Free guest Wi-Fi is expected everywhere now — but an open network with the password taped to the wall is a security risk and a missed marketing opportunity. A&G builds branded guest Wi-Fi hotspots with custom captive portals: the polished login screen your customers see, with your logo and your rules, on a network that is safely separated from your business systems.

A captive portal is the welcome page guests land on before they get online — the same experience you see at hotels and airports, tailored to your business. We design the portal, set up the guest network behind it, and make sure the whole system runs itself: guests get easy, fast internet, and you get security, control, and a professional first impression.
Problems this solves
- Guests and customers on the same network as your point-of-sale, cameras, and files
- A Wi-Fi password on a sticky note that never changes and everyone in the neighborhood knows
- Generic login screens (or none at all) where your brand should be
- One guest streaming video and slowing down the whole business
- No record of who used your Wi-Fi, and no way to turn visitors into repeat customers
When was your router’s firmware last updated?
Unpatched routers and access points are one of the most common ways attackers get into business networks — known vulnerabilities stay open for years on equipment nobody maintains. Every A&G installation includes firmware updates and security hardening, and we keep your network patched after we leave.
What A&G builds
- Custom portal design — your logo, colors, photo background, and welcome message on the login page
- Sign-in your way — simple one-tap access, terms-of-use acceptance, rotating passwords, front-desk vouchers, or email/SMS sign-in that builds your marketing list
- Guest isolation & security — a separate guest network (VLAN) that cannot see your business systems, cameras, or registers
- Bandwidth & session controls — speed limits and time windows so guest traffic never slows your operation
- Terms & liability — an acceptable-use agreement guests accept before connecting
- Analytics & marketing integration — see visit counts and repeat guests, and connect sign-ins to your email marketing
Who this is for
- Cafés, restaurants, and bars
- Retail stores and showrooms
- Salons, spas, and gyms
- Medical, dental, and professional office waiting rooms
- Hotels, guest houses, and vacation rentals
- HOAs, apartment amenity spaces, and clubhouses
- Offices that host clients, vendors, and events
Why businesses call A&G
We run enterprise-grade platforms (including UniFi) for more than 100 Los Angeles locations, so your hotspot is built on the same professional equipment used by hotels and campuses — not a consumer router with a plug-in. One local team designs the portal, installs the network, and supports it afterward.
The experience behind it
A&G’s network experience spans 25+ years — from studio and data-center networks to retail floors and premium Los Angeles homes. Guest access, security separation, and content control are things we engineer every week, not a one-off experiment.
