Internet connection fails after ~24 hrs

[dbsseven]

I have been having a consistent problem with my Almond+ in that every ~24 hours I cannot connect to the internet anymore. I am connecting to Time Warner Cable through a Ubee cable modem. If I unplug/replug the router or the cable modem it'll work. Everything on the A+ and computers say the network is up, and connected to the modem, just no connection to the internet. Windows suggests a DNS error.

I have left all the settings as default. Any suggestions.

Apologies if this has already been discussed.

I have the exact same problem after applying R67.  R66 had Wifi issues for me, R67 seemed a lot better, but all my clients lose internet connectivity.

Interesting enough, when I ssh into the router, the router can access the internet just fine.

Help!

Please try R069 - http://forum.securifi.com/index.php?topic=2229

[dbsseven]

I have tried up to R069. A bit more detail. The device appears connected in the touch screen but in the web interface there is no IP address. Resetting this in OpenWRT or the Almond+ software fixes this.

I am getting the same problem. I am on Time Warner Cable also.  I get an error in the OpenWRT  System. Logs   udhcpc

I have the same issue with router disconnecting from internet every now and then. Unplugging & re-plugging the LAN cable between my modem(6141) and Almond, fixes it temporarily until it happens again..

Internet provider: TWC
Modem: SB6141
Almond + FW: R069

Very frustrating issue to deal with every day..

Update your firmware with R070, you can update through LCD UI.

[rag1998]

Upgraded, will let u know how it goes..

[rag1998]

Sadly this update hasn't fixed the issue for me..All devices on the network are still able to connect to Almond + but there is no internet. Unplugging and replugging the internet cable/reboot fixes the issue, but only temporarily..

This is what I see in the logs when this happens: (but I also see this when the network is functioning fine)
Feb 14 06:54:42 AlmondPlus user.info sysinit: The source address 10.10.10.145 for group 239.255.255.250, is not in any valid net for upstream VIF.

I also have some logs that I was able to capture from the server, can send via PM/email, but not quite sure if the disconnect event has been logged anywhere as it happened in the middle of the night!

I have my Almond+ router working on TWC internet.

Internet provider: TWC
Modem: SB6183-9.2.0.0-GA-03-29-NOSH
Almond + FW: R070

Log into your cable modem

http://192.168.100.1

Copy your Status Downstream Upstream power levels.

Also in the Almond+ Realtime Connections look for a ip address of 142.254.213.x  !!
This is the TWC  Dhcp Server.   (my area TWC DHCP Server address is 142.254.213.73 )

To fix the problem try these Firewall rules below. Cut and paste to  Firewall - Custom Rules ..
Also change the x in the IP address to the correct ip for your area.

This happened to me wih the new firmware and extender mode.  Reboot has solved the issue so far.

Interesting, have reached out to securifi support and hope fully there will be some insight into the issue here..In the mean time I might give your suggestions a try to see if it fixes it!

You may also setup up an auto reboot crontab.

Go to OpenWRT

1:  OpenWRT
2:  System
3:  Scheduled Tasks
4:  add new rule

0 5 * * * reboot

This will reboot your router at 5 am every day..  You may change the 5 to what ever time you would like it to reboot.

Every time you reboot you router you also have to setup your Timezone. This will reset to UTC time zone when you reboot your router.
To reset your time zone go to openwrt

1:  OpenWRT
2:  System
3:  System
4:  Timezone
Change to your timezone

This issue is happening to me since I updated to R070, before the update I never had such issue.

It uses to happen at night, connection works fine all over the day, but when I wake up I have a no internet connectivity warning in all my devices (PC and Android). By entering in Internet connection and reapplying the PPPoE settings, the issue is fixed for another 24h (more or less).
