Solved Diamond TV wonder PCI-E disables my network adapter on Acer

March 9, 2013 at 11:48:22
Specs: Windows 7, AMD E-450/ 4 GB
I am having issues with my Acer computer. It is a Acer Aspire # X1430G I bought it new almost a year ago. I wanted to add a TV tuner. It is a ATI TV Wonder HD 750 It is goes in my PCI-Express slot. After I install it every time it disables my network and cannot use the internet. My network adapter is on-board and not a card. It says the name is a Realtek PCIe GBE Family Controller. I have tried messing with settings. I start up in safe mode with network access and internet works there. I am wondering if anyone else is having this problem and found a fix. or knows of something I can try to get it to work I know a long time ago you would have to do something with a IRQ if things were not working together. I am not sure that applies in this case. Thank you for any help you can give me.

Just letting everyone know that I decided to get the USB version of the same card I was using and it is working perfectly. So for some reason my computer did not like the PCI-e version of this TV tuner. Glad to finally have a TV tuner that works after almost a year. Thanks for all your help.

All modern versions of Windows can manage IRQ sharing where required. There is no longer any need to change resource settings manually.

All I can suggest is you install a PCI network card and disable on-board LAN in BIOS Setup.

I wanted to mention the TV wonder TV tuner fits in a PCI exrpess 1X slot. I only have a PCIe 16x slot available. With the TV tuner in the computer. in Device Manager under Network Adapters. It says it is working properly. But LAN is not working. And when you push the button to try to scan to diagnose the problem the computer will freeze every time. And I have to turn off the computer and reboot. I have no idea why installing a card in a expansion slot will make your LAN go haywire and you take out the TV tuner and LAN is working great. I do not know what could be conflicting.

My guess is it has something to do with using the x16 slot rather than the x1 slot. According to Acer, your motherboard does have an x1 slot, what's in it?

I think you must have read what I wrote wrong. The TV tuner card is in the 1x slot. nothing in the 16x right now. I might try to find a network card that will fit it. Not sure about all these new kinds of expansion slots. I know a lot about computers. but I used my last one for 9 years before I got my new one. My computer now is a low profile one so trying to make sure all cards will fit or have an adapter. Anyway. there is something with these brand of TV tuners. I read online another guy had the same problem I am having. He just went and got another brand of Tuner. I cant afford something else right now so really would like to get the one I have to work if at all possible.

OK, did you try it in the x16 slot then? x16 is backwards compatible with x8, x4, & x1 so an x1 card should work. If there's some sort of conflict with the x1 slot, maybe not with the x16? Check the following link, 4th paragraph down (I can't get it to copy):

Also, did you run thru the BIOS settings to see if there's anything for IRQ? Make sure it's set to Auto.

That would blow my mind if a 1x card would fit in a 16x slot. Well I actually tried it and my computer would not even start up. it just beeped. So still makes me think it is not possible for that to work. I do not think it is a IRQ problem. Like I said it is saying there is no conflicts. It is just changing something in my network. That is what is so weird about this as why installing a expansion card would change something in my LAN. This is very frustrating. Thank you for the idea and giving me something to try though.
