PSA: Your business wifi is probably fine, it's your DNS that's the mess
I do side IT work for a few shops near my station in Boise, and I keep finding the same thing: owners paying $200+ a month for faster business internet when the real slowdown is their DNS setup. A bakery owner I help out was on a 300 Mbps fiber plan and still waiting 8 seconds for her ordering page to load, so I switched her router from the ISP default DNS to a public one and it dropped under 2 seconds without a single dollar more. The default servers a lot of providers hand out are slow and unreliable, and nobody checks them because the speed test looks great. Before you upgrade your plan, run a quick DNS lookup test and see what your actual response times are, then tell me what you find.
