Solved Windows 8.1 loses wired internet connection

[JHouse]

I had this issue also'after update of windows 8.1. My wifi was working but couldn't use an internet connection via a cable ethernet. I resolved using the following:
1. Right hand side edge swipe
2. In the 'search'area write 'device manager'
3. select 'Network Adapters'
4. Select your ethernet connection device (mine was Realtek GBE Family Connector)
5. Select 'Uninstall' the device
6. Select 'OK'to confirm uninstall.
7. Restart my desktop. This installs the device driver again automatically. My wired connection shows up and is working.
8. Also... Right side edge swipe
9. Select the 'settings' icon
10. Select the network icon on bottom right hand side
11. Select my wifi connection
12. Un-select the option 'connect automatically'

Lastly the HP helpdesk (awesome group by the way), had me uninstall my wifi adapter and restart. This is to ensure I had the latest driver for my wifi.

After this all working well!

I have the same Realtek PCle Fe Family Controller. Tried all this, and it didn't work. As a matter of fact, it made the frequency of losing the connection increase. So I right clicked to update the driver and now it is back to "normal". On and off, on and off, on and off.............

@JHouse,

Rolling back to an older driver seems to be the solution to this problem. Best bet would be to search with Realtek and find a driver that is one version ahead or behind of the one you have installed now.

Found this on another site:

My adapter was set to auto negotiate the speed by default (it is burried away in Ethernet Properties / Configure / Advanced tab and Speed & Duplex property). Since changing this to "100 Mbps Full Duplex" a month or two ago I haven't seen a dropout again.

Would it be possible to get a little more detail as to how to do this?

right click the network icon in the taskbar and click on open network and sharing center
click on change adapter settings
right click your ethernet icon and click properties
Click configure, then click advanced tab, then click speed and duplex and change the value

Mother of GOD! I thinks it's fixed. If you were a beautiful single woman who wouldn't talk to my wife I would hunt you down and kiss you on the lips. Thanks Guys. This is HUGE.

Well, it's back. No explanation. The settings remained the same. So how do I switch back to Windows 7 that I "upgraded" to 8.1? I don't want to pay for it again.

 

[Dude]

Before you switch back, try a system restore to a date where it worked.

Solved!

SOLVED! I have a Broadcom Netlink (TM) Gigabit Ethernet card in a Dell Studio XPS 8100 and ran in to this problem after upgrading from 8 to 8.1 yesterday evening; I was getting ready to do a Macrium system restore, but ended up doing the following:

1. I tried CalBear's solution above: I visited Dell's website and downloaded the the older driver (12.4.0.3, dated 10/16/2009). I installed it, and the connection worked just fine.

2. However, after a little more research at Dell (using the link CalBear pointed out above: Broadcom NetLink Ethernet Adapter issues with Windows 8.1 - Desktop General Hardware Forum - Desktop - Dell Community), I discovered that Broadcom updated their driver in July 2013. The new driver version is: 15.6.0.10, dated 7/26/2013; I downloaded and installed their new driver and I'm 'up-and-running!'

For you Broadcom folks, here's the link:

Good luck!

Before doing anything drastic--Device Manager / Network adapters / {your network card} / Power Management. Uncheck "Allow the computer to turn off this device to save power."

Thank you. This resolved my issue. I was dropping internet as well. I would ping the default gateway and would get a huge fail rate. Before I tried this fix, I would have to unplug the ethernet cord and plug it back in so that it would reset. Now with this setting, it works amazingly well. Not disconnects.

Man what a mess..

Do you have a firewall on? Have you messed with any firewall rules??

I would just backup all your files you want to keep and clean fresh install windows 8.1 if you have your key..

Thanks Dude.

right click the network icon in the taskbar and click on open network and sharing center
click on change adapter settings
right click your ethernet icon and click properties
Click configure, then click advanced tab, then click speed and duplex and change the value

It seems to be so simple, yet it's worked for the past 2 hours. No disconnects -- yet. It was driving me mad.

I recently changed to Avast internet Security and started to experience frequent DNS connection drop out problems so I thought I would try the solution offered by ActionFlash (#26).
Using https://www.whatsmydns.net/dns/ I looked up my ISP (Optusnet) DNS server address and reconfigured my connection as advised.

I have no more problems, thank you.
