We had a customer the other day have us come out to look at his new
house for a future install. The whole house is e-glass and concrete.
Interior as well as exterior walls. New concrete is wet. Between the
concrete and the eglass he had built a wifi proof blockhouse. I showed
him how bad the attenuation was from a phone set as a hotspot to another
phone in another room. Yeah he's going to be praying at the alter of
ethernet over powerlines because he put ZERO cat5 in during construction
figuring he was going to mesh the whole place.. Phone in 5 Ghz there
was barely a signal at all.. -85 from one room to another.. They all
are experts now. The most dangerous person in the world is someone with
just a little tech knowledge...

When we deploy premise routers with SFP ports, customers could care
less. Only one has ever been used, and that’s at a business customer
where we used a direct attach cable to a POE switch for their VoIP phones.
All customers want any more is WiFi. Nobody wants Ethernet. Or fiber.
What they call “hardwired” or “Earth Net”.

MAC address. So yes, could be OEM. But I asked the tech who
did the install about a week ago and he said the router name was
either Yunlink or something similar. He said that he’s seen one
more recently.

Is that what the router actually says, or just what the MAC is
registered to?

Anybody else encountered a Yunlink router?
Where do customers find these things? Are they shopping on
Alibaba? I can’t find Yunlink for sale on Amazon or
anywhere else. We’ve got a new customer with an open DNS
resolver and telnet interface. I figure it’s just a matter
of time before the DNS server gets exploited for an
amplification attack.
