Hello friends! I’ve been doing some research for WiFi for a coffee shop and need some advice.

My requirements are as follows:

• guest network and POS network (both WiFi)
• coverage of 3200 sq feet, 280 of which are a separate room
• capacity is 101 people. Assuming worst case scenario (unlikely), everyone walks in with a phone and a smart watch and half the people bring a laptop and the place is full, meaning we need support for 250+ devices

Here are my options as I understand them:

• UniFi Edgerouter X with 3 access points (one in the separate room and 2 in the main area)
• Similar setup but with TP link omada router plus 3 TP link access points in a similar configuration as prior point

More info:

• the owners are not tech savvy so we need a set and forget system
• I am a software engineer with some networking knowledge so set up must be “intermediate” in complexity
• I’m not getting paid for this, I’m just helping out
• it doesn’t have to be fancy but I assume rated for small-business usage since people will go there to watch Netflix, do homework, browse the internet etc.
• potentially prioritize bandwidth to the POS WiFi network for obvious reasons

Which system do you recommend? Any particular models you advise I use? Any other options? I try to avoid off the shelf systems for home because they don’t support the peak amount of users we need.

Any help is appreciated. Thank you in advance.
