Vista renames my network to Network name "2"

[HasserCasser]

Hi

I have a Zepto Nox A14 with Windows Vista Ultimate 64Bit.

I have a Wireless network named "Fungus". I can easily connect to the network but recently it has started to rename itself to "Fungus 2" on my PC.
The people I live with have no problems connecting to the network.
I have restarted the router + modem, did not work.
I have removed and reinstalled all my network drivers, did not work.
Disabled IPv6, did not work

When running an IPconfig/all it looks like this:
IP-address: 10.252.22.105 - Should be 168.192.1.*
Default gateway: 10.252.16.1 - Should be 168.192.1.1
DHCP: 89.101.160.36 - should be 89.101.160.4
DNS: 89.101.160.36 and 89.101.160.37 - 89.101.160.4 and 89.101.160.5

The problem solves itself after a couple of days, but it is quite a nuisance to have to use a cable, when there is a wireless connection present.

I hope you can help me out. Thanks in advance
