Hi

 

The power supply failed on our router and as I only needed the one laptop connection; the connection to the router for my network was unplugged and put straight into the modem, I have two laptops, an old HP nx6110 and a lenovo g580 that will not connect to this network but worked ok before with the router included.

 

I am trying to figure out why the lenov won't work with just the modem connection. Tried the usual things like turn off and on, run ipconfig /release and renew. Tried the onboard diagnostic that say the the local area network doesn't have a valid ip address and when I hover over the network icon it says unidentified network.

 

I did used to get the ip address confict when more than one laptop was connected but I just used to run ipconfig /release and renew. Whether this is in relation to the problem i have now I do not know but it may provide a clue as to the current state of the network.

 

Strange thing is the old HP laptop works ok on the network.

 

Thanks for any useful tips/help

 

Andrew

The problem might be due to a static ip was set from the LAN card IPv4 properties which range is from the faulty router. Try using auto IP address by LAN by reading this http://windows.microsoft.com/en-ph/windows7/change-tcp-ip-settings'>link. If nothing changes, try resetting the modem and connect by wired again.

Both ipv4 and 6 are apipa, I tried manually setting ip/subnet to no avail. The connection specific dns suffix is missing when I run ipconfig, when I ran ipconfig on my lenovo there are 4 sections coming up:

Ethernet adapter local area connection:
===============================

Connection specific dns suffix       .........
Link local ipv6 address                 xx.xx.xxx.xx
ipv4 address                                 xx.xx.xxx.xx
subnet mask                                 xx.xx.xxx.xx
default gateway                            xx.xx.xxx.xx

Tunnel adapter isatap.(xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx)
==============================================

media state                                 media disconnected
connection specific dns suffix     ..........

tunnel adapter 6t04 adapter:
=======================

connection specific dns suffix     ..........
ipv6 address                               xxxx:xxxx:xxxx:xxxx:xxxx
default gateway                          ..........

tunnel adapter terodo tunneling pseudo-interface
=======================================

media state                                media disconnected
connection specific dns suffix     ..........

Using a working computer and a flash drive to transfer the software to run and paste the logs on your next reply,

Download MiniToolBox and open/run the program.
When open, checkmark or select all options then click Go.
A notepad will open then copy-paste the report on your next reply
