Toshiba satellite p775d-s5172.

 

download on my home network from win7 worked, upgrade completed.

 

device manager does not list network card (neither wifi nor ethernet)

but has

other device>unknown device

  properties:the drivers were not installed. no compatible drivers

 

looking at network adapters:

  WIFI SAYS "On." and sees two available wifi, one of which is mine. "No internet, secured" has a 169 address. (again, not listed in device manager)

  Ethernet adaptersays "unidentified network. No internet"

 

ipconfig lists both connections with 169 addresses, no gateway or dns address

 

if, on the ethernet, I hard code the addresses, I can get out on the net... so it looks like dhcp is broken. hard coding the ip addresses is a temporary workaround.

 

but it's weird that the adapters are not in device manager

Right click the device, select Properties, and under the Details tab select Hardware IDs in the dropdown box. Copy and post the first line.

 

I did a search on your model number and nothing came up except this BC thread.

I think OP meant P755D-S5172.

 

+1 for hardware ID since that model has multiple hardware editions(Intel/Atheros/Realtek). See here for support site, Drivers and Updates > Wifi

Well, yes, I was dyslexic on the model #. My apologies.

I left the machine as described, but connected to the internet via ethernet to the router with manually coded IP addresses, including DNS and Gateway. When I got home after a long hot day, the unknown device is gone.

under control panel>Network & Internet>Network connections, I have

Local Area Connection. Network. Realtek PCIe FE Family Controller

Wireless Network Connection. Unidentified Network. Qualcomm Atheros ASR9002WB-1MG Wireless Network Adapter.
Bluetooth Network Connection. Not Connected. Bluetooth device (Personal Area Network)

Under device Manager

Network Adapters

>Bluetooth Device (Personal Area Network)

>Bluetooth Device (RFCOMM Protocol TDI)

>Qualcomm atheros AR9002WB-1NG Wireless network adapter

PCI\VEN_168C&DEV_002B&SUBSYS_7173144F&REV_01

>Realtek PCIe Family Controller

PCI\VEN_10EC&DEV_8136&REV_05

Did anything change as in your first post you said your network devices were not listed.

 

I would first try resetting your TCP/IP. Open a command prompt as administrator and type the following. Reboot.

netsh int ip reset c:\resetlog.txt

If there are no yellow exclamation points next to your wireless and Ethernet devices see if changing your DNS servers to OpenDNS works.

 

Flush the DNS cache after changing the servers as shown in the link.

well, I went and found two drivers each for realtek and atheros. I took the higher revision # and they both installed ok. I rebooted,

 

now I can't connect via ethernet at all. rebooted router, rebooted pc. no internet at all.

It appears I've made it worse.

I believe you can revert the drivers in Device Manager.

nothing changed except I hard coded IP addresses to get out on the router

I have run the netsh command (as admin)

 

rebooted

 

no yellow ! in device manager

 

the hard coded ip addresses were gone (except for dns), so I recoded them.

 

Yay. I have internet over ethernet.

 

Next, I remove the addresses (including dns) to use DHCP

 

Yay. I still have internet over ethernet.

 

It appears we have the lan drivers solved.

 

I tried connecting wifi, I unplugged ethernet. I still have internet via wifi.

it appears that it is all solved.


I believe you can revert the drivers in Device Manager.

apparently no need to.

by the way, this was a great experience. I'm used to very slow help on sites like this. Your quick replies today made this so much easier... I appreciate you greatly.
