I can only access the internet in safe mode and not in normal mode.
Safe mode reports I have a home network, while my normal windows 7 pro' reports "Unidentified network" labelled as "work".
Tried loads. Nothing works.
DHCP is enabled in services.
Event Viewer in normal mode reports: "DHCP error ID 1001 0X79
Any help appreciated.
Thank you.
 
Result of ipconfig/all in cmd whilst in safe mode.
Will post ipconfig/all while in normal mode after I have saved it to a file. Have to reboot. Thank you

Normal mode is missing
1) the gateway address
2) the IPv4 address is incorrect

You have a DHCP problem in normal mode

(also note you have IP Routing Enabled while I do not)

OK...
login as admin or runas /user:administrator cmd (and provide the password)
enter these:
  • netsh winsock reset catalog
  • netsh int ipv4 reset reset.log
NOW reboot
 
Followed your advice using cmd as admin but nothing has changed after a reboot.

This is the result of ipconfig/all in normal mode after the reboot.

Still get a different ipv4 address and no gateway address in normal mode as opposed to that in safe mode.!!!!
 
Ok, let's go deeper:

  • netsh int tcp set heuristics disabled
  • netsh int tcp set global autotuninglevel=disabled
  • netsh int tcp set global rss=enabled
  • netsh winsock reset catalog
  • netsh int ipv4 reset reset.log
reboot again

Thank you for that advice Jobeard, and I did follow what you advised in cmd run as admin but has made no difference after rebooting.
I pressed enter between each stage, and it registered as ok.
 
Hmm; how is your LAN described to Network & Sharing? Home or Public?
You're running the windows firewall, right?

Click to expand...

In safe mode LAN is described as Home whereas in normal mode it is shown as "work" and an unidentified network.
Windows Firewall is shown as on in safe mode. In safe mode it is shown as Home or work (private) networks. Public network is not connected.
I'll have to check what it says in normal mode and then get back to you.
 
Windows firewall has the same settings as in safe mode.
I even turned the firewall off and it made no difference!!!

Boot normal
get into Network & Sharing
click on the WORK Network and change it to Home

disconnect the WiFi or the wired connection to the router

Now reconnect whichever and it should return to HOME

After booting normal and going into network and sharing it is just dead and no response, so I can't change it to HOME. Whereas I can do this in safe mode if I wanted to change it.
Already tried rebooting the router after switching it off for a few minutes.

Could this be a driver issue do you think? as we know that safe mode only boots a limited number of them and normal mode boots the remainder.
The network driver is: Realtek PCIe GBE Family Controller 7.101.714.2016 or the latest driver there is.

Have run a full antivirus scan using these separately after installing and uninstalling each of these: Trend Housecall; Avira; Avast; AVG and nothing found.

Something must be corrupted. What do you think? Bear with me as I am a relative novice in these matters.

Have also run sfc/ scannow in cmd which reports no issues

YES, there's a problem TOO MANY AV PRODUCTS. These are being started in Normal mode and not in Safe mode and they fight with each other - - choose ONE. Personally, I' running Avast to scan email and weblinks to avoid getting virus' and trojans downloaded.

Your drivers are fine.

That doesn't solve my problem though. All AV's are now uninstalled as of today.
Any other thoughts on what the problem could be?
 
Back to HOME vs WORK -- there's difference here. Can you set PUBLIC Networking?

Afraid not, and if so I wouldn't know how.

Okay I have set the network to Public in safe mode, and will reboot in normal mode to see if this has any effect.

Nope, no difference. In fact I lost internet connection in safe mode as well so had to resort back to Home network in safe mode to get a connection.
 
Your Firewall is kputz.

What account are you using when booting Normal? Should be a User and not the Admin
