I have a 5101e but its very unstable lots of lag and packet loss, I tried to put the original firmware back on but couldn't get it to work so went back to the sb5101.mod.10.2.by.fercsa.bin and while this flashes ok its still unstable and I would like to retry the original firmware again, I followed the tut to restore the 5101e previously but must have been doing something wrong as it wouldn't even let me connect to it at all any help appreciated
