Help Please! Desktop can't find internet!

I would try the following:

1. Power down (not just restart) the computer and back on.

2. Go to you cable modem - turn it off for 30 seconds then back on

3. Do the same with your wireless router - off for 30 seconds and back on


I'll bet that fixes it.

I think you're right, but they need to be powered on in this order:

1. Cable Modem
2. Router
3. Computer

 

Doesn't really make much difference - I have to do it here every other month
or so and never much pay attention to order. One of the three boxes is "out of the loop"
is all it probably is - resetting all three should clear it up regardless of order,
at least in my own experience. Sometimes just doing just the router is all it takes.

The reason for that order is that the modem gets an ip from the network, the router from the modem, etc.

 

FIRST, let's make sure it is not the browser.

• hold the windows key and press "R"
• type "cmd" and hit enter
• type "ping ferrarichat.com"
• you should see some information come up like listed below

• type "exit"

If that worked, you have a browser issue, probably a connection, or it thinks it needs a proxy. Check the Tools>Internet Options>Connections>LAN Connections (button)

If that did not work, like there is no response and it says "100% loss" you may want to try the following, or just skip this part and go to tne next.

• hold the windows key and press "R"
• type "cmd" and hit enter
• type "ipconfig /release"
• type "ipconfig /renew"
• type "exit"
• reboot

Option 2

• open up your network connection
• go to wireless
• DELETE that wireless connection
• reboot
• click the wireless connection icon in the system tray
• select your network and re-enter the password
• open browser

Windows corrupts wifi a LOT, and it is usually a symptom of an O/S issue. This means clear a weekend to reinstall!

 

Time to try Testshoot's option 2 above - Delete it, and add it back again - No one really knows why, but hopefully that'll get it going again

Good luck, cheers,
Ian

 

Yep, sometimes Windows corrupts connections.

There ya go

 

The built-in wifi might have gone bad.

Get a USB or internal wifi card and try to connect with that. Or, try a wired connection if you can.

 

Next, instead of pinging to a domain name, ping to an IP.

ping 4.2.2.1

Let us know if you get replies.

If no, then the connection really is bad somewhere.
If yes, DNS is jacked up. Will provide a fix if this is it.

open the internet options in your browser. click network or lan settings, make sure this is blank.

 

In particular make sure that the box that says "use a proxy server for your lan" is unchecked. Tools - Internet Options - connections tab - lan settings.
Some recent malware changes the proxy settings so that you can only get to their site.
Next you'll want to look at your hosts file which in XP is located in C:\windows\system32\drivers\etc and is just called hosts with no extension.

Thanks for sharing that little tidbit!

Somewhat OT, but unworthy of a new thread (!) - Did anyone get screwed by McAfee's recent virus "dat" file update? - The one that decided that "svchost" was evil......

Bad, bad thing to happen as the box (basically) no longer knows which way is up, and furthermore the "easy" approach of mounting and patching from the network or even via a thumb drive doesn't work...... AFAIK, each and every machine that got hosed needed an "admin" visit

Cheers,

I know of a company (about 5K machines) that initially thought that a disgruntled employee had done it. They were in full panic mode for a while there but ended up coming out of it ok. I think that they are dropping McAfee because of it.
