WiFi Router Recommendation

What's the difference between broad band and dual band?

The terms aren't really related to each other. Broadband is a telecom term that describes transmissions beyond the old, low-speed telco frequencies. So by definition, all routers are broadband.

Most new routers are also dual-band, meaning they operate at both the 2.4 Ghz and 5 Ghz frequencies. The 2.4 Ghz frequency band is a bit crowded and on paper provides lower bandwidth. WiFi standards also allow for transmission at 5 Ghz which is theoretically faster but also does not penetrate obstructions or reflect as well as 2.4 Ghz. I shut off the 5 Ghz option on my dual band routers because I've found it more frustrating than anything else. 5 Ghz-capable devices will continue to try to connect and drop off. By disabling 5 Ghz at the router, dual-band capable devices will connect at 2.4 Ghz which in my experience is more reliable in my application.

Thanks all.
The company is coming in the morning, and the tech said they would get her through this.
Trying to help her out and being 600 miles away and not knowing this stuff makes it difficult .
Thanks, again, for your input.
Best,
