In the Upgrate Doku is the notice copy with tftp the Firmware to the Flash then reboot the Router.

I do this but i have the old Firmware version on the Modem`s and not the new firmware please Help

Re: C3600 Modemfirmware

Most likely you have Mica modems (digital modems) because you have modem firmware 2310..fw.1.2.2.bin is for Analog modems.

Pl. verify that using command

sh modem version

Now to upgrade the mica modems, you need to download the (recommended)firmware 2.7.3.0 (mica-modem-pw.2.7.3.0.bin) from the location
