Solved Laptop: some websites don't open via wifi,but work on lan

May 5, 2013 at 23:04:52
Specs: Windows Vista, Intel Core 2 Duo 1.5GHz/ 2 GB
I have a hp laptop which has Windows Vista Home prem, and a desktop with Window XP SP3, both have AVAST.

The Problem.

This started a few weeks, I am unable to access some websites on my laptop which is connected via wifi to my belkin router. The websites are general websites like "businessinsider.com" or " Wiki Answers", some forums, zillow.com but some others like yahoo, youtube, streeteasy, realtor.com work fine. I use Opera browser which displays
the message :
" Could not locate remote server"

Tried the same with Chrome, which displays:

" Unable to access the network"

Error 21 (net::ERR_NETWORK_CHANGED): A network change was detected.

When I hardwire my laptop to the router or while using the desktop which is connected to the router via LAN all the websites work.

I have tried turning off the Web shield and Network shield on the laptop when connected via wifi but no go.

Could really use some help and thank you for taking your time to read through this.

P.S: Please ask if you need additional info,

Hi Gunnarthehunter,

As you mentioned that the website open when internet is hard wired I would suggest you try resetting the router and then try connecting using wireless connection.

Thanks & Regards

Hi Manshu, thanks for replying,

Tried resetting router, no go, on another note, the websites work on my laptop (when using wifi) if I use a proxy server like "hidemyass.com" . Could it be an IP address conflict, been a while since I did some tech stuff. Is there another solution

It shouldn't be an IP address issue. Theoretically, you should be connecting to the same network (your own) whether wired or wireless. Unless of course you're connecting a different wireless network from the wired network.

You wouldn't happen to say, be connecting wirelessly to a neighbors WLAN by mistake would you? Start by double checking to ensure you're connecting to your own WLAN and not someone else's by mistake.

Hi Curt, thanks for replying,

I am sure/checked that I am connecting to my own network and not any other.
Although I erred in mentioning one detail, when I say I hardwired my system, I plugged the broadband cable directly into it without the router and when I do this all the websites work on the laptop. Also the desktop which is usually hardwired to the router (which has the cable plugged in it) displays all the websites. When I hardwire the laptop to the router the problem persists. Not being a prude but these are not any porn/ sensitive websites, they are normal websites like zillow.com, Businessinsder.com, wiki answer pages, some grammar forums (like one in 10 usual websites).

The ip address on the laptop is 192.168.2.3
and the desktop is 192.168.2.5

Please tell if you need any additional info

It is not a browser issue because I tried Opera, Chrome and IE none of them are displaying the websites, however when I use the website "hidemyass.com", it hides your ip, kinda like a proxy the websites open, but that thing is a real pain to use. So could it have something to do with the wireless settings on the laptop ? I cleaned up the system using anti virus , slimcleaner , ccleaner, malwarebytes. these remove any prefetch data too and all the cookies. I also changed the MAC address on the laptop using this software called Technitium mac address changer (an excellent software by Shreyas Zare ) tried turning off the firewall, network shields, web shield no go.

Ok, since it works when the laptop is plugged directly into the modem but not when it's connected to the router via wireless or a network cable that makes me think you have something blocking it on the router or the router keeps getting the same IP from your provider and that's what is blocked.

Here's what I suggest, spoof your laptops MAC address on your router. My reasoning is, when you plug the laptop directly into the router you get a different IP (different MAC address) that isn't blocked.

When you do the ipconfig /all from a command prompt window it will list your "Physical Address", that is your laptop's MAC address. Write it down using a colon between the sets of numbers rather than the dash Microsoft puts in there (the rest of the world separates MAC's with the colon).

Now, unplug your router from your internet feed and log into your router's management interface. Look for a setting that allows you to "spoof" he external (internet side of the router) MAC address of the router. Change that to the MAC of your laptop and power the router off, plug the internet feed back into the router and power it up.

Before you do anything though, do go to "what's my ip" (or any other place like it) and check your external IP address. Make note of it and then once you've finished spoofing your router's external MAC address, check it again. If your spoof is successful, the address should be different. If it is, then try those sites and see if you can't get into them.

Hi Curt,

Whether this issue gets resolved or not, I really appreciate your help.

Okay here is what I did in a step wise manner:

1) First I went to what's my ip and made a note of my external IP address.

