I am running a booth at a convention and need something more reliable than the travel routers and mobile hotspots I have used before. In past events the RF noise was so bad that my device range dropped from about 200 feet to around 10 feet.
I can buy some additional gear but I would like to keep new spending around ~$500.
Connectivity on site:
- Hotel Ethernet: already paid for, but I don't trust that we will really get it
- Hotel WiFi
- A generic Verizon Mobile hot spot (This works as a backup but is painfully slow)
The LAN is what really matters for this setup. WAN is nice, but not nearly as important.
