This is for MacoMonday theme "all In a row". This is the lights on the front of a cable modem.

The penultimate "IT setup" in my house before I packed up my server and its external hard drives. I originally cleaned up this shelf to hold a TV, but never ended up using it for that purpose. It did work quite well holding my various internet infrastructure during my chaotic final weeks in the house. Compare this shot to the final setup consisting of just the AirPort and cable modem.

The MV setup, late 2017. It all fits neatly on an antique shelf.

Another not very good photo of my network shelf in its new ome. Compare it to a photo I took in the spring of 2022 and one from upwards of a dozen years prior.

Surviving December 21, 2012, it is high time I took a photo of my much asked about desktop workstation.

 

Been a long time coming, but here it is, my main desktop workstation and my trusty old laptop. I completed, for the most part, my system build last August 2012; I could have finished it sooner but there were technical problems that I nor my good PC buddies could figure out (I eventually figured it out myself LOL).

 

I have yet added a videocard since my wallet has gotten thin since the pseudo-completion of the build. But hey! It's the holidays... cha-ching, cha-ching. LOL

 

A normal shot with the lights on.

  

Just hover over the photo for the exact names of the peripherals, etc.

Inside of Redflex Red-Light Camera control box in Gurnee, Illinois I find it interesting that Redflex cameras take millions of pictures of unsuspecting motorists ever day, yet the repairman calls the police when I take pictures of him and the equipment.

My new cable modem! Yay!

Networking central upstairs at SHDH12.

For comparison with my previous upload of a good signal graph, here's my signal history in the last month. It's hard to see when the signal got really screwy (going up and down a lot) since things get averaged out with older data, but you can definitely see the period about a week back when my cable modem was at maxiumum transmit power for about three days (with a gap of nearly a day in the middle where it couldn't really keep a connection, so things went wobbly).

 

There's a gap just left of center when I replaced my cable modem. The old one and new one seem to read signal differently, but the new one has (in general) been more stable, even though that doesn't quite get reflected in the magnitudes of receive and transmit power.

 

I made a Perl script to connect to the little webserver at 192.168.100.1 on my cable modem and read the signal data, then ran it through the rrdtool graphing program.

 

Blue is transmit power. The red line is at 54 dBmV, which is roughly the maximum allowable transmit power on modern DOCSIS, though I think my cable modems have occasionally gone to 55 or 56.

 

The orange is receive power. This is generally supposed to go between +8 and -8 or +9 and -9 dBmV.

 

The green line is signal-to-noise ratio, which doesn't really seem to be a very good measure of cable modem signal quality, since it barely moves despite big changes in receive and transmit power.

A few months ago, I removed the previous bookcase that was in this spot and dragged in this taller one. It has a number advantages. Besides having more shelves, it has no back board, making cable routing much easier. With more room to work with, I put some books that I refer to often (in theory) as well as my humble DVD colleciton.

 

Not pictured are the bottom two shelves, which have more books and recordable media (big surprise) as well as an APC UPS to keep the networking hardware upright during brownouts and the like.

My hard working stack of boxes.

Mi escritorio limpio y acomodado para mi Netbook, mis BOSE Companion 3 Series II, teléfono, CableModem, Router e iluminación.

Motorola SB5101U cable modem that all my Internet traffic (including this description and the picture!) passes through. Taken in Albany, CA by a Nikon D40x at ISO 400 with a Nikon 18-55mm non-VR kit lens. (at 55) Camera's on-board flash fired.

 

Seen next to the ethernet switch seen earlier in my photostream, and (on the right side) a 9 Gb full-height SCSI external hard drive. (a remnant of older, no longer in service, computers…)

 

Finally replaced in Dec 2014, as the modem isn't DOCSYS 3.0 ready. (only DOCSYS 2.0...) and my cable went to the new standard. (Not that it matters, many sites, video in particular, don't stream at DOCSYS 3.0 speeds!)

Yay! I finally have a nearly flat signal graph for a whole day! Things have been so unstable in the past month or so that I've scarcely gone more than six hours without some sort of weird rise or drop in signal strength.

