Remixed from "Google wifi wall mount by haletd".

Added four holes to allow it to be mounted to a peg board with zip-ties.
I also trimmed off the top to save more space on the peg board.

Featured is my piece of scrap peg board mounted with three screws and rubber spacers.
When I need to take the network down, I take out the three screws and physically take it all down. The power strip goes to a battery back-up and and the network cables to to the rest of the house.

I also recommend doing a backhaul when ever possible.

Free tip: If you have a house that was built after 2005, most builders use CAT-5 cable instead of traditional phone line.
I re-terminated all my phone jacks to RJ-45 plugs for about $12.
Hit me up if you have any questions.

Since your Google WiFi has only one port, get yourself nice Ethernet switch.

I recommend a Monoprice 10927, (updated to model 110927)
8 Port Gigabit Ethernet Switch
Rock solid reliability for a great price; no need to pay for extra features that you won't use.

I like these CAT6 Ethernet cables; get some 1ft cables to make the wire management easier: https://www.amazon.com/gp/product/B00IACDFNY/ref=as_li_tl?ie=UTF8&tag=nfkraemer-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B00IACDFNY&linkId=da2d25953b1d2537a642dde8b87d483b

While you're at it, grab yourself another WiFi Mesh Point (NLS-1304-25) to strengthen your mesh: https://www.amazon.com/gp/product/B00IACDFNY/ref=as_li_tl?ie=UTF8&tag=nfkraemer-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B00IACDFNY&linkId=da2d25953b1d2537a642dde8b87d483b (Don't pay more than $99 for an additional one).
