Although there is a thread already about the packet loss issue, mine appears to be slightly different.
I only seem to have any issue when connected via ethernet, wireless has NO issues whatsover.
Would this be a bad router/switch etc?
No matter which cable and/or router port is used (and whichever PC/Laptop etc is used), I get packet loss.
WiFi is not ideal in our house due to a weak signal upstairs.
We do a lot of streaming and my Son does a lot of gaming (Xbox Live).
Just to add that nothing had changed (hardware/software/settings) since before all this happened (early Sunday morning) and since then, lucky to get 10 minutes stable on wired connection but wireless is fine.
