I'm getting the same error message as others when updating from 58 to 59 on my RT-AC66U. Here is the message:
Firmware upgrade unsuccessful. This may result from incorrect image or error transmission. Please check the version of firmware and try again.
I never had this error before. Just in case I tried other browsers. Same issue.
Restoring anything after a factory default rest mostly reverts the benefit of the factory default reset.
The GUI is painfully slow on Safari (OS X 10.11.4), but is fast and snappy in Chrome. I never had this issue with 380.58 or previous releases.
I"m taking this as NO NVRAM restore, put everything back in by hand?
factory reset yes, manual input of values... web UI still not show "Allow SSH access from WAN" set "No"
Any chance of retrofitting Smart connect from AC3200/5300 to say the AC68U?
It was working properly before 380.59. Any idea what could have been possibly "improved" by Asus that it doesn't work properly now?
Upgraded today RT-n66u 380_59 Has made the connection unstable Constant Drop Outs with Internet connection Had to revert back to 380_58
That still doesn't really explain why my IP phone won't receive all incoming calls anymore, as soon as the NAT helper is enabled. But since it's now working perfectly fine with the SIP passthrough enabled without the helper, it's probably not worth the time to keep wondering about this.Linux's Netfilter will try to detect when something is a SIP connection, and when it does, it will try to automatically handle inbound traffic, bypassing the firewall. Some provider might need it, others don't as they have other methods of traversing through NAT.
