For the last few months when I reboot the TM-AC1900, it will not allow clients to access the internet, even though it says it is connected on it's admin page.
- Factory reset
- Go to router 'Port Mapping' page and add a port mapping.
Clients can connect to the router but can not see the internet.
A temporary work around is after rebooting, go to the Port Mapping page and simply press 'Apply'. The router will then allow clients to connect to the internet.
This workaround is no good for the long term - as any power outage or something else that causes a reboot will cause it to go back into the bad state. My family will not be able to use the connection until I come to fiddle with the router admin pages.
Other users are seeing this too:
These have been marked as "assumed answered", although nothing was actually done, and the problem is clearly still there. So I am starting this thread to hopefully get satisfactory resolution.
In the former thread user casadelgato states he has the problem also, he called T-Mobile support who put him through to ASUS support. He was told it is a known problem in the firmware and an update from T-Mobile is needed to resolve it.
This bug was not present in the firmware that originally shipped with the router, it is a regression. Can we get an update please?