2) I did an ipconfig /all and made a note of my Wireless Network Connection's physical address (no hyphens).

3) I hardwired the laptop to the router, it is a Belkin and there is an option in it which says ' clone your mac address to the router ', when I selected that the router picked up the ethernet MAC address of the laptop on to the router, but we were looking to clone the Wireless MAC address onto the router, I manually changed the router address to the Wireless MAC address.

4) Unplugged the internet feed and applied the changes in step 3.

5) Then unhooked the laptop from the router, shut down the laptop, powered off the router.

6) Hooked the internet feed back to the router, powered the router up.Powered the laptop back on and connected to the internet via wifi from the router,

7) The websites are still not working but computing.net and other sites work.

8) Some other steps I tried earlier, flushed the DNS, tried changing the MTU settings then changed them back to the original when that didn't work.

9) The IP address which I get when I powered on is different from earlier.

Go back, redo step 3 and let the Belkin router clone your laptop's wired network interface. If I'm not mistaken, that's the interface you're using when you connect the modem directly to the laptop. Therefore that's the MAC address you should be cloning.

Sorry, I should have thought to mention that to you in my last response.

Give that a try and report back.

Hi Curt,
Glad you are still here,

So here is what I did,

1) I redid from step 1 onwards, except at 3 when the laptop was hardwired to the router,
I just hit the 'clone' button on the router settings, it picked up the mac address of the ethernet card, so now the router has the same mac address as the local area connection (ethernet) on the laptop.

2) Powered off, powered on but the websites aren't working(wired or wireless), also it gave me a different external IP address from step 1.

3) I was able to deduce some things from this, the broadband cable is working fine, because when I plug it in directly to my laptop or my desktop everything works. Now my desktop ( XP sp3, avast, ) which is usually hardwired to the router (the broadband cable goes to the router) works fine, that is everything opens up in the desktop. However when I hardwire the laptop to the router or when it is connected wirelessly the websites don't work. The browsers are fine too, so the issue is with the network settings on my laptop or the settings on the router ( not that these are small areas!!)

4) I know we can beat this man, please sleep on it for a while.

Thanks again, will wait for your reply.

4 = LOL

What we now know thanks to your extensive troubleshooting:

1) Your desktop can access all websites when plugged into the router.

2) The laptop can access all websites when plugged directly into the modem

3) The laptop can't access certain websites when plugged into the router but can access other websites

4) Cloning the laptops MAC onto the router did not make a difference in the laptops ability to access said websites when it was plugged into the router.

Conclusions:

The issue must be within the laptop itself.

Other client computers plugged into the router behave correctly. If other computers exhibited the same behavior as the laptop, it might be the router. Also, since the laptop can access some websites without issue, the laptop's TCP/IP settings must be correct. To check the TCP/IP settings, open a command prompt window on the laptop and on the desktop when both are connected to the network and run the ipconfig /all command on both and compare.

The only setting that should be different is the actual IP address of each computer. The subnet mask, default gateway and DNS addresses should all be the same. If this is not true, post the output of both (appropriately titled) and we'll have a look.

Assuming the TCP/IP settings for both are indeed correct, the only thing I can suggest at this point is to check and see if the built in windows firewall is enabled on the laptop. If it is, try disabling it and see if you can't access those websites after doing so.

Hi Curt,

So here is what I did,

The present setup: Desktop is hardwired to the router, the laptop is connected via wifi to the router.

I ran an ipconfig /all on both the systems, the observations :

1) Both have the same external IP address.

2)The systems have different mac addreses, and the router has the mac of the laptop ethernet.

3) Both the systems have the same :
Connection specific DNS suffix
Subnet mask, default gateway. DHCP server,

4) The IP address on the laptop reads 192.168.2.4 <Preferred> and on the desktop it is 192.168.2.5

5) The DNS servers on the dekstop are 4 lines of digits on the laptop it is just one line which is 192.168.2.1 (same as the default gateway and DHCP server)

6) I will try turning the firewall and antivirus of for a few min's and check.

7) Turning off the the firewall and anti virus didn't help.

Reporting back,

So I bought a friends laptop, and connected via wifi to my network.

The websites don't open up in her laptop either, even mozilla.org doesn't open. It works the same way as my laptop.

