Disconnection Issues Since Updating Firmware

[BENBOBBY]

Ever since updating my firmware to Asuswrt-Merlin a few days ago Ive been having disconnection issues. It might just be coincidence, but strangely it seems to occur around midnight and only once! Although this is typically when I am also doing the most downloading/streaming.

The disconnection error message comes up and advises me to run the connection wizard, which I do but it says it cant detect a connection (wired and wirelessly). However if I go turn the MODEM off at the wall for a few seconds and back on then it all connects fine again.

I live in the UK and my ISP is British Telecom (BT) and have the 'Infinity' - fibre optic broadband service. I have a modem provided by them and an Asus RT-AC88U router. I havent altered my settings since the firmware change and have connection type set as PPPoE with a MTU of 1492 as shown below:

Since it occurs at around midnight Im wondering if perhaps theres some sort of time setting thats out of sync or when the dynamic IP changes perhaps??

Thanks for the help

Thanks for the reply. Im surprised to hear this firmware gives such problems, I thought it was supposed to be an improvement on the official one!

Ok so I copy and paste the script in that thread you mentioned into notepad and save it as "wan_check.sh" on my USB stick connected to the router. However then how do I actually run the script? I assume I need to connect to the router via PuTTY then type in:

#!/bin/sh logger "WAN Up: New IP address is $(nvram get wan_ipaddr)" killall wan_check.sh /mnt/myusbname/wan_check.sh &

?? Sorry all this is new to me. Will having a script run constantly in the background effect my routers performance?

This tells exactly howe to configurate this.

Save script on usb or /jffs
Start: started from /jffs/scripts/wan_check.sh
make it executable:
chmod a+rx /jffs/scripts/wan_check.sh

Put this in: /jffs/scripts/wan-start

#!/bin/sh
logger "WAN Up: New IP address is $(nvram get wan_ipaddr)"
killall wan_check.sh
/jffs/scripts/wan_check.sh

make it executable:
chmod a+rx /jffs/scripts/wan-start

it will check if wan is down and "renewing dhcp wan"

Yeh it tells you how if you know what any of it means! Thanks for the reply, but how do I even save the script to /jffs I cant find the folder?

Download WinScp and config your connection to your router.
Then you can find /jffs.

I have PuTTY if that does the same thing?

no


Just a thought, did you factory default after upgrade and put config back by hand?
If not, it may be the problem

 

[BENBOBBY]

Ok I tried resetting everything back to factory settings, then reapplied the settings manually. Still disconnected tonight unfortunately.

So I downloaded WinScp as suggested and put the wan_check.sh file into the /jffs (and /jffs/scripts) folder. Then loaded up PuTTY and typed in the 'chmod a+rx /jffs/scripts/wan_check.sh' command you said but nothing seemed to happen. Ugh :/

Can anyone help please?

Hi
I am facing similar issues of sporadic loss of internet. I am wondering whether this script would work with a PPPoE setup (as the screenshot at the top seems to imply)?
Just asking so as I recall a post by RMerlin on another thread saying that dhcpc events would always fail under PPPoE.
Can anyone shed light on this? Thanks
