Network / Sharing :: Unknown PC Or Device Detected
Oct 12, 2013
I'm not truly the best with computers, and this is a new pop up for me. I just purchased this new dell laptop in May and have had no problems with it. However, in the last few weeks I've been getting a new pop up in the right hand corner. My house hold have a wireless router that is password protected. I have McAfee Security Center updated, and shows that all my firewalls and security systems are on and active.
However, this is the message I get and I'm concerned about my networks safety:
"Unknown PC or device detected
This PC or device has connected to your network:
IP Adress xxxxxxx"
I've opened my action center to make sure everything is okay, and the only thing I find that isn't turned on is the "Network Access Protection" - which is something I haven't touched before, nor does it provide a link in which to turn it on.

Last part of the message, (Device Descriptor Request Failed). I get this, in Device Manager, and I have searched for an answer on the net. Also it is a Code 43. I went through my laptop, with an HP Technician this morning, I might add at a cost of 5p/minute, for 30 odd minutes. He has said that because I had gone over to Windows 8.1 and the recovery discs I made will not load, to put back in Windows 8. I have to send the laptop back for re-installing the OS, because Windows 8.1 do not have the update for my problem. Also the R.H. USB socket has a failure ID:0GAPTK-6T7716-MFPWWK-8D1Q03. I personally think that this is all what the problem is. a duff USB. Is this a cop-out???
Does Windows 8.1 having driver WHQL problems?
I only found out the problem with the usb when I tried to download a Mobi file to a Kindle for my wife. The other usb's work OK.

First my computer when bought came pre installed with Windows 7. As soon as Windows 8 came out I upgraded to Windows 8. My system is BIOS not UEFI. I have about 3gb ram and 500gb hdd drive 2.20 ghz processor. Windows 8 runs really smoothly. So recently 2-3 days ago I decided to dual boot Ubuntu with Windows 8. Before when I had Windows 7 I dual booted it with Windows 8. So now I thought about dual booting with Ubuntu 12.04 LTS. The Installation process was fine until I take out the installation usb with Ubuntu and whenever I try to restart it the PC would hang on the oem screen for a while which is ridiculously long.
Then when I would boot into Windows 8 and sign in I would get a notification message saying the last storage device you plugged in isn't found. I went to the device manager in Windows and it would say an unknown device has been found and even if I tried to Uninstall it would come back again. I tried searching for updates but nothing came up. I googled it and got no results. What annoys me the most is the PC hanging on the oem screen. Right now I fresh installed Windows 8 so it's the only OS running at the moment. But I want Ubuntu 12.04 LTS because of git, ssh and all the server side stuff. I have also posted the error screenshot for more info.

The cable works on a different computer, the computer gets wireless fine (typing to you from it) but will not read an ethernet cable. The motherboard manual (built the PC myself from components) says an LED should light-up if an ethernet cable is connected, no such LED appears when I connect the cable.

I have a cisco e4200 and after installing Windows 8 RP, I was unable to find the 5GHz band. I am getting 90Mbs on the 2.4 GHz band and I know my 5Ghz band can give me more. The 5 GHz band is detected on my PC before Windows 8 was installed but I can't find it on my PC now. I have two computers who support the 5 GHz band and both can't find it but did with Windows 7. The 2.4 GHz band and 5 GHz band are separately named so that isn't the problem.

I have a Dell XPS 15Z, which I bought off a friend. They recently updated to Windows 8 and so now thats what I have. But when i go into my drivers its telling me that i have an unknown driver. no solutions online have answered my questions though some came close. So, this is what i know:
Unknown Device
Device Type: Other devices
Manufacturer: Unknown
Location: on PCI Express Root Complex
Hardware Ids:
ACPIVEN_SMO&DEV_8800
ACPISMO8800
*SMO8800
i don't know if this is related but my laptop also wont charge. I just bought a new AC Adapter to replace the one i had, and it still isn't charging. The light blinks red 4-5 times and blue/green once. ive searched online to see what the problem is but i cannot do some of the fixes as the computer is at 0% battery.

No USB device seems to be getting detected on my machine when I plug in a flash drive or an external hdd I get the distinctive sound from my speakers that an USB device is plugged in but nothing is showing up in "My Computer". I went through the event logs and found that Windows is failing to load the USB device (check image in attachment logs.jpeg). Recently I installed iTunes, so I though it might be causing this problem but I uninstalled it even then the problem persists. I don't want to format my machine just because of this small problem. Is this a driver conflict ? How do I find out why windows is all of a sudden failing to load the USB devices ? I have uploaded a copy of the saved logs detailing this failure(logs.zip).

I installed Windows 8 in my notebook, Lenovo 3000 G430. It worked fine for a while, but after I had a long shutdown, when reboot again, the Wifi was not working. The drivers are still there, and when activating the Wifi from Fn F5, it goes to Airplane Mode.
I removed Windows 8 and reinstalled Window Vista, the Wifi came back and working fine. I tried this many round, it produced the same result.
I believe that it is compatible issue with the driver for the Wifi. Can some one able to provide the driver for BROADCOM Wireless 802.11g for Windows 8?

