Hello dear friends, I have a speedtouch 780wl router.And i have some connection problems for a few days.My connection is 8mbit and when i reached the quota, it is 3mbit for the rest of the month.But suddenly my connection has almost got down.And i can not fix it.On speedtests, i can only get 0.8mbit download speed.I called my isp for two times and they send they dont see any problems on the line so it should be a router or pc error.Anyway i tried everything, formatted pc, upgrade new firmware of the rotuer and make all adjustments.Anyway nothing seem to be repaired.So i tried to make some modifications on DMT tool and i add some screenshots from it and my modem interface.Could you somebody explain the cituation to me?Is that a line or router based problem?By the way my download speed never exceeds 70-100kb/sec.Thanks.
