D-Link DSL-2740B-not connecting to WAN
« on: April 22, 2014, 06:23:20 PM »

I have problem with D-Link DSL-2740B (firmware EU_5.17). If my router lost synchronization few times, it doesn't connect to Internet (synchronization is established but it is not logged in WAN). It is necessary to reboot in order to connect again. What is happens?

Best regards

>> it doesn't connect to Internet

That means its not automatically getting a PPP session.    There may be a setting that you need to change, although someone with more knowledge on that router is possibly best to answer... some routers are better than others at regaining PPP after a loss of sync.  It may have something to do with timeout settings... but wait for someone who knows more on that router..  because I dont know your router and have no idea of its config.

I can't remember the details for this particular router, but they usually have options for the PPP connection timeout and reconnecting automatically. But if I can make a suggestion, your very good connection shouldn't be re-syncing frequently. If you're still tweaking the target SNR margin to a very low level, then you should stop doing this and reset the target SNRM to a level which maintains the stability of the connection.

I don't have resyncing unless my ISP and myself check something. On SNR margin 0.1-1.1 dB I had resync after 7 days. Reconnecting to PPP sometimes work and sometimes not. However, click "apply" in PPP settings help. "Connect" doesn't help.
