Problem connecting to internet only at startup

With winxp i booted into my desktop and i had internet. Now, with same static IP connection as always, I boot into the win7 desktop and i have no internet access.

To get internet access i have to either disable and enable the connection, or uninstall the network card at device manager and then it will be found again. Once found or re-enabled i do have internet access. anyone have any ideas?


Motherboard: gigabyte p35 d3sl

Control Panel > Network and Internet > On the left-Change adapter Settings > select your LAN > Properties > TCP/IPv4 > Properties

Is your machine set to obtain IP address and DNS server automatically?

oh yes, absolutely. also in device manager everything looks fine even at startup.no yellow exclamation marks.

Ipv6 connectivity is "no network access"

I'm sure you have already tried the Gigabyte site or Windows update for your Windows 7 mobo drivers.
GIGABYTE - Support&Download - Motherboard - Driver - GA-P35-DS3R (rev. 2.1)

Are you using a router or connected directly to the modem?

You could try to renew the IP lease by using the commands on the page below.

i downloaded and installed the most recent lan drivers for my motherboard v2.0 and the strange thing was that on reboot I had internet access according to the tray icon, something which had not ocurred before at bootup. everything on paper was great, but there was no genuine connection to surf or download mail etc. so i did a rollback to the former drivers which is also a win7.sys file and i had instant internet. so i'm stumped.

Are you using a router? Firmware updates may be required.

i have just updated the NIC drivers again and not rebooted. connection is fine for the moment. router is linksys wrt54GL running DD-WRT v23 SP1 Final

I was about to mention you should try installing those drivers again because it seems to be the only thing that has made a difference.

You could try it connected directly to the modem and see what happens, that would eliminate the router which is only compatible with 32 bit systems by the way. See this in the link below.

Are you using Windows 7 64 or 32 bit?

well, using the new drivers once again, i rebooted and had the same results, now. that is, i disable and enable and then i have internet.
using 32 bit windows7 ultimate.

You should try to connect directly to the modem and see if anything changes.
