I just purchased a Toshiba Satellite S-50 A and am having problems with the Qualcomm Atheros AR956x wireless network adapter that came with it.
With the wireless router at my home, the internet frequently cuts out. When it does, I run the Windows Network Diagnostics, and get the message: "problem with network access point or wireless adapter" with a green check and "fixed" next to it. I will then have access to the internet for another 15 seconds to a minute before it cuts out again and the process needs to be repeated.
The problem IS NOT with my service provider, as I have an older Toshiba Satellite that I was running concurrently on the same network and not having any connection issues with.
The problem IS ALSO NOT with the actual wireless adapter hardware, as I don't have any connection issues with the Toshiba Satellite S-50 A at my parent's house with their wireless router.
I figure the problem must be between the driver and my router (and possibly windows 8), but the wireless adapter driver is up to date, and I have tried installing other drivers, which has not fixed the problem. Toshiba phone support also had me wipe my computer to out-of-box state (even though it was a brand new computer), and this also did not fix the problem.
Any suggestions? It's a brand new computer from Toshiba direct and the internet is virtually unusable at my home on this particular computer.

Resetting the SSID will not solve this problem. I have the same computer (Satellite S-50 with Qualcomm Atheros AR956x). There is really only one solution I can think of and that is for Qualcomm Communications, INC to produce a new driver for the adapter that will stabilize the wireless connection. If anyone else out there has a legitimate solution I am very interested in hearing it.

I agree the problem is with the driver, and the lack of a fully compatible, functioning one. This is definitely going to be my last computer with a Qualcomm adapter, and probably my last Toshiba too, as their phone support has been pretty terrible.

I have the same problem, my new Toshiba Satellite C50D with Qualcomm Atheros AR956X wireless network adapter will not connect to my home wifi router, a (few years old) Sitecom with 802.11g wifi standard.
Or actually, it randomly does and suddenly disconnects and won't reconnect for days.
It is ridiculous but the only way to connect my new laptop is by plugging in a (few years old) wifi USB adapter (it is a Edimax EW-7711UMn). This worked plug-and-play immediately, and automatically activated a "WiFi2" menu. So now I keep the default "Wifi1" disabled.
Nevertheless I tried to find ways to get the embedded wifi to work.
I tried downloading and installing new drivers for the Qualcomm adapter but they don't work either.
Enabling/disabling "ADhoc 802.11n" in the wifi adapter configuration doesn't work either.
Toshiba and Qualcomm should better care for backward compatibility, this is extremely annoying.
Should anyone fin a solution I will appreciate it.

I have a the same problem with my Satellite Pro.
Research on this forum allowed my to find tips to help (but not solve 100%) this issue.
Try using your laptop connected to the AC adaptor... Do you see any improvement?
Is you do (like I did) two things to do:
-Device manager, open the device and on the tab Power Management, uncheck "Allow the computer to turn off the..."
-Control Panel, Power Option, either use the "High Performance" or modify the plan settings (in advance power settings) so the wireless adaptor is not affected by the power management.
(these are for windows 7)

I was also having connectivity/speed issues with my W-8.1 L70 laptop. However, I think I found a solution. The driver version for my AR956X wireless adapter was 10.0.0.270. That apparently was the driver that was loaded during pre-setup or final setup of the system. I reverted back to version 10.0.0.263 (which was still on my computer) and have had no further issues. In fact my surfing/downloading seems faster and more reliable than it ever has. If the 10.0.0.263 driver is not on your laptop, you can get it from the Toshiba Drivers section of the support web page. For the record I also tried the latest driver version from Qualcomm (10.0.0.274), it behaved just like version 10.0.0.270. In other words it didn't work very well!

I see a lot of people, including me, have been having problems with the same thing. It apparently has something to do with the drivers in Windows 8.1. One person apparently fxed the problem by changing back to a Windows 7 driver for the Qualcomm. But the Qualcomm only accomodates the 802.11n level (which is what you need) in the ad hoc mode, which I gather is NOT what you want for Internet connection. When I went to the Linksys Help (855-44-5947) the lady was very quick to recommend the new AE6000 adapter, which connects to the PC by a USB port and has "full" 802.11n capabilities. I ordered it for $50 plus tax, but then I went to Amazon and found an earlier version of the same thing, used but certified, for about $20. So I expect to cancel the order for the $50 model.

Thank you TroyKleffman. I recently bought a Lenovo laptop and was having a problem with the Atheros AR956x. Every time I turned on the laptop, all other devices connected to wireless lost connections (as did the Lenovo). Your answer of installing the 10.0.0.263 has resolved the issue and saved me a lot of earache from my family!

