Sorry - think this post was on the wrong forum.  Don't know how to delete it so have copied the content to (hopefully!) the correct forum
 
Sorry - forgot to say also that my computer has a funny IP address (169.254...) which I understand is a Windows default IP when there is a problem

 I was happily browsing the net a couple of evenings ago when suddenly all my sites became unreachable.  On checking the wifi connection it is showing full WiFi connection but with the message 'No Internet access'.

 

My husband's computer is working fine on the same router & network & I have installed a USB WiFi dongle on my machine which is working fine.  So it is not the router.

 

I have searched the net & tried everything I can find but nothing has solved the problem.

 

My machine is running Windows 7 & I have tried (among other things):

 

Re-booting the router

Dis-abling & re-enabling the network adaptor

Updating the drivers

Checking that the IP4 & IP6 are obtaining addresses automatically

Run an IP flush etc etc

 

My computer is also showing an 'odd' IP address (169.254...) which I understand is a Windows default IP for when there is some problem. Reading about the problem it appears that there is some problem with DHCP but no-one seems to be able to tell me how to deal with it.

 

Can anyone here help?

try both an dns flush and a winsock reset  ( ipconfig /flushdns  and  netsh winsock reset )  ; that does the trick quite often.. ;)

Hi

Many thanks but I've already tried these, too.  I have just done them again to be sure... & still nothing :(

 

 I forgot to mention that it also stating 'Unidentified Network' as well as 'No internet access'

Have you tried forcing your machine to forget that network and setting it up again from scratch?   I've had that work when a single machine suddenly just won't connect to the wireless network it's been connecting to flawlessly for an extended period of time.

 

I've also, in the most extreme cases (which have been two over the course of many, many years), reset the router to its defaults and set up a brand new WiFi network.  This presumes, of course, that one has not accepted the WiFi settings that are the default (but it is possible it could work even then.  I never leave SSIDs nor passwords at cryptic defaults; I want something that I or my client will recognize and remember that's not likely to be guessable by an outsider).

Hi Brian.  Very many thanks for this suggestion.  We've got a bit of a busy weekend here so will try this when I get a chance!

Hi Brian.  I've done the above but, sadly, still no go

 

Research has suggested I try releasing & renewing the IP address using the command prompt but when I try this, I get a message saying that it cannot be done while it has some media disconnected.  Haven't a clue what media it's on about....  Any ideas?

Media is the "connection" to the other end of wifi or Ethernet.

 

Look the physical Ethernet port and make sure you have no bent/crossed pins/dust

Try a different  network cable

Try a different lan port in the router

Come up in safe mode with networking and see if networking works

It's a probably a problem with your internet service provider, it happens to me when I don't pay the monthly subscription haha.
