Can a router affect internet speed?

I bought a roku , at my parents it worked great. I brought it home and it was reloading every 5 mins my computer speed it quicker than theirs so I was wondering if it was my router.
Thank you.

It could be the router, or the placement, or poor wireless signal caused by interference, distance or even the walls.
Do you use any other devices wirelessly?  Do you have the Roku a fair distance from the router?  What kind of construction is your house?  Thick stone walls are really bad for wireless transmissions, equally if you have any metal in the way that'll do a good job of stopping the transmission.

It's in the same room at the other end. No walls in between. I have a tablet and 1 computer and netflix in the bedroom. It was better today but now that it's evening it's doing it again. My son has told me before that he thought our connection was worse in the afternoon. Is that even possible?

More wireless devices being used at once can clog up and slow down a wireless connection.

A very simple test for this is to plug an Ethernet cord into your computer and run it directly to your Modem.  Do a speed test at www.speedtest.net before and after you run the cord to the modem.
