Question Transfer speed on LAN

[ForeverNoob]

Hello,

My home LAN includes a PC and a NAS drive, both wire connected to a 1GBPS switch that is connected to a 1GBPS router. My question is: If I replace the router with a new one with a 100MBPS LAN, will the data transfer speed between the PC and NAS drive going to drop?

TIA

No, as long as they are both connected through the switch, they will remain at GbE link speed.

I wonder why you would replace a router with GbE ports, with one having only 100Mb. GbE routers have been around a long time and so aren't expensive today. People are even giving away old used ones with GbE.

Thank you.

It is because where I live the WAN infrastructure fails frequently, so I consider buying a router with 4G cellular support, but I was only able to find one in a reasonable price with a 100MB speed.

Still more then twice as much as the one I found.

If I can maintain hi-speed data transfer to/from the NAS then this is good enough.

Thanks.

As @mindless1 said, you can maintain 1Gbps between PC/NAS as long as both devices connected to the gigabit switch, your internet just can't go over 100Mbps if your subscription rate is higher than that.

Yeah, 100MB is what I get from ISP, so it's supposed to be OK.

If your speed tier is 100Mb, a 100Mb switch/router will bottleneck that due to inefficiencies to around 90Mb IIRC.

I can probably live with that. https://www.speedtest.net/ indicates around 75MB on a good day, so 90MB should be OK.
