Just got my lappy back, new motherboard, new OS install, all good....

But I cant seem to connect my Wifi anymore???

I had a problem previously, where my lappy was no longer picking up my wireless connection  automatically, as it did when new...so I asked the techies to fix that when in for repairs recently, and they did, and say it connects to thier wireless network, so all good...

The Wifi is now picked up automatically, which is good, but I cant get a proper connection, just 'limited or no connectivity'

I have a d-link g604t and toshiba satellite m40
have dhcp enabled on router and 'obtain an ip/dns address automatically' selected on lappy
have channel 11 selected on both router and lappy
have windows firewall and avg antivirus

signal strength = excellent
speed = 54mb


if i go to 'repair' the connection, it will come back with the following error:

'Windows could not finish repairing the problem because the following action cannot be completed:
'renewing your ip address'

in the network connection details box, it reads:

physical address: xxxxxxxxxxx
ip address: xxx.254.xxx.185
subnet mask: 255.255.0.0
default gateway:
dns server:
wins server:


Now thats not right....this lappy should have a local ip address, eg 10.1.1.4, and the default gateway should be 10.1.1.1
But should not having the dhcp server on do that automatically?
I never had this problem before

Please someone help!
