Learn how to fix slow download and upload speed on Windows 10 by following quick easy steps. When you install a hardware or plug in a new device Windows 7 / Vista automatically selects the best driver. But sometimes you get a CD with your device th. Windows 7 adds native Virtual Wi. Fi technology from Microsoft Research. Wi. Fi is an incredible technology that has transformed how and where people used computers, however besides advancements in speed, range and security, very little has changed how we use wireless networks. Since 2. 00. 2, Microsoft Research has been exploring a fascinating idea to virtualize the Wi. Fi adapter, turning a single piece of hardware and radio into virtually (pun) unlimited adapters. Years after the project was seemingly abandoned, it is now uncovered Virtual Wi. Fi technology has been baked into the Windows 7 networking foundations. In essence, how Virtual Wi. Fi works is very similar to how virtualization works for operating systems which most people are familiar with – the transparent sharing of limited hardware resources to many operating systems. Virtual Wi. Fi, abbreviated to VWi. Fi, is a software layer that abstracts the wireless LAN card hardware into multiple virtual adapters. The software handles the connections of each adapter to ensure every adapter has an opportunity to connect to their respective networks limited by time. The result is an operating system none- the- wiser and acts as if you have multiple WLAN hardware adapters working independently. If you like to dabble in a little hardware jargon, here’s an obligatory architecture diagram which explains how Virtual Wi. Fi works in Windows 7 in much more detail. If you got lost somewhere between the dotted lines, read on. You might be wondering why anyone would ever need multiple WLAN adapters on the same PC, well to be honest, you don’t need but its sometimes good to have. In any case where you’re connected to an existing wireless access point and want to connect to another network whether that be a separate access point or even set up an ad- hoc connection, Virtual Wi. Fi will allow you to do just that. But perhaps the scenario that is more appealing is the idea of a mesh network. In a mesh network, every client becomes a repeater, growing the network organically as more clients connect. Virtual Wi. Fi enables this, since every client can become an access point too. Now you might be asking, “I’ve looked at every nook and cranny of Windows 7 RC, how come I haven’t seen this feature?”. Surprisingly, the feature is in Windows 7 today and has been for quite some time apparently, but hasn’t been exposed due to a lack of driver support. WLAN hardware vendors are required to recompile their drivers with a couple new additions. The good news is that Virtual Wi. Fi functionality is going to be a requirement for WLAN drivers under the Windows 7 certification logo so expect to see it soon. Assuming it all goes to plan, the feature will be automatically exposed.“On Windows 7 and later, the operating system installs a virtual device if a Hosted Network capable wireless adapter is present on the machine. This virtual device normally shows up in the “Network Connections Folder” as . This virtual device is used exclusively for performing software access point (Soft. AP) connections . The lifetime of this virtual device is tied to the physical wireless adapter. If the physical wireless adapter is disabled, this virtual device will be removed as well.”Unfortunately as it seems, the implementation of Virtual Wi. Here I found 2 best WiFi hotspot software for Windows 8.1, Windows 8, Windows 7, PC and Laptop. So check out the best WiFi hotspot software. If your wireless adapter keeps disconnecting on Windows 10 and yellow triangle alert appears, it's a driver compatibility issue. Here's fix. Wifi scanner software - Wireless network scanner app for Mac OS X WirelessNetView - View wireless networks information on Windows XP. Wifi Collector. ![]() Fi in Windows 7 is not as liberal as the research prototype. In Windows 7, you are limited to exactly one virtual adapter. However by looking at the impact of multiple virtual adapters on latency and performance from their original research report, this is probably for good reasons. More technical information aimed at hardware vendors and developers is available at the Win. HEC 2. 00. 8 session, “Wireless LAN Enhancements In Windows 7”, Power. Point downloadable here. You can also learn more about their original prototype and research paper here. Obviously this feature isn’t as glamorous as the fancy new wallpapers or as practical as Aero Snap in Windows 7, but I think it represents one of the many silent revolutions in Windows that probably won’t be recognized and taken for granted for releases to come. I’d be interesting to see if Virtual Wi. Fi catches on, and how new networking scenarios can be enabled by developers and hardware vendors. Ultimate Windows 8 Wi. Fi Troubleshooting Guide. If you’re running Windows 8 or recently upgraded, you might have run into some frustrating Wi. Fi issues. Windows 8 is inherently a different beast than previous versions of Windows and with it comes a new set of problems. I never encountered too many wireless problems in Windows 7, but have run into several with Windows 8. In this article, we’ll go through a couple of the most common problems with Wi. Fi connections in Windows 8 and how to troubleshoot them. Most of the problems occur with those computers that got upgraded from Windows XP or Windows 7 to Windows 8. Either the driver is out of date or the adapter gets disabled or something odd like that. Let’s get started. Limited Connectivity Message. If you’re getting that annoying limited connectivity message in your task bar in Windows 8, it’s really hard to tell what the problem is. You basically just have to try a couple of things and hope one works. The cause could be anything from the network adapter to the wireless router to a bad network cable. I’m only going to mention a few of the major reasons here, but scroll down to the Other Troubleshooting Tips section if none of these fix your problem. Method 1 – Troubleshooter. The first thing you can try is to run a couple of the network troubleshooters built into Windows 8. A lot of the time, it can solve your wireless or Internet problem for you. To open the troubleshooter, open the search charm and type in troubleshooting. Then click on Troubleshooting, the first option. Now you want to click on Network and Internet. Finally, you