Can connect to router but not to internet?

I recently tested Vista on my PC. My parents really liked it and asked me to
upgrade their PC to vista as well. I did so and everything went ok, except
for one thing: the wireless connection.

My PC connects directly to the router via ethernet, but my parent's PC
connects VIA wireless USB adapter. Everything is set correctly, but for some
reason it connects only to the router but not the internet. In the network
center, it shows a valid errorless connection from their PC to the router,
but an error from the router to the internet. Yesterday, I was able to
somehow connect for 10 minutes, and had the internet working, but then it
disconnected again. I have been tinkering with the settings for over 3 days
and don't know what to do anymore.

Does anybody have any clue how this issue can be resolved?

Hi,
I had the same problem when trying to connect wirelessly to my network
through my router. After searching around I found that you need to go -
Tools, internet options, in the drop down box that comes up, click on"
Internet" in the window box and UNCHECK the box in the lower left corner that
says ENABLE PROTECTED MODE. Click apply and close out of the open boxes.
Doulble click Internet Explorer icon to load up and you should be okay, You
will have to click on the HOME button every time you load up I.E. as it
prompts you to do this if you want to connect to the internet. Worked for me
after trying everything else. Don't know if this is a glitch in the OS or a
security feature. Hope they disable this check box by default in later builds
or Microsoft will be swamped with calls with people trying to connect to the
internet.

I have a similar problem except mine says its connected to the internet but
when i diagnose the connection it says Domain name server not reachable and
plug in adapter in local area 5?
I dont understand as i'm not using lac 5.
I unchecked the boxes as stated earlier but no joy.
I can connected to skype, or play Counter strike online and use xfire i just
cannot use the internet for browsing?
I'm using a wireless connection that works perfectly in xp. (on a different
hard drive)
Any help would be most welcome

I've got exactly the same problem as John:

Seems to connect to my wireless network, but then says "Local connection".
If I go to properties, then IPv4 is Local, and IPv6 is Not connected. The end
result is that I can't do anything with my connection at all - no Net, can't
see other PCs on the network, nothing.

I'm using a D-Link DWL-G520+ with XP drivers, as D-Link don't have any Vista
ones yet.

I have basicly the same problem. I am using the 64-bit version of the Vista
public beta and can see the machines on my LAN but cannot hit the internet. I
can even browse to the web page on my D-Link router but cannot get to the
other side. The internet works fine for the other machine of the network and
on this machine under XP. I have verified my network settings and they all
look OK. The Protected mode checkbox seemed to have not effect.

Microsoft is aware of trouble in the following areas:

1) On a wired network, being able to talk to the local network, but having
no access to the network. You may be able to ping an internet host, but you
will not be able to connect to it.

Please go to the manufacturer of your router's website (from another
computer obviously ;) and download the latest firmware update, and follow
their directions on installing it ... this may fix the problem.

This problem is related to your router not properly handling internet
traffic.

2) Wireless network connectivity

Updating your driver may fix any connectivity problems you may have.

If you can connect to the internet thru a wired connection, try checking
Windows Update for an updated driver. Also, try your computer manufacturer's
website and the wireless network card manufacturer's website.

Also, if you are able to connect to the internet somehow, you should report
the problem with the problem reporting tool, which you can access from the
Feedback link on the desktop.

1) On a wired network, being able to talk to the local network, but having
no access to the NETWORK

should read

1) On a wired network, being able to talk to the local network, but having
no access to the INTERNET

Darn newsreader ... changing my words .... ;)

For a wired router, if:

- You have full access to your local network
- You can ping internet sites, such as www.google.com
- You cannot access the internet

This is indicative of a problem with the way the router handles Window
Scaling. This is a new feature in Vista that allows your network to
automatically "tune" itself to get the best network performance.

For more information on this feature, follow this link:
http://blogs.msdn.com/wndp/archive/2...g_tcpip_2.aspx

Now, even though this is a new feature in Vista, Window Scaling is part of
the standards that these router manufacturers are supposed to adhere to.

Unfortunately, since not many OS's do alot of things with Window Scaling,
some routers will not handle it correctly. I'm sorry you are having bad luck
finding a good one.

I wish I could be more helpful, but I can only tell you what Microsoft has
said. Which is, that they are reading your posts in the newsgroups and
debugging the problem.

