Temporarily Repair Your Home Internet After a Cable is Cut

I’ve been having some landscaping work done in my yard, and despite having all of the utility lines marked, the crews have managed to cut my cable internet line on several occasions. Since I work from home, and we don’t have hardly any cellular reception at the house, it was pretty devastating. I couldn’t even call the cable company to repair it without driving somewhere with better reception.

So when they said it would be a few days to get a technician to come and repair the cut cable, I decided to try out some repairs on my own. I happen to have some coax crimpers, spare cable, and ends at home, so I first attempted to terminate the cut ends, but the direct-burial cable that is used outdoors is quite a bit thicker than indoor cable, so my ends and crimpers wouldn’t work.

Without any of the correct tools, I was left with just the most primitive of methods: simply twist the center wire together with some needle nose plier, and tie them together with wire ties.

Here’s one of my first attempts when they cut the coax. I tied it into my own coax and which ran back to the house. On this first attempt, I tried to leave some extra shielding and twist that together from each end.

A subsequent cut, with newer cable had enough slack that I could just tie the two ends together directly. After it was repaired, this is what the technician left so you can see how I first twisted the ends together as much as I could with some pliers before adding a wire tie onto it. I just cut the shielding clean off and didn’t attempt to mess with it, which still resulted in it working fine.

It didn’t result in the full 200 Mbps+ speed that I should be getting, but 50+ Mbps was absolutely better than nothing for the few days until the technician could come and re-terminate the ends properly:

Installing snmpd on Ubiquity Dream Machine Pro

I was surprised that the Ubiquity Dream Machine Pro doesn’t have SNMP available. I recall that there was an option to enable it in older versions of their software, but the current 3.0.20 version doesn’t even have an option to enable it (and I don’t think that it worked correctly in previous versions).

Fortunately, its basically just a Debian machine, so you can enable it yourself! These are the steps that I took to enable snmpd so that I could add it to my network monitoring system:

First, update the respositories and install the snmp and snmpd packages:

apt update
apt install -y snmp snmpd

Then, you have to edit the snmpd.conf file in /etc/snmp/snmpd.conf and change these two lines from the View section. This change makes it so that instead of providing information only about the host system, it provides information about all of the attached interfaces as well.

view   systemonly  included   .
view   systemonly  included   .

To these two lines (note you remove the final .1 from the end of each).

view systemonly included .
view systemonly included .

Also, you’ll probably want to configure the snmpd deamon so that it will be available on a local network interface, so change the agentaddress line to this (obviously, with your box’s IP address if it isn’t


Then restart the snmpd deamon

service snmpd restart

You can test that it is working by running snmpwalk with a command like this:

 snmpwalk -Os -c public -v 2c

Which should output hundreds of lines of stuff that start out similar to this:

brandon@auvik:~$ snmpwalk -Os -c public -v 2c
iso. = STRING: "Linux dream-machine-pro 4.19.152-ui-alpine #4.19.152 SMP Thu Apr 6 21:41:48 CST 2023 aarch64"
iso. = OID: iso.
iso. = Timeticks: (377603) 1:02:56.03
iso. = STRING: "Me "
iso. = STRING: "dream-machine-pro"
iso. = STRING: "mycommunity"
iso. = INTEGER: 72
iso. = Timeticks: (0) 0:00:00.00
iso. = OID: iso.
iso. = OID: iso.
iso. = OID: iso.
iso. = OID: iso.
iso. = OID: iso.
iso. = OID: iso.
iso. = OID: iso.
iso. = OID: iso.
iso. = OID: iso.
iso. = OID: iso.
iso. = STRING: "The SNMP Management Architecture MIB."
iso. = STRING: "The MIB for Message Processing and Dispatching."

If that works, congratulations! You’ve got snmpd installed on your Ubiquity Dream Machine Pro. Your network monitoring system may take a little time for it to notice that SNMP statistics are now available on the device.

Note that upgrading the device will probably lose these configs and they’d have to be re-done.
