***SOLVED*** Getting half the speed on my network configuration

[vincentpersichetti]

I've searched and searched but alas I am breaking down to ask why this happens.

Modem->switch->router->pc = ~211mbps
Modem->router->switch->pc = ~90mbps

Switch - netgear GS105
Router - netgear R7000
Modem - ARRIS SURFboard SB6141 DOCSIS 3.0 Cable Modem

So here is why this is important to me. I want to connect my smartTV (Samsung UN55D7000) to the internet via ethernet (because of wireless buffering problems) and if I connect the tv to my switch it won't connect to the internet. But if I connect it to the router, no problem for the tv. My office is upstairs and my tv is downstairs. Everything is connected via CAT6.

Obviously there is something I'm missing. I so confused why the switch won't give the gigabits
when I put it after the router. I appreciate in insight you all can give me.

***FIXED***

So IPv6 was disabled on my router. When I enabled it (it automatically detected "6to4 Tunnel" <whatever that means> as my internet connection type) and I enabled "Use DHCP Server" my switch quickly changed to gigabit connection and I got speeds of ~180mbps from speedtest.net.

Thanks for everyones suggestions. I couldn't have done it without you all!

Just for a test... What if you did Modem -> router -> long cable upstairs -> switch -> PC ... What do the LEDs on the switch say the link speeds are for the PC and the switch to router ?

"Modem->switch->router->pc = ~211mbps"

This is an incorrect config.


"Modem->router->switch->pc = ~90mbps"

This is a correct config.



1. What speed do you pay your ISP for?
2. How are you testing this?
3. Is this wired or WiFi?

This is my this is my exact configuration I get the light only on the hundred megabits per second

From router only 100mbps light. To computer 10/100mbps lights (1000mbps)

It sounds like something is set to 100Mbps in there.

When the modem-> router-> switch->pc setup the lan port that the switch is plugged into is amber (not a gigabit connection). When it's the other way (modem->switch->router->pc) the router recognizes the switch as a gigabit connection.
