Zzonkers :
I range 10-15mbps on speetest.net
I have a gigabit mobo & router but a 10/100 switch that I found. Would be nice to have more hardwired connections in my room. Would I notice a difference at the download speeds? Sorry I know nothing about networking.
10baseT Ethernet is 10 Mbps
100baseT Ethernet is 100 Mbps
Gigabit Ethernet is 1000 Mbps or 1 Gbps
Because of the way data is put into packets, these work out to approx 1.25 MB/sec, 12.5 MB/sec and 125 MB/sec respectively. Gigabit speeds are further constrained by whether or not something called jumbo packets are supported. Without them, you may only see about 30-80 MB/sec.
Note that 10bT dates back from the 1980s, and it's incredibly rare to find hardware which doesn't support at least 100bT. The 10/100 on your switch means it supports both 10bT and 100bT.
If all you're doing is accessing the Internet, a 10/100 switch is more than enough. Where gigabit ethernet typically helps is when you're transferring files between computers on your local network. Hard drive read speeds top out at about 125 MB/sec, which is right around the theoretical limit for gigabit ethernet. (SSDs go up to about 500 MB/sec for sequential reads, but if you're copying a directory with a bunch of files, 50-150 MB/sec is more likely. We're not quite to the point where 10 Gbps is that useful in the home.)
