I have a severely annoying issue I'm hoping you guys can help with. Here is my setup:

Virgin Suberhub 2.0
Port 1 - To Sony Laptop just adjacent
Port 2 - Western Digital 3TB NAS
Port 3 - Western Digital 3TB NAS
Port 4 - CAT5e cable going downstairs to my front room, in to Netgear GS105 switch and two cables out, 1 to Acer Revo XBMC HTPC and 1 to PS4

For months this setup worked faultless. One day neither the PS4 or Acer could obtain an IP. For a few days this was intermittent but was remedied by resetting the router and switch (at that time a TP Link model). Then eventually it didn't work at all, but did sometimes work when swapping connections about on the switch. Further on, it all failed completely. After removing the switch and plugging in direct it worked fine, so confirmed my thoughts it was the switch. May be a completely unrelated issue but sometimes the connection was present but clearly shaky, as was experiencing buffering on XBMC when streaming from my NAS.

It was replaced with a Netgear GS105 - worked great and all was well. However a few month on, exactly the same issues now. I have took advantage of the Netgear lifetime warranty and sent the switch back - a replacement was received yesterday.

Plugged it in, worked great. Literally 3 hours or so later - the lot went off again.

In between waiting for the replacement, I've had the PS4 connecting wirelessly (shudder) and the Acer Revo connecting direct to port 4 of the Superhub. It's worked faultlessly. I also need to emphasise despite losing connections downstairs, the laptop and other connections were working fine so I've ruled out the Superhub. To preempt the suggestion, I've also swapped ports around on the Superhub too thinking it may have been an issue on port 4.

I'd prefer a direct connection on the PS4 rather than wireless as I'm sure it must be worse latency? My only option right now is consider trailing another cat5e cable downstairs alongside the existing or forking more money out for a third switch to try.

Am I simply unlucky with switches or what?

Have you tested the wall plug that the switch is going into? Could be faulty and causing it to short out and damage the internals of the switches. Long shot, but can be a problem.

I did start to consider it may be power supply rated but dont have access to an alternative power pack. I did try swapping power outlets to no benefit.
 
Would one of these work if I'm only using one device at a time? The other being in sleep mode? http://www.amazon.co.uk/RJ45-Ethernet-Splitter-Connector-Adapter/dp/B004SJXRP4/ref=sr_1_1?ie=UTF8&qid=1394874668&sr=8-1&keywords=2+cat5+splitter

How are you going to connect it at the router end? You're going to need two spare ports, and you only appear to have one available.

Perhaps Ive misunderstood then. I envisaged router port 4 to adaptor, the 2x cat5 from the adaptor, one to acer revo and one to ps4?
 
They're completely passive devices. They just allow two connections over a single cable. They exploit the fact that a 10/100 connection only requires two pairs, and network cables contain four pairs. Gigabit uses all four pairs for a single connection.

If you want to plug five devices into a router with four ports you'll need a network switch somewhere.
 
Without a switch you haven't got enough ports. Your original setup with the switch downstairs was the correct solution. I think you've just been very unlucky and should try it again.

The only other sensible option is to have the switch plugged in upstairs and then run two network cables downstairs (or the single cable with those economisers plugged in).
