Finally got round to asking about this after months of annoyance Since getting windows 7, my internet connection occasionally drops for a little while. Does not happen on other XP computers on the network. I usually go 'Disable' then 'Enable' which seems to fix it sometimes I have tried numerous things which I have read, like in Realtek options changing 'Network Address' from 'Not Present' to a random value like '123456789ABC'. I don't really know what these things do and I don't think they are actually affecting anything. Interestingly, the internet would NEVER stop working when i was playing an online game. Someone then suggested unticking 'Allow the computer to turn off this device to save power' in Realtek options. I thouht this may have worked for a while, but then the issue seemed to start again, and this time internet would also stop working in online games. So confused.
