Ethernet not connected

[Penfold7]

I recently swapped and relocated my router. I also bought new Cat6 cables for my 3 Ethernet connected devices, a sky q box, Sony android TV, and a powerline adapter.
Since then I’ve had issues with the TV every couple of days dropping the Ethernet connection, and it being a pain to restore. Sometimes unplugging and plugging in the cable works, reboot TV or reboot router. All other Ethernet devices are fine. I was suspecting the TV had a DHCP lease issue, but I appear to have solved the issue by replacing the Ethernet cable to TV with a cat5e cable and it’s been fine. My question is, why would a cat5 cable be fine but a Cat6 not… The other 2 devices are fine on these cables. I was under the impression cat6 was backward compatible. I would be interested in people’s opinions, unless it was just a faulty cable ???

You bought the same cables for all 3 devices? Try switching them around to see if one of the Cat6 is faulty.

If you were having no issues with the other devices, I would imagine it to be a cable issue.

@Penfold7 - any news?

Sounds good, @veeg can mark this as pending and you can get back to us in a few days.

[Bruce]

did you get shielded or unshielded cat6 cable?
what is the cable run length from the TV to the modem/router?

what are the differences between the cat5 and 6 that you know, like cat5e and cat6a, solid vs stranded?

Hi Bruce. Whilst I am a little knowledgeable about networking, your questions are a little beyond me???. The cables I got were 3m in length. All 3 I bought were the same type. Cable run from router to TV, Sky box and powerline adapter are all about the same. These are the cables I bought from Amazon.

i was trying to see if there were any differences between the cable the worked and the one that didn’t.
has the TV lost connection since changing the ethernet cable?

[Penfold7]

I’ve been checking every day. It’s renewed it’s lease today according to the router. I’ll check If the TV still has a connection later on. Only reason I never suspected the cable was they were all new and the other 2 were working fine, and on a couple of occasions when I swapped ports on the router connection came back up. Lesson for me, always check the simplest things first???

[Penfold7]

The TV is still connected, so barring anything else looks like a cable issue. To be honest the symptoms were a bit odd for a cable issue, I would have assumed the cable would either work or not. I wasn’t expecting bizarre connection issues like this, were a router or TV reboot, or even just changing port on router sometimes would make the connection again ..
You live and learn ???

[Bruce]

yeah, computers and tech can be like that.
let’s leave this open a couple more days and see if anything happens.

closing as solved (y)

Typically as soon as thread closed the issue reoccurs…
Can’t really be another cable issue, but it’s odd this one stayed connected for longer. A cat5 cable stayed connected. I’m at a loss now. Options I feel are.
1.. switch to a cat5 cable
2.. swap out the router for another one. I’m currently using a BT business hub 6, but I do have my older Plusnet hubq
3.. it’s the TV at fault. I have contacted Sony, but they are not very helpful…asking me to do odd things like connect the TV to my mobile via a hotspot.
4.. give up and use wireless for the TV and see if that works…

Happy if anyone has any other ideas

I’ve got ethernet back by swapping ports on the router. I’m feeling more and more this is a router issue
