There have been various threads recently about posh Ethernet cables and mention has been made a few times that plugging them into an el cheapo consumer switch like my little Netgear might not be getting the best from them.
The idea of a pro switch was a bit scary as I'm something of a numpty and want plug and play. Then I discovered that pro switches could be used very simply if required.
SiS has mentioned the Cisco catalyst 2960 as being very good indeed, but at a price of course, like over £300. However you can pick up used ones for much less and my eBay purchase arrived today. It has a proper mains lead rather than wall wart, and amazingly after a minute or two it just worked. I was rather astonished by that, as computer stuff rarely runs smoothly in my house....
It's been warming up for a few hours and it will be interesting to see how it does and whether there is a difference. It's certainly built like a brick outhouse and the post leads go in with a reassuring thunk.