I just reinstalled my PC, obviously with windows 8. And I can't seem to play games, i mostly play COD4 and whenever I join a game, I get an Dirextx error, or my PC just reboots..
I don't know if it has something to do with my LPC INTERFACE controller.
LPC One:
on Intel(R) ICH8/ICH8R Family LPC Interface Controller - 2810
The drivers for this device are not installed. (Code 28)
To find a driver for this device, click Update Driver.
Games one:
directx unrecoverable error
And I used to get 'AMD Driver timed out, and succesfully rebooted" something like that.
This is my setup:
OS: Windows 8
MOBO: FOXXCONN p9657aa-8ks2h
CPU: Intel Core2Quad Q6600
RAM: 2GB ddr2
GPU: Club3D Radeon HD 6970 Coolstream Edition
HDD: dont know really, 300gb

Since upgrading my HP DV6T7000-CTO from Windows 7 to Win 8 and now 8.1I have had an intermittent issue where the my wifi/bluetooth adapter is detected, until a restart, and then afterwards, is no longer detected. I have a Intel centrino wireless N 2230 which is both wifi and bluetooth. I cannot connect to wifi, nor is the bluetooth detected. Additionally, the wifi-radio button on my laptop, will not turn on (red is off, white is on). Sometimes I can temporarily fix the issue by shutting down,disconnecting the adapter from my laptop, reseating it, and then rebooting. This does not always work though.
I have tried the latest drivers from Intel as well as tried removing those and just installing whatever Windows update thinks is best. I have also updated the Bios to the latest, but to no avail. I have even replaced the adapter with a new adapter but the same model and that did not fix the issue either.

I have never used 'Bluetooth' before. I want to transfer a file between my laptop and Android tablet. I turned Bluetooth 'on' (which I have installed the latest driver) on my Windows 8.1 laptop. I turned Bluetooth 'on' on my Android 4.1.1 tablet. I had my laptop search for 'Bluetooth' devices, but my tablet is never found. Is there something I am doing wrong?

I'm in Window 8 on a Toshiba L855-S5112 Satellite laptop. It's an inexpensive laptop, which was most likely my first mistake.
But... My wireless sees nothing, and when I check the device manager for the network adapter info, it's enabled and it reports that it's working fine. the wifi switch is definitely set to on. With "show hidden devices" turned on, this is what I see for network adaptors:

I'm a new Windows 8.1 user. Over the past two days two separate unknown network devices have appeared under 'This PC' in Windows Explorer (see screenshot below for the current one, along with its properties window). It appears people are able to access this computer - so a big problem!
As far as I can tell, all my security settings are in place (password on wireless network, all sharing disabled in Network and Sharing Centre, Windows Firewall is active, Windows Media Sharing is off).
How to close what I assume is a security loophole?

Scanning device is an HP Photosmart All in One HP 2575. i first installed it as an USB device and Windows Fax and Scan recognized it and scanned nicely. I then installed it as a network device and WFS would not recognize it as a scanning device when I unplugged the USB cable. It prints just fine but will not scan.

I am trying to share a specific folder on my Windows 8 computer with my Windows 7 computer. They are both on the same network connected to the same router. The Windows 8 computer is connected through ethernet, while the Windows 7 computer is connected wirelessly.
Here are my settings on my Windows 8 Computer:
This is the error I get on my Windows 7 computer:
What's up with this? On a related note, is it possible to share this folder with a specific PC, rather than "Everyone" on the network?

I am having trouble with ICS on win 8. On my old laptop (win xp) I used to be able to share my 3Connect dongle internet to connect to Xbox live. I recently got a new laptop with win 8 and whenever I share this internet connection I can never connect on my Xbox (the network to internet part fails). When everything is connected up and shared the Ethernet says 'Unidentified Network' which i believe is the cause of the problem. I've read i may require a driver update but i cannot seem to find one.
My Laptop: Toshiba Satellite C855-29N
what to do, maybe i am not setting up the connection sharing properly?

I've been trying to set up an old Savin 9033 printer through the company's router, but I couldn't find the network it's set up on from any other computer.
So I pull up Network & Sharing, see that Network Discovery is turned off.
I check it, go to click on "Save Changes" and nothing happens. I click it a few times and it kicks me back to the previous page, nothing saved. No password prompt or anything.
I double checked that all the appropriate services are running (DNS Client, SSDP Discovery, UPnP Device Host, Function Discoveryr Resource Publication, etc.) and made sure Network Discovery was allowed through Windows Firewall.

Is there a way to setup network profiles or something so that when I bring my Surface Pro to work and connect to the wireless network there it will use the static ip address I have but when I disconnect and then connect to my home wifi it will go back to DHCP? On my MacBook Pro I can go into the network settings and change the location profile I have setup for networks but I don't see anything like this for Windows 8.

This morning I installed an optional update from Windows Update. It was Ralink Technology WLAN 802.11 wireless LAN card.
Since then, when I try to print to my wireless network printer, the network would disconnect then come back on after a while. The update shows up in Update History as successfully installed but not in the installed updates. System restore is of no support here. The network configuration page shows normal. The web does not appear to be affected. I made a new network connection for the printer but it did not work.
Is there a way to reverse this update or should I uninstall the 802.11 LAN card and let windows re-install anew.
The printer is a HP Officejet Pro 8600e

When you first connect to a new network Windows 8.1 opens up the following window:
I am trying to automate a way so that the answer is always: yes, turn on sharing and connect to devices.
It needs to be automatic without requiring the user to click on the window. This will be used in systems where no keyboard/screen/mouse are present.

I'm running Windows 8.1 and I have an old version of photoshop elements in my x86 program files (it's elements 4.0). I have UAC on the next to last setting before disabling it altogether. When I launch elements, UAC asks me if I trust it because it's an unknown publisher. I don't want to disable UAC, but I want it to trust elements and not popup the "are you really sure" box each time.
