my PC does not frequently detect my WIFI network on the WIFI list, although it is detectable on my phone. So still suffer from this problem which does not allow me to connect to my PC.

Description of my network card
First of all, i should try to use Solve problems tool on windows. Sometimes solves problems.
If this doesnt work, check your drivers and if none of this options work, i would to replce your network card.

I recently acquired a Bluetooth headset (Philips SHB9100) for my smartphone, but also wanted to use it with my Windows 7 PC, so I bought a cheap USB Bluetooth adapter without noticing it was a v2.0 adapter, while the headset is v2.1 + EDR.
The USB Adapter installed correctly on Windows 7, and I am able to discover my headset, but when they try to pair, an ugly Error 0x80004005 appears, never asking me for a PIN.
After some googling, and founding many people had this pairing problem, I read that the major improvement in Bluetooth v2.1 is SSP, which permits pairing without the need to enter a PIN, and also that Windows 7 chooses the "best pairing mechanism" automatically. And so I started to suspect that this is what's happening:
Windows discovers a SSP capable device.
Windows tries to pair with that device using SSP.
The USB Adapter, being v2.0, is unable to permit pairing with the headset via SSP.
Windows does it's best showing a 0x80004005 error.
I searched for a v2.1 or superior USB Bluetooth Adapter in my city but couldn't find any (I'm from La Plata, Argentina) and even though I think I'll end buying one, I'd like to make this work, or at least know for sure why the devices aren't pairing.
And so my question is (and I swear I did some more googling before asking here):
Can I force Windows to try a legacy pairing with my headset?
Any info on the subject is welcome.
Thanks!
I recently faced a similar issue and after a lot of trial and error together with research, I finally fint a compatible driver. I downloaded a few drivers from the intel site and tried it with each one of them. Finally I was able to fix my issues with the driver below.

A few useful pieces of information: I'm running Windows 8 Professional on a custom-built rig, and I am using a 'WiFi dongle' to connect my computer to the local router. I am using a home network, not a public/work/school network.
I installed the Windows Phone SDK. Piece of strawberry cheesecake so far. Coded my first simple browser app (as detailed on the Windows Phone Dev site) and hit the Run button, expecting my app to come to life and breathe in links and breathe out websites!
But instead, I got this:
Something happened while creating a switch:
Xde couldn't find an IPv4 address for the host machine.
In this case, the emulator wouldn't run at all. And so, I did my research and found out that the solution was this:
Remove all the switches from Hyper-V Manager's "Virtual Switch Manager", and make a new Internal one called Windows Phone Emulator Internal Switch.
I did, and the error did NOT show up again but it did screw up my WiFi and Bluetooth adapters (which I had to do a system restore to solve) and now both WiFi and Bluetooth peripherals are working again.
However, I got this error instead when running the emulator again:
The Windows Phone Emulator wasn't able to connect to the Windows
Phone operating system:
The emulator couldn't determine the host IP address, which is used to
communicate with the guest virtual machine.
Some functionality may be disabled.
In this case, the emulator did run, but I couldn't find my app anywhere. I did some research again and found that the solution to this was:
Delete the Windows Phone Emulator Internal Switch from Hyper-V Manager's Virtual Switch Manager.
Now, I created the switch to solve the problem in the first place. But I did delete it, for the heck of trying everything out. And no surprise there but, it went back to the first error.
I am now stuck in this paradox and have no idea how to escape it.
Thank you in advance!
follow the following steps to solve this problem
1.go to network and sharing center
2.go to change adapter setting
3.go to v Ethernet (internal Ethernet port windows phone emulator internal switch)
4.right click it and enable it(if already enabled then disable and enable it again).
Remove any Cisco VPN's or similar connections. I have found this VPN client works as a replacement to Cisco https://www.shrew.net/
For me shrew soft version 2.1.7 was the only version that worked.
I have this one issue, which I'm hopeful you guys will help me out with...
I use a plugin we have created for IE... It detects devices over the network... Devices are the ones that we ourselves have created... Now this plugin works fine and detects devices when it is wired with the Ethernet on our Subnet in XP as well as Windows 7... It detects devices when it is connected Wirelessly over our Subnet in Windows XP... But when I connect it with my Wireless subnet over Windows 7 it stops discovering the devices... The moment I enable my LAN it again detects the devices... It's behaves very stange on this part and I can't be sure that Windows 7 is responsible for this but it had to be considered... There seems like a wireless security affecting it but there is no such proof as off now...
I'm not fully aware of the plugin code but it uses mDNSresponder service over the network...
I use Windows 7 64-bit OS and Internet Explorer 9... The tests have been made over Windows 7 32-bit and IE version 8 and 9, to give the same outcome... Windows firewall has been turned on/off as well...
I'm sorry if I've posted over a wrong thread, please forgive me for any inconsistencies... Any help is appreciated... Thanks...
EDIT-1: The plugin has been built with C++ and I could give you the code for it as well but the point is that it does not get involved here... It seems like an issue over Wireless in Windows 7... I used Wireshark to sniff the packets over the network and found out that there while running in a wired network I can see requests and responses over the MDNS protocol... But when I switch to Wireless network there is no request or response over MDNS and hence there is no query sent only over the network... Seems like when I connect with the Wireless network, something blocks the plugin from querying the network... Help me out with this if possible... Thanks so much...
Ok the issue is solved... The problem was that my program was not being able to find the IEEE 802.11 wireless network interface... Since the dawn of Vista, Windows has changed some it its architecture and my program was made years before that...
Before Vista, the network adapter type value for Ethernet and IEEE wireless was same i.e 6 and is known as MIB_IF_TYPE_ETHERNET... But now they both have been differentiated and IEEE wireless adapter gets a new value 71 named IF_TYPE_IEEE80211... In our code we had a validation to reject network adapters other than MIB_IF_TYPE_ETHERNET and so it used to work with XP, but Windows 7 had other plans... Adding another validation for IF_TYPE_IEEE80211 solved the problem.

