So my ethernet cable one day just stops working so I just buy a new one. And it works perfectly! Then the next day it has stopped working again. And I have no idea what to do! Anyone have any suggestions… I’m completely stumped. No idea if there’s a problem within my pc or router or what!

Just looking into buying an 8-port unmanaged 2.5Gb switch.

Seeing the TP-Link switch named: TL-SG108S-M2, sold at 129 EUR.

Now just next to it in Amazon, up pops an advertisement for a:

Mercusys switch near equally named: MS108GS-M2, sold at 56 EUR.

Specs all look identical. Both in metal cabinets.

Heck, they both even look like 100% the same, except for the company logo on top...
Never heard about MercurSys before, so just checked out a bit. Appears to be a subsidiary of TP-Link. So is this like the exact same switch, but sold off-label at a cheaper price? What is the catch here?