will see the different troubleshooters available for fixing wireless and Internet problems. The ones you will want to run are Internet Connections and Network Adapter. Method 2 – Reset TCP/IP in Windows 8. You might also get a message like this when running the troubleshooter: Wi. Fi does not have a valid ip configuration. In this case, you can reset the TCP/IP stack and Winsock and see if that works. To do this, again open the search charm and type in command prompt. On the first listing, right- click and choose Run as Administrator. At the command prompt, type in the following two commands, one at a time and make sure to press Enter after each one: netsh winsock reset catalognetsh int ip reset c: \resetlog. Hopefully, your wireless connection is working at this point. If not, skip down to the bottom section which has more troubleshooting tips. Wi. Fi is Disabled or Greyed Outin one odd case, I had a Surface tablet where the wireless was disabled and I could not even enable it. For some odd reason, the On/Off toggle switch for Wireless Devices was greyed out like below: The first thing you can do is try to diagnose the connection. To do this, open Network and Sharing Center. You can simply right- click on the network icon in the task bar and choose it or you can open the search charm and type it in there. Now find the wireless connection at the top and click on the blue link: A new dialog will pop up and here you’ll see there is a Diagnose button. Go ahead and click on that and let Windows try to fix it for you. The next thing you can try is to restart in Safe Mode, Network Enabled and try to turn on the Wireless there. For some reason on certain computers, the option is not greyed out in safe mode, so you might be able to enable it there and then restart in normally. Read my previous post on how to boot Windows 8 into safe mode. The other thing you can try is to disable and then re- enable the wireless network adapter. Again, open Network and Sharing Center and then click on the Change adapter settings link at the left. You can see it in the second screenshot above this paragraph. Right- click on the wireless network adapter (not the Ethernet one like shown above) and then click on Disable. Once it’s disabled, go ahead and right- click again and then choose Enable. Now try to go to Wireless in PC Settings again and see if you can enable Wi. Fi. If this doesn’t work, again drop down to the last section which has more Wi. Fi troubleshooting tips. Wi. Fi Not Connecting from Sleep or Hibernation. If your Windows 8 machine is disconnecting from the wireless network whenever you return from sleep or hibernation or any other standby state, then your problem is probably with a power- saving option set on the network card. To fix this, you need to open the search charm and type in Power Options. Here, click on the selected plan and then click on Change plan settings. Then click on the Change advanced power settings link. Now scroll down to Wireless Adapter Settings and make sure the Power Saving Mode is set to Maximum Performance. Other Troubleshooting Tips. Check Network Card at Compatibility Center. You can check to see if your wireless network card is compatible with Windows 8 by visiting the Capability Center. Go ahead and type in the name of your wireless card and you should get a little report like this: It’ll have a little blue logo if it is compatible or not. You can also check Windows RT in addition to just Windows 8. So this is a nice site to check out if you are having issues with your Wi. Fi network, especially if it’s not showing up at all in Windows 8 or it’s got a yellow exclamation sign in Device Manager. Check Network Adapter Settings. Open Network and Sharing Center, click on Change adapter settings and then right- click on then wireless network adapter and choose Properties. Now scroll down in the list box until you see Internet Protocol Version 4 (TCP/IPv. Properties button. Finally, make sure the Obtain an IP address automatically and Obtain DNS server address automatically radio buttons are selected. Check Wireless Switch. On most laptops, there is a wireless switch or button that can be toggled from on to off. Make sure you have that button set to On or press FN + F8 to enable the wireless card. The switch can be anywhere (sides, front, back, etc), but there is usually an indicator light so you can tell when it’s on. Uninstall in Device Manager. Another quick tip is to go to Device Manager, right- click on your wireless network card and choose Uninstall. Then reboot your computer and it was automatically be detected and reinstalled. If it’s still not working after trying this, then read the next tip, which is updating the driver. Update BIOS & Drivers. As always, it’s a good idea to download and install the latest drivers for your network card. This is especially important if you’re running Windows 8. As for the BIOS, I’ve always been the one to suggest not updating the BIOS unless it’s really needed. However, if you upgraded a computer from Windows XP or Windows 7 to Windows 8 and you tried everything above and updated the driver, then updating the BIOS might be worth it. BIOS is just fine, but there are occasions when it fails and then leaves you with a computer you can’t boot. Only try this as a last resort and make a backup of your computer first just in case. Reset the Router. If you’re getting the Limited Connectivity message, then you can try resetting the router. You can either restart it by just unplugging it, waiting about a minute and then plugging it back in. If that doesn’t work and you’ve tried all the stuff above, go ahead and reset your router. This will reset it to the default settings and will wipe out any security or configuration you had done earlier, so be careful and be ready to do that all again. It’s a last resort measure, but it could fix your problem. Read my previous post on how to reset your router. Remove Anti- Virus or Internet Security Suites. If you have something like AVG Internet Security or Avast or similar software installed on your PC or tablet, then go ahead and uninstall that program and see if your Internet connection starts to work. Many times Internet Security software has been the culprit and you could be pulling your hair out trying to figure out what’s causing the issue, so it’s worth trying. So that’s a lot of stuff to try and practically every sane thing you can try. If none of this worked, then you could possibly have a hardware problem with your wireless card.
