Turn the router off for a few mins. Then back on. See what that does.

Zep, it tries to authenticate connection, then it reads limited or no connectivity. I checked all the lights on the front of the router, they are working fine.
I turned off router, modem, computers, xbox in order given by netgear website.Nothing.

When I try to repair the connection, it says renewing IP address, then it cannot complete repair because the ARP cache needs to be cleared.?

Tried that too. But not sure if I have more than one firewall. I only disabled the one in Windows Security Center. I should mention,sometimes the internet connection says it's Connected and Firewalled, but it won't log onto internet and the icon in bottom corner has red yellow shield with exclamation point.

you should only have one software firewall on the pc at a time that can cause serious problems if you have more than one. The router itself will have a hardware firewall built in that is different.
You need to determine what firewalls you have. What antivirus program are you using? is it a suite that would also have a firewall included?
did you try starting in safe mode with networking to see if you could connect to a site like google?

I have AVG Free Edition for antivirus. I do only have one firewall. Thanks ofr explaining about the router firewall. I stared comp. in safe mode w/ networking, couldn't connect. Anything elae I should do while in safe mode?

No, it's funny just moving the computer caused this. The only thing I could suggest is to double check the connections on the back of the computer again. Usually no connection or cable problem would show a red x down by the clock over the computer Icon.

The only other idea is a system restore and or checking device manger for errors. Seems overkill though for a computer that was just moved.

Just to clear something up for myself, are you trying to connect the desktop wireless, or a cable from router to desktop?

Prior to moving the computer was it shut down in the correct manner, as opposed to just un plugging it. This happens sometimes. If that did happen the a System Restore for sure.

It was shut down correctly.

Using a cable from router to desktop. I just moved the router. Computer is in same place.

Must be some issue with the router. I forgot that you said it connects to internet when connected directly to modem.

I'm at a loss here. And I know it's something silly!!!

Thank you!I did a system restore. It did enable me to have connectivity,but the internet page never finishes loading...?? My computer is an old one,have to wait to get a new one. Using firefox.

I can give you some cleaning tools after a bit, or others will. I think you should run a Malwarebytes free version scan, and Ccleaner. Though Ccleaner includes a registry cleaner, we don't suggest using it as they have been reported to clean out registry entries that are needed and messing up some PC's. And what they do clean up is so small that little or no advantages are noticed.

zep

I would definitely at least run a malwarebytes scan, and an online virus scan.
Downloading and installing Malwarebytes' Anti-Malware on a Windows computer * Anti-Malware * download * install

ESET Online Scanner

try a full power down of everything, computers, router, modem, etc. leave turned off for 5 mins or so, then power up in this order, power to modem and let it get fully up and running all lights on, then power to router also let fully light up, then power to your pc that is having the problem(you should have it connected to router as it would normally be), let it fully get booted then try it and see if that helped, if so then you can go ahead and try adding the other items to power up one at a time.

Thanks for the help. I ran the Malwarebytes free version scan, and Ccleaner without the registry cleaner, no infections. Luckily, these downloads were already on the computer. Raven, if I need to download programs from the internet, could I use my laptop with internet access to copy program onto a DVD and install it on the other computer that way?

I did a full power down of everything, then reboot in order. Nothing, still can't load internet pages. There is no computer icon on desktop showing a connection and when I go into Network Connections, it's blank.

ok have you tried different cables? cables do go bad so try a different cable from the pc to the router and try it in different ports in the back of the router.

I tried that too! I did have a connection, just wasn't loading pages. Now I don't have any connection icon or any status when I go into Network Connections....? Tried to do another system restore but, it won't go back far enough, only to Sept. 1st.

you can go back further on your system restore if you look at the little calendar there is a forward and back arrow beside the current month you have to click that back pointing arrow to go to the previous month to see those restore dates.

It sounds like maybe your card has died in the pc, that happens, I have had to replace them before.
NIC Card Troubleshooting

this is a youtube where they go over various options for this kind of problem, might not hurt to listen to it.
How to Fix Network Card Issues

there are also lots of youtube videos on replacing the nic card.

But in the original post the user confirms that the pc connects when connected directly to the modem?????? Is this still true?

yep you are right, in that last post sounded like everything is no longer working??? guess we need a bit more info and clarification on when and how it does actually connect and work??

I am confused can you tell LOL

Oh my gosh, sorry guys! I'm really confused too!LOL I originally did have connectivity directly thru modem w/o the router and it did load the internet pages, but with the router(the computers icon had yellow shield w/ ! in it) wouldn't connect to internet.
It seems like after I did the system restore the first time, it did enable me to have connectivity,with the router and modem but the internet page never finishes loading...??
After I ran the Malwarebytes free version scan, and Ccleaner without the registry cleaner, no infections by the way, Now I don't have any connection icon or any status when I go into Network Connections....? When I try to click on Mozilla, it looks like it's going to load, but never does.
I tried the power down in order given too.
I also tried to do another system restore but, it won't go back far enough, only to Sept. 1st. Can't get it to go back to August.
???? Thank you for bearing with me.:)
