charter/spectrum internet and modem, tp link4000 router. for over a year i used a Ethernet switch , it was a d link des 1024d, it suddenly stopped sending data to ever port, so i assumed it was dead, i bought a d link dss16+, everything worked good for about two months, then it did the same thing, the lights flash as if it is sending data out same as the des 1024d did, so i had two small cheaper ethernet switchs a small brash 5 port and a a netgear gs605 5 port, if i hook these two up the ethernet works, i have got three more switches, they will not send data out on all ports, only the two junk small switches will. do i have a router problem ? all these are non manged switches. any help would be greatly appreciated.
