Question: I have a Freecom network drive 500 GB which I use for backups over the network. However, it seems to go offline and has to be turned off and turned back on. Any ideas how to fix this?

The drive is: [Freecom-Network-Hard-Drive-FND-Network-Attached-Storage-NAS-500-GB](http://www.ebay.co.uk/itm/Freecom-Network-Hard-Drive-FND-Network-Attached-Storage-NAS-500-GB-/151018854979?pt=UK_Computing_Home_Network_Storage_NAS_2&hash=item23296cda43&ssPageName=RSS:B:SHOP:GB:101)  

(sorry only link i could find)

It's got the most up-to-date firmware as well.

Answer: 
It's probably the best to remove the default route to disable internet access:

```
route delete 0.0.0.0 mask 0.0.0.0

```

And to re-enable, add it back again:

```
route add 0.0.0.0 mask 0.0.0.0 192.168.1.1

```

but replace the `192.168.1.1` with the correct IP of your router (you can find out while the internet is still working by typing `route print` and checking the entry for `0.0.0.0`).
You should log into the router and tell it to disconnect from the internet. Unless you only want to deny specific computers access?
