Problems with my wired network connection

[useless]

to sort it out you plugged in a different power adapter than the stock and ethernet still works when TV is off or HDMI unplugged? if yes, can you give as the adapter link or specs?

cheers

YES - I just used a 12V 2.5A adaptor I had at home similar to this (not the same model)

its probably the Intel driver issue. Will unistall and use the windows driver instead - that will fix it as am reading other forums as well.

In Windows (Davicom USB) network adapter is removable devices! There is a problem.


Just testing Lubuntu 14.04.2 (32-bit, kernel 3.16.0-31) that I have installed 16GB USB flashdisk. I have compiling drivers LAN + WiFi and introduced modules dm9620.ko + r8723bs.ko. The network works and having installed VLC, everythings O.K.

I may have a much simpler answer. I was having all sorts of issues with Ethernet. I simply invested in a new power adaptor and the problem went away. Just try one out first before doing anything else.

On Davicom chip I put the radiator and it did not help. Now (night) I turn USB\VID_0A46&PID_1269. I'll try again to simulate change VID and hopefully it will switch automatically and it will work.

My adapter (DM9261A USB To FastEther) is disconnected. I found that the changes USB\VID_0A46&PID_1269 to USB\VID_0000&PID_1269. I edited file DM9USB.inf from drivers and added USB\VID_0000&PID_1269 + reinstalled drivers. Maybe it will work....now to test....

I had to do that too !!! Well I didn't edit the INF but forced the installation of the driver.

I still don't know why it sometimes looses it's VID

I see you modified [DM9USB.NTx86] and [DM9USB.NTamd64] also. That's good. So you say that if we install your file the ethernet works when we take out the hdmi?

PS. I don't have the problem so I won't try it...

LAN can be disconected independently on HDMI.... LAN for me has nothing common with it HDMI.
You can test it.

It's happening to the original power supply. With the USB\VID_0000&PID_1269 it works all morning! I bought a external sound card (optical output) and LAN not want to buy.

It's inside the davicom chip. The reason you are seeing a bunch of zeros for the VID is the lost connection between the chip and the usb port. Suggestions:

1. Use the shipped power supply. Or at least measure with a multimeter that your power supply has a uniform voltage over time.

2. Buy an external USB to ethernet adapter.

Yes it happens when you play a movie. This morning was a USB\VID_0000&PID_1269, did not help restart.... maybe it dies ;-(
The VID&PID will be stored in the Davicom chip (about the eeprom) or in BIOS?
I have power supply of notebook 12V/5A.

Does it disconnect while playing a game/movie?? Ok my unit has never done this. Only some times after boot finishes it fails to detect the adapter. A reboot fixes that.

An edit to DM9USB.inf I think will not fix that. It needs more sections to edit in the file. Also the VID going to 0000 seems like the pipo looses the usb connection to the ethernet adapter (due to power?). Maybe another power supply might fix it...

When disconnected while playing a movie.... adapter switches to next driver.

another fine example of how the Chinese want to screw us. I wonder if they do this stuff on purpose?

[oversx]

You don't need to do that. Sometimes the adapter is disconnected after boot with no reason. All you have to do is reboot and it's there again.
