Problem connecting to internet only at startup

[bardos]

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.

Any security software running? I have dd-wrt 2.4 sp2 running on my router. I have several machines in my network, but recently introduced a Win7 laptop into this network. This is the ONLY machine that presented me with the type of issue you're talking about. After a lot of searching about updating drivers, and just about everything else mentioned...I thought my Win 7 laptop had some corrupted files. I have a ghost image of laptop with every app. configured EXCEPT for the security suite software. As soon as I blasted this image back onto my laptop...everything smoked....my web surfing was incredibly fast...and I have QoS enabled through dd-wrt, so I can have torrent, emule downloading at the same time while, like I said, my web surfing smokes!!!, on my Win7 laptop. I tried several security suites, and then finally settled in BitDender 2010, on the Win7 laptop...and everything's been working flawlessly.

That is a good point Mysterio, I'm not even sure if the Op has even had his connection up and running long enough to download anything.

yes, downloading all sorts of stuff. lol.

well,the latest: you know when you set up a new OS there is tons to do and tons to reinstall etc. my last reboot, after a myriad of whirling dervish like installs and configs had the network working like God intended.

All is well atm according to my last reboot, the first time that i have gained internet access at boot. and the sad part is, obviously, that i have no clue what i did right.

needless to say, i have just backed this current setup as an image. the world is good.

happy new year.
