D3600 loses all settings

hi there

 

 this is a follow up to https://community.netgear.com/t5/DSL-Modems-Routers/D3600-Loses-all-settings-no-internet/td-p/111215...

 

 

I have gone through 2 units of D3600 and both have been updated to the latest firmware .

 

Set it up, let it run for 4 to 6 weeks and all of a sudden, internet drops off and all settings are lost. 

I will need to restore settings from backup.

 

Why is this happening?

 

Also, with one of the D3600 units, I noticed that when i reboot by means of shutting down the power and turning it on again, it loses settings. Really wondering why isn't there a power on and off button on the unit but that's a side issue.

 

 

Anyway, anyone with any more ideas?

 Netgear admins - could you guys look into this?

In my opinion there is bug in last firmware. Probably there is issue with XML settings with invalid character (see at WiFi 5G password setting or type of encryption ), so after reboot this settings are restored to factory defaults.

   That would not amaze me. In 2015, I got a DSL speed increase, and
found that my old (but otherwise reliable) Cisco 678 was my new
bottleneck.  A (bargain-Ebay) DGND3700v2 had a better DSL modem, but
that router's port forwarding demanded identical external and internal
port numbers, making it useless to me.  Encouraged by some pre-sales
discussions with Netgear, I got a (bargain-Ebay) DGN2200v4, which had
worse wireless capabilities, but more capable port forwarding.  Sadly, I
found that with the DGN2200v4, I could get a green DSL LED, but only a
red Internet LED.

   A second DGN2200v4 behaved the same way, and firmware updates didn't
help.  Netgear "support" was of little value, but I did guess the cause.
My DSL password contained a UNIX-shell-special (XML-special?) character,
something like "abcd<efg".  If I specified it as "abcd\<efg", then the
problem disappeared.  I've since moved on to a different ISP with a
different, less exotic DSL password, and then to a D7000, so I've lost
track of whether the original DGN2200v4 problem was ever fixed, or if it
affected other models.

   The point of the long, dreary story is that Netgear firmware can't be
trusted to cope with exotic characters in user-specified data.  If a
user-entry can be corrupted internally, it's easy to believe that a
saved-and-restored datum could be corrupted, too.
