one built.  I was able to reproduce the problem again in less than an hour of turning on the machine.

It was made readily apparent, because my wife has about 50GB of photos.  What is the most efficient way to get that to the new laptop with my setup at home?  Transfer it over the network.

In case you want to find out if your Vaio Fit has this issue, here is how I reproduce it every single time:
1) Connect to your wireless network.
2) Connect to the computer you are moving your data from.
3) Choose something with a fairly large number of files, and a large total file size.
4) Start the transfer.

You should see (depending on your local network) a fairly strong file transfer at first.  However, let it run for an hour or two, then come back and check.  The file transfer rate will have dropped from somewhere around 5Mb (in my case) to about 170Kb.  Once the network adapter is in this state, it will not recover unless you turn on "airplane mode" for your laptop.  This effectively disables the Wireless adapter.  Turning it back on will essentially reset the adapter, allowing for decent transfer speeds again for a period of time before you need to repeat the process again.

Again, I reproduced this with the first laptop as well as the replacement that I got from Sony.  This appears to be a systemic issue with the Vaio Fit line of laptops.

I hope I save someone else the trouble of purchasing one of these lemons.  I'm sending the second laptop back today for a full refund.  I'll be looking at Samsung or Lenovo next, I suppose.

The product arrived in good condition.  It works most of the time, but occasionally cannot find the router signal or drops it for whatever reason.  Once and awhile, I have to physically move the PC and wireless adapter right beside the router in order for it to reacquire the signal.  This doesn't happen to often, but is a pain when it does.  It's like the wireless adapter can't find the router signal suddenly for no apparent reason. Rebooting doesn't always fix the issue.

The Edimax Wireless Mini USB Adapter is a great little WiFi Adapter.  The first time I installed it, it set up and worked like a dream... Fast, Good Connections, Great Software for managing your connections (much better than the built in Windows 7 stuff).  The problem is when you remove it from some systems.  I made the mistake of "ejecting" the unit (Safely Remove Hardware and Eject Media) and then reinserting into the USP port... and...nothing!... The rest is history... I tried uninstalling, reinstalling, uninstalling and reinstalling... disabling other wireless adapters, etc.  It appeared the unit was "dead".  I eventually had to Open Device Manager and watch for the unit to appear upon inserting into the USB port.  Then, I manually installed the driver from the CD ROM.  My system then recognized the unit and I thought I was set... until I restarted the System and it wasn't recognized again.  I finally rectified the problem by once again uninstalling everything to do with Edimax, inserting the unit in the USB Port, manually installing the driver, manually installing the connection software and then restarting the system.  This seemed to work for the time being.  I am not a Computer Genius, but I am not a newbie either.  This thing seems to not ever want to be unplugged from my computer... if it is... well, read above.

If you are in need of a nice little WiFi adapter and have a USB port that you don't use and don't need and don't mind leaving this plugged in forever then I recommend.  If you want to take it with you... well, I would advise caution.

I am sure that on some systems this would not be the case... but On mine (Windows 7, couple years old with all updates, etc) it wasn't.  I would recommend buying a more expensive brand if I had to do it over again.

Good product, except that it was not easy to make LAN adapter work properly. I'm using 64-bits Win10. Installation of the motherboard drivers was smooth till the system reported errors with NIC driver. Had to restart the computer and install the driver again and again, but not lucky. Under device manager, the Intel Network Adapter was listed and marked as function properly, but network was down, and system complained no network adapter was found. After struggling about two hours, finally l made it work. What l did was uninstall everything under device manager/network adapter, including the hidden ones. After system restart, reinstall the NIC driver. Then it worked.

The wifi adapter - Qualcomm Atheros QCA9377 - repeatedly dropped connection and required restarting.  Only when in the same room as the router would the wifi work, and even then it did drop connection sometimes.  We have another laptop and our phones, and have never had these connectivity problems.  Returned this to Amazon and got a Dell Inspiron 7000 13".  Should have just got that to begin with.

Item did not connect to wifi. Wifi connection timed out repeatedly even after resetting. Password
Was checked and rechecked to ensure it was accurate.

I'll make this short and sweet. The adapter works great. The fact that you HAVE to use their included wireless management software stinks.

Does not connect to wi-fi properly.
Cannot use it if it does not connect.
Poorly designed.

It drops wifi signal every couple days, requiring a restart. That always does the trick, though.

Tested 3 different wifi adapters. My Netgear and Panda wireless devices get 70mpbs down, 11 up on average. This EDUP adapter gets around 5kbps on average. Would like a replacement. Seems like I got a defective unit.

Don't bother. Keep looking if you are installing into a Windows 8.1 PC. Works great when it works. Tried the latest drivers for Windows 8.1 as well as the more current beta drivers. With both drivers the A6200 would suddenly drop the wireless connection. Could get back if reboot or unplug/plug the adapter. Since this is a PC used by my non tech wife having issues is a big thing.
Since I have a Netgear R7000 router I figured I would get a wireless adapter that would match the AC speeds of the router. Know that this speed makes no difference with Internet related activities but might speed up internal activities.
Went back to my old reliable ASUS USB-N53 adapter that just works.
With my experiences with wireless adapters I should have figured this would not work well as the chipset is Broadcom and in my experience not a vendor that makes reliable firmware for the wireless adapters. The ASUS is a Ralink chipset and in my experience more reliable drivers/hardware. Your experience my vary.

A 6 year old Toshiba laptop with an Intel Wi-Fi adapter quit working after this update.  Downloading the driver, then installing this adapter got us back Internet access.

Connection using WiFi IP address only works when network cable is plugged in.  What's the point of having WiFi?

This one goes back.

Wireless adapter stopped working after one day.

I spent hours troubleshooting before finally just plugging in another adapter and it worked just fine.

The case is cheap, hard to get on correctly, and the wireless adapter sucks. Overall bad buy.

Took only a while for me to decide to return this. Biggest problem with this unit is the WiFi adapter just doesn't work well. It shows a great signal and connects to my high speed network but barely gets any data. Seems to be a driver problem. Next problem is this is not scalable to fit a 50 inch or better screen. 42 fit ok. 50 inch leaves a gap on right side that can't be fixed. A shame but basically useless as is.

It works when it wants to, setup is a pain and a half to get to finally work on wifi

The USB adapter is not suitable to my Express Card Linksys adapter. The computer would not recognize the USB when plugged in, no lights. Possibly the Express card is PCMCIA based for interface drivers. I had to return the card as DOA, my wifi adapter would not function but is brand new from the box.
