If you're not going to hook it up to the internet (bridging, access point, etc.), name it something funny or provocative for the neighbors.
For example, I live in a college student neighborhood with a lot of Chinese students. I have an old router that I'm going to use the network name 六四屠殺 which is Chinese for the June Fourth Massacre (the Tiananmen Square Massacre). It's a term banned on the Chinese internet.
Some of us remember one of the first smartphones, the VisorPhone introduced in late 2000. Consisted of a Visor (basically a Palm Pilot knockoff by Handspring) that had a Springboard slot that you could slide a phone attachment into. I have fond memories of using it to bid on an AOL auction while driving down the highway with my ex-wife yelling at me that we were going to be killed...
Truly a product ahead of its time.
