Cannot Browse Internet from Desktop Computers Using Verizon DSL

Helping a non-profit client who has been having connectivity issues during the past week or so.

They have Verizon DSL high speed access w/ a statically assigned IP address. They have a Netgear Wireless N ADSL2+ Modem Router DGN2000.

Odd thing is that the wireless access is just fine. However, all three desktops that connect via ethernet cable are having intermittent problems.

The desktop I'm sitting in front of (running Windows XP Pro SP3) is plugged in via Ethernet but cannot access the internet. The system tray shows that it has a 100Mbps connection, but no access to the internet

When I type in a URL in Internet Explorer, the lower left status bar says "Website found. Waiting for reply" but then just sits there forever and never connects, but also never gives an error message.

Firefox says "Waiting for google.com" for about 15 seconds before getting an "Address Not Found" message.

Pinging out to yahoo.com from the command prompt sometimes and other times just gives "Request Timed Out" message. It's inconsistent.

The Netgear Wireless router is not using the default UID & PW  and I don't have that info so I cannot log into it view settings. Yes, I could do a hard reset to factory settings but that may break the wifi connectivity, which I don't want to do.

I have attached ipconfig /all results below.

I desperately need some guidance as to how I can resolve this. Thanks in advance.

Are the machines by any odd chance set to use a Proxy (alot of recent rogue malwares do this)....

IE>Tools>Options>Connections>LAN Settings.
No, no proxy set.
Try flipping a desktop to DHCP as well, and renew an address....
requested info from acl-puzz would be helpful
Thanks Guys. Gotta run. Just outputted results of the tracerts to usb stick. Will post them in the next hour.

Where are the Desktops connected to?  Wireless Router or another Router on the Network?
ok and also check if any bad program running kill their process  download process explorer

http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx

 and remove an weird entry there you see in autoruns download from here

http://technet.microsoft.com/en-us/sysinternals/bb963902.aspx

 Download Comboxfix and malwarebytes to scan system drive some malicious programs can do this also

http://www.combofix.org/download.php

http://download.cnet.com/Malwarebytes-Anti-Malware/3000-8022_4-10804572.html

do report back!



According to your ipconfig output the desktop systems are set to static IP assignment. The DHCP server might be assigning those same IPs the the wireless clients. Without being able to log into the router its hard to tell the ip range. Do the desktops require a static ip?
CP. The desktop I was working on was connected via ethernet cable into the back of the Netgear wireless router.

The other 2 desktops are on a different floor via a cable that connects down to another non-wifi router.

Thank you very much to everyone who has made suggestions so far! I will be at the client site at 11am EST to implement your suggestions. I will post a follow-up as soon as I am able.
Ran Malware Bytes and removed some spyware infections on the desktop PC. Was still unable to go online.

I ran "netsh int ip reset resetlog.txt" and then rebooted. Now the system tray shows the status of the local area connection as "limited or no connectivity." Click on "Repair Local Area Connection" option but got following error message:
"Windows could not finish repairing the problem b/c the following action cannot be completed: Renewing your IP address."

Going to try running ComboFix next.
While you at it run a scan with Hitmanpro
http://www.surfright.nl/en/hitmanpro

Can you post Mbam's and Combofix's logfiles
"Now the system tray shows the status of the local area connection as "limited or no connectivity."

simply open lan properties and uncheck the box says "Notify me when this computer have limited connectivity"

""Windows could not finish repairing the problem b/c the following action cannot be completed: Renewing your IP address."


that means it did not get ip from DHCP server issue these command

ipconfig /release

ipconfig /renew

if you got infection then i hope after removing those you shold get internet working

do report back!

Running ipconfig /renew at command prompt resulted in following message:
"An error occurred while renewing interface local area connection : unable to contact your DHCP server. Request has timed out."

Yes, lights on the router and the back of the NIC are light up and blinking.

Found the Admin PW for the router.
are others machines on network getting ip?

is dhcp client service on this pc is enabled? if not goto run type services.msc and select  this service and start it if it is disabled

also restart Network Connections service there
Did you try changing the Link Speed and Duplex from Auto to a fixed value yet?
Yes, DHCP client is enabled on this desktop.

Yes, I tried changing Link Speed and Duplex from Auto to a fixed value and didn't help. :-(
Other odd thing is that this desktop PC doesn't seem to see the router b/c I cannot log on to the Admin Panel on the router from this PC.

From my MacBook connecting wirelessly, I simply type in 192.168.1.1 and I get prompted to log in and can access the router info.

When I type in 192.168.1.1 into Firefox on the desktop PC, I get a "Failed to Connect" message.

Just spoke to Verizon tech support but they weren't much help. Said it must be an issue w/ Netgear router (which is not their standard config) so they want me to call Netgear support.
others machines on network getting ip? can you check that? is this an single machine here?
"When I type in 192.168.1.1 into Firefox on the desktop PC, I get a "Failed to Connect" message."

becoz you havent get ip  from DHCP server yet as told by you previously

try using static ip like this 192.168.1.250 and all settings manually

Every machine using Wifi (3 PC laptops and 2 MacBooks) are absolutely fine.

This XP Desktop that I'm sitting at on the 3rd Fl (connected via Ethernet cable) and 2 other PC desktops on 1st Fl (also connected via Ethernet cable) are not connecting.

I will need to run some tests from the desktops on the 1st Fl.
try using static ip like this 192.168.1.250 and all settings manually like dns, gateway
I put in a static IP assignment on this 3rd Fl PC and now I'm at least able to ping out yahoo.com as well as 192.168.1.1, but still getting about 25% loss on the packets.

I don't understand this!! How can Wifi connections be 100% OK and the wired connections be such a disaster? Everything is working off the same router.
are you able to get internet back on this pc where u have problem? are able to browse websites?
No, not at all. No internet access whatsoever on this desktop PC.
ok use alternate web browsers  i mean you may use Chrome Mozilla Opera see if internet works with them or not

but i believe if port 80 is blocked on gateway which is yours router you can not browse internet check in router is port 80 is blocked for this pc using its hostname

to check yours name issue this command in cmd

hostname

now you need to check if port 80 is blocked on router for this

uroboros1200, I'm afraid you may be correct. I just called Netgear support and they acknowledge that this is a know problem with DGN2000 units manufactured in the early part of 2009.

They are offering to send me a replacement unit for $29.

I just find it bizarre that it would work OK for many months and now it stops working, but only on the wired connections??
may i know you if u tried what i suggested in comment id 30050401 ?
hostname on desktop PC resulted in:
mcc-office-new

Will check router to see if this hostname ID is blocked.
Some other posts seemed to point to heat related problems. I read that the replacement units shipped with stands to keep them vertical for proper ventilation. Unfortunately i also read many of the replacement units also failed. Are they replacing it with another DGN2000?

$29 is a good price but not if you have to service it again in a few months.
and if u still have same ip what it was previously also check by ip
Yeah, I assume they will replace w/ the same model.
I'm not sure where hostnames would be blocked in the Netgear settings. Below is screenshot of the Firewall settings.

As a temporary fix you can try switching the cables to different ports as one or two may still work.
I tried different ports and no good. Think they're all toast.

I downloaded & installed Opera browser, but still can't connect to internet.
Sorry... Good luck with the replacement.
We received the replacement unit (same exact model) and now everything is working just fine.

Sincere thanks to everyone who contributed to this posting!!
Thank you! It was a damaged device after all and had to be replaced.
You're welcome :)
