[PLUG] Configuring routing tables to use Wifi over LAN for Internet access

I am in the process of starting a small software development business (yottadb.com) and we are currently squatting in the offices of another company (which is about to change; I will send another e-mail shortly asking for advice on firewalls).

For now, we have a small Ethernet LAN to connect our servers, but not access the Internet, and we use the guest wifi of our host to access the Internet. I'm having a heck of a time getting Linux (Ubuntu / Arch) to prefer the wifi over the Ethernet for the default route. I can delete the default route via Ethernet, and I can change the metrics so that the wifi is preferred, but in both cases, after a few minutes it reverts to preferring the Ethernet. I realize we can put crontab entries to run every few minutes, but I was wondering if there is a better solution. As we won't be squatting for much longer (I hope), I don't want to invest a lot of time in a solution - it's just that the crontab approach seems crude. I did spend time searching on Google and DuckDuckGo, but my search-engine skills have so far not found me the right answer.

Thanks in advance.
