How many network adapters dos a PC need.

I know nothing at all about network adapters apart from what I have learned in the past hour's research.

I have built a PC: Asus A8R32-MVP deluxe motherboard and radeon 1900xtx graphics card etc. It's a high spec rig but I have had IRQ and other conflicts which have been largely solved by uninstalling the audigy 2 nx sound card (temporarily).

Looking in device manager I have 4 network adapters:
1) 1394 net adapter;
2) Marvell Yukon 88E8001/8003/8010PCI gigabit ethernet controller
3)Marvell Yukon 88E8053 pcie gigabit ethernet controller
4) Speed touch USB ADSL ppp

I have one pc and do not intend to do any home networking -it's just the one PC. I know 4) is my internet connection.


Number 3 is sharing an IRQ with my graphics card which may explain some of the IRQ errors.

My questions are:

1) Do i need the first three adapters;
2) If not can I safely disable them.

I want to disable them to reduce the chance of future IRQ conflicts.

Looking at the events viewer, some of the conflicts have mentioned a 'server' which I assume is something to do with networking and a device trying to communicate with a server which does not exist, and that device trying to communicate, I have assumed is one of the adapters.

"DCOM got error the service database is locked attempting to start tehh server SENS with arguments in order to run the server...."

Sorry if this is garbled...

 

Controllers 2 and 3 are your onboard gigabit ethernet ports on your motherboard. I'm not totally sure on how to disable these properly. You may want to look in your BIOS of any options to disable the ethernet controllers. failing that try going into device manager and click the 2 ethernet devices and uninstall them via a button at the top.

The IEEE1394 adapter is actually your firewire port that can be used to connect video cameras/firewire devices. If you're not going to use this, then you can disable that as well.

 

Thanks.

I'll disable the 1394 then until I need to use it, if ever.

But I don't know if I need adapters 2 and 3. I'm thinking of disabling them as a possible solution to the conflicts and error messages I've been getting. Problem is, I don't know if I'm using them. Lol.

I suspect not because this is a standalone PC with one connection to the internet namely adapter 4.

Knowing my luck i'll start WWIII by disabling them.

 

If you're connecting to the internet via a USB modem then you don't need the ethernet ports as it is a stand alone PC.

 

In which case I can disable 1,2 and 3 with confidence.

Thanks for your time and expertise.
