Win 7 network IP addresses out of range & more
Posted on 2013-10-29
Hi, questions at bottom - first describe problems....
I have one of my Home Group machines saying it has an IP address conflict (another with same address of 192.168.137.1) although I can not see anything else with that address, and on checking the Event System logs (5 critical events are attached) it says there is an address out of range 169.254.173.92 - I can not understand why this address has come into use. Also critical logs saying it can not configure IPV6 stack.
I think this problem is a continuation of the last question "Win 7 system time out of sync". The fix found then to enable ICS in the 'Sharing' tab of the network adaptor was superficial fix that did not answer the underlying problem.
This machine 'Asus V' had Win 7 re-installed 2 weeks ago after a Win 7 update contained one update that Msoft have now flagged as a faulty update - see my earlier ExpEx question. So, with a re-built clean registry and network, how is it generating IP addresses so far out of the usual addresses.
My adsl line is connected to a Virgin SuperHub which is set to modem only. It connects to an Asus RT-N66U wireless router. All machines are Win 7 and wireless connected. But, to get them to recognise each other after installing the Asus router last w/end, I had to cable connect them to the router as well.
My main machine 'Asus J' is always cable connected as well as wireless. Each machine's 'Network & Sharing Centre' shows Home Network with the Wireless connection. Each also shows 'Unidentified Network-Public' on the Local Area Connection (which would be the cable connection) but, with NO Internet access.
Surely it should show internet access - the router it connects to gives that access.
Why is it unidentified ? I tried using the 'Local Group Policy Editor' to set unidentified to Private on the Asus V machine, but, on reboot it returned to unidentified.
Why is it always a Public access, if I click the Public icon, it does not give any option to select any network name.
If I click the 'Merge or delete locations', it only shows one.
On viewing the network map in the router, my main machine IP address is now 192.168.1.210, earlier this year it was the usual 192.168..1.1 . Somewhere all IP addresses used are being reserved and each set-up is issuing the next one up. It is in a mess. Is it best to delete all networks at root level on all machines and start fresh.
(one thread I read said that Win 7 sometimes accumulates ghost IP addresses causing conflicts - is this the basic problem ???)
How do I delete and reset all network and IP's ??? ...... 2 days ago I did a netsh winsock, and IPV4 and IPV6 reset following an Msoft solution.
If so, I can then assign fixed IP addresses to each machine in the router - they were in the previous router, but, address numbers are so illogical now, it needs sorting first.
