Default gateway problem

[Tedium]

This might be answered in the 'Vista assigns 0.0.0.0. IP address' thread, but
that was a bit technical so I couldn't follow it.

I have an intermittant problem with my internet connection at work. Well,
not so much intermittant as near constant, I fail to connect 90% of the time,
following no pattern I can identify. I've tried rebooting, disabling and
enabling the network adapter, and followed all the advice that the
troubleshooter offers to no avail. My ip/config all when my connection is
functioning is

Host Name . . . . . . . . . . . . : Toms_PC
Primary Dns Suffix . . . . . . . :
Node Type . . . . . . . . . . . . : Hybrid
IP Routing Enabled. . . . . . . . : No
WINS Proxy Enabled. . . . . . . . : No

Wireless LAN adapter Wireless Network Connection:

Media State . . . . . . . . . . . : Media disconnected
Connection-specific DNS Suffix . :
Description . . . . . . . . . . . : Atheros AR5005G Wireless Network
Adapter
Physical Address. . . . . . . . . : 00-19-7D-6A-E2-19
DHCP Enabled. . . . . . . . . . . : Yes
Autoconfiguration Enabled . . . . : Yes

Ethernet adapter Work:

Connection-specific DNS Suffix . :

Physical Address. . . . . . . . . : 00-16-D3-51-82-41
DHCP Enabled. . . . . . . . . . . : Yes
Autoconfiguration Enabled . . . . : Yes
IPv4 Address. . . . . . . . . . . : 172.16.240.66(Preferred)
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 172.16.240.254
DNS Servers . . . . . . . . . . . : 192.168.100.254
NetBIOS over Tcpip. . . . . . . . : Enabled





When it is not working there is only one small change,

Ethernet adapter Work:
Default Gateway . . . . . . . . . : 172.16.240.254

becomes

Ethernet adapter Work:
Default Gateway . . . . . . . . . : 0.0.0.0
172.16.240.254






Thanks in advance for help/advice,

Tom
