how do i upgrade cisco router firmware ?
hi
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
however .....
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 ??????

thanks - once i worked my way around the laptop firewall and worked out #copy tftp: flash: was what was needed.
router now works -TA DA

It sounds like the router could not open the connection.
1) make sure the tftp server is active. I would go into more detail, but it depends on which tftp server you are using.
2) make sure you are not running a local firewall.

the .bin is in c:\tftp\
tftp server is listening on 192.168.10.7:69
telnet into the router with hyperterminal and i get this ...

cisco857#copy tftp: flash:

%Error opening tftp://192.168.10.7/adsl_alc_20190.bin (Timed out)
can't see why that should be happening !!
