i have a cisco 857 router and i need to upgrade the firmware from 2.5.something to 3.0.something else
the modem bit of the router drops out frequently and i'm led to believe a firmware upgrade will fix this
instructions on the 'net tend to be along the lines of 'download .bin' - OK no problems
'rename to adsl_alc_20190.bin' - OK too
'copy to flash and reboot ' - ??????
if i dig a bit harder i can find stuff like 'use your favourite tftp server ' - ?????
for me that's a bit like saying - 'for coronary artery bypass surgery, open chest, fix arteries, close chest'
can anyone walk me through the process please
i have the correct .bin, renamed and saved in c:\local software on my laptop and i can log into the router using hyperterminal
what next ??????
