Helping a church where 3 five year old Dell desktops that can get to the Internet via WIFI but not wired Ethernet. The wired connection shows active and has an IP address but cannot seem to get out to the internet. Both WIFI and wired pulling the client IP address from same subnet.

It worked several months ago. They blame some Windows update but cannot say specifically.

I have checked the port and cable with my Fluke meter and they show good.

Maybe a USB dongle is the easiest solution to try.

most of our company laptops require multiple ethernet ports in the field. USB/ethernet adapters reigh supreme for us. It's cheap and easy.
 
What ip addresses do they get on LAN - 192.xxx / 10.xxx or apipa (169.xxx)?

If not on Apipa- can they ping each other ?

What dhcp and dns servers does an ipconfig /all return in command line ? Are they the same ?

If you set them on manual ips, reenter all the ips as they were reported, but change the design server to google's or any other (try 8.8.8.8) - do they get to the internet?

Disable all unneeded protocols, and especially ipv6. Do a reset tcpip stack - what @rijndael said.
 
last month my wired verizon was down about 8 hrs, lots of cable work in my area lately!! reset things + lost all saved passwords etc!! came back on but with no stuff saved aka wrote down i had a LOT of work to do!!! STILL cant use Amazon my main shopping site. no wifi set up as i am not savy + DO NOT like WIRELESS + consider it UNHEALTHY!!

They get the same or similar address on wired or WIFI.

192.168.10.67
 
See if they can ping each other on wired.
Change the dns server address to 8.8.8.8 - there should be an option to either set a auto dhcp but manual dns, either all manual altogether.

But do the netsh command first. This can help. Google "netsh winsock reset".
 
It's probably a better to see if you ping your default gateway. There's no host firewall on the destination to worry about.
 
If you're ping'ing by IP and it works, but web browsing doesn't, it may be a DNS config / corruption issue.

If you're ping'ing by domain name, like "ping www.cisco.com", and it works ... then it's not a DNS issue.
 
Does Device Manager show the driver still work?


Also, do the dells still have the dell update manager installed on them? If so, download the NIC drivers from the dell website, uninstall the update manager, uninstall the NIC drivers, and install the new NIC drivers from Dell.

A lot of update managers from oems install a proprietary or slightly modified driver that will not work when the OS updates.

You can try ipconfig /release and reboot which is higher in the stack than netsh ip reset but I do not believe this will work.

A bad driver would disable the nic wouldn't it. His are grabbing ip leases and everything. @rijndael gave him plenty to try, my feeling is this will fix it.

Not in all cases. I don't know the details behind it but I've come across it a few times when using oem drivers. Netsh ipv4 /reset only resets the ipv4 back to default settings which could work if the ipv4 settings was changed.

Each IP address per interface should be different (edited my last post.) if they're the same, you may have an IP address conflict where the DHCP server/device is handing out duplicates.
 
Don't try to connect by wifi and wired at the same time. Disable the wifi system or forget the wifi network when trying to use wired.
 
So did some testing today. On wired I could ping 8.8.8.8 but not ping.ui.com.

Tried the netsh command followed by a reboot. Did not help.

Make your DNS setting one of these, rather than your default gateway. I've never liked using the gateway for that functionality.

I prefer OpenDNS for it's basic malware filtering.
