Internet connected but cannot connect

[ichicat]

Hello,
I joined the forum just to address my concern.
My HP laptop 2006 model was upgraded to windows 7 from vista 1 year ago.
It was working great then suddenly early this year, I cannot connect to the internet.
I thought it was my ISP problem. I called my internet provider and opted for dual connection, LAN and wireless. Still no access.

I reformatted my laptop last sunday, wipe all data clean and then install everything back again, my kaspersky internet security and office. all worked fine until 2 days the internet went off again.

More weird things, I can use skype and bittorrent. I can also update kaspersky but firefox and IE cant browse.

I tried turning firewall off and downloaded the trial version of sphinx software "windows 7 firewall control". It did solve the problem for 1 day but failed again.

Im frustrated by now. I went to hp service center and told me my laptop wasn't compatible with windows7 and should only use vista. I think that's unlikely the cause.

Any help is greatly appreciated.
Jim

I remove bonjour using bonjour remover.exe but no bonjour found in my laptop. I tried to ping google.com from run but server not found.
I also tried typing IP address in IE but cannot access.

But to my suprise, I can use internet now in FF and IE by typing this thread.

Im not gonna put [SOLVED] on this thread yet because I feel not secure.

More infos to come.

If you boot into safe mode with Internet, do you have full Internet access?
What is it you presently cannot access?
Can you ping an ip address?
Can you ping an alpha address?
Do all browsers work, or just some?
Did you scan for malware and viruses?
Did you power down/power up your router?
What if all firewalls are off (JUST for experimentation)?
In your IP settings, are ip and dns set to auto?
Provide a screen capture of ipconfig /all at the command prompt.

So busy I haven't use my laptop for the whole week.

@Lemur
The problem of my laptop is that I can connect the net since I can use skype and bittorrent.
I cannot use my internet browser(firefox and IE) due to " page not found" thing.
I haven't tried using safe mode in accessing the net.
I tried "pinging" google using ip address and google.com in cmd but failed.
I don't know what's alpha address.. what is it?
I scan many times using CCleaner and my laptop is doing well, no malware/viruses so far. Also, my Kaspersky Internet Security is doing great with less than 1 yr in license to go.
I did power up/down my router while rebooting my laptop.
My Windows 7 firewall is OFF since I downloaded and use the trial version of Windows 7 Firewall Control Software.
Yes, dns and ip are set in auto.
I read various post nearly identical with my situation and tried "netsh winsock reset" and "netsh int ip reset" thing and was successful in resetting but still no internet.
I also tried ipconfig/flushdns as what other threads say.
I have no bonjour mdsresponder in my laptop as verified by bonjour remover tool.
Im using wireless connection.
My ISP provider software says Im connected to their modem, to their network but not to internet.

I will post screeenshot next time. Im using my friend's laptop.
Im thinking could it be kaspersky blocking me? My kaspersky was trouble free since I bought it last year.
There could be something else.

What happens if you type 173.194.36.104 into your web browser (google's IP address)

 

[ichicat]

Page error or page not found in both IE and Firefox.

Additional info.
When I ran network troubleshooter, it cannot resolve the problem.
Same with my ISP software troubleshooter, cannot solve the problem.

I think something is blocking my internet most probably a software or deep within win7.

Did Network Troubleshooter give you any sort of clue as to what was wrong? Mine is normally very helpful, and tells me if I'm having a router error.

The fact that you can get online at all, suggests that it's not your computer thats at fault, but in order to check it, try booting into "Safe Mode with Networking" and see what happens.

To be honest, I'm thinking one of two things:
1) The Modem/Router is dying, and not resolving http properly.
2) Its a problem with your ISP.

couple of things I notice that seem a bit suspect:

I called my internet provider and opted for dual connection, LAN and wireless. Still no access.

have you tried using LAN only? Possibly Windows is getting confused.

My ISP provider software says Im connected to their modem, to their network but not to internet.

Do your ISP say you are connected to their network? (not the software, the actual ISP) If so, then it is most likely their problem.

another thing that might be useful, is if you open command prompt and type "ipconfig /all" (no quotes) and post a screenshot

Do you have another computer you can test the connection on?

The fact that you can get online at all, suggests that it's not your computer thats at fault...

Im using a laptop from a friend.

The built-in troubleshooter couldn't resolve the problem and will direct me to microsoft community for more help.

What I mean with my ISP software is that in normal internet mode, my laptop will connect to their modem/router, to their network and then to the internet.
They do have an animation where I can see the error.
I did experience before where I only able to connect to the router but not to their network and the ISP guys couldn't ping me.
Now that I can't connect to the internet only, they told me they can ping me.

Ok I will use LAN when I get home. I will also post ipconfig/all screenshot next time.
I have to go.

There are complaints about Kapersky causing connection problems all over the internet. Some said that doing this works to fix the problem...

Ok, do the following:

Close the apps that you are having problems with.

Open Kaspersky
Go to Settings > Click Firewall > Under filtration System click Settings.

