Hardware Drivers :: TP Link TL WN781ND Wireless Adapter To Access Home Network - No Connections Found
Aug 14, 2013
I installed Windows 8.1 build 9471 into my desktop. I use a TP Link TL-WN781ND wireless adapter to access my home network and the internet. I tried copying the drivers from Windows/System32/Drivres and installing them manually, I also downloaded the exe from the site but they still wouldnt connect. It would just say no connections found.

After a while when i'm browsing the web etc, my wireless connection goes to Limited and there are no other wireless networks available (when there should be 10+ networks).
When i disconnect that limited connection, there are suddenly no networks found and my wireless adapter disables itself and i can't re-enable it anymore. The only thing to restart my computer.
This occures after a couple of minutes. I had this problem before, but then it fixed itself for a couple of weeks and now i have the same problem again.
I've tried reinstalling my drivers, but doesn't do the trick..
I have an Asus N76VM laptop running Windows 8.1 Pro 64 Bit with a Intel(R) Centrino(R) Wireless-N 2230 adapter.

I have a Lenovo Ideapad Y500 laptop running Windows 8.1. i7, 8BG ram, 2GB Nvidia card--all that stuff. It ran perfectly for nearly a year. But now, the local area network is broken. I haven't done anything different or changed anything that would affect it, as far as I know. But now that it's summer, I have lots of free time but I can not lan any games with people, which sucks. So I googled and googled, tried the netsh int ip reset resetlog.txt (or whatever it is), tried ipconfig resets and stuff, and none of that works. The wireless lan adapter Media State is still "Media disconnected."
I took this screenshot AFTER I did OneKey Recovery (which is a factory reset). It set my computer back to the original settings: Windows 8, full of bloatware, etc. I did this reset last night, updated it, updated it to Windows 8.1, updated Windows 8.1, and finally, before I went to bed, tested the LAN. It worked, I was able to connect to my Dad's Minecraft world. So I set my laptop to start re-downloading my games (reset deleted all my data), and when I opened it up this morning to play Minecraft with my family, the LAN was not working again. I couldn't connect (or even find) the lan games.

The computer turn off the wireless connections and defaults into airplane mode. I had this problem with Windows 8. The option to easily toggle airplane mode on and off become grayed out unchangeable. The only way I found to temporarily fix the problem was to rightclick the airplane icon and then troubleshoot the wireless connections which would then turn wireless back on. I had the option to upgrade to 8.1 and I did and it fixed the problem for a while. It did happen again which is why I'm back on the web searching for possible more permanent solution for this. Luckily it only happened once a week ago and hasn't happened again. I was wondering if this bug was known about and if you possibly know of a way to fix.

I have a Netgear WN111 wireless adapter on my PC. Since installing Windows 8.1 it doesn't connect automatically to the router. The PC says there are no connections available, so I can't even click on the router to try to connect. If I pull the adapter out and push it back into the USB port it connects automatically. Also, when I switch the PC off, the LED on the adapter continues to flash, so I have to pull it out and plug it in again to stop that. I've tried troubleshooting, compatibility check, reinstalling the driver and uninstalling the driver and getting Windows to install one itself.

I just got a computer that comes with Windows 8 and I'm trying to get on the internet with the wireless adapter I was using on the old computer but I keep getting an error message. I am able to install it from the disc but when I go to run the program it says "Can't load ProcNICs.dll" This is the adapter I am using (version 4). The most recent driver the website lists for this adapter is for Vista. Is there a way to get this to work?

This is a 6 month Old Gateway Laptop, Windows 8 preinstalled. Broadcom Network Adapter.
I have a Buffalo WZR-300GB Router (2.4mHz, with 802.1/ 11g/b/n) all working. There are 4 wired and 3 wireless computers on the network. Wife's Gateway (Windows 8) is the ONLY one with [wireless]dropped connections. No MOVE has been made with Her Laptop or the Router.
This is the troubleshooting I've have done so far.
Uninstalled/reinstalled network adapters.Reset the adapters. Scanned Hardware changes (before/after) in the Device ManagerTurned off Power Management.Disabled the Lan (wired) connection-adapter.Removed (Forget this Connection) 2 other wireless connections from outside the home.Wireless Adapters are set to "Maximum Performance" under (edit power plan).Moved to Laptop (actually the 1st thing I did) to 2 different locations with same results, dropped connection.Under settings the Topology is all Checked, Except 2 I have never seen before. Multi-Layer Protocol, and Kernel 64 something. Anyway, when I insert a check mark next to both. I'm Prompted "Do you really want to disable this connections?" I have done both (checked/unchecked) nothing changes.Under Device Manager: Restore all Hidden Adapters, About Five More adapter showed up I had never seen before. So then I Scanned for Hardware Changes. No effect!

