Windows 8.1: WiFi dropping and/or "Limited"

I also feel compelled to include my information into the record.  Since upgrading to 8.1 I've had all sorts of amazing problems with my wifi.  I have a Lenovo using an intel adapter.  I get the same limited connections and sudden dropping of internet connection.  I access a wifi to my office using a netgear 802T.  I access the internet using wifi through ATT's 2wire router.  The 2wire is more or less stable although it will go limited and claim no internet connection.  This is a lie as my internet continues to function, and I'm able to tunnel to the office without problem.  The netgear connection is very unstable.  I can connect to the internet from the office using a hardwire connection, but it frequently drops.  The connection to the office will continue to say I'm connected, but that is a lie because I'm not connected at all.  I used the advice on this forum to upgrade my intel adapter, and it worked, kinda.  The connection through the 2wire stabilized absolutely with no more problems.  The connection through the netgear failed almost continuously.  I reversed the drivers since my connection to the office was more important, and the netgear started working again so long as I don't try to access the internet through the office.  It continues to drop, but if I'm gentle with what I do, I can keep the connection most times.  I've now installed the recent 8.1 upgrade, and I fail to notice any difference.  So, Clearly, is wasn't for fixing this problem.  I'll continue to monitor this forum, and hope someone comes up with a solution.

Just to add to the record, I've been having similar problems with my ASUS t100ta tablet running 8.1 full version. Our network situation is a Netgear 3400v2 router connected to several wired and wireless devices, including an old Linksys router with DHCP disabled serving as a hub to connect a printer and an old wired computer.

This configuration has worked fine for 3 years with Windows 7 and Vista computers, and all the Android and iOS devices in the house do fine connecting wirelessly. But the Win8.1 tablet drops to "Limited" connectivity every time it goes to sleep and comes back on. The easiest way to fix seems to be to disconnect, then release and renew the IP address.

But before I figured out what was going on, I spent a day with the cable guy and a couple of hours on the phone with Netgear tech support.  Finally I isolated the fact that it was only the Win8.1 device that's having the problem.

AND the hub connection seems to have something to do with it. If I unplug the hub, the connection comes back on. As soon as I plug the hub in again, the connection drops.  Meanwhile all the other devices are unaffected.

I have not tried all the solutions offered here, yet. But will post update if something works.

Have you try simply change the scan interval of wifi device from 60 to 120?

it is work for me ;)

device manager / right click on network adapter / choose wifi adapter properties / click advance TAB / choose scan valid interval & modify standard value 60 to 120 / the apply change

hopefully its help ;)

I did the change and now it has been on for 20 hours without problems!! I still cross my fingers.

So far so good, I haven't experienced "limited connection" for a while now (1 hour already, it used to be only took 10 minutes)

thank you

Your welcome.

Mind if I ask what network adapter you are using?  Reason I ask if I wonder if various fixes work for different adapters?  Mine is a Netgear N300.
