Wired Network Issue

I've been searching around for a fix to my issues but I cant seem to find one so Ill try just taking a stab in the dark and seeing if anyone will reply.

Now..

I am using my on-board RTL8168C NIC to connect to a Netgear DG834Gv2 using a cat5 cable. My network connection state varies from full access to none at all. Sometimes I turn the computer on and it works fine, other times I have to disable then enable the NIC 5-10 times and eventually it works.....then doesn't work.

It also appears that when all the planets align,and for some reason or another I can actually get on the network...that the NIC gets "overloaded" with information then just disconnects me. Say for example, I can go around facebook and google, that sort of thing fine (when said connection is working) but say if I want to load up something like World of Warcraft it appears to break my connection.

I have tried using Gigabytes drivers on their webpage specific to my mobo, I have gone to Realteks website and used their latest drivers and I have also just used the bog standard windows 7 drivers, it appears when I do uninstall the device and then reinstall it with one of the drivers the device appears to work but then after 5-10 minutes maybe, the device fails me again.

I've been reading around and I have disabled the Bonjour service and set up the network as "Work" network.

This issue seems to come and go too. It appears to hang around from a day or 2, somehow repair itself and be fine for another 2-3 weeks and break again. Actually since Sunday I have been having this problem, Saturday I was pretty much downloading all day at my max 150kbps (Go go Australia's amazingly fast internet ) no problems at all.

We have 2 other computers on the network, 2 laptops, One using 7, the other using Vista, They do not have any issues at all.

Anyway, here are 2 IPConfig's One where my network connection is fine, The other where it is broken.
