Hi renluop
Your wireless connection is pertinent to this issue and a few others
Using wireless, if there is a break in wifi, it can cause floating point issues etc in dslstats.
I use wifi, and have seen a floating point issue after wifi had an issue
I have never reported this though, as the only advise I have seen for dslstats, is to use hardwire connection only, no wifi (guess that means wifi not supported due to issues wifi could give, which are not a result of dslstats)
I hope that helps a little
Many thanks
John