I've also ben having problems with my Toshiba. I bought it two weeks ago and the internet is extremely slow on just my Toshiba Satellite. I've tried downloading previous updates on it and uninstalling the up to date drivers but it won't let me goback past 10.0.0.274. I also don't know how to reinstall the driver once I uninstall and delete it (I haven't done the deleting part yet but I read somewhere that that helps). Any suggestions? Or can anyone tell me how to install the 10.0.0.263 driver? Also, this Toshiba came with Wndows 8.1

This is a power setting for when the laptop is working off the battery alone. Microsoft has a detailed explanation, but depending on the power management setting in windows and the default settings for wireless, the wireless may go to sleep frequently waiting for activity, and if the driver isn't well written to work with this sleep and awake process, the internet connection loses a LOT of data and seems very slow. You can make the wireless internet reliable by searching for power management in windows and going into the power profile for the wireless and setting it to maximum performance all the time.
Works great on my C55. Too bad I had already ordered a replacement wireless card, but it is a powerful dual channel one instead of the single channel that comes in the laptop.

Previous reply says "Microsoft has a detailed explanation..." Would have been nice to have a link to that.
Just WHAT is the solution they provide? (MS solutions seem to work about 20% of the time).
Also, several previous posts indicate the solution is to install the 10.0.0.263 driver.
I thought "wow, my problem is solved"--but looked and 263 is what I already have, SO THAT DRIVER IS NOT THE SOLUTION.
I DO have this phenomenon. My expensive i7 laptop is next to useless due to dropped internet connection. Constantly doing WiFiicon, Disconnect, Connect automatically, re-Connect clicks. I am one unhappy person with Toshiba right now--but no way out. What do they care...product is sold.
By the way, the 263 driver is what is on the Toshiba site as current driver for my computer,

POSSIBLE FIX FOUND........................
Look at this page.
The fix may be as simple as running
netsh winsock reset

I just had the same problem with my daughter's new computer.
I uncheked "Ad-hoc N" on the computer, went to the router and uncheked use "both 20/40 mhz".
Now we have 150, but kiss good by to 300.
Router is Netgear WNR2000v4- 300, so I found this:
Why am I only receiving 150Mbps even if I set the mode to 300Mbps?
The 20/40MHz Connection is enabled. This is a feature on the router to make the 2.4GHz frequency connection become more stable on the router since there is a lot of interference when using this frequency. You can enable/disable this feature by going to Advanced > Advanced Setup > Wireless Settings.

Sept 2014 Windows updates offered me an update
Qualcomm Atheros Communications Inc. driver update for Qualcomm Atheros AR956x Wireless Network Adapter
which I installed thinking wow, they've fixed it.
Have had two internet drops wih the new driver so far.
The date on the NEW driver is (wait for it)...................... 10/17/2013 !!!!!
version is 10.0.0.270
Ain't it great to get a new! driver that is a year old?
By the way, the CURRENT driver download from the Toshiba site for my computer delivers
10.0.0.263 8/15/13. That also is very interesting--that Micrsoft is delivering a Qualcomm driver of later version than Toshiba's site.

Well, my connection issues returned. What I've recently discovered is that if I set my 2.4ghz gateway (cisco dpc3825) to standard channel instead of wide channel...the connection between my L70 laptop and the gateway is very stable. i'm not sure if it's my gateway, or the Atheros AR956x wireless adapter that's the problem. :-(
10-13-2014 09:11 AM - edited 10-13-2014 09:13 AM
Well, when my gateway is set to standard 20MHz channel width...my laptop adapter says the wifi connection is measured at 72.2Mbps. When set to wide channel 40MHz the speed says 150Mbps. So i'm not sure if that answers your question. anyway, for some reason my laptop has issues with the wifi connection when the gateway is set to 40MHz, and i'm not sure why. my isp download speed is only 65Mbps so i don't gain much by using the wide channel anyway.

I would like to thank Nerl for the link that has resolved this issue for me.
into command prompt and enter
netsh winsock reset
laptop is running fine now thanks again nerl

I was having the same problem with my connection and tried all suggestions, then I unplugged my wireless mouse and my speed shot up to max. I have 3 USB ports and I tried all of them. As soon as I plugged in the wireless mouse (mouse wasn't even on) I watched my download speed drop to 0.2 KB. I have no idea why this is happening but as long as I don't use my new mouse, my connection is fine. Any ideas?
