My ISP has upgraded my line speed from 1 to 2 megs. My Netgear router model DG834Gv3 shows in its menu screen that I am achieving the correct speed 2272 downstream. Checking my connectivity software and running tests on a number of download speed test sites shows figures averaging 800499 kbps 1 meg. Various posts suggest in the routers advanced settings Wan set up changing the MTU from 1450 to 1400. Once or twice taking this step I have noticed an increase in download speed to 2 meg then the figure readjusts to the lower speed. Can anyone suggests further steps I can take to resolve this problem?
"A DSL router should not be set more than 1498 MTU it can slow or stop the router."
Do you have any evidence to back this up?
My ISP recommends a MTU of 1500, using other than this can limit the speeds. My router is set at 1500 as are my PC's, no slowdown here.
"CyberTweak is a Tweaking app for Windows. It changes the default values provided by windows to optimum levels for fast internet access." This application changes the Windows settings but not the MTU value for your router which can only be done via the routers interface.