Laptop - Acer Aspire V5-552G-X414
Router - Asus RT-N56U
Modem - Arris DG860
Wifi Adapter - Atheros AR5BWB222
ISP - Time Warner Cable, 20/2 Mbps
Devices Connected - 2 Iphones, 1 Kindle Fire, 1 PS4, 1 Desktop, 1 Laptop
No Error Messages
Problem: Laptop won't connect at full speed UNLESS I uninstall driver and reinstall. Then it will connect at 20Mbps until I close the lid or restart the computer (I think, not sure on when it slows back down). It slows down to what looks to be 3-4Mbps every single time. It shows no error message and no reason as to why it slows down that I can tell. Device manager shows no problems. Desktop is also ran on wireless through a different adapter and never loses speed, so I'm fairly certain its an adapter or windows problem with the laptop. I've tried original driver and updated to most recent driver and still does this. I've turned off automatic update of driver in Windows 8.1 also.

Wireless adapter tripping out after upgrading Win 8 to windows 8.1? Computer used to work fine on Win 8. Now I cant download large files or watch TV or you Tube or live Football 30 feet away from the Router. Yet it worked good on Windows 8. Is it possible to return to Windows 8? I did not make a Restore USB at Windows 8 but did a Restore USB for Win 8.1.

As the title says, I'm getting a box saying "An unexpected error has occurred" whenever I try and access the properties window for my ethernet adapter. An unexpected power outage earlier in the day rendered my Windows 8 installation half messed up, leaving most of my drivers corrupt, so I had to attempt a refresh today, which solved most of my problems.
Unfortunately others like this have been cropping up since the refresh. I've looked for other possible solutions to this problem, and none have worked so far. Re-registering DLL files solved nothing, a system file check didn't do anything, and making sure I was in the correct user groups didn't solve anything either.

The other day, I built my first server (Well, not really built it, It was an HP Pavilion XD) I set it up perfectly with Windows Home Server 2011 and when I went to set up remote access, I get this (the attachments).
My router is a Linksys WRT160Nv2. I set up UPnP and did what Microsoft said here for my router: Windows Home Server Router Setup

Problem with Windows 8.1 on December 31st, and then I found a video on youtube with the same problem.
I couldn't see any wireless connections and my sound didn't work no matter what. So I ended up having to factory reset my computer. Sucks. It happened again later, but I system restored that crud and it was restored. It ever happens again without any system restore points that I can use.

I am currently having serious issues connecting my windows 8 desktop to wireless internet. It runs fine when hardwired in and I have tried to reinstall drivers I have run programs ensuring me they are all up to date. The computer is a HP Pavilion m8430f. The router is a Verizon router and I believe the company that makes it is actiontec m142wr.

Installed windows 8 on blank HD. Version was enterprise. Went through installation process, then discover that the wireless adaptor (laptop, built in) wasn't being recognized FULL stop by windows. I tried a few things. In the device manager, the wireless adaptor is not shown. However, after updating the device list, it shows one unknown device.
I looked through the preloaded drivers for wireless devices, but all of them were for USB ethernet/wireless adaptors, which as I recall from my previous installation of windows was not the type of driver that the device was using. I've also gone through the automates troubleshooting, etc, but nowhere is it even acknowledged that the device is even there. Now, my initial thinking is that it is indeed something to do with the drivers, but I'm not sure if I can find the needed ones. I'll upload more detailed information about my setup if it would be useful.

I recently got a data plan for my HTC One S. The wireless hotspot that came with it will work on my family's iPods, iPad, and our family laptop, but not on my Toshiba laptop with Windows 8. I have tried my dad's iPhone's wireless hotspot, and it works on my laptop. When I try my hotspot, my laptop will connect to it, but it will only give me limited access, meaning that no pages on the internet will load. What may be wrong with my laptop or phone?