I am thinking we are back at the routers network settings, I am going to try resetting it, Belkin also gives you a Router monitor software, I had it a one time I will try reinstalling it and get back.

This tells me you likely have a DNS address (or two) manually configured on the desktop and that's why it's working. When the DNS address given out by DHCP doesn't work, it tries the others listed in it's table and one of those is correct.

At this point, I suspect the best thing you can do is reset the router to factory defaults and then reconfigure it. It would appear the router has something misconfigured between it's LAN and WAN side. By default, it should have a route between the two sides and it appears that it doesn't or the DNS would work.

When you reset the router, do so with it plugged into the internet. As soon as it's rebooted, connect your laptop to the router with a cable (into a LAN port) and let it get it's TCP/IP settings and then try browsing the web. If it works, problem solved.

Hi Curt,

Just before I read your note, I reset the router to the factory settings, I reset it in a few ways, I first restored it to the factory settings from the router homepage, both from the desktop and the laptop too, still no go, the websites don't come up.I reset it manually using the switch (tried this in a few iterations with the router disconnected from everything except power , with it hardwired to the the laptop(no cable) , etc,) no go,

I pushed the reset switch on the router, while it was still connected to the cable broadband, power, held it for 10 seconds, tried to reconfigure the router by installing the Belkin Router monitor (tried this a few times).

But here is the funny part, even though I reset the router a couple of times, it reconfigures itself; this is a bit a tricky let me explain,
The Confession:
Originally when I first setup the Belkin router I installed the Belkin Router monitor along with it, it is a software which comes with the router. My cable internet works this way you can plug in the cable to a system, and you need to enter a user id and password (given by the isp) in any browser window to log onto the internet, however when I put in the router the Belkin set up monitor took the the id and pass during installation so I didn't have to enter it every time. So once the laptop/desktop were on, they would be connected to the internet. And then for some reason I decided I didn't want this router monitor thing running on my system (I don't even know why, probably the little green thing was annoying me, the silly things I think of and do) , so I kicked it out ( uninstalled it with revo uninstaller-nice soft), well after uninstalling the router was hardwired to the desktop and I could connect wirelessly to the router, that is to say everything appeared fine minus the belkin monitor, I didn't notice the issue at that time.

I think the id and pass are kind of welded into the router settings, because I still don't have to enter them when connected via the router (hardwired or wirelessly), but if I unplug the cable from the router and plug the cable into the laptop it asks for the id and pass.

The Present:

Even though I reset it a couple of times (factory reset and switch reset) , within a couple of seconds after resetting I am able to go online without having to reconfigure the router. Even the Belkin router monitor which I tried installing doesn't take the user id and pass, says they are invalid (they are correct, I rechecked), but midway through the setup I am already online, so I guess it doesn't need them again. Hmmmm , just explaining all this makes me think about the age old maxim "If it ain't broke, don't fix it" , boy is that true or what.

I wouldn't do a "flushdns" on the desktop unless you've written down it's DNS addresses. Chances are they're manually entered so flushdns wouldn't do anything to them but there's no point at this time to bother.

From the sounds of it, your router may be broken. If you can get another, even borrow one to test, I would. If it works ok, replace the belkin.

Dear Curt,

I finally solved the issue, :)

I chatted with a Belkin tech support agent.
She made me do the reset again, but it was not the reset which resolved the issue,

First about the reset/restore:

1)I unplugged all the cables except the power from the router

2) Held the reset button for 30 seconds.

3) Switched off the power supply to the router.

4) Powered it back on after a few minutes.

5)Connected it to the laptop.

6) Went to the router homepage 192.168.2.1

7) In the homepage of the router, under " Connection type". I choose Dynamic.

This is what I did differently, when I plug in the modem cable into the router, it automatically chose pppoe setting in lieu of the dynamic, although I tried changing it to dynamic in a previous try, that didn't work as it took up the pppoe again, but this time I plugged in the broadband cable at the last min, immediately selected dynamic and applied changes, probably that did it along with the reset.


Finally I am able to view all the websites on my laptop and desktop, didn't have to install the Belkin monitor. The agent mentioned something about the router being in passing (stg about it being frozen), but now it is working splendidly.


Thank you again, for staying with me on this and also thank you RamyaSu (Belkin tech agent) for your help.

Really happy guys.
