SSH onto the machine and run:
uname -r

Note the kernel version.

then, google for kernel-devel (kernel version)

Case Study – Router Upgrade – from 8Mbps to 200Mbps

We were approached by a client in central London to help with their internet connection. Although they had upgraded to Virgin Media’s 200MB/s DOCSIS3 service from a standard ADSL connection, they were still getting poor broadband speeds.

Old Hardware

As soon as we visited the site, the problem became apparent. They were using a Netgear FVS318v3 – this is a very out of date unit, that has a maximum throughput of 11.5Mbps. See the technical specifications here for a blast from the past: fvs318v3. Click here for more details..
