Auto split network bandwidth

Does this apply to all switches?
No, rate limiting / traffic shaping is a thing but only on routers, higher end switches, access points etc, its not a feature on cheap domestic £20 L2 switches like you are using.

Example a hospital might have guest WiFi access but they wouldn't want all the bandwidth taken if everyone started watching Netflix on their phone so they could rate limit the guest WiFi to a set % of their total bandwidth.

In your case either something is broken, the other devices are doing something in the background which is generating traffic or you are misinterpreting the results some how.



I've tried another port on my sky router to share the Internet to the switch. It doesn't make any difference.
I think they meant unplug the switch and only use the ports on the router to see what happens without the switch.

EG PC in port 1 of router = 500Mbps
Then add a TV to port 2 = still 500Mbps on PC?
Add another TV to port 3 = still 500Mbps or drops?


500mb is reported in either device when checked using ookla speed test
but if you add another tv to the switch it drops or has it starting working correctly now?



TV firmware upto date, no sideloaded IP TV APPS, you aren't in a botnet?
 
I might have found the issue. Maybe someone knows of this or can explain why.
Unplugged all cables from switch. Then plugged in laptop and speed of 500mb achieved.
Then the following rooms all with ethernet sockets in the walls were plugged in one at a time.
The four rooms that had ethernet cables from wall sockets all went into a sky box. Main room Sky Q, then 3 other rooms with sky mini boxes. If I plugged any one of those cables into the switch from connected to a sky device ( Not the actual TV ) then the speed on my laptop speed test dropped significantly. Even with just one sky box plugged in. Plugging in all of them resulted in a net speed from the laptop of no greater than 90mb. The PC is directly plugged into the switch via cable.
However if I plugged in all cables that lead to the wall sockets but don't connected the sockets to the sky boxes I do still get the 500mb.
So it seems the sky devices that are in standby and not on to view content ( no streaming or viewing etc ) they have a severe speed impact on any other device connected via ethernet.
If I connect the sky boxes via wifi ( not the preferred option ), this doesn't impact the speed at the laptop.

How can a connected sky box in standby mode, reduce the speed output at a wall socket for any other device. I understand if they are on and streaming content and taking up bandwidth. But in this instance they are not.
I have also connected one of the wall outlets to a TV using an ethernet cable and it doesn't impact bandwidth like the sky boxes do.

For confirmation the ethernet socket that connects to a wall outlet for the office and has a device connected to it doesn't cause the same issue that the sky boxes do.

Any thoughts, even though the issue can be resolved by turning those into devices that only connect via wifi.

90 Mbps is near the max when it's syncing at 100Base-T. Maybe a faulty cable/connection is causing the switch to drop down to 100Base-T on all ports not just the one port with the faulty cable/connection. I'd confirm all wires in all cables on each end are connected in the right order and reterminate them incase they have come loose.

Thanks.
I'm going to get 2 or 3 pc's and connect them up at the different sockets all at the same time and if it does the same thing then I go with the faulty cable/connection. I've looked at the plugs and sockets and they are all T-568B
 
I'd suspect the cables. It could also be a faulty switch or it's power supply. Try power cycling it if you didn't already and a different power supply if you have one.

Just tried the TP Link SG108 and it did the same. I'll relook at all the cable and reconnect.
