Ok so i know n00b mistakes were made as i post this but....
Recently got HG659b modem in prep for fibre install, while i managed to change the config file to change the ip's for guest network (which i'll never use) as my network uses 192.168.2.* (as the vpn i connect to uses 192.168.1.* and since the guest network uses that, managed to sort that out....and the i prob should have left it at that but you know once you start tinkering with things and since it has no real option (at least by defualt) to add accounts to manage the modem
Started to look into that, thought id done it correctly uploaded it to modem and since then has kind of messed stuff up tried hard reset, to no avail then found out about rescue mode for firmware
got ahold of the correct firmware for it just now and seems to have flashed properly but i feel i may have made things worse and now it doesn't seem to have done anything...am i missing a step(s) after it successfully flashes? network still appears as unplugged so obviously something is wrong (i kept the original conf file on hand), set to dhcp and again no avail?