 

I made a Perl script to connect to the little webserver at 192.168.100.1 on my cable modem and read the signal data, then ran it through the rrdtool graphing program.

 

Blue is transmit power. The red line is at 54 dBmV, which is roughly the maximum allowable transmit power on modern DOCSIS, though I think my cable modems have occasionally gone to 55 or 56.

 

The orange is receive power. This is generally supposed to go between +8 and -8 or +9 and -9 dBmV.

 

The green line is signal-to-noise ratio (barely visible here since it's on a white background on this particular graph). SNR doesn't really seem to be a very good measure of cable modem signal quality, since it barely moves despite big changes in receive and transmit power.

A not very good photo of my network shelf from earlier this year. I've since redone it significantly. I wanted to document it before I made changes. Compare it to a photo I took nearly a dozen years prior.

The final audio setup in my living room. An ancient pair of Yamaha NS-1000 speakers being driven by an even older Marantz reciever. The source was a MOTU M2 USB audio interface in the other room. I connected it to the Marantz with a really long RCA pair. It worked swimmingly and kept me sane as I dealt with 500 problems associated with moving.

Working hand in hand to provide my home with wireless broadband internet. Woohoo!

I recently shut off my copper landline (after 32 years in this house) and switched to Vonage. I haven't worked out all the bugs yet, but it appears to work okay provided I'm not doing any serious uploading at the time. This setup is temporary, I'm going to get a network switch and move the Vonage box into my kitchen, where I can hook up my cordless. Currently, it's like the 1950s in my house: one corded phone in the living room. All of the gear fits nearly on the art deco bookshelf.

I used my Eye-Fi to get this to Flickr.

 

Moved the Networking and Wii and AppleTV boxes to make room for the new Yamaha Aventage RX-A730. Fits pretty good.

Did you know that your cable signal gets stronger as the weather gets colder? Here's a graph of signal strength on my cable modem from the last day, where it was around 32°F (0°C) at 6 PM yesterday, then got down to about -5°F (-21°C) around 12 hours later. At one point around 2 AM, the cable modem went offline for a few minutes -- it seems that either it or the upstream device wasn't able to keep up with the changes.

 

Blue is transmit power (lower is better). Orange is receive power (higher is better, though it shouldn't really go past +8 or +9). It appears that the received signal more than doubled in strength (since dBmV uses a logarithmic scale, as far as I can tell).

Did you know that your cable signal gets stronger as the weather gets colder? Here's a graph of signal strength on my cable modem from the last month. The bump at the end comes from the cold snap in the last day, where it was around 32°F (0°C) at 6 PM yesterday, then got down to about -5°F (-21°C) around 12 hours later. You can also see that the temperature had been getting warmer gradually in recent weeks. The orange peaks toward the middle of the graph were occurring around 7 AM on cold mornings in February where the temperatures were around zero degrees Fahrenheit.

 

Blue is transmit power (lower is better). Orange is receive power (higher is better, though it shouldn't really go past +8 or +9). It appears that the received signal more than doubled in strength (since dBmV uses a logarithmic scale, as far as I can tell).

 

Roughly the first half of the graph covers a period when I was having lots of trouble with my cable signal. About a week into the graph, I had someone come by to fix it, but it seems that the issues weren't fully resolved until about a week later.

A temporary home theater setup. When he left town in 2016, my friend Dave gave me his 2006 Samsung DLP TV. It was top of the line in its day. It has some issues, but it still works. I plugged my 2021 M1 Macbook pro into it via HDMI and then used a tiny HeadAmp Pico DAC (barely visible on the floor to the right of the left speaker) plugged in to my father's 1997 Yamaha receiver. The speakers are a pair of Yamaha NS-1000s, which I estimate are from the late 1980s. They're not in great cosmetic shape but they still sound amazing. The Pico DAC has a mini USB input (vs the more common micro) meaning I had to get a special USB-C to mini USB cable. These things do not grow on trees.

 

The entire setup is definitely cobbled together from spare parts, but it worked quite well for watching movies in the evening. Compare to the sparse setup I had in January of 2023 and longer term one I had in my room in 2022.

Seriously, either they are throttling me because we use the 'net too much, or Comcast has a serious network issue today.
