Greetings-- 



I, too, have had various networking problems win Win7.  I've set myself up to use NAT for my 'household network' and have recently had problems with my ISP.. While they "seem" tyo be cured for now, I don't trust the situation. 



After a situation where I could not send any email with an attachment, I contacted my ISP, and they were also less than helpful.  What is working for me now is an older version of my NIC drivers, reinstalled with the "repair" option checked.  As you try to trobleshoot this, do the usual "power down all modems, routers, switches, etc. ., power them up in the appropriate order, and then re-try your connection.  (The problem I had is that I did exactly that and still had the problem, even after isolating the modem by re-routing the cables and making my 'one' computer the only connected device.  Needless to say, no problem was detected.)  After re-establishing my LAN (assigned computer addresses, gateway (router), and etc., everything worked fine.  I suspect something was "done" at the ISP end, but can't prove it.  The only thing I did do that seemed to have an effect was to either reinstall my NIC drivers  with the repair option checked, and installing the previous version of the NIC drivers.  In any case, if you have a NIC built into the motherboard, download several versions of its driver, and experiment with those until you find one that provides reliable connectivity. 



Best I can do with a confusing problem that also afflicted me...

Subject: [PCBUILD] Win7 Ultimate can't connect to sires 

  I have a Dell Optiplex 960 desktop, about 18 months old.  A vieus 
rendered its hard drive unbootable, so I used the restore disks I had 
made to rewrite the OS partition.  I've reinstalled all the drivers and 
applications I can find. 

There is a gigabit NIC on the motherboard, and a second installed as a 
factory option -- one has a BroadCom chip and the other seems to take an 
Intel driver.   
  Last night, I hooked up my ASIX AX88772 USB-to-Ethernet adaptor and 
installed its drivers, freshly downloaded, but I have the same problem 
with it. 

  Whichever of these three NICs I use, I get the same results.  The 
machine receives a DHCP address assignment from my router, and I can 
ping the router, Google (resolved using DNS), and a router on campus 
seven miles away across the Internet.  And everything works fine if I 
reboot into Ubuntu Linux, so I'm confident that the hardware all works. 

  The problem is specific to Windows 7 (this is the 32-bit "ultimate" 
version).  Neither IE (reloaded with the OS, which means it's not up to 
date) nor Firefox (11.0, downloaded about 2 weeks ago) can ever connect 
to a web page -- not even the web page of my router, which means it's 
not an ISP issue.  Automatic Update and antivirus updates say they are 
looking for updates, and don't report any error -- they just never find 
them.  (IE sometimes reports that it "cannot display the web page", but 
is unable to offer any helpful hints why not.) 


  Can anyone else suggest something I should check or try?
