Extremely slow network on RPi

Glad you’ve got it sorted. I’m interested to know the cause though – tell us about the cable. How long is it, is there any visible damage, does it have anything printed on the outside? It’s very odd for this to cause a delay without showing errors (though I suppose they could all be transmit errors not receive ones)

The cable is old (about 10 years), several meters long, and it has a lot of knots of his own (apart from the giant knot of wires to which it belongs, I mean). There are no further visible damages, but it has always served an old Window98 computer that got extremely slow in the end… maybe because of a malfunctioning cable?

On the outside is printed: cat.5 UTP 24AWG 4pa… and the rest vanishes under the plug.

I’m still puzzled how I could change cables and yet connect the faulty one again – several times!

New cables don’t always work either. I have a recent 1.8 metre usb 2 extension cable and it doesn’t like memory sticks or card readers. Mind you, different usb sockets on my Iyonix have different ‘personalities’

Who was that man that said check the cable again???

Dunno, but If it’s possible it will be done.
Now consider this:
An office with feeds from 2 networks
i. NHS devices
ii. PFI contractor network. Several emplyees of the PFI contractor need to access both and have PC on each.
iii. There are too few ports to allow connection for all to have two PC’s, enter the mini-hub.

So, how do you disconnect all devices to allow a new carpet to be fitted and then reconnect all devices, including connecting the mini-hub to both networks…¹
I hate mini-hubs.
But since one cable set is grey and the other is red what does it take to get both connected like that? (apart from a grey cell deficiency)
Now with the same colour cables, what’s the chance of a mistake? As I said: If it’s possible it will be done.

¹ RADIUS didn’t allow the non-authorised devices access. STP blocked the port preventing a network bridge.
