about adsl router and how to check connection rate
I noticed on some papers, it is written that:
(A) 100Mbps wired connection connected to the internet through a 500 Mbps link
(B) 54Mbps wifi connection behind a ADSL router ， upload rate 1.2Mbps, download rate 7.7Mbps
I have some questions regarding the above description
1) for (A), are there any commands or methods to know the "100Mbps" and "500Mbps" on a linux computer?
2) I'm not familiar with ADSL router. so is it that even if a ADSL router is connected to 100 Mbps Internet via wired line, it can only provide upload rate 1.2 Mbps and download rate 7.7 Mbps, that is to say the "1.2" and "7.7" is hard-coded in the router?