Under the tab "Rules for Applications" delete the following:

iexplore.exe
firefox.exe
MSN messengers and Yahoo messengers exe's

Restart ie or firefox and see if you can get a web page.

Thanks chev.

I reformat my laptop last night. I freshly install win7 by dawn and tried internet using the built in IE. Still no internet. I use LAN and Wireless. No internet.

I called my ISP and they assist me this whole afternoon. They told me that they only give dynamic IP address to all their residential users. I can opt for a static ip thou.

Now let's dissect the problem.
1. I have fresh win7 with no other software installed. No internet connection in LAN and wireless.
2. I cannot ping my modem using LAN but I can ping using wireless.
3. Sometimes I can access the net for 10 seconds on random reboot of my laptop then goes back to nothing.

With the scenario above, Im having thoughts that maybe the HP guys are correct that my laptop isn't compatible with win7. I should revert back to Vista as its original OS.

Now.
1. Is it really my laptop's incompatibility with win7 causing the problem?
2. My HP laptop is 2006 model pavilion dv6000 series.
3. The original built in Vista was flawless despite slow processing speed.
4. After getting rid of vista and installing win7 about a year ago, my internet connection started to deteriorate starting from LAN until I couldn't connect using wireless.

If you guys support this theory about my laptop's incompatibility, I will surely revert back to Vista.

For the ipconfig/all screenshot, please see attached.

Here is a guide for your model of HP with drivers, you should follow the guide and install the drivers. It looks like HP does not support your model but this guide should get it working for you. There looks to be two different links, one for AMD and one for Intel.

Your gateway address looks strange. If you are not able to ping ip's I would blame the default gateway.

If you cannot ping domain names I would look to dns servers.

The fact that you cannot ping your gateway is a LAN issue and must be solved before you attempt to fix the internet.

Your routers dhcp server could also be causing the problems.

thanks nickiler.

@chev, im looking on the hp website now. There are lots of support in there and I do find my laptop model dv6550ee. Thanks.

I reformatted my laptop again this morning and installed my old XP OS. Still I cannot connect to the net using LAN and wireless.
I think its my ISP provider problem. There could be a wire problem somewhere out there. I also notice that my laptop was sending already but doesn't receive anything save for a few burst in a second then nothing receive again.

Im also thinking that maybe a hardware issue in my laptop(ie, my network card malfunctioning). But that's unlikely..

Since XP doesn't solve my internet problem, I can say that win7 is not at fault afterall.

Gonna post some updates soon.

I'm curious and if your still unconnected you can try setting a static.

Set as your address:
192.168.1.10 or 192.168.0.10

Subnet:
255.255.255.0

Gateway address:
192.168.1.1 or 192.168.0.1

Try to get the dns servers for your isp and use those for the dns or use the router.
192.168.1.1 or 192.168.0.1

Sometimes just setting a static can bypass some problems.

Hi nickiler,

I solved my problem before reading your post. But let me recap what's happening in my laptop.

1. I lost my internet connection before in windows7. I reformatted, installed windows 7 again and still no internet connection. I reformatted and installed windows xp still no luck. I resorted to install win7 no matter having internet connections or not.
Windows 7 is not at fault.

2. Having fresh windows 7 installed, I manage to install skype from USB drive. I was able to use skype but my IE and Firefox browser still no connection. I observed that IPV4 and IPV6 displayed "no internet access" but when skype is running, IPV4 will say "internet connected". Im not an IT guy but I can say something's wrong with IPV6. Note that Im using wireless in this connection, not LAN.
My hardware wireless networking card is functioning well.

3. Since no software installed in my laptop other that skype, there could be no suspect in blocking my internet access. I turn OFF windows firewall and still no internet access in browser but Skype is OK.
Windows 7 firewall is not blocking my internet access.

4. With this current scenario, I tried pinging my router in cmd and was successful. I tried pinging google using "google.com" and using its IP address to no avail.
My laptop connection to my router is good.

5. I tried the following in cmd "netsh winsock reset" and "netsh int ip reset" many times and reboot but still no internet connection.
No winsock related problem in my laptop.

6. I tried giving static DNS server using 208.67.222.222 in my wireless IPV4 and viola!.. I have internet access in my IE and firefox browser.

I installed my kaspersky and waited to update and internet was super excellent. I reboot my router and my laptop many times to be sure of my internet access and it was really really working.
Giving static DNS server address in my IPV4 solved the problem.

Now, Im not an IT guy but I have questions. I solved my internet connectivity in wireless mode. Do I need to set static DNS server in IPV6 also? Because in my wireless status now, IPV6 still shows "no internet access".

Im gonna resolve LAN issue this weekend. Im satisfied by the status of my wireless connection right now..

@ Nickiler,
Im gonna try your idea this weekend. Im quite busy this week.

Much appreciated,
Jim

 

[nickiler]

Glad your problem is resolved. Try setting the static dns settings in the routers DHCP server.

If your router allows it your clients will automatically obtain the network settings from the DHCP.

I have 200+ workstations setup like this.
