Wall mount Arris Modem

Yes vent holes cover the entire left and right sides, and even most of the top has it too. Before, I used a Ubee DVW326 modem and that had mounting holes on one side, and like the Arris TG2472 it is a vertical modem. I'd like to put this as high as possible, on the ceiling or close to it. Most shelves are short so would need a really tall one.

I was thinking more of a floating shelf.  A floating shelf is basically a small board to mount on a wall.  The natural springiness of a coax cable, however, would make it difficult to keep the modem in place on the shelf.  To combat that, I'd use Velcro strips.

If you don't want to bother with mounting a shelf, you could try zip ties.  I don't know what you used to mount your Ubee, but there are Stud-Mounted Cable Ties on the market.  This is industrial hardware and usually sold in bulk.

If you want to go with cable ties, find a company on the Internet and explain your application in an email.  I've found many company gracious to help me with a project.

A floating shelf is a good idea actually. Where do the Velcro Strips go? And what kind of Velcro strips do you suggest? The thin ones that laptop chargers have or something more thicker than that? Not sure how long the coax cable from the ground is, but I'm assuming it will not reach close to the ceiling.

Mounting a shelf will not really bother me that much, and I never had the chance to put the Ubee on a wall. Also, aren't Stud-Mounted cable ties for cables only, how do you use them to mount the Arris TG2472 itself onto the wall? 

Which type of  company can I find that could help me do this?  How much will they charge for this job? But I think will able to pull this off without any companies doing it. I likely need help though. 

I thought your Ubee was mounted on the wall and has become your preferred location.  So, as of now, you have no screws, bolts or hangers attached to the wall?

I didn't like the idea because you'd have not only a coax strung up the wall, but also power, telephone and any LAN cables.

Why do you want your Arris TG2472 mounted on the wall?  I'll assume better wireless coverage.  Where is it located now?  Can you prop it up on a desktop accessory, such as a small bookshelf or stack of book?

You could also move the Arris to the second floor because the ceiling and floor are the same location.

You could purchase WiFi extenders and position those throughout your house.

There are a few options for you.  Also, there are lots of articles to improve WiFi coverage...if that's why you want the Arris on the wall.

No I do not have any device mounted on the wall and having second thoughts about doing this. That's right, nothing is affixed to the wall that could aide in mounting something there.

Exactly,  that is just a pain and hassle to deal with especially the coax cable and still have all the other cords mentioned too.

I was thinking this will give me better wireless reception, since I have a wifi IP camera which is outside high above the Arris TG2472. The modem is simply on a desk in my room. Yes that's doable, what do you mean by desktop accessory, and where to put that?

My house is only one story so not possible to place it on a second floor, but will look for highest point I can find.

I have a couple already, one for garage, and another looks like will have to setup for that wifi IP camera, this might be my only and best option.

Yes and those articles mention placing the router in a higher spot, but short of the ceiling or wall, where else could that be?
