OK...I know there are hundreds of threads on this topic, but I cannot find any help in ones listed. Or maybe...I am just over looking a small step. So here is my issue....

I have a linksys G router for our two laptops for remote and the desktop wired into the router. It worked in this configuration before Christmas. Desktop states that it has "Limited or No Connectivity". So I unhook from the router and plug straight into modem...same thing.

Here is my info:

Windows IP Configuration

Host Name . . . . . . . . . . . . : home
Primary DNS Suffix . . . . . . . :
Node Type . . . . . . . . . . . . : Hybrid
IP Routing Enabled. . . . . . . . : No

Ethernet adapter Local Area Connection 4:

Subnet Mask . . . . . . . . . . . : 255.255.0.0
Default Gateway . . . . . . . . . :

Here is what I have done so far:
1. Un-installed and re-installed drivers
2. Manually and automatic IP address in the properties
3. ipconfig/renew
4. Change from router to wall connection and back
5. Ran network wizard

The only thing that I haven't done is pull up the router's webpage and directly enter the computer itself as one of the computers to accept, but I never had to do this prior.

Can anyone suggest what my next step should be? Any assistance would be extremely helpful. Thanks in advance.Hello Lost_Hope, welcome to CH.

What operating system is this?I've had the exact same problem with my desktop computer. Up till today, it's still a bit shaky. Sometimes it's limited or no connectivity, and sometimes it behaves normally. My guess is the machine's too old, i've had it for 8 - 9 years already.

How long have you had your machine for?The machine is almost 3 years old. I am running XP and IE7, but I think that I am going to change over to Foxfire. The machine has worked great until almost a week ago. I thought the modem went bad, upgraded the modem and still same same. I dont know what the root of this evil is?It's called Firefox.

Have you recently scanned for virus/malware in Safe Mode?No I haven't. I dont know why I didnt think of that. Thanks for the reminder.

BTW..."Foxfire" is an old publication(s) of how things where in the frontier DAYS and not a web browser. I need to stop looking at the books in the house when I type...lol. But that is what happens when the wife and I collect antiques. Thanks again.Set your DHCP server and default gateway to the routers IP address.Did the virus SCAN and set the addresses to the router...and still no connection. Anybody have any other suggestions before I have to take it in to be serviced? Thanks in advance.Now that you have those settings, try rebooting the router. Remove the power for about 30 seconds or so then reapply power.You could do a total reset of the router...but i doubt that would work.

It could be that your ethernet cable is damaged. Try getting a new one?1. Is it just the "desktop" computer that has connectivity problems? Do the laptops still have internet connectivity through the router and modem?

2. The IP address "169.254.70.51" indicates the desktop upon boot was unable to locate a DHCP server for assignment of IP Address, Subnet Mask, and probably DNS server addresses. In a Home Local Area Network (LAN), the DHCP server function is usually enabled and provided by the router (e.g. Linksys G Router).

The address "169.254.70.51" indicates a basic network connectivity problem, not an internet connectivity problem. The problem is on the LAN side of the router, not the WAN (internet) side. (I've been told "ipconfig /renew" won't refresh this. You must correct cause and reboot desktop to reset IP address)
Either there is no DHCP server available or there is a physical connectivity problem within your LAN.

Possible causes:

o Overall bad router (try different router or eliminate router altogether)
o DHCP function not enabled within router (enable within configuration)
o Bad LAN port on router (try different LAN port)
o Bad ethernet cable (try different cable)
o Bad LAN port on desktop

3. Suggest the following:
o Check the status LEDs for desktop and router for the ports the ethernet cable connects to. Desktop usually has at least two LEDs; link and activity status.
o Use "ping" utility at desktop to test TCP/IP software stack and NIC card access.
- Test software stack "ping 127.0.0.1"
- Test NIC card access "ping 169.254.70.51" or whatever current IP address value.
o Setup two computer LAN by using CROSSOVER ethernet cable to directly connect desktop LAN port to one of the laptop LAN ports. Manually configure static IP configuration on both to place on same LAN. Drop firewalls to allow ping through. See if they can ping each other.
