Windows 7 64 bit very slow after adding Netgear 3700 router
« on: October 08, 2012, 10:21:41 pm »

A bit off topic, was thinking somebody might know.  I recently got a Netgear 3700 wireless router. My Internet access feeds into the router via eithernet cable and and the router to my main PC also via eithernet. Prior to adding a router Windows 7 took about 2 minutes to fully boot from a cold start. Now it takes almost twice as long. I leave the router on all the time. Anyone have any idea why Windows now takes so long to finish the boot? I'm assuming this is NOT normal.

A couple of guesses:

  - bad port switch or cable (check Window's Ethernet error stats for the NIC)
  - fluke hardware pairing issue (update drivers for both the Netgear and your NIC)
  - DHCP timeout, dropping to local-link autoconfiguration
  - the configured DNS servers are not responding, or are slow to respond (be sure you've configured the fastest DNS server as your primary, and remove any that don't respond)

  - DHCP timeout, dropping to local-link autoconfiguration

I would put my money on this one. If a Windows PC is configured to get its IP address from a DHCP server, it will try a few times to do so; and then if there is no response (after about 60 seconds) it falls back to assigning itself an AutoIP. (Note AutoIP addresses are in the range 169.x.x.x so checking your IP using IpConfig is a dead giveaway that the PC is using AutoIP...)

That adapter error could be from a duplicate IP address on the LAN (How are you assigning the IP addresses?).  You'll have to look at the error messages that preceded this one. 

Or it could be worse.

Are you experiencing other random issues/crashes?  If so, it is time to start considering you have some bad hardware such as memory.

Been an adventure, spent the last 45 minutes on phone with Netgear. They walked me through about a half a dozen changes in advanced settings. I had two different DNS showing, why/how who knows. Under Netgear's Genie app it always showed WiFi connect not enabled, now it goes back and forth between not enabled and enabled without me touching anything.

It does show the 6 devices on the network under Network map. While making all these changes it showed it constantly installing the attached devices in a seperate little window at the bottom of Windows desktop, then said they were ok, only to repeat the process about a dozen times in a loop. I rebooted the router, at least that stopped that nonsense. I'll see what if anything happens.

I always let the IP address assign themselves, don't see any duplicate.

This may or may not apply to you (I have a different Netgear router), but my money is on the Genie app (the actual app not the browser interface) as the cause of problems. It installs/runs a daemon at boot which may cause problems for other apps or for network in general. If you have it - uninstall it and see what happens. If you computer explodes in a million rainbows it's not my fault.
