Z440 Windows 10 Ethernet unidentified network

HP Recommended
Z440
Microsoft Windows 10 (64-bit)

Purchased the Z440 used and everything has worked except the Ethernet connection. Just upgraded the drivers today (2018-04-18) with the same results: Unidentified network.  A TP-Link wireless adapter works fine. The driver file I installed is: "Intel Network Drivers - sp85254 - 2018-04-18" 

 

Running Diagnose yields: "Ethernet" doesn't have a valid IP configuration 

 

Running IPCONFIG 

 

Ethernet adapter Ethernet:

Connection-specific DNS Suffix . :
Link-local IPv6 Address . . . . . : fe80::199d:58de:d4:9f13%12
Autoconfiguration IPv4 Address. . : 169.254.159.19
Subnet Mask . . . . . . . . . . . : 255.255.0.0
Default Gateway . . . . . . . . . : fe80::201:5cff:fe88:4846%12 

 

Any suggestions? Thanks, Bill

Hello,

 

By the looks of it, you are familiar with command prompt.

I recommend trying the following commands:

 

ipconfig /release

 

press enter

 

ipconfig /renew

 

press enter

 

Seen many cases where this resolved the issue.

Please note there is a space between ipconfig and the '/' caracter, the font on this forum is weird.

 

Cheers

I apologize for not providing more info. I'd already tried your suggestion as well as several others that I found on the web. In fact, I'm not sure that it is a problem with my HP. So more details: 

 

  • neither my HP Z440 nor a iMac (since sold) would work on Ethernet, both work wirelessly
  • 2 different cable modems: Xfinity supplied and Netgear
  • 2 different wireless access points: Apple Airport Extreme and Linksys Velop 
  • with and without a Netgear switch
  • several different Ethernet cables, Cat 5 & 6; have tested these cables between the cable modem and wireless access point devices and they work fine 
  • connect either of the 2 above computers to the cable modems, wireless access points or Netgear switch
  • every combination imaginable: everything works wirelessly (including our smart phones, tablets and Chromebook) 
  • no setup works for Ethernet 

My HP configures the Ethernet network as: 

 

  • public network
  • Unidentified network 
  • "sees" the network, just doesn't allow access
  • my wife"s iMac can see but not connect to the HP Z440 

Very simple and mostly likely incorrect observation, the only common point is the service provided by Xfinity.  Roughly 6-9 months ago, Ethernet worked fine with both my old iMac and previous Z420. That was with the Xfinity cable modem and Apple Airport Extreme. What changed? Our Xfinity service was upgraded from 40 Mbs to 110 Mbs. 

 

While it is true that in theory they could block Ethernet traffic, the Ethernet connections to the Velop and Netgear switch work fine. It is only the "last mile" to the computers that fails.

Hi

 

The connection obtained by the WiFi is what?

 

Wireless LAN adapter WiFi:

Description . . : Realtek RTL8723BE

DHCP Enabled. . . . . . . . . . . : Yes

IPv4 Address. . . . . . . . : 192.168.0.11

Subnet Mask . . . . . . : 255.255.255.0

Default Gateway . .. . . . : 192.168.0.1

DHCP Server . . . . .. . . : 192.168.0.1

DNS Servers . . . . . . . . . . . :`8.8.8.8

8.8.4.4

Ethernet adapter Ethernet:

Description. .. : Realtek PCIe FE

DHCP Enabled. . . . . . . . . . . : Yes

IPv4 Address. .. . : 192.168.0.10

Subnet Mask . . . : 255.255.255.0

Default Gateway . . . : 192.168.0.1

DHCP Server . . . . . : 192.168.0.1

DNS Servers . . . . . . . . :`8.8.8.8

8.8.4.4

 

I can compare my connections.

 

If you can achieve something similar then maybe the problem area can be found and resolved.

 

So the long version of ipconfig -all please for WiFi and Ethernet.

CF4, 

 

Thanks for your info and sorry for being so slow to get back to you, it's gardening season so I've not been on my computer in awhile. 

 

I should have mentioned that I've been configuring ethernet on Windows systems since the days of coax hardware so I do, at least I think I do, know how to configure it. However for some reason, I can see but not change the settings. 

 

Anyway, I bought an AC wireless adapter which is running at over 100 Mbs so I'll just abandon any attempt to get ethernet working. So strange though. 10 years ago, configuring wireless was a nightmare while ethernet "just worked" and now it has reversed. 

 

Thanks again, 

Bill

Prego.

The fault is in the "Router" with dishing out DHCP addresses.
