Hello,
I'm currently trying to configure an IR829GW for use as a mobile hotspot on a company vehicle, but am having an issue where I can not reach the internet through either the WiFi AP, or any of the ethernet ports.
*Cellular is configured with an AT&T sim, and appears to be functional, as I can ping out to 8.8.8.8 with 100% success rate, and the rest of the cellular setting appear correct.
*WiFi AP is currently configured with active SSID's for 2.4 and 5GHz bands, and I can connect to these SSID's, albeit with no internet access through the cellular link.
*Ethernet ports are configured and appear to be functional, as I can connect my company's business internet modem with a patch cable to any of the ethernet ports, and then I have access to the internet over the 2.4 and 5GHz WiFi AP through the GigabitEthernet ports. I can also connect other ethernet devices to any of the 4 ethernet ports and have normal connectivity/switching/routing.
Note: the cellular 0 interface appears to go down (sleep?) when I'm not trying to ping an IP, then once I enter "ping 8.8.8.8" the cellular 0 interface comes back up momentarily to complete the ping, then seemingly goes back down. Here is the cellular startup/shutdown scenario as seen on the console:
IR829#
IR829#ping 8.8.8.8
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 8.8.8.8, timeout is 2 seconds:

*Jan 27 18:01:00.113: %LINK-3-UPDOWN: Interface Cellular0, changed state to up
*Jan 27 18:01:01.113: %LINEPROTO-5-UPDOWN: Line protocol on Interface Cellular0, changed state to up.!!!
Success rate is 60 percent (3/5), round-trip min/avg/max = 140/185/256 ms

Ok, I connected a PC via GE1 and configured the PC with IP 192.168.0.10, mask 255.255.255.0, and gateway 192.168.0.2, and now I am able to reach the internet. Excellent news. I feel like a dummy for forgetting to change the IP on the connected PC's
Looks like I also made the mistake of configuring the WiFi AP with the incorrect IP, so I corrected that and now I can reach the internet over the WiFi AP as well.
Only problem now is that the cellular interface seems to go down after a short period of no activity:
*Feb 7 01:42:38.107: %CELLWAN-2-BEARER_DELETED: Instance id=0, Default bearer (bearer_id=5) in Cellular0 is now deleted.
*Feb 7 01:42:40.107: %LINK-5-CHANGED: Interface Cellular0, changed state to reset
*Feb 7 01:42:41.107: %LINEPROTO-5-UPDOWN: Line protocol on Interface Cellular0, changed state to down
*Feb 7 01:42:45.107: %LINK-3-UPDOWN: Interface Cellular0, changed state to down
Then the only way to get the cellular interface back up is to connect a PC to a GE port, and try and load a webpage:
*Feb 7 01:51:46.457: %LINK-3-UPDOWN: Interface GigabitEthernet1, changed state to up
*Feb 7 01:51:47.457: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet1, changed state to up
*Feb 7 01:52:15.125: %CELLWAN-2-BEARER_UP: Instance id=0, Default bearer (bearer_id=5) in Cellular0 is now UP
*Feb 7 01:52:17.227: %LINK-3-UPDOWN: Interface Cellular0, changed state to up
*Feb 7 01:52:18.227: %LINEPROTO-5-UPDOWN: Line protocol on Interface Cellular0, changed state to up
Is there a way to always keep the cellular interface "always on"?

that good news....but glad you were able to make all work well..our effort is paid off.
gig port (which is lan ports) you can make it switchport (so that become as Lan ports) - if I recall correctly on this models.
config t
interface giig 1
shutdown
switchport
no shut
!
if all good mark as resolved.

Ok I added that to the config. All seems to be working great now!
Thank you very, very much for all of your help sir, I really appreciate you sharing your knowledge!

Hello,
add the below to your configuration:
ip sla 1
icmp-echo 8.8.8.8 source-interface cellular 0
!
ip sla schedule 1 life forever start-time now
This will make sure that there is always 'interesting' traffic that keeps the cellular interface up and connected.

Much appreciated, thank you.
02-07-2023 02:06 PM
Thank you again to you as well sir, I really appreciate you sharing your time and knowledge!

Hello,
the access list does not look right. Make sure it looks like this:
access-list 1 permit 192.168.0.0 0.0.0.255
01-27-2023 12:38 PM
Got it, much appreciated sir.
Do I need to make that change under a particular controller/interface, or just under global config?
