Ive been using a netgear DGN2000 adsl modem/router for about 6 months now with no issue.
Lately i found that on bootup both my vista64 machines would report that no cable was plugged in on the network properties. The relevant port light on the router just flashed once every few seconds.
If i powered off the router for about 5 mins and turned it back on it would then work. I tested the router with my xp laptop and no such issue occured.
The problem now is all the time, the router simply wont negotiate with the vista pcs at all.
I recently switched BB from zen to O2 and have found that the o2III box works fine with both the vista pcs!.
After a bit of searching i found a few articles suggesting that the vista DHCP is incompatible with some routers, and that there is a registry fix to turn a flag off. I have tried this and it has not worked.

So to summarise, the 2 pcs work fine on the o2 router... meaning the network cards work. The netgear router works fine on the xp laptop ( all ports ) meaning that also works. So logic suggests the problem is with vista. The fact it has happened on 2 pcs of different spec and NIC brands suggests that its an update thats buggered something.
Any suggestions? ive tried reinstalling the NIC drivers, applying the registry fix and so on, to no avail. I have also tried setting the pcs manually ( ips ) but i still get the "no cable attached" situation.
