Windows 7: Wired adapter issue

17 Jul 2013   #11

Wired adapter problem

Hi, I finally got some time to re test this. I booted with ethernet attached and saw the same 10-15 sec delay at the welcome to windows screen. So I then disconnected and cold booted a few times over next few hours and saw no delay. On the 25th hour I booted whilst still disconnected and also saw no delay so I then reconnected the ethernet and the delay came back. Keeping ethernet connected I cold booted a couple times a few hours after and saw no delay. So it definetely occurs 24 hours after last boot with ethernet (and not with wifi) - as long as I ensure that I boot within before 1 day has elapsed since last using ethernet I can keep the issue at bay. But this is not ideal. It seems to be some kind of lease issue perhaps. However I am inclined to blame windows 7 rather than my router. I have plenty other devices hard wired to my network and don't see these exhibiting same behaviour. This particular machine has SSD cache drive so it is noticeable due to its fast boot unlike my other laptop.

I tried updating the drivers on the wired adapter and changing the cat5e and cat6 cables I have used but no change. Up until several weeks ago this problem did not exist and there have been no changes on the laptop. The only thing I did have to do was reboot a netgear switch a while back but can't be sure if the problem existed before or after this. In any event I have tried power cycling the router and switch to no effect. If I use wifi I actually use an access point hard wired to the router via the switch and seeing as this causes no delay it rules out the main routers gigabit ports being the culprit. Is there anything I can try on windows - maybe delay the ethernet adapter initialising a tiny bit until windows has at least displayed the desktop or perhaps a way of erasing the local wired connection from windows 7 so that when I reconnect the cable it thinks its a brand new connection and prompts for the network type again. Starting anew might help although I am conscious that I am grabbing at straws a bit.

Well, the whole situation has officially gone over my head. I'm not sure I understand the tendency to blame 7 for the issue though, seeing as it didn't seem to crop up until after a power cycle on your router (switch?). I understand the frustration, though. Using an SSD should make things fly, and as one who boots every morning, I'd never run into the issue. Here's something to try:

Set your machine to a static IP address and setup your router to reserve the IP address for your machine. This will eliminate the DHCP negotiation at boot and could possibly speed things up. I do this with my machine at home. Not for any specific reason, but just to be exclusive. (If there is ANY odd activity on my network, I can eliminate my machine without guessing which IP address I'm at.)

cheers mate. Unfortunately i had already in past static ip'd on windows 7 and also reserved the address on the router and it made no difference. Same outcome after 24 hours. I will try it again though. Totally baffled as you are. I appreciate your efforts though buddy.