Every time I sign into my windows 8 account at home it never automatically connects to it. I tried following the tutorial at [URL]......
However when I get up to the part where you are support to right click on the wifi connection to access view connection properties I am unable to. Right clicking on the wireless connection does absolutely nothing. I even tried clicking on it and holding and still nothing.
When I go to the network and sharing center and click on the wireless connection it pops up a dialogue called wi-fi status. However there is no button for wireless properties. I remember in windows 7 there use to be a tab where you change the key encryption type and there was a check box where you can save the password. Essentially I can't access the dialog box in page 10 of the above link.

I am using an ASUS K55N laptop, equipped with an AMD A8-4500M APU, 4GB single-channel RAM, and of course, Windows 8 standard x64.
Occasionally, anywhere from an hour to three days after a boot-up, the computer will hang while in sleep mode (screen will be off but indicator lights will remain on for about 5 minutes in sleep mode) and shut off. Upon restarting, I'll be greeted by a "Your PC ran into a problem and had to restart" Windows prompt. Of course, a minidump will also be produced. However, there is no BSOD anywhere to be found.
Upon looking into these dump files with WinDbg, all of them point toward my Atheros AR9485 wireless card's driver; either athw8x.sys or athrx.sys depending on the driver I was using at the time. I have tried several Atheros drivers, to no avail. I have tried using new drivers, old drivers, Windows 7 drivers, you name it. At this moment, I am using a Windows 7 driver. Yet, it has not solved the issue.
Verifier is disabled, although I believe my issue can be attributed to debugging. I have literally tried everything and it persists.
Attached are my SF diagnostics tool logs.

Windows detects my Ricoh AC104 on a wireless network but insists it's an HP 5Si MX and installs that driver. When it adds the printer, it loads the driver automatically and without choice or prompt. Perhaps the misidentification has something to do with the printer driver in between (Hawking HMPS1U). I need to force it to use the printer driver from Ricoh, but I've had no luck so far. Some things I've tried:
1. There's an installation program with the Ricoh driver, but it doesn't see the printer on a wireless network.
2. Going to the advanced options for the printer on the device manager, I can see the driver info but Windows will not permit changes. I tried as Administrator also. No difference.
3. Attempting to update the driver just leads to Windows telling me the (wrong) driver is up to date.

My 8.1 laptop shows multiple network connections to my Samsung Smart TV --- One as "media connections" and 3 as "other connections". Both devices are on a simple wireless network using Linksys WRT54GS.
Under the "Network" page, most of the "Properties" of the TV connections are the same except for "Serial Number" and "Unique Identifier". Did I do something wrong when setting things up? Are these extra connections harmful? Should I delete some? How?

My computer has 2 wireless cards and a gigabit ethernet port. I have my own internet and my neighbors each allow me to connect to their internet. If I were to set the Wi-Fi to connect to theirs, and the ethernet to connect to my internet would I be able to take advantage of the extra bandwidth?

On my Toshiba laptop (I've only had it since the 8th of August) under Networks it says, "No connections are available". I was playing Diablo3 and then it suddenly said not connected to battletnet. That is besides the point, but I think I might have hit something that turned the wifi off. After failing to fix it with a system restore it blue screened saying something about an error and collecting a data and that it was going to restart itself. Then it said to get more information or something like that the error code was MEMORY_MANAGEMENT. After restarting I thought it was still messed up (it showed no networks available in the lock screen) then I logged on and it still did. Then it showed I was connected to WiFi again, then after leaving for a few brief minutes it was back to no connections available. It did the blue screen thing again and restarted.

I'm trying to create a shortcut to "Control PanelNetwork and InternetNetwork Connections". I am not able to. Is there something about going to this folder that is forbidden?" If I have inserted the incorrect path please give me the correct answer.
I am preparing a lesson and a short cut to the adapters will make it easier.

I was trying to configure the WiFi on this laptop when I 'discover' this. You cant configure the network by doing a right click over the net I want to configure. This means that I cant change the password of this WiFi connection and so on.
Im not sure whats wrong. It was installed from this MICROSOFT.WINDOWS.8.1.PROFESSIONAL.RTM.X64.VOLUME. WITH.ROLLUP-1.ENGLISH.DVD-WZT and nothing more.

I decided to try a new network card due to problems with my onboard one, got a TP-Link TG-3269 after reading various reviews. most saying it installed in Win 7 with no problems or driver needed.Disabled onboard lan in bios, rebooted with new card in place, but card not recognised in device manager. Surprisingly, when I started windows troubleshooter it started working, it had reused my old onboard drivers even though it's in a PCI slot. but still not recognised in device manager.
