Re: wifi ok but no ethernet ?
 

thanks for the link, I have never seen anything like that before and I will never use anything like that, it is cheap ass crap for people who don't have a clue about networking:

I completely understand why something like this would screw up a switch and cause it lock.

Re: wifi ok but no ethernet ?
 

Wouldn't it be simpler and safer just to use a cheap gigabit 5 port switch, for between £15 and £20?

In fact, there are some available for around £12.

(other switches are available...)

@ General Maximus, I don't use one of those cheap splitters . I am using a tps link 5 port splitter from pc world. I am just asking if a faulty ethernet cable (may be if wires were broken and shorted ) could cause the ports to freeze . I haven't had any problems today. Thanks

Re: wifi ok but no ethernet ?
 

If it is easy enough to swap the ethernet cable, then it’s probably best to try that first. It could be a faulty switch, which is what I’m gathering is being referred to when you say splitter, if so, then it’s cheap enough to get a Gigabit rated switch.

:banghead: are you sure it's not a TP Link 5 port switch? Can I have a link. A broken cable can definitely cause connectivity issues for the device it is connected to but I can't imagine it killing a switch. If it is a decent quality cable you would be hard pressed to break it tbh, there would an apparent cut in the cable somewhere in it's length or more likely at the termination at one of the ends where the wires go into the plastic bit (which may have come a bit loose). Either way, replacing the cable is relatively inexpensive and it should be easy enough for you to work out which one it is. If the switch is faulty or you need a new one of whatever it is you have got get one of these. Next time you need some new cable(s) or if you want to do everything properly now to save it happening again in the future then replace everything with the appropriate length of these. You can also colour code everything and for example, use a blue cable for your pc, grey for each of the 4 Amazon fire tv boxes and then a black cable for the connection from the switch to the shub. That way when you look at the cables (if you haven't labelled them) you know what each one does.

that is the switch . the cable that i think is faulty is a flat ethernet cable , and when plugged into the switch and the amazon box , the corresponding light on the switch , doesnt light , as if there is no activity , and the amazon box says there is no internet connection . i will test the port on the switch with a new cable . The only thing that was puzzling me is that i know the faulty cable was working in the morning , but hasnt worked since , thanks for all your help , im nearly there now .

Re: wifi ok but no ethernet ?
 

Flat cables are generally unreliable as they cannot be fully twisted.

Many consumer electronics devices only have 100mbps ports - e.g. my Sky Q boxes are all 100mbps, Hive, Hue, etc etc. It's more common than you'd expect.

You can in theory run two 100mbps connections over one cable with a splitter, as each only uses 2 pairs of the 4, with an adaptor at each end, but don't do it, it is bad.
