Dear all,
i have some problems with my c897vaw vdsl router.
1. All clients that are connected with 5ghz wifi have network/internet access for a few seconds,
then they stay connected to wifi but they are unable to access anything to local lan or internet.
Whenever i change channel to dfs or any other frequency the have network access for a few seconds.
In 2.4 GHz they have no problem.
Which debug commands should i execute (router and/or access point) in order to collect the logs ?
2. vdsl line wont sync anymore after tha last rain storm,
my old backup 887vaw syncs just fine . I changed ios image and firmware but nothing changed. No sync
3. and last while i reload i get the message "Feb 6 10:36:57.000: %MAINBOARD-3-RTC_BATTERY_FAILURE: Real Time Clock (RTC) oscillator problem detected, possibly caused by RTC battery failure"
the battery is soldered to mainboard, can i somehow change it ?
thank you in advance,
Manos

when ever you change wireless settings, sometime clients discconnected that is normal
but if the wireless connected and you can not access Internet (are you able to ping gateway ? what is also not working ?)
what logs you see on the device when you disconnected the device. make sure you configure logging to get logs.
