Hello peeps:)
Have a really strange networking problem:o

Was connected this morning fine, shut down and went to work. When I got back I disconnected all the cables and opened case and inserted a new 2gb ram stick I purchased today to go with the other 2gb stick. Reconnected all cables and booted up perfectly, PC running great until I tried to go on to network/internet. Says no network cable plugged in :confused:

Pugged it back in and tried another cable same thing. The lights on the router for the ethernet port I am using flash on and off every 3 seconds or so. My laptop connected perfectly to the router using the exact same cable.

Strange thing is if I connect my laptop to the router wirelessly, and connect the laptop to the desktop via cable with a bridged connection it connects fine?

What gives?

My specs in sig and router is a Netgear DG834GT
 
It sounds like somehow you stuffed up your network card.

Can you connect your pc to your laptop with the cable?
 
yes.

and if I set up a bridge on the laptop I can connect to the internet no problem on the desktop.
 
Sounds strange that u can bridge your lappy and the pc, but cant connect it to the router.
If the pc works connected to the laptop, then the network card should be fine.
Maybe reset the router? Just as a test?
If not uninstall network card and re-install.
 
I have rebooted router.
I have unplugged everything that is not neccessary (dvdrw, other hdd, other ram, hd4850 etc)
I have uninstalled drivers and re-installed
I have disabled and re-enabled it in bios

When I plug desktop to router no lights on the motherboard ethernet jack are on but the router flashes on off every 3 seconds.

When I plug desktop to laptop lights on the motherboard ethernet jack turn on straight away.
 
Try setting the line speed of your network adapter manually. set it to 100mbit duplex. There might be an compatibility issue with your lan card and your router
 
Will try survo, just busy installing XP on another computer atm.
 
Router probably had a power surge or something. We've got the exact same problem here. Router won't connect with ISP details, but if we use a bridged connection it works fine.

Dude you are my here, kinda.

It only works properly with 10mbit full duplex...
 
mmm, sounds like a faulty something somewhere. Normally I would exclude the PC hardware first by booting the PC with a Ubuntu Live CD.

If it works fine, reinstall windows, the problem is software
If it has similar problems, take your hardware in to be tested, you might have a faulty NIC.

Doesn't want to work on ubuntu either, just flashing light on the port of the router. Going to take it in on Monday I hope they don't have an issue with the overclock.

Assuming you have a 4-port router, reset your PC to speed to autosense, then try plugging the network cable into each router port and see if any work.

Have done so. Tried all ports and they work fine with other computers not mine.
 
I have been googling the problem all night and while I don't have an exact match to what I have had I came accross this thread.

One of the people who posted in the thread commented that with boards like the g31 with overclocks often comes other issues like dodgy gpu performace, flakey vga etc. I have noticed some rather funky looking screens in the bios during bootup before the HD4850 takes over.

Removed the OC yesterday and network was still dodgy but tonight it seems to be fine again. Strange..
