Hi there!

From what I've been seeing and been doing my research for the past two days, many people have been having the same issues throughout the years, however, this is the first time I've encountered this issue and many of the specific workarounds or fixes have not worked for me. I've been trying to work through this for 24 hours straight now, but to no avail so many thanks to those that can help.

On Monday night, got home from work; surfing the internet for half an hour, everything was fine as always. Just after half an hour, my Internet got very sluggish and then it died completely. I thought it might have been the an update I just put through in terms of Windows Update that said was a critical update for MSE, as the same thing happened a few years ago. I did a System Restore to two different dates that were in the past two weeks, nothing.

Uninstalled MSE and disabled Windows Defender and the Windows Firewall: Nothing.

Reset IE Options, Reset Winsock, Dumping DNS, many of the other command prompt screens to reset items: Nothing.

Reset the modem: Nothing.

What DID work, however, was a ping test to Yahoo. The ping test worked, saying all four packets was recieved, yet nothing else popped up. LAN and CenturyLink said everything worked on their end and that everything was connected properly, as well as the speeds working fine.

CenturyLink said in their notes that they thought Port 80 was blocked. I went and put in the Firewall to allow Port 80 but it didn't make any difference whatsoever.

I remembered I had a spare modem laying around and I switched them up, both modem and the cords - nothing.

I then hooked it up to my netbook to see if that would work, as it usually does - connection didn't work there either.

Like I said, it's been about 24 hours now and this is increasingly frustrating, as I've tried all solutions (While browsing through 10 search results pages on my phone) suggested and still nothing.

Any suggestions and tricks would be greatly appreciated!

Here's my specs:

Windows 7 32-bit Home Premium
Intel Core 2 Duo 3.14 Ghz
4 GB Kingston DDR2 RAM
eVGA nForce 750i SLI
eVGA GeForce GTX 560 Ti FPB
ISP: CenturyLink
No router
Modem: CenturyLink 660 Series

PLEASE NOTE: This is the only computer I have (Like I said, the netbook solution didn't work), so downloading programs and such is not an option til I get to other computers somewhere else, like right now. Unless someone knows of a way of copying/pasting a file in Windows and then transferring said info to an Android smartphone, this is gunna take a while haha. Patience is requested.

In IE, Tools, Internet Options, Connections, LAN Settings, then uncheck all boxes and OK. Close IE and restart IE.

In FireFox, (Tools or the Firefox button), Options, Advanced, Settings, check No Proxy then OK. Close Firefox and restart Firefox.

In Chrome, Wrench, Options, Under the Hood, Change Proxy Settings, uncheck all boxes, OK.

Any better? No? then:


Start, All Programs, Accessories, right click on Command Prompt and Run as Administrator, Continue. Type with an Enter after each line:

net start dhcp

net start bfe

net start tcpip

net start afd

net start nsiproxy

net start bits

Which ones say they cannot start? Now do:

nslookup  att.com

It should look like this:

Non-authoritative answer:

Does it?

None of the above solutions worked. When I entered it into CMD, it all said that the requested has already been started.

I did get exactly the same results bout the att.com part though.

[t3techcom18]

The only difference was that the last two lines aren't the same numbers:

144.160.36.42
144.160.155.43

Rereading your original post - when you tried to connect the notebook - you used the same modem as your PC? And it didn't work?

When you changed out the modem (I assume this is DSL), did you check that your username and password were correct and that the VPI/VCI were set to 8 and 35 and Protocol was set to PPOE? Were you then able to do a ping to yahoo.com?

Will your browser (which one are you using), connect to the modem? (Do ipconfig and it should show the default gateway - usually 192.168.something.something. Type that into your browser.)

Are you able to connect to google with a browser if you type in 74.125.129.113?

[t3techcom18]

With both the desktop and the notebook, I was able to ping with both modems. Since its a commercial modem (CenturyLink), it does not have a login that is needed.

In terms of browsers: I'm testing both IE and Chrome (usually use Chrome).

A very interesting development today: I took the netbook to work today and the wifi there worked perfectly, albeit extremely slow. I updated the ethernet drivers and plugged it back in at home and, shockingly, its able to download Windows Updates. It's as if the internet has data in the background but not the foreground.

And I am not able to get onto Google via the IP you gave.

[RKinner]

It really sounds like we have a bad modem or Century link is blocking you with a bad config on their router. Since you have a laptop that works elsewhere we know it's not the laptop. Tho it would be good to know that it also connected via Ethernet and not just wirelessly. Have you got a neighbor with a router so you could plug in the laptop and verify that it can connect? Then you can call them again and tell them that it's definitely their equipment.


Have you tried to log in to it? Sometimes the status will tell you what is going on. We have Century Tel on Orcas and I often need to log in to their DSL modems to make changes. Never had any problem getting on their modems. The usual IP address is 192.168.2.1 (but check to see what IP Gateway IP address you get in ipconfig) and the default password for the 660 is 1234. Around here we have to log back in and set the username and password after a reset and sometimes the VPI/VCI (8 and 35) and Protocol (PPOE) tho that's usually only required when you use your router instead of theirs.

Which modem do you have in place now? The original or the spare?

Can you open a command prompt and do:

tracert  -d  8.8.8.8

Does that work?

[t3techcom18]

A tech friend of mine and I are starting to think its a hard line issue from CenturyLink too. The modem is the original (both modems are exactly the same make and model).

I tried logging into my own gateway IP, as you said, and instead of logging in, it immediately gave me that the webpage is not available.

As for the trace, it said, 'Destination host unreachable'.

[RKinner]

Does ping still work? Can you ping 8.8.8.8 ?

Does ipconfig

show a connection?

[t3techcom18]

How do I know ipconfig has a connection?

And I cannot ping; Sent 4, Recieved 3, Lost ;

Destination host unreachable.

Windows IP Configuration


Wireless LAN adapter Wireless Network Connection:

You might have better ping luck with just the Ethernet connected. Sometimes with two networks it will get confused. As it is if you get three out of four then there is some connectivity. The destination host unreachable looks like a network issue. Maybe a routing loop or it could just mean the connection to the router is coming and going.

if you type:

netstat -r

You should get something like this:

I did a restart and I can ping again; however, the physical address is still made of all 0's.

I restarted and I can ping again after it wasn't able to for a bit but the physical address still is made of all 0's.

[RKinner]

0.0.0.0 0.0.0.0 just means unless otherwise stated in the routing table use this line
0.0.0.0 0.0.0.0 192.168.2.1 192.168.2.10 276
which points at your default router 192.168.2.1 and tells it to get there via the interface which has IP 192.168.2.10 which is the IP address assigned to your PC via DHCP.


The odd thing about it is the metric is very high: 276 on mine it is only 25.


Persistent Routes: Network Address Netmask Gateway Address Metric 0.0.0.0 0.0.0.0 192.168.2.1


Another odd thing is a persistent route. We don't want it and that could make things run slow or not at all on another network.

Open a command window and type:

route  delete  0.0.0.0

then check netstat -r and see if the Persistent Route is gone.

If the route is gone try your ping again. Then try the tracert -d 8.8.8.8 and see if it still says destination host unreachable.

[t3techcom18]

The persistent route is now officially gone...HOWEVER....

Ping came back at a 100% loss.

As for tracer: Transmit error: code 1231.