- They are going to do everything they can to get this feature to work with
all routers, if they can.
- Download the latest firmware for your routers
- If Microsoft comes up with a solution to this problem on their end, they
will distribute the fix as a Windows Update. So, if you can directly connect
your box to the internet every now and then to download Windows Updates, you
should.

Ok you all had some decent ideas... except for a few which made me wonder if they were just random responses...

I have had the same problem with a client's computer, can connect to LAN computers and even look them up by DNS name, but can't ping any internet DNS names while other computers on the network could.

I tried EVERYTHING on EVERY ARTICLE ABOUT THIS.

Heres what just solved it for me:
In Local Area Connection Properties, right below Internet Protocol Version 4 there are two other items - "Link-Layer Topology Discovery Mapper I/O Driver" and "Link-Layer Topology Discovery Responder". I unchecked them both, hit OK, and voila.

Had nothing to do with hardware. Vista Sucks.

This has happened to me twice, both times after I introduced new Vista machines onto my network. (Environment is Vista -> Linksys Router -> Comcast)

I don't know what causes it, but I do know what I did to fix it.

1. Go to Device Manager
2. Find the Network Adapter
3. Uninstall it (but keep the drivers)
4. Scan for hardware changes

The card will be "rediscovered" and magically, Internet access returns.

Again, something got weird, and needed to be wiped out. I don't know if this will work for you, but it worked for me.

I also figured out that you have to disable the firewall when you do this, or else you get an "Unknown Network" in addition to your "Private Network". Whenever you see "Unknown Network", just know that your Internet connection probably won't work.

I had a similar problem recently where an XP network was running fine with both ethernet and wireless connections.

I added a new Vista laptop via it's wireless connection and got "limited accessibility". (ie. it could see the router but not connect to the internet.)

Now I know this laptop was configured OK to run on an XP network because I had set it up the week before to run on this guy's home network....and it was fine.

The problem turned out to be the Router which was an oldish model that needed a firmware upgrade before it would allow the Vista laptop to connect fully in wireless mode.

So I suggest that before you tear anymore hair out, you run the model number and firmware version past the router manufacturer's tech support to make sure that it's Vista wireless compatible........might save you many more hours of frustration.

That may be your solution......but it wasn't mine.

Until I get a network working correctly I never enable encription. I had this problem even though there was no network encription.

I think you will find that this problem doesn't have just one solution, but can be caused by a number of factors.....so, all the solutions offered here should be checked because any one of them could be the answer.

ok boys... here is the solution....

The problem is Windows Vista Home Premium does not know how to connect
to wireless networks using the WEP Key...

If you Disable Wireless Security (i.e. No WEP Key)... and try to
connect to your router.... you will have LOCAL AND INTERNET
connection... and your Vista Home Premium connects to the internet
wirelessly...

The minute you put WEP security back on..... Vista cannot understand it
anymore... and your connection to the internet is cut off....

YES!!... THIS IS A VISTA PROBLEM.... nothing else....

And the people at Microsoft DO NOT KNOW HOW TO FIX IT YET!!!

Oh Wow!! This is a great bit to absorb or even try testing for someone lacking the computer know how of those here. I'm running Vista and attempting to connect via a public network. I'm connected to the network but cannot access the internet. A friend sitting right beside running XP on her laptop connects to the same network without any problem at all!

This is a problem that only presents itself when attempting to access a public connection. I have a wireless network set up in my home through which I have no problems getting online. I fear adjusting many settings may create a problem with my home network as well.

Any suggestions would be greatly appreciated,
Thanks...

Can you ping a public IP address like 4.2.2.1? If yes, can you ping a web
site like chicagotech.net?

hi everyone, i am having exactly the same problem as what people have described on here and have tried all the suggestions that people have put forward but no joy. i dont understand it because in all the other houses ive lived in the wireless has always connected but now that ive moved into my new house it wont connect and just says local connection. ive even tried to connect with an ethernet cable and after some fiddling around it worked but by doing this, it must have affected the wireless as my housemates computer couldnt pick up wireless then, yet i could pick up the net through the cable. Im starting to think that its the router that is rubbish and wanted to know what other people thought?would it worth buying a new router and seeing if that worked?thanks any answers would be greatly appreciated.i have no idea about computer, which youve probably already guessed by this message so yep any help would be ace!thanks Anna
