GS308E Speed Issue
I have fiber from my ISP. The line coming into the house is connected to a orbi Wifi router. There is an ethernet port on the orbi router that I have plugged into my GS308E ( managed ) (into port and I can see that the speed coming into the switch is 1000M but the two connections I have out to other PCs in the house are only showing 100M (set to auto) and there is no option to select 1000M. what is the solution to fix the issue. Im using Cat 8 cable to connect the switch and the LAN cables . I tried settings on switch and also on router all seems to be set okay , not sure what am i missing here.

Do the PCs show 1000 when connected directly to the back of the Orbi router?
Do other devices show 1000 when connected to this switch?
What is the brand and model# of the ethernet adapters installed in these two PCs?
Make sure all ethernet drivers for these adapters are up to date in this two PCs from the enterner adapter Mfr.
Check the advanced settings for the ethernet adapter driver to see if any advanced connection link speeds can be set. Most have this option.
What is the model # of the Orbi router?
Yes when connected directly to the PC it shows 1000 , ALl cabled are connected and i see the networks is up and running .

The IEEE standards require Ethernet link speed negotiation for Ethernet link speeds starting from 1000M, this is why there is no such control.
Such a control would won't magically fix anything on the issue - or more anwer your question. The majory of issues why a link is not operating at 1 GbE (or faster) is caused by bad, wrong wiring, cabling, or poor connectors. For these link speeds, four pairs are required. In case one of the four pairs isn't correctly working, only Fast Ethernet (100M) - requiring only two cable pairs - is workable.
Not a switch problem at the end of the day....
On top my existing issue i strated to get a different issue,
I managed to connect the router with the switch and getting 1000M but whe the system is left idel for some time and it starts to drop the speed to 100M again , i have to unplug and replug the cable again to get back the 1000M speed again , its an managed switch and i tried to check the power cycle and other settings and eveything seems to be okay , i dohave other 305 switch connected to the same router and seems that is also behaving the same ( falling to 100m when left idle) . So i believe im missing some setting on the router itself which is causing the issue.
Modern PCs, notebooks, media players, even devices which can be activated by Wake-on-LAN can demand lower power link states, like Fast Ethernet (== 100 Mb/s), which is perfectly sufficient to keep the connectivity up - these are all mandetory power saving methods required nowadys. Once the full speed is required again, GbE (1000M), or where available on more expensive equipment 2.5G, 5G, 10 G (as well s 25G or 40G!) will come up when required.
Disconnecting and re-estblishing the Ethernet link (including restarting the PC, appliance, ...) will of course bring up the link on the re-negotiated mximum allowed link state again - until power saving will jump in again.
There is no control you have missed - this is intended operational behavior nowadays.
Agree, to the unexperienced user, this might look strange if starting to monitor thier newer network equipment.
