Internet Keeps going down
-
I do have a nice Cisco switch that i could put between the modem and the router. I cannot see any admin pages on the modem. I could if it was in "gateway" mode and acting like a router but since it is in bridged mode, it is just acting like a cable modem, cannot get into it I believe, i have tried.
-
There should be a way to get into it… Otherwise how would you change it back to gateway mode?
Do you remember the old address it responded to?
-
pretty sure the only way you can get back into it is to factory reset it with the reset button on the back. It used to respond to 192.168.0.1, now that ip is unreachable.

http://192.168.0.1:8080 work?
Im reading the manual now…
-
let me check when i get home, just at work now. would be very helpful if it did. was able to get the other computer up and running before I went to work today and I think the internet went down before I even left for work. will have to double check when i get home. thanks for your replies and trying to help guys, I REALLY appreciate it.

Cool- Good luck!
Im watching a video of a guy accessing his in bridge mode and showing how he did it so I know its possible. You dont have any LAN rules preventing the connection do you?

I had some port forward rules before to try to get my VOIP phone working but have since installed with just the default PFsense rules, haven't changed a thing for a bare install.

Ok– will wait to read your progress later.

thanks so much man, about 8 hours :)

I have a few questions:
1. Why are you using the DNS Resolver settings, does your ISP not offer DNS? Just let it pull the DNS information via DHCP
2. Can you reset your modem back to gateway mode? For testing purposes. It would seem to me you have a layer 1 issue since you are using link on your firewalls WAN
3. Once your gateway is reset can you log into it and post the information under the ISPs network info? I'm looking for Receive signal levels, SNR, Transmit Signal levels …..At Comcast we have a similar Bridge mode and the only way to take it out is to reset the gateway by holding down the reset button for 15 seconds.
You can run PfSense from behind a NAT just make sure you uncheck the box on the WAN setup that say, "Block private networks and loopback addresses"
When your PfSense Firewall goes down see if you can connect directly to the gateway and get out that way either wireless or wired. This will let us know if the problem is happening upstream of the PfSense Firewall. Also make sure you don't have any switching loops on your network.
How if the PfSense Firewall connected to your LAN, are you using a switch, if are you using any vlans? A simple network diagram here would really be helpful. https://www.gliffy.com/

Mostly I use DNS forwarder because i subscribe to AirVPN and they have a PFsense setup guide and DNS forwarder is how he sets it up, but I haven't even got that far yet. The resolver is just the default setting for the PFsense install, I literally didn't touch anything after install. Pretty sure my ISP offers DNS but I just default installed and waited for it to go down.
I could reset it back to gateway mode for sure to test, at this point I will do anything. For number 3, yes I could do that as well.
when the firewall goes down, sometimes I can ping the firewall from my computer, sometimes I cannot. Sometimes there is a yellow exclamation mark by the network connection, sometimes not. All the time I can SSH into the console and mostly I cannot ping from there..
I posted a pic of my network above but here it is again… It is a little more complex than this but for right now, this is how it is, just keeping it basic to get this thing working..

Really would like to narrow it down to a hardware or software problem, my wife thinks I'm an idiot but I have much invested into Pfsense and don't want to give up.
-
Sloooow down a bit… One step at a time.
Try the switch and lets see which interface is actually dropping when you lose connection.
-
@chpalmer for sure, i want to be methodical in doing this.
how did you want me to wire up the switch to test? just cable modem wan to switch, then one port of switch to wan of pfsense and another port directly to another Pc?
-
I will standby in read only mode. If/when you determine its your modem it looks like when you put it back in gateway mode, at the login you should get the numbers I requested.
-
thanks Mike, appreciate your help very much.
-
Put it in series. Modem - Switch - Router. If the connection goes down again then you will see which interface drops independently of the other.
Mike- you saying you can't reach your modems GUI in bridge mode either? Really makes no sense to me as cable is not a "tunneled" connection like a PPP or VPN connection would be. Notice that modem in the video I linked to is in bridge mode already as the user is showing the options…
The firewall does not by default block connections outbound to 192.168.0.1 unless you are using 192.168.0.0/ as your LAN as well.

like this? sorry for the crude drawing..

You dont need the PC on the switch.
-
i would just be able to tell because the lights on the switch?
-
Yep- thats the idea. Otherwise you could try putting 192.168.0.(2-254) in your laptop as a static IP and see if you can reach the modem while plugged into the switch.
But since you reported that the interface lights also go out during these occasions this should tell you which device is doing it.
