Hello My all in one package from KPN got installed today, I noticed that my download speed was very slowly only around 1 MB. While I have a package with a internet download speed 25 MB, so I logged in to my router and look at the connections and indeed it was receiving and average download speeds a bit less then 25 MB. But it was receiving alot more then what my computer was receiving, so now I am wondering how can my router receive almost the full connection and why is mine computer only receiving around 1MB. My computer that I am using is connected straight with the router with a network cable. The same applies to my wifi it has the same problem also around the 1MB download speed. Does anyone have any idea what this could be or how i could solve it ?
