Got a really strange issue with G105 - switch
I have a number of these switches around my house, and have an extension to a small summer house at the end of the garden. Was working fine, until animal ate throw the cable - so I have just fitted ...
I know that the tester says all 8 pairs are good but if the cable crimps on the end are slightly sketchy, it can work sometimes and not others. The switches can be a little more sensitive to that.
It makes it challenging to diagnosis.
try moving the one with issues into the house and connect it with a known good 6 ft cable.
If it stays stable, its the cable run or the ends.
I'd start with replacing the ends. To many times I've seen issues with crimps/ends of cables causing intermittent issues.
I was going to try replacing the ends, as I too thought that might be it, but was just shocked to see it work then fail an hour later. Was thinking of swapping my switches to the managed versions, but that's expensive just to be able to monitor and analyse.
You can try moving it, or just replacing the ends.
The benefit to moving it would be at least it'd tell you if the switch was the issue or not.
I have 4 cable ends to test, I have a box in the summer house, to a box in the garage, and then a cable from Garage to Back room where the switch is. The cable is the old original one I ran as the new armoured was too thick and heavy to twist and move, so I'll take a look at all the ends, but it's probably a poor crimp. I might even try to find my crone tool as I used one of the free plastic crap ones you get from old BT Sockets - so lots to test. Thanks for the motivation and confirmation it's probably my poor workmanship - I used to do a lot of cabling, but it was probably 30 years ago!! Still remember the colours which were drilled into by an old boss!!
