About a week ago I tried to use firmware HyperWRT2.1b1 tofu12 At the time my current firmware was Linksys 4.20.7 I ended up 'bricking' my router and with the help of a Linksys tech, got my router back online. I now have latest firmware from Linksys ( 4.20.7 ) but would like to try again.I was told that the reason I failed last time was that HyperWRT2.1b1 tofu12 did not support my current firmware ( 4.20.7 ) if true or not, it didnt seem to work. I was told to try another.So here I am asking for suggestions on firmware and a guid on doing it so I dont mess up my router again. Reason I want to change is for BT and from what is said, official Linksys firmware is messed up and effects BT in a bad way. Thanks in advance!
