This is probably not a great time for something in your home to break; so, of course since this is the worst possible time, ol' Murphy, has your back to teach you how good you had it.
For me it was my wireless router. About six days into being sent home from works, my very old Cisco wi-fi router went tits-up. Thankfully my cable modem has a few Ethernet ports, so I can run wires to my workstation to get all the "work from home" accomplished. Nevertheless, it still a pain in the ass. (I'm a little embarrassed to admit my router was from 2011, with its last updates to firmware in 2012.) Rather than buy a new one, I have my sister sending one of her used wifi routers.
Anyone else have a device they needed, break these past two weeks? Any delayed maintenance you wish you had not delayed?
