Can Ping but Not Browse

I can ping but I cannot browse.

Ping times seem to be ok, they are in the 65 ms range.  

I am pinging

Other computers on the network and smart TV work ok.

Before I started attempting to troubleshoot this issue it was an intermittent thing.

So today I purchased and installed a new D-Link wireless usb adapter thinking that my old one was just dying a slow death or something.

It worked initially.  I was so happy.  Even got some work done using remote desktop and ie explorer 11 on a windows 7 machine.

After that I fired up my VMWare to get some more work done and it went back to being intermittent and slow and flaky.

I tried doing an ipconfig renew and other tests which all seemed ok.  I uninstalled a bunch of windows updates thinking that they might have been the cause but it only made it worse.

I can't pull up any websites at all.

I uninstalled chrome and found out that you can't uninstall IE.

I restarted the machine and I am currently re-running windows update.

If anyone has a method or a troubleshooting series of steps to help me track down and fix this issue, I would be forever grateful as it is interfering with my work production as it is driving me crazy.

Thanks in advance,

Wireless connections do odd things when they are marginal.  I would first check the connection with a wired network connection before I did any of those other things.  That's always my first test when I have problems with network connections over wireless.

Ping but cannot browse is normally two things:  DNS and/or Firewall.

Check the DNS in your wireless router and wireless connection. If you have a router, ADD to the DNS table in the router WAN connection.

If you do not use a router, but one computer direct connection, ADD into the DNS section of the TCP/IP settings.

In your computer, check your HOSTS file. C:\windows\system32\drivers\etc and make sure all the entries in it are comments.

Also try resetting TCP/IP (do this before adding the DNS entry)

Open cmd.exe with Run as Administrator
Then  netsh int ip reset c:\resetlog.txt
Restart the computer

Remake wireless profiles as needed,

You might also try flushing DNS to check that (again, before adding the DNS entry)

ipconfig /flushdns followed by net stop dnscache followed by net start dnscache

Try these things and please let us know.

DNS should be OK if you're pinging a name and getting it as in "" or "".

I noticed that you mentioned having this problem after bringing back up your VMware virtual machines.  Have you thought about checking the connection settings in the virtual network adapters created when you install a local VMware program (desktop/player)?  It is possible that there is something in your hosts file or dns that is trying to use one of the virtual adapters for your internet traffic which can cause a slow if not stopped traffic speed.  I am not sure but it seems as though you did alot of cleaning and changes to make things appear back to normal and then it all went south again with the start of the VMware program.  I'd check the settings on your virtual adapters as well as any entries that may have been entered into your NAT router or firewall.  Another possibility is that the VMware virtual network adapters on your computer have become the entry point or forwarded port from your firewall which will cause the slow down or even intermittent connections when using your local browser for internet.

I use virtual machines a lot and they do not cause this issue - but there is a always a first time.  I did suggest checking HOSTS earlier.

Thanks for the quick responses all,

My hosts file checks out.  It's all comments.

I turned off my firewall and restarted.  The cable modem's firewall is set to low.

No change.

I did the reset, the flush, and the stop and start ... and restarted.

Could not access a web page.  Tried to ping and got, Ping request could not find host

I waited a few minutes and tried again, this time I got back the four replies and they were right around 177 ms.  Which seems awful slow to me.

Which reminds me, slowness is a symptom.  Sometimes the little rotating circle on IE and chrome spins fast and sometimes it is very slow.

I was able to login to my cable modem and it looks like Dynamic DNS is disabled.
However, I'm not sure if this is where I should try putting in the address anyway. ??

It is not practical for me to connect a cat cable to the back of my cable modem and my signal strength on the wireless connection says it is excellent, however, I think I may be able to reposition the wireless adapter to make it better.  I'm going to try that next.

I'm not sure what, 'remake wireless profiles' means.

Please let me know if you have any more suggestions / things I can try.

I had one client who's wireless signal strength was 'excellent' but he just couldn't get it to work.  It should have been 'excellent', he had two neighbors on the same channel.  As soon as we changed the channel, everything started working just fine.
ajthomas12Author Commented:

That's very interesting.  It somehow makes sense to me, that these could be interfering.  I can see an unsecured xfinity wifi that's on the same channel as me and there are two others as well.  

How does one go about changing the channel?

So I decided to try and back track a bit.

Everything worked for a while, before I started my VM, and after I installed the new D link adapter.

so I pulled out the adapter and uninstalled the D link software.

Then put the disk in and went through the install steps again... it's working.

My google ping times dropped to about 40 ms, which seems more inline with where they were before things started going haywire.

I was also able to open 9 tabs of websites and all worked. said I had download speeds in the 27 Mbps / 6 Mbps range.  Great!

Now the question is, will it last when my neighbors get on their wifi in the morning and / or when I attempt to fire up my work VM again.

I'll fire up my VM when I get a chance tomorrow, if everything is still working that is, and see what happens.

I'll keep you posted.

Some wireless routers claim to 'automatically' select the channel for you but on the Wireless configuration page should be options to choose 'auto' or a specific channel.  Also, if your router and wireless adapter will operate at 5GHZ on Wireless-N, you will likely see less interference.  But maybe not as much range.  That depends on whatever metal objects are inline between the computer and the router.
JohnBusiness Consultant (Owner)Commented:
You might wish to try a different wireless card (USB device) to see if that makes a difference.

Also ask your ISP to reset the cable modem. This means setting up wireless on the modem again.

I opened the work vm today and nothing blew up.  I can connect to web pages both on the VM and on the base machine.  Ping times are still good.


I think the solution was relocating the USB adapter to improve the signal, even though it said my signal strength was excellent this whole time.  

When I backtracked and uninstalled and re-installed the D link usb adapter, I used an extension dock that came with it which moved the adapter 2 feet off the floor and allowed me to point it in the general direction of the cable modem.

So I will award the majority of the points to Dave who stated, "Wireless connections do odd things when they are marginal.", because what was going on was definitely odd.

Thanks to everyone,
