My specs are a mid-2010 iMac with a wireless 802.11n connection. Service is FTTC up to 76mb with an estimated speed of 55mb. I rarely get higher than 30mb, often 20-25mb on various speed tests.
This evening I was getting this shocking throughput. I initially thought it was Plusnet so posted a comment on that thread. Was advised to plug the Mac directly into the router and run this speedtest again. This time it jumped to this.
After spending months thinking Plusnet was to blame it turns out to be my wireless connection. Keeping the Mac wired to the router is a bit impractical, but is the Mac the weak link in the chain or the router?
