Windows 7: Unable to Achieve any Network Connectivity, Wireless or Wired.

05 Jan 2016   #1

Windows 7 64 Bit Professional
Unable to Achieve any Network Connectivity, Wireless or Wired.


I returned from Vacation today to find that my work PC is not able to network at all. I usually use a cabled connection, this was not recognised by windows (however the lights on the network card were flashing as normal).

I then gave up and tried to install a wireless dongle (as I thought there was an issue with the networking port on the motherboard). The driver for the wireless dongle is installed correctly, and it is operating correctly according to device manager, however it's not possible to activate the menu to select a network from the taskbar.

The icon showing on the taskbar is just the normal computer symbol with red-x. If you right click and go to network and sharing center, it's not possible to get to the adapter settings (the system tries but it times out). It ends up on the Network and Sharing center screen, with "Unknown" next to the networking symbol. There is also the message "The dependency service does not exist or has been marked for deletion". Neither the wired NIC or the wireless dongle are visible here at all.

I've tried the things I normally would (re-installing drivers for the wireless dongle, enabling and disabling the network adapters) but nothing seems to change.

Does anyone have any advice on some steps I could try?

I would uninstall the adapters and their drivers from Device Manager. reboot. If the adapters are not auto-installed do it manually.

You could also try Safe Mode with networking.

To really test for a hardware problem - which doesn't seem likely since both adapters are involved - you could run Linux live from a DVD or a USB stick.

Also, reboot the router.

Internet connectivity problem, affects wired internet but not wireless
I am having Internet connectivity issues that only affect my computer and only affect it when I'm using a wired connection as opposed to a wireless connection. I would just use the wireless except that it's too weak here at my house especially in the room where I'm working and thus it's slow...

Netgear DGN1000SP connectivity (wireless and wired)
And the time has once again arrived for me to ask for help. Starting around a week ago I began to have problems connecting to my router via wifi; after turning my laptop on I would simply have "No Internet Access" and could remedy this by toggling the in-built adapter. Then that stopped...

Wired vs Wireless network, is wireless safe.
I generally don't have a need to network computers together. In fact if I do network in my home it will be for only one purpose and would prefer to have the network down 99.99% of the time. I can run the lines needed to connect these two computers but wireless would be easier to get going. I...

Hey, Bit of an odd one here. I work at a company in the UK which is attempting to start rolling out Windows 7 to all computers (early adopters and all that, it's just a lot easier than the current mishmash of OSes we have!). One of the 4 users migrated so far is having an odd issue with her...
