how to check the ISP bandwidth
 

I'm using WiFi at home
there is a wireless router which my laptop connects to

I want to know the uplink and downlink bandwidth that the ISP provides to the wireless router

are there any commands or tools that I can use to get the bandwidth value?
thanks

There are lots of speed check sites, most are ISP's that provide speed checks. Here is one link

If you google 'ISP speed check' you will turn up many more. You do not need any special tools. I usually will check results with several providers, they usually are close enough, and close to what my ISP says the service will provide.

One of the best is shaperprobe. Besides measuring your maximum burst speed, it also detects and measures traffic shaping (where you get a large rate for a certain number of bytes and a lower rate thereafter), telling you the approximate burst size and the final rate you get. The Linux version comes as a .tgz source file from which you compile the (small) executable. It needs no libraries other than glibc.
