Can't fish Ethernet? Use "invisible" fiber instead

By · Published by Everything Blog

In short

The resident tackled degraded connectivity by mounting a 20-meter fiber line between floors using removable adhesive instead of permanent superglue. Hardware components including an existing MikroTik switch, media converters, and bidirectional SC SFP+ transceivers successfully linked the line to an HPE AP25 access point. This configuration boosted local network throughput to approximately 300 Mbps. The discreet project prevented potential wall damage around a $1,500 television while avoiding the expense of hiring a contractor.

My family owns a NYC townhouse, and with that I had Cat6 cables put in on each floor.

However, more recently, one of the Cat6 cables has gone “bad,” meaning it only does 100 Mbps. While we are nowhere close to Gigabit speeds, very less multi-Gig (despite me having had symmetric Gigabit in the past), it’s still not something I’m happy about.

What do you mean only 100 Mbps? My switch and AP support 2.5 Gbps.

The most common approaches in my scenario are:

- Fish a new cable

- Abandon the cable and use wireless mesh

However, there are a few issues:

- The cables were fished in a funky way, and considering how clumsy I am I don’t want to cause more damage

- Our walls are thick, meaning wireless mesh would suck

When I did use mesh on HPE AP25s (the APs I use), the performance was 120 Mbps at two prior homes, that with thin walls and fiber. I also want VLAN segmentation so a typical consumer Eero or Orbi won’t work.

So what did I…
