Evening all,

 I've bought the above switch roughly one week ago and used it for that period with multiple devices connected to it without issue. It's connected to a LAN port on the back of my Plusnet Hub One router, there are 3 devices attached to the switch (printer, work laptop and a desktop PC). I've noticed the speeds really start slowing on the laptop and started to notice it on the PC also however up until this point I'd noticed no change in speed, in fact I'd been testing it through the switch and connected directly to the router and the speeds were identical so was fully happy to endorse this TP link product... until now.

Yesterday I start getting "no internet" show up on both PC and laptop. Now can't get online, I've unplugged the TL-SG1005D switch and instead connected my PC via ethernet cable directly to my Plusnet router and receive instant internet access, try plugging back in with the switch and instantly get "no internet". The lights are flickering away on the back of the switch so it's not dead, it just doesn't seem to be allowing anything to pass through it. I've switched cables about to test if it's a wiring issue, a wasted effort given they clearly work as it was up and running with those cables for a week and none have been damaged in that time...

I don't get why this would work without issue for a week then all of a sudden stop?

I don't know which hardware verion it is, how do you tell?

I've seen there are a fair amount of people having similar issues when searching google and the resolutions don't provide a consistent answer to my situation, does anyone have any ideas I can try before I return this thing for a refund?

Thanks in advance.