i want to Debug some Networkproblem cases in my Application. But i can't really test it because my Phone has internet over USB. If I disconnect it from USB i can't debug... So is there anyway, I can disable the Tethering over USB on my Phone?
Edit: I have a HTC Trophy but it's the same with the Lumia 800 of my friend...
Assuming that you're connecting to a web service which isn't running on your machine, you can test this by disconnecting your PC from any network which gives it access to the internet (i.e. turn off wifi on the pc or pull the network cable.)
It's not an elegant solution or one that can be easily automated but it works. ;) (I used this method with testing an app which would progressively download large files in pieces and would stop and then resume as connectivity was lost and restored.)
You also can use Fiddler http://www.fiddler2.com/fiddler2/ as a Proxy for your emulator to simulate lossy connections or no connection at all. This way you can still surf and look for references while you code :-)
edit: fiddler doesnt seem to work for the Emulator(for more information, look into the comments), but if you want to simulate a lossy Connection then this is the way to go, even work for phones with the connection-cable.
I've been trying write an application which will be able to connect to a network device via rndis or over wifi and perform some simple operations.
The kicker is that I want to be able to find a device I've connected to before, through either connection method. I initially figured I'd just check for a previously seen mac address, but I discovered that the rndis mac address and the wifi mac address don't match. I'm on windows so the next thing I tried was to use nbtstat -A and ping -a, but those didn't turn up anything unique either (I figured I might get a device name, but it doesn't seem to have one).
So my question is, is there any tool (ideally available for windows), which will allow me to retrieve some sort of unique information about a network device that will allow me to find it again? I don't have a huge amount of experience in this field so I'm not sure exactly what that would be, but I hoped that there may be a way to get the mac addresses for both network adapters while only connected to one, or perhaps use a different tool to find a device name that I'd missed.
Thank you for any advice you might give, I really appreciate it. Sorry if I'm overly wordy.
EDIT: In case I've been ambiguous. I am connecting repeatedly to an external device via RNDIS or WIFI from my desktop PC. My goal is to be able to consistently recognize the network device regardless of the connection method used.
EDIT: By networked device, I mean that I have small independant devices (such as cell phones or tablets) running a unix os, which I access from my Windows desktop via wifi or rndis, and that I would like to be able to consistently identify. So for example I might want to use this tool to connect to one of two cell phones and be able to recognize which one it is so I can recall previous operations performed with that device. So what I'm looking for is a unique (or semi unique) attribute of the cellphone available to me that is consistent when accessed via rndis or wifi.
You can get MAC address (and bunch of other network interface info) with built-in ipconfig command and parse its output later:
ipconfig /all
Alternatively, if MAC address is all you need, try getmac.
