Having used this router for a couple of years I have found that Netgear's F/W updates haven't been that great. Latest version I have used successfully is 1.0.28 and tried x.x.54 (wifi drops) and then 60 and 62 with similar issues though the latter need fibre modem rebooted I find to get internet working.
Am back on x.x.28 but wifi dropping now and wonder if this is due to the GUI version showing the highest version of 1.0.62 even though it clearly shows the rather 'vanilla' GUI? Reverting F/W works but any idea how to revert GUI or failing that a cheapish router with good wifi range. VOIP would be nice but not essential.
