TG585v7 does not have any updates released for the router and there wont be any anymore.
Got the same problem here, speed goes down from 850kbs tp 200 and even 60kbs after 1pm. Can somebody from KC explain?
Guessing your on MAX? The reason for the slow down is that KC are been tight with the ammount of bandwidth they allocate to the MAX packages.
This means theres a higher contention ratio for the bandwidth and as such downloads are slow as more people start to use the net.
