desperately hoping someone can help me!

I am on a small wireless network with a Linksys Router. I have windows xp pro.

Saturday night, all is well. Sunday morning, can't get online. Network works fine, other computer on same network works fine.

I run a virus scan and note multiple viruses which are Java related. Stupidly, I delete them without noting their names.

My wireless connection works fine, signal strength excellent. I hard wire the connection to the router, enter the primary and secondary DNS, etc. BUT, my browser can't connect. My outlook can't connect. I can't ping yahoo.

I disable all connections and then dial up to my ISP. Connect just fine. BUT, my browser and outlook still can't connect. I take someones suggestion to delete my wireless network connection and re-make it: I Can't! The "delete" is grayed out!

I have no idea what is wrong and I am not very experienced with these things. It appears that some of my settings have been corrupted and that I am unable to reach/identify connections to the internet. I have noted that when I rey to "repair" my wireless connection, it says can't renew the IP. When I go to the support part of the wireless network tab, it says "invalid IP address" and then has zeros for everything. What this means I do not know.

CAN ANYONE HELP ME?

Quick summary for : after deleting Java-related infections it’s common for the networking stack, proxy/hosts settings or services to get left in a bad state. ’s router power-cycle is a good first check, but the symptoms you describe (zero/invalid IPs, repair can’t renew, dial-up connects yet apps still fail) point to a local Windows networking problem (Winsock/TCP‑IP, proxy/hosts, disabled services or damaged drivers).

Do these quick diagnostics from an elevated Command Prompt and note the results:

ipconfig /all
ping 8.8.8.8
ping google.com
nslookup google.com

Interpretation notes: an address of 0.0.0.0 or 169.254.x.x means DHCP failed; ping by IP succeeding but name failing means DNS is bad; both pings failing usually means the TCP/IP stack, Winsock or a firewall is blocking traffic.

If diagnostics point to a local stack problem, attempt these repairs (run as administrator and reboot when prompted):

ipconfig /release
ipconfig /renew
ipconfig /flushdns
netsh winsock reset
netsh int ip reset resetlog.txt

Other checks before assuming hardware failure: confirm Internet Explorer/WinINet proxy is off (Tools → Internet Options → Connections → LAN Settings), open the hosts file at C:\Windows\System32\drivers\etc\hosts to look for malicious redirects, and ensure the DHCP Client and DNS Client services are Running/Automatic (services.msc). If the wireless profile “Remove” is greyed out, ensure you’re an administrator and that the vendor’s wireless utility isn’t managing profiles instead of Windows.

If problems persist: reinstall the NIC driver from Device Manager, try System Restore to a point before the deletions, and run an up‑to‑date anti‑malware scan from Safe Mode with Networking. Back up important data before major repairs.

When your computer can't get an IP address, either the computer can't properly communicate with the router or the router's configuration has the DHCP server (the part of routers that gives out IP addresses) turned off.

It doesn't sound like you've changed anything, so maybe your router just had a bit of a hicup. Turn off both of your machines, unplug the router, and turn off your broadband modem. Wait a couple of minutes. Turn the modem back on and let it fully initialize (takes about thirty seconds). Turn on the router and let it initialize (takes about thirty seconds again). Then turn on your machines and see if that cleared up the problem.

If that didn't fix your issue, we are going to have to figure out what went wrong with your configuration and what caused the change.
