look i am really sorry but i have no idea how to use the router functionality. sorry you have been landed with someone with such limited understanding!!

can anyone help with uploading firmware using router functionality?? please?

There's a guide here:
http://www.draytek.co.uk/support/kb_vigor_reflash.html#reflash

thanks but i can get the files but cannot open them! I think all round my patience for any draytek products is coming to an end!! I now need to switch off and on the router at least 3 times a day. not productive and not effective!

The files that you have if they are the firmware files would need to be used with the Router Tools, which you can get here:
http://www.draytek.co.uk/support/download/RouterTools_420_Win.zip
That is assuming you're running Windows rather than OS X or anything like that.

Once the router tools are installed, you can run the firmware upgrade utility it installs and then follow the guide for flashing the router firmware.

i have tried upgrading and get the following messages:

request time out. transfer abort!

then

you should be reset router for normal work

what next??
