BT Smart Hub & Netgear Managed 24 swtich = Slow Wired Speeds

[ramblo93]

We have a BT smart hub and FTTC. Consistently get speeds of about 28-30mbs over wifi. I recently got some cat6 installed and plugged it all into a 24 port netgear switch which in turn is plugged into the BT router.

Sometimes the wired speed over ethernet is great (30mps) but it will often soon drop to below 1mps. SOmetimes a router reboot fixes it, sometimes not.

I've tried switching the cables and see the same issue. Likewise last night i installed BT Whle Home Wifi and tried hooking up the discs to the switch via wired connections and again resulted in <1mps speeds. THis convinces me it isn't a cable issue but something with either the router or switch.

Any ideas what it might be or how I can trouble shoot to identify the weak link in the chain?

Tahnks ash = lots for me to work through there.

Another strange thing with the switch is that a couple of the ports have an orange light on despite there not being any ethernet leads being plugged in to them. This seems odd to me as usually there is no light on if no cable is plugged in. It then shows green when a cable is plugged in and a device identified and flashed green when data is being transferred...

I'm starting to think the switch might be the issue. It was pretty much plug and play (i didn't configure it with any software) so maybe i just need to do a factory reset on it and see if that fixes the issues?

If it's a managed switch it needs managing, log in to the admin console and have a look for any odd settings.

I'd test stuff plugged into the router first, that will confirm the switch is the problem.

You could also buy a cheap 4 port unmanaged switch and substitute that as a test.

From all of the p$ssing about i've done with the set up recently i'm sure I only get the issue when devices are plugged into the swtich, not when I plug into the router directly.

Sorry,, i meant it is an unmanaged switch (24 port)! Given this should i just try a factor reset on it (think there is a small reset button)?

There is no factory reset for an unmanaged switch. Simply power it off and on again.

Lights on on unused ports = very odd indeed. Never seen that in all my IT years.

I have the same set up and it runs like a dream so I think there is another problem somewhere along the line.

My netgear switch has hung up on me twice in 3 years. 3 pin reset each time clears it down.

I get solid 60-70mbps to anything I plug into the switch.

What do you mean by this? Simply turn the power off then on again?

Also when you say the same setup do you also have BT Whole Home Wifi discs connected back to the switch (as opposed to the router) via ethernet?

3-pin reset = power cycle. Pull out the three pin mains plug :-)

I will say again, your switch almost certainly is the problem. lit up unused ports is odd, particularly if not all of them do it.
